My Land Pride RCR1860 did not have a C clip. After I got the bolt out I had to apply solvent and wiggle it back and forth and drive the clutch assembly rearward with a 1" pipe and 3lb hammer. Finally got it free enough to go forward and off the implement shaft. I'm putting Easy PTO connectors on the shafts on the rotary cutter and the rear finish mower, FDR1672 as well as the output shaft from the L2501. I am completely disassembling both PTO shafts for the first time. De-greaser and power wash then greasing the inner shaft and the universal joints. The UV joints have seen the grease gun but not the half shaft. It was stiff to collapse and expand exasperating the connection dance with the tractor. Sometimes I could get a shaft connected in 20 seconds and sometimes 45 minutes with sweat in my eyes before getting someone to push while I collapsed the snap collar. I'll be slipping the clutch for the first time since the factory, if the dealer didn't bother doing it. They didn't fill the front axle so I doubt the would slip the clutch.
