I inherited a 44" Broadmoor rider from the last guy that had my job and I noticed the roller bar on the deck is hitting the ground on the left side when in the up position. Is this a simple adjustment of the leveling nut or could it be some other problem. Don't you usually do the leveling with the deck down? Seems to mow level when in the down position. Any ideas before I try to level it and screw it all up. Thanks Don
