I have some great looking lawns which cut smooth and leave beautiful stripes. But hiding underneath the premium turf is a nightmare of bumps that you don't know exsist until you're riding over them with your mower. I get thrown all over the place! I have started to feel some extra stress in my neck and back from the bouncing turbulence. This week I'm going to get a suspension seat for my lazer, but I'm not sure how well it's going to solve my problem. Anyone else have lawns which are so bumpy you have to mow them extra slow? Any solutions?
