Lego Technic 42177 MOD - Mercedes G Class Ute - Rear Plough Attachment

Over the past few weeks, I’ve been steadily expanding my custom ecosystem of attachments for my LEGO Technic 42177 MOD Mercedes G Class Ute, a C-model / Mod, derived from the Mercedes G Wagon set. The tray-mounted connection system has proven incredibly versatile, and today I’m excited to share the latest addition: the Rear Mount Plough Attachment.

This attachment follows the same design philosophy as my previous builds, compact, functional, and fully compatible with the two fold-up mounting points integrated into the ute’s tray. It slots in cleanly, deploys smoothly, and adds a rugged new capability to the vehicle’s growing lineup of field tools.

Design & Concept

The rear plough is inspired by agricultural and off-road recovery ploughs. The idea was to create something that looks purposeful behind the G Class Ute while still being mechanically simple enough to build and sturdy enough to function during play.

Key features include:

Folding Mechanism

Just like the other attachments in the series, the plough folds up for transport and down for operation. When stowed, it sits neatly against the rear of the tray without interfering with suspension articulation or steering.

Dual-Mount Compatibility

The attachment uses the now-standard two fold-up connection points on the tray. This means it can be swapped in seconds with any of my other accessories—no rebuilding required.

Manual Actuation

A simple lever/beam linkage allows the plough to be lowered into position. The mechanism locks in place so the blade doesn’t flop around while driving.

The Mercedes G Class Ute MOD has become a surprisingly capable platform for modular tools. Its tray offers stability, its scale is just right for functional attachments, and its rugged look works well with equipment like drills, cherry pickers, and now ploughs.

This attachment was designed to:

Keep weight balanced

Preserve full suspension travel

Avoid interference with the rear bumper or lights

Maintain the overall clean aesthetic of the ute

The final result is an attachment that looks like it belongs on the model rather than an add-on.

Play & Display Value

Whether you’re ploughing through imaginary soil, clearing a miniature access track, or lining it up for a photo shoot, this attachment adds another layer of realism and versatility to the G Class Ute.

For display, the plough in its upright transport position gives the truck a purposeful expedition look. For play, lowering it brings a whole new dynamic to the rear of the model.

Review - LEGO Technic 42209 B Model - Backhoe By Kilmarnock

I think the Backhoe Loader B-model of Lego Technic set 42209, by “klimax” is a fantastic build, it is smart, efficient, and fun. It delivers a lot of what makes Technic great: real mechanical functions, clever reuse of parts, and a tangible sense of “engineering”. While it’s not as grand or heavy as the original 42209 loader, it doesn’t try to be; instead, it trades size for versatility and ingenuity.

If you own the 42209 set (or are considering it) and enjoy tinkering with alternate builds, this MOC is absolutely worth the time to build. It offers a different experience from the official model, more compact, but still functional and rewarding. Please see my video below.

LEGO Technic 42177 MOD – Mercedes G Class Ute - Cherry Picker Attachment

I have recently been working on my latest attachment for my LEGO Technic 42177 Mod Mercedes G Class Ute, this is a cherry picker.

It has two features:
- The black gear controls the lifting and lowering of the cherry picker arm.
- The red connector controls the rotation of the turntable.

Update - 9/12/2025:

Following some other changes to my 42177 Mod Ute, I have now modified this to use my new rear PTO output, to rotate the turn table, video is below.

LEGO Technic 42177 MOD – Mercedes G Class Ute - Towing Attachment MK2

Since the last post, I’ve made a number of substantial improvements to the G-Class Ute mod, particularly around the lifting module. Here’s what’s new:

1. Swapped to Pneumatics
   I replaced the earlier small linear actuator (LAs) with a full pneumatic system. The pneumatic cylinders now deliver a much stronger, smoother motion, giving the lift better stability under load and more realistic behaviour. This change dramatically increases the lifting strength and eliminates some of the flex and lag I was seeing with the LAs.

2. Revised Mounting Points
   To accommodate the new cylinders, I re-engineered the mounting structure at the rear of the tray. The new mounting brackets are more robust, and they better distribute the load into the reinforced chassis. This has reduced unwanted flex and made the attachment more rigid when lifting and lowering.

3. Redesigned Forks & Connectors
   The forks on the lifting module have been updated and redesigned, using stronger beams and more efficient connector geometry. I swapped in more Technic connectors that can better handle the bending forces. The result: better lifting capacity, less sag, and greater reliability when carrying heavier weights or awkward loads.

4. Improved Lifting Capacity & Stability
   With the pneumatic upgrade and restructured forks, the lift can now handle significantly more weight without bottoming out or slipping. The entire lifting module feels more “locked in”, even at full extension the system remains stable and controlled, rather than wobbling or drooping.

5. Performance in Action
   In practical testing, the pneumatic lift now delivers a much more satisfying “rise/fall” feel. It’s responsive, doesn't lose pressure mid-lift, and holds position very well once raised. When lowering, the motion is controllable and smooth.

LEGO Technic 42177 MOD – Mercedes G Class Ute - Drill Rig Attachment

Following the towing module, my Mercedes G Class Ute (a MOD / C-model based on LEGO Technic set 42177) now has its second functional attachment: a compact and fully operational Drill Rig. This one adds a whole new capability to the ute and was a fun challenge to design.

Universal Mounting System:

Just like the towing attachment, the drill rig connects using the two fold-up mounting points built into the tray. These points are quickly becoming the standard interface for all future add-ons, making it easy to swap attachments depending on the job.

Designed to Fold for Use and Transport:

The entire drill rig is built to fold down into position when drilling, and fold back up for transport, keeping the ute looking clean and tidy while driving. The mechanism is simple but effective, and it locks into place nicely in both orientations.

Functional Features: 

Despite only taking a few hours to design, this attachment is surprisingly capable:

• Rotating Drill Head: A side-mounted wheel at the top of the rig allows you to spin the drill manually. It has a satisfying feel, and the gearing gives it a smooth, realistic drilling motion.

• Adjustable Drilling Height: The drilling head moves up and down as required, letting the rig simulate drilling different depths. It adds a great bit of playability and makes the attachment feel like a real working tool.

Build Time: 

The complete design and build took 3.5 hours, making this a quicker project than the towing attachment but still packed with functionality.

Final Thoughts: 

This drill rig feels like a natural next step in expanding the G Class Ute’s versatility. With two attachments now complete, I’m already planning more tools and equipment for the mounting system.

LEGO Technic 42177 MOD – Mercedes G Class Ute - Towing Attachment

The Mercedes G Class Ute project, my MOD / C-Model based on LEGO Technic set 42177, has officially received its first functional attachment, a purpose-built towing module. This add-on transforms the ute into a capable little workhorse, perfect for hauling other models around.

Designed to Integrate Seamlessly

The towing attachment connects securely to the tray using two fold-up mounting points built directly into the ute’s design. These points were planned early in the build, making this attachment the first test of the system. I’m happy to say it works exactly the way I hoped, strong, tight, and easy to connect or remove.

Two Practical Functions

Despite its compact size, the attachment includes two fully functional mechanisms:

1. Tow Winch with Locking Feature

A manually operated tow winch sits at the heart of the attachment. It includes a simple but reliable locking mechanism to hold tension once the vehicle being towed is secured. This keeps everything steady during movement.

2. Drop-Down Towing Arms

The towing arms fold down into position when needed, providing a stable support for the vehicle being towed. When not in use, they fold neatly back up, keeping the ute’s rear clear for normal driving. This feature alone adds a lot of versatility and realism to the setup.

Build Time & Process

All up, the design and build took around six hours. Most of that time went into getting the fold-up mounting points and the winch mechanism to feel smooth and reliable. Once the geometry was right, the rest fell into place naturally.

In Action

The photos below show the towing attachment in use, hauling my Ford Raptor Technic model. The combination looks great and performs just as well—exactly the sort of functional add-on I wanted for the G Class Ute project.

LEGO Technic 42177 — MOD / C Model to Mercedes G Class Ute

I’ve been wanting to convert the LEGO Technic set 42177 into a proper G-Class style Ute for a while. This mod combines structural tweaking, custom Technic frame work, and a completely new tray build. Below is the full progress log, including the hours spent and step-by-step development.

---

Initial Pull-Down (1 Hour)

The first step was a complete teardown of the rear of the donor 42177 model cabin. Panels, rear cab and rear section, and decorative elements all came off so I could work with the bare Technic chassis at the rear.

---

Sorting the Parts (30 Minutes)

With everything disassembled, I sorted all beams, connectors, panels, gears, and pins. This helped massively during the rebuild phase, especially for the custom tray and frame work to support this.

---

Cabin Fixes: Rear Door Frame & Roof (1 Hour)

Before moving to the tray, I fixed a few structural quirks in the cab.

• Reinforced the rear door frame with various connectors, for better rigidity and to give the front doors something to close against.

• Strengthened the cabin roof to prevent flexing and to prepare for the new sports bar later on.

---

Chassis Reinforcement + Tray Design & Build (15 Hours)

This was the biggest part of the mod.

Chassis Reinforcement

To support the new Ute tray, the Technic chassis needed extra bracing:

• Added long liftarms to strengthen the spine

• Reinforced the rear section

• Improved cross-beam stability to handle the tray footprint

Tray Design

I tried a few tray concepts before settling on a cleaner G-Series style. The goal: sturdy, balanced, and authentic to Technic proportions.

Tray Build

Using beams, panels, and angled connectors, I built out:

• The main tray frame

• Side rails

• Tail section

• Mounting points for the future accessories, these flip up from the bottom of the tray.

Test Fit

Mounted it onto the chassis to check alignment and tweak clearances.

---

Front Nudge Bar + Sports Bar Installation (2 Hours)

Next came the custom Technic nudge bar, built from liftarms, axels and connectors. After that, I installed the tray sports bar, giving the model a proper rugged Ute silhouette.

---

Tool Box, Jack Mount & Axle Fillers (2 Hours)

To finish the build with some functional Technic details:

• Added a Technic tool box mounted on the tray

• Created a Jack, which can be used to lift the model.

• Built side axle fillers to close the visual gaps between tray and chassis, giving it a clean, finished look

---

Final Thoughts

Total build time: 22.5 hours
End result: a tough, clean, custom G-Series Technic Ute built from set 42177, with a reinforced chassis, new tray, accessories, and improved proportions.

This MOD not only improves the functionality and display presence, but also transforms 42177 into something uniquely yours. All the normal features of the 42177 A model, such as hand of god steering, working steering wheel, R-N-D gear box, high / low transfer case and both the locking diffs still work as on the A model. 

I plan to use this as a base for some interesting attachents and different features.

Review - LEGO-Compatible Technic Ford Raptor Ute

The LEGO-compatible Technic Ford Raptor ute is an impressive third-party building set that aims to capture the aggressive styling and mechanical feel of Ford’s well-known off-road performance truck. While it’s not produced by The LEGO Group, it still offers a surprisingly solid building experience, especially for fans of Technic-style vehicles.

Design & Aesthetics

The model faithfully mirrors the real Ford Raptor’s tough, wide-stance look. The shapes, curves, and grille details are well executed for a brick-built model, and the bright orange bodywork is eye-catching. Paneling fits together cleanly, though the quality may vary slightly compared to genuine LEGO elements. The scale also feels right: big enough to show off on a display shelf but compact enough to roll around and enjoy as a functional model.

Build Experience

For a third-party kit, the build is surprisingly enjoyable. The instructions are generally clear, and the internal mechanisms feel very “Technic-like.” Some parts may require a bit more force or patience to connect, depending on manufacturing tolerances, but overall the building process is satisfying.

Features & Functions

This Raptor ute includes several mechanical functions commonly found in Technic-style builds:

• Working suspension on all wheels

• Steering controlled through a gear or roof-mounted knob

• Opening doors, bonnet, and tailgate

• A detailed interior and engine bay with a V6 Engine
  

• Front Mounted Winch

The suspension is one of the highlights, it compresses smoothly, giving the model a realistic feel when navigating bumps and obstacles. The steering mechanism is functional, though slightly stiffer than what you might expect from official Technic pieces.

Parts Quality

The quality ranges from good to very good for a LEGO-compatible set. Most pieces have minimal flash marks and connect securely, though a handful may feel slightly looser or tighter than official bricks. Colour matching is consistent across the set, which is a pleasant surprise.

Value

Given the lower price point compared to official licensed Technic kits, this Raptor ute offers excellent value. You get a large, feature-rich vehicle with a complex build at a fraction of the cost of a branded model. For builders who don’t mind using compatible elements, it’s a strong option.

Overall Verdict

The LEGO-compatible Technic Ford Raptor ute is a solid, enjoyable set that punches above its price. It’s not LEGO, and doesn’t try to hide that, but it delivers a rewarding building experience, impressive functional features, and an attractive completed model. If you’re open to third-party Technic-style kits, this one is worth a look.

Welcome to My World of LEGO Technic

Hello, I’m the author behind PaulBTechnic Blog, where I dive into the world of building, modifying and inventing with Technic sets, C-models, MOCs and more. This space is my creative workshop, my testing ground and my playground all rolled into one.

Why I Build

There’s something about the structure, the mechanics and the potential of Technic that gets me every time. Rather than simply following instructions, I love to question: What else could this set become? How can I mount additional attachments? How can I make something modular, reusable, adaptable?

For example, in my recent project with my “Off Road Utility Truck (ORUT)”, I engineered a base chassis that supports multiple attachments via a Power Take-Off (PTO) system at the rear. It’s a design that lets me swap in a slasher, a grader, a rubbish loader, you name it.

What You’ll Find Here

• Set Reviews & Alternate Builds: I examine official Technic releases and then explore how to re-use the parts for alternate builds (C-models) or full-blown MOCs. 

• Modular Design & Attachment Systems: My signature is building a core platform (like the ORUT) and then designing attachments that plug in seamlessly. The aim is not just “one build” but a system for many. 

• Workshop & Build-Space Optimisation: Because parts, beams and motors quickly multiply, I talk about how to organise your space, route your build workflow, and keep creativity flowing. 

My Approach

• Functionality meets play & display: I want my builds to work, steer, lift, drive, swap attachments, but also look good in display.

• Re-use & rethink: Every build is an opportunity to maximise the parts at hand. Rather than buying all new pieces, I often re-engineer what I already have.

• Modular & scalable: I design with the future in mind, the ability to add on, interchange, evolve.

• Share & learn: This blog isn’t just a show-and-tell. I want to share my process, my errors, my successes so that other builders (and new ones) can learn, adapt, and be inspired.

A Bit About Me

I’ve long been drawn to electronics, mechanics, radio systems and making things work, whether in software consulting, radio-monitoring hobbies or building physical models. With LEGO Technic, I found a playground that combines structure, systems, problem-solving and creativity. Here, I’m putting that mindset to work: You’ll see detailed build write-ups, a design philosophy behind the attachments, and a push to expand what the standard sets can deliver.

What’s Next

With the ORUT as a proven base, I’m turning my attention to new attachments, more complex modules and perhaps branching into even bigger scale builds. Think: agricultural gear, off-road expedition modules, multi-tool vehicles. The goal is to keep pushing. 

If you’re a Technic fan, curious builder or someone who enjoys seeing how structure and creativity intersect, you’re in the right place. Let’s build, experiment and evolve together.

Review - LEGO Technic Mercedes-Benz G 500 Professional Line (42177)

The LEGO Technic Mercedes-Benz G 500 Professional Line (42177) captures the rugged elegance and engineering precision of the real vehicle in an impressively detailed Technic build. I had a great time (mostly) building this and the end result is impressive.

---

Cons

• Lengthy, occasionally confusing build: Some steps require careful attention and may frustrate less experienced builders.

• Clearly aimed at adults: While not necessarily a bad thing, this isn’t a beginner-friendly Technic set.

• Tight lever access: Some feature controls are a bit awkward to reach once everything’s assembled.

• Weak door connections: The doors have a bit of flex, especially near the top, which slightly detracts from the solid feel of the model.

---

Overall

The Mercedes-Benz G 500 Professional Line is a fantastic Technic set, a strong combination of looks, functionality, and value. It’s both a rewarding build and a striking display piece. For anyone serious about LEGO Technic or looking for a premium, realistic model with excellent MOC potential, this is a must-buy.

⭐ Rating: 9/10 – Great design, great value, and a joy for any Technic enthusiast.

LEGO Technic Articulated Tractor - November 2025

This build started life as the LEGO Technic 42121 B-Model, but it has been heavily modified and redesigned into an articulated tractor, something that is compact, functional, and full of character.

Features

• HOG (Hand of God) Steering: Smooth and precise control from the top of the cab, making it easy to maneuver the tractor through tight spaces.

• Opening Engine Cover: The hood flips open to reveal a working engine connected to the front axle, showing off the mechanical detail inside.

• Rear Mounted Lift Point: Designed for versatility, this rear hitch system allows for a range of attachments. I’ll be designing and building several different tools and implements to connect here soon.

Design Notes

Transforming the original 42121 B-model into this tractor was an enjoyable and creative process. The articulation joint adds a lot of realism and play value, and the proportions feel just right for a mid-sized off-road tractor. The color scheme, mostly yellow with black accents and a few pops of red and grey, gives it a rugged industrial look.

I’m really happy with how this one turned out, a compact, functional Technic build with plenty of room for customization and future add-ons. Stay tuned for the next post where I’ll start developing some of those rear attachments.
