I have an HRR216 with a weak self propelled drive.
The mower propels fine on the driveway but in the grass it has weak to no drive/propel. When I raise the rear wheels off the ground and engage the drive, I can stop the forward motion of the "left" wheel by applying the sole of my boot to the "left" wheel; I cannot stop the "right" drive wheel, no matter how much force I apply with my boot on the wheel. I assume that because the "right" wheel cannot be stopped that the transmission is functioning, properly. I assume that because "left" wheel can be stopped, that either (a) the ratchet and/or spring or (b) a worn/elongated bushing are at fault.
Question #1: are there other possible/likely faults of the lack of drive power in the "left" wheel besides the ratchet/spring or elongated bushing?
I removed the "left" wheel, washers, spring clip and pinion gear. I found that the ratchet was stuck, a bit, in its slot, in the drive shaft. I tried to pull the spring out of its hole in the center of the slot area. I could not remove it but its not rusty and seems to function OK ... so I am not going leave it alone, for now.
Question #2: how do I remove the bushing (see PDF, attached) located on the drive shaft, between the pinion gear (when installed) and before the height adjuster arm?
Question #3: after removing the aforementioned bushing, how do I remove the height adjuster and whatever else I need to remove to access and replace (as needed) the bushing that is seated in the deck and surrounds and the drive shaft?
Thanks, in advance!
