I own a Kubota G1900 Garden Tractor with a 60" deck. This deck cuts very nicely but it tends to bounce alot while mowing due to being a Floating type mower. There are caster wheels on the back and anti scalp wheels on the front. Will the bouncing wear out the mowerdeck driveshaft or is this the way it is designed to operate? I had a suspended mower on my last tractor, could someone explain further. Thanks
