Gazz As others said don't get in it's way,if your not on level ground linkage can bind,or if load comes out uneven can bind. Be careful leaving it overnite if oil leaks out bed can fall and severely bend your frame, just take your time and study it you''ll figure it out. Most systems have a metering orifice so the bed can't come down too fast,sometimes when spreading you need to let it down some so you can start again in another place. A skilled spreader man NEVER scoops !! LOL
