I assumed this mower cut grass at height of 4.5" as it states on the deck. I cannot get the mower to cut any higher than 3.5". The deck is level, tire pressure is as stated in the owners manual. I contacted the dealership where I bought the mower. They explained a customer had just brought in a mower with the same problem, however, that mower did not have a foot assist to raise and lower the deck and my mower has a foot assist. I do not think the foot assist has anything to do with this problem. There is a plate that connects the hand lever that raises/lowers the deck to the carriage attached to the deck and another plate that connects the foot assist to the hand lever plate. My mower did not have the two bolts connecting the hand lever but had the two bolts that connected the foot assist which the end of the hand lever rested between those bolts. I bought the two bolts for the hand lever plate and assembled as described in the parts diagram but the mower will still not go higher than 3.5". Anyone with this problem?
