Have tried many types of mowers on our hillybilly farm. Rear finish mower does the best. Problem is wear and bending of the wheel spindle shafts. Compact 4x4 tractor with tight turning adds to the problem. To trim there is lots of back and forth always rotating the mowers spindle. Liberal greasing didn’t help. Replaced the 1” shafts with 4140 tool steel was better but still wore and bent over time. Slight wear or bend amplified the problem. Support arms wore out, high $$$ to replace and spindles too.

Changed to trailer bearing axles and hubs solved my issues. Making plates to mount the new hubs easy with a new plasma cutter. Money saved from buying OEM parts paid for the cutter.
Surprised more people don’t have a problem with the spindles. Guess cutting open, flat areas less of a problem. HST is the best for finish mowing.
10 years on a 22+ year old mower going strong. Don’t miss greasing the spindles either.

3500# axle/hubs. Bought set of 4 on eBay $200…about 10 years ago. Made template to cut all the 1/2” mounting plates the same. Can put washers on lug bolts for some height adjustment. Like tilting forward makes for a better cut requiring less hp. Once we figured our height on the OEM spindles didn’t adjust anyway.
