I have 06' Cub Cadet Tank M54 with the command cut system deck that leaves an uncut strip of grass I believe is coming from the left side. I use the standard high lift marbane blades that came with the mower. I have 2 sets and both sets leave the same streak. The deck is level and I run a very shallow 16th pitch from front to rear with the front being lower. The front tire pressure is set at 14 psi and the rear at 10psi. I have spent hours upon hours trying different pitch adjustments and level checks and cutting heights and nothing seems to work. The only way I can get a remotely acceptable cut I have to cut at 1.5". I really enjoy this mower and is very comfortable to operate but this problem has stumped me. With all the positive feedback on the command cut system it must be me. Please Help. I cut mainly Bermuda grass with the occasional centipede property. Also cut a neighbors variety of grasses yard.
