I have a new b3200 tractor with a mmm RCK60 - 27ba and it does not mow level. I have checked my set up and all the guide wheels are set correctly. The mower seem to mow lower on the right side. I have checked the lift linkages and all appear to be adjusted properly as far as the measurements go but I think the link measurements are for the lifting of the deck not the levelness of the deck. The deck when lowered rests on the wheels and not on the linkages. I love the tractor and the mower does mow well. My yard is not flat but has a gradual grade to it but no matter which way I mow it appears that its mowing unlevel. The tires on the mower are solid and not pneumatic..tractor tires are inflated properly too. The front of the blades are lower than the back but I think that is normal...any suggestions would be appreciated...I love the tractor and have had the timing adjusted to eliminate some of the vibration...not all but its much better after having the timing adjusted....I will recheck the length of the front and rear links but I dont think that will matter since the deck rides on its wheels.
