I'm assuming the weight on the downslope was turning the engine crank via the HST, and overcoming the compression one piston at a time. It was weird to watch, moved about half an inch each time it happened.
I jumped back on and set the parking brake, which I will remember to use all the time now. Lesson learned.
You assumed wrong!!! you don't run a hydro backwards!!!! To get more technical the rear wheels can do nothing and the only time a hydro works is with a pump running!
You transmission as it gets more hours on it very well will leak down sooner and allow the tractor to roll easier then it does now when shut off!!!!!
