The dealers told me I can't fix the nipple on the canister wheel on the mower where you grease it and I had to buy a $75 front rim and tire on my Walker!! There were no threads on the nipple and its a pressed versus threaded which people hated. Who sells rims with the canister under $75????????? I went to three dealers one was an Exmark dealer. All this because I bought a cheap Grease gun and it Fuc*** up my nipple. Who sells good grease guns??????
