Hello guys and thanks for the site great info. I moved and needed a lawn tractor and I was blessed to get a Cub model 1000 built in 75 with a 44 A mower deck. I down loaded the manual for it but I need help. I tried to adjust the deck but the roller on the front keeps digging into the ground even tho I set the ecentric on the side to keep the deck at the highest level?? What am I doing wrong.
