John Deere Axron


What started out as a little tractor and trailer has grown into the Thirdwigg Farm! And it needed a bigger tractor.

Free instructions are available at Rebrickable.com.

I started with a simple, small, row tractor that I called the Atmos. This tractor was mid scale and in addition to steering and a fake engine like most of my builds, it featured a front implement mount, rear three point hitch, rear PTO, and rear Pneumatic PTO. Little did I know how the tractor would grow into a lot of other tractores, trailers, impliments, and farming support vehicles. At some point, I found myself interested in making a larger tractor, and I have always loved the Claas Xerion. The Claas been done in Lego Technic before, so I went the John Deere styling route for my build.

The tractor had to integrate into the other builds, so the front and rear mount and PTO placement dictated a couple of the hard points. I built the tractor with four wheel drive, and four wheel steering. A four cylinder fake engine is placed under the frond hood above the front axle. The rear most cylinder does not move as the crankshaft would have run into the steering unit, and any change I tried to fix it made for an ugly hood. A worm gear actuated rear three point hitch allows for implements to be mounted to the tractor.

The steering is controlled by a HOG light at the top of the cab, which caused some headaches for placement as I wanted the cab to be able to rotate. There is a small gear on the right of the tractor that controls the rotation through and internally mounted worm gear. Getting the cab to rotate in the right spot, without hitting anything, and while still having the pneumatic pump, required endless test rotations.

Since this is a Thirdwigg Farm tractor, there are many options to pair with this tractor, all with free instructions. My favorite is the Hookloadr trailer, but the Tandem Disc looks great too. Free instructions are available for all the options, so feel free to make your own farm.

It is always fun to make another tractor and this one was no exception. I wish the drivetrain was a little more smooth, but the rest of the tractor worked flawlessly. And it looks fantastic. Coupled with a trailer, makes it look strong and purposeful. And the rotating cab is so much fun to play with. We’ll see what gets added to the Thirdwigg Farm next!

Happy building!
