We run two walkers currently, we started with a 2000 MDD GHS with the Kubota diesel. loved that machine, and sold it with around 2300hrs. CUrrently we have a 2000 20hp kohler GHS which just rolled 6005 hrs, and runs awesome. Our second machine is a 2008 23hp GHS with over 2k hrs.
Can't beat the cut and finish of a walker.
Thats running a JRCO attachment on the front.
