hi men, a few years ago i helped a co-worker acquire a C160 with a tiller. i did my best to rig a hardware store system to lift the tiller. any way my co-worker reported that the tiller was leaking. i picked the tractor up and when i got it home i realized this old tractor needed some additional maint. both axle seals were leaking. so i pulled the hubs and replace those. the brake band seal was leaking so i replaced that. oil change, air filter and fuel filter for the kohler. grease all the zerks. then i replaced the tiller seals. next, i installed one of lowells rear rockshaft kits. WOW! fits perfectly. the tiller now has plenty of travel to till deep. yet, still when fully raised up it has plenty of ground clearance for traveling back to the garage. the quality of the hardware in his kit is first class. not exactly cheap price but, you get what you pay for in this life. hope this helps you guys mike in mass.
