Bigger Than a Blue Whale

Blue whales are the giants of the animal world, averaging 150 tons — and some truly massive ones tip the scales at 180. But in the world of heavy machinery, there’s an equally impressive beast: the ACCO Super Bulldozer, weighing a mind-blowing 183 tons. Imagine all the gears, parts, and mechanical magic packed into that monster! Tempted? Our DIY bulldozer, Terrain Titan, is calling your name. One of the most ambitious DIY builds out there, it’s a hands-on challenge even for seasoned pros.

1715 pieces. No joke.

But the Terrain Titan isn’t just big — it’s serious fun. With next-level detail and hands-on interaction, this DIY bulldozer looks like a real dozer and even acts like one. A massive frame. A working track tension system. A maneuverable blade and rear hook. And a detailed operator’s cab with opening doors, a seat, and a steering wheel — because details matter. To start the bulldozer, simply wind the knob behind the cab, then move the control lever to the ON position. Fully wound, Terrain Titan can travel up to 20 feet under its own power.
Warning: a serious build is about to begin!
The Terrain Titan by WoodTrick is a specialized 3D wooden constructor that blends realistic design, exceptional detail and complex internal mechanisms. With a record-breaking 1715 pieces and the highest difficulty rating, it stands as one of WoodTrick’s toughest builds to date. If you’re ready for a rewarding DIY project that truly tests your skills, expect to spend around 16 hours assembling this impressive machine.

The Terrain Titan replicates the mechanics of a real bulldozer in stunning detail. You’ll assemble the tracks, wheels, rollers, and the tensioning mechanisms that let your DIY bulldozer actually roll — up to 20 feet on a full wind. Up front, a massive semi-spherical blade and a heavy-duty hook at the rear let you handle loads realistically, both moving smoothly back and forth. A meticulously detailed operator cabin and a heavy-duty hydraulic system show off the precision engineering packed into this wooden powerhouse.


Who will get the most out of the Terrain Titan? If heavy machinery, clever gears, or a hands-on DIY challenge gets your heart racing, this 3D model is made for you. And here’s an important bonus: our DIY bulldozer is safe for both you and the environment. Like all our models, it’s crafted from sustainable plywood and can be fully assembled — no glue or extra supplies needed.
