I knew their had to be a better way, Thanks for the info. We are going to fix it this time like always but change to your idea this winter. BTW called the JD dealer a little farther off and they said their was an update bulliten some time back that you put an extra big special washer behind the gearbox to help the seal keep out the crap. Also he suggested putting on a hose as the other kind gentleman posted here. That would make a lot of difference cause I'm not 8 feet tall and very hard to reach that zerk.
More grease is better.
The service manager said that the washer was not even listed in the parts section but they stocked them anyway. Hope this helps somebody else with similiar problems.
