DRIVE MOTORS & WHEEL ASSY'S
Click on Drawing Images - Password is:
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.
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.
