Since there is no grinding noise, if the problem is in the gear box it isn't too severe. There is a slight possibility that a tooth or two has been broken off one of the gears. But it sounds more like you have a worn drive belt. Most of the time when the tines don't grab or they slip it is because the drive belt have become worn in some way. If it is suppose to be a one-half inch wide belt it could have thinned to a three-eight inch allowing the belt to drop further into the pulley than needed, or it may be "sloppy", not tightening enough to operate the tines if it has stretched. The right belt is very important and is an easy fix. I hope this helps.

I presume you opened the port and removed the grade 8 placement bolt? If you have then you need to polish the shafts with 400 then 800 sandpaper, clean then lube them before trying to slide thru the support bearings. If your tine shaft is bent? your screwed, or just remove the shaft seals with a screwdriver and replacing them without removing the shaft. REmember to put a thin coat od RTV arround the outer lip to help make a better seal

SOURCE: How do we get the
How are you today? I hope well. This is a pretty simple project to get wheel off.
To remove tire & hub from tiller,place tiller on a secure jack or stand,remove front cap,behind wheel in hub & axle you will find a pin that goes through both,punch out with a punch or type of ice pick. You know something similar in your garage if you don't have a punch. Even a small Phillips screw driver could work. Of course when putting back on reverse procedure, might be able to use same pin if not damaged in process of removing it. Hope this helps, Mike
