Electric Motors & Transmission

The drive on the mini tractor was a bit experimental and used 4 electric motors driving through toothed belt speed reductions to a chain sprocket on roller chain drive rim. This was effective in generating the large overall reduction ratio and produced an interesting buzzing noise in operation.

Front & Rear Wheel Assemblies

Doubled up mountain bike wheels for the rear drive and BMX type wheels on the front. All with existing ball races stripped and replaced with fixed through axles.
