I just got an old toro zmaster it has about 1300 hours on it. 1. The deck height adjust is extremely hard to pull up and out of the transport position (the highest height) how do i fix this? (Deck seized?) 2. The deck is uneven, how do i fix this? (Deck Seized?) 3. I have a small grease gun, but it won't grease these fittings, its just comes out the sides of the fittings, not into the fittings. 4.the deck also has alot of wear and tear, like their is no anti-scalp wheels, and the deck mounts for them are bent pretty bad, anything i can do to fix this? thanks for the help in advance!
