I will try the second link on the chains. Will the rollers reach the ground? I understand about the bar and adjusting front deck height. Rollers are in good shape as the unit only has 77 hours. This is a new to me Prestige. Got into it initially because I was looking for a 4x4 for snowblowing. My old early 90s Broadmoor had the crank to adjust deck height, and it worked great!
