why is the middle blade of my z425 john deere mower cutting lower ?
the deck is a 48 in the blades are new
Not familiar with particular unit, however, often times, the wheels that support the cutting deck have low air pressure. Bad bearings in the wheel or castors can also affect Height-of-cut. Should be something you can see if you take a close look. (Compare all three cutting units)
Good Luck
