Question
When I adjust the height on my tractor's cutting knob, the right side of the blade seems to be cutting the ground(dirt) while the left side seems to be cutting where I would like for it to cut.  

Answer
Hi Domingo,

First, check the deck and see if it is level.  Check the guide wheels and see if one side has a bent arm.  If all looks good, you will need to watch the guide/height wheels while you or a helper adjust the height knob.  Look for broken or binding linkage.   

Let me now how you make out.
