Hello - Just moved to 2.5 acres and am a first time zero turn owner/user. The Husq MZ52 manual is really bad. Having difficulty understanding how to balance the deck. Thought I had it; cut the grass; then found out that somewhere along the way the deck settings loosened and dropped. Not understanding how to properly adjust the set bolts and how they and the chain links work together. Once I set the measurements, one adjustment bolt is loose while the other is tight. Same with the chain links; one diagonal set is tight/taunt while the other diagonal is loose. How do I make sure my measurements (front to back and side to side) are locked in? Thanks so much! - David
