LEGO Technic 42177 MOD – Rural Road Drain Cleaning Attachment The Mercedes G Class Ute built from LEGO Technic set 42177 has quickly become my favourite platform for modular attachments. With the rear tray-mount system now well-established, using the same two fold-up connection points across all my accessories, it’s become incredibly easy to design and swap functionality on the fly. Today, I’m showcasing the newest attachment in the lineup: the Rural Road Drain Cleaning Attachment. Why a Drain Cleaner? Living in rural areas, drains and culverts are always filling with debris, leaves, sticks, gravel, and whatever else washes down in a storm. Real-world council trucks often have dedicated jetting or scoop tools for clearing roadside drains, so creating a Technic-scale version felt like the perfect next step for the 42177 G Class Ute. Plus, this attachment brings a whole new kind of mechanical interaction to the model, something practical, functional, and very satisfying to operate. Attachment Overview Just like the existing implements, the drain cleaner locks securely onto the tray via the fold-up twin point connection system. It installs in seconds. When folded down for operation, the attachment extends over the side of the ute and places the cleaning head right where you’d expect a drain to sit.

That is very cool, great video.

The colour vomit puts me off.

Motorbikes are not my thing but this looks cool and engine is a nice touch.

Colours “work” and while not ground breaking, looks interesting enough. I’m guessing fake engine and HOG steering?

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. https://paulbtechnic.blogspot.com/2025/11/review-lego-technic-42209-b-model.html

Amazing work :)

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.

I really like this. The green of the deck really stands out.

Amazing work.

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.

That looks "interesting"...

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.

Very cool.

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.

Car looks cool and sounds great but price is really creeping up :(

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.

Great work as always and I love that you also made the B model.

This is a great C model, it looks awesome.

The mid 90's was the peak, while I enjoy studless it is just not the same.

That is great news :)

Late to the party, but finally got this set :) https://paulbtechnic.blogspot.com/2025/11/review-lego-technic-mercedes-benz-g-500.html

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. http://paulbtechnic.blogspot.com/2025/11/lego-technic-articulated-tractor.html

This is great, I might get another copy of 42213, just to build this :)
