The rear wheels are conventional 18x850x8 turf tyre/wheel units.
They are mounted on a weld-less drive hub assembly which
incorporates a 3/8" pitch (#35) roller chain drive sprocket. The
rear axle is 25 mm diameter un-stepped steel shafting and runs
on inexpensive needle roller bearings mounted in the hardwood
bearing blocks in the chassis. The axle is also fitted with ball
thrust bearings to carry axle thrust loads that arise during
tractor cornering.
