I use a 48" Viking and a 36" Metro HP and the problem I am having is probably a simple fix but I've tried everything I can think of. The problem I'm having is while turning to the left or right, more evident on right turns is the mowers are leaving almost divet like marks on some of our lawns. Iv'e tried making one extra pass around properties before I begin to do the straight passes so I'm not turning so sharp and have tried slowing down when turning etc and nothing seems to be working. My Viking is older but runs like new and my Metro is brand new this year (only used it 2 times on my yard). Any thoughts?
