2025 – My LEGO Technic Year in Review
As 2025 draws to a close, it’s the perfect time to look back at a massive year of building, modding, experimenting, and expanding what’s possible with LEGO Technic. Despite a slow start, the year turned into one of the most creative and productive periods of my Technic journey.
A Slow Start – But Worth It
Just like in 2024, the first few months of 2025 were quiet.
Family life, commitments, and everything else demanded my attention, so Technic projects paused for a while. But that break actually helped reset my focus, and when I returned, I came back with far more clarity and direction for what I wanted to build.
Quality Over Quantity
Across the whole year, I built 14 models, but this time, it wasn’t about churning out builds.
Only 4 were built as “A-models.”
The rest were C-models or full MOCs, crafted from the parts of sets I already owned.
More than ever, I found myself looking at new Technic sets not as finished products, but as platforms, raw material with potential. What they could become mattered more than what the box showed. This shift shaped everything I built in 2025.
Pushing the Limits of 42177
The Mercedes-Benz G 500 (42177) became the backbone of my Technic projects this year. What started as a standard set evolved into a completely re-engineered platform with interchangeable rear attachments, a redesigned tray, and a fully functional PTO system.
The rear PTO, added retrospectively, became the heart of the system and unlocked endless attachment ideas.
I designed multiple rear-mounted modules, including the G-Class Ute conversion, a new tray layout, and various snap-on functional units.
One of the highlights was the Rubbish Loader Attachment, driven by a small linear actuator via the PTO, complete with a purpose-built loading ramp to keep the load contained. A simple concept, but one that dramatically increased functionality and play value.
42177 wasn’t just a model this year, it was a platform for innovation.
Non-LEGO Brands – Some Hits, Some Misses
2025 also saw me explore a few non-Lego brands.
Results were mixed: some offered interesting parts or fresh building styles, while others didn’t meet the quality, clutch power, or durability I expect for Technic builds. Still, it was a worthwhile experiment that gave me a better understanding of what’s out there beyond LEGO.
TechBuildDB – A Huge Step Forward
Another major milestone was the development of TechBuildDB, my custom tool for managing MOCs, attachments, notes, and design logs.
What started as a basic idea evolved throughout the year into a proper web app with features like:
Record creation and editing
Photo uploads
JSON export
Indexed navigation
A cleaner UI designed specifically for Technic workflows
It’s becoming an essential tool for planning and managing my builds, and it will only get better in 2026.
A Shift in Design Philosophy
Somewhere along the way, I realised my whole approach to Technic had changed.
Rather than building display models, I focused on:
Designing platforms
Creating attachment ecosystems
Prioritising functionality over aesthetics
Building mechanisms inspired by real machines
Ensuring everything was modular, durable, and easy to swap
This mindset gave me far more creative freedom, and it made 2025 one of my most rewarding Technic years yet.
A Milestone: My 200th Blog Post
This post marks a big moment, my 200th blog entry on PaulB Technic.
There’s no better way to celebrate that milestone than with a full-year reflection on everything I’ve built, learned, and experimented with.
It feels like the perfect way to round out the year.
Looking Ahead to 2026
If 2025 was about building foundations and exploring new ideas, 2026 will be about expansion.
Plans include:
More attachments for the G-Class platform
A second-generation PTO system
Possibly an all-new base vehicle
Further development of TechBuildDB
And diving deeper into new Technic mechanisms and building styles
2025 has been a year of growth, not just in models, but in creativity, mindset, and engineering.
Here’s to an even bigger, more innovative 2026!
LEGO Technic 42177 MOD – Rubbish Loader Attachment
One of the most enjoyable parts of working with my LEGO Technic 42177 MOC Ute, is discovering just how versatile the platform can be when you start adding custom attachments. My latest upgrade is a Rubbish Loader Attachment that connects neatly to the rear of the ute and adds a surprising amount of function, character, and play value to the model.
This attachment is driven by the rear PTO, which powers a small Linear Actuator responsible for lifting the loading arm. It’s a simple yet effective mechanical setup that feels right at home on this MOC, smooth, controlled, and fully mechanical.
Powered Lift via Rear PTO
The core of the system is the compact LA mounted in the center of the attachment. The rear PTO transfers rotation from the truck’s side-mounted grey control to the actuator, giving you a fully functional lifting mechanism. This makes the rubbish loader feel consistent with the rest of the Technic ethos: realistic motion, mechanical authenticity, and solid feedback during operation.
Smart Loading Ramp Design
A key feature is the loading ramp, designed to keep the rubbish load stable while lifting. The geometry of the red and yellow arm ensures the bin or payload stays in place as the mechanism raises. No slipping, no bouncing, just clean, controlled motion. It also makes the attachment surprisingly practical in play, as you can actually scoop, lift, and tip various items.
A New Level of Playability
With this attachment, the 42177 MOC Ute gains yet another functional layer. It sits securely on the rear mount, uses the existing PTO system, and feels like a natural piece of equipment your Technic utility truck would realistically use.
Most importantly, it adds fun. Kids (and adults) can now drive up to a pile of parts, scoop them up, lift them into the tray, and repeat. It turns the ute into a multi-purpose workhorse, and complements the other attachments I have already built.
Conclusion
The Rubbish Loader is a small but meaningful upgrade that shows just how adaptable the 42177 MOC Ute platform can become with a little creativity. By integrating clean mechanics, practical function, and a playful design, this attachment strengthens the model’s identity as a true modular utility vehicle.

LEGO Technic 42177 MOC – G-Class Ute Update (December 2025)
Over the past few weeks I’ve been refining my LEGO Technic 42177 G-Class Ute MOC, pushing it even further into the role of a true multi-purpose workhorse. December has brought two major upgrades that significantly improve both the look and the playability of the model: the removal of the tray sides, and the addition of a fully functional rear PTO.
Tray Sides Removed – More Space, More Possibilities
One of the first changes this month was removing the tray sides. It might sound simple, but it dramatically changes what the G-Class Ute can do.
Without the tray sides: Larger attachments can now be mounted without hitting the panels.
Attachment swapping is far easier, no twisting or angling pieces just to make things fit.
The ute has a more realistic utility look, with an open work tray that suits a modular equipment system.
This change alone opened the door to more ambitious rear-mounted tools and accessories… which leads to the biggest upgrade.
Rear PTO Added – A Game-Changing Upgrade
The most significant improvement is the addition of a rear Power Take-Off (PTO), driven by a grey knob on the left side of the vehicle. Turning this knob powers a red rear PTO output ready to drive mechanical attachments.
This feature wasn’t in the original plan. In fact, it was added retrospectively, after the ute had already been heavily modified a few weeks ago, making the process more challenging.
Because so much of the rear section had already been redesigned, several components no longer lined up with where the PTO needed to run. That meant:
- Multiple attempts to align both the input and output shafts
- Reworking bracing and support so the mechanism remained strong
- Adjusting the aesthetics so the PTO didn’t stand out or look bolted-on
It took a lot of trial and error, but the end result is worth every minute spent on it.
The new rear PTO has transformed the model. It turns the G-Class Ute into a proper modular machine, more like a scaled-down Unimog, with the capacity to run mechanical tools straight from the vehicle.
I already have several new PTO-driven attachments planned. Even better, I’m intending to revisit some of my older attachments and redesign them so they can make use of the new PTO connection.
With the tray now fully open and the PTO functional, December’s update sets the stage for a whole new wave of attachments. Expect more detailed designs in the coming months, each taking advantage of this new capability.
The 42177 G-Class Ute continues to evolve, and this update marks one of the most significant improvements so far. More power, better modularity, and increased play value… exactly what a Technic MOC should deliver.

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:
-
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. -
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. -
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. -
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. -
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
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.
