O.k,--- the "bunny hop" MIGHT be a natural thingy! ---- an example of that would be my Sunstar 20 garden tractors! --- they are a bit hoppy too and they were factory built. --- I think a bit of hop is natural in most but not all hydraulic drives. --- all of the ones I have ever been around run that way.
I have a couple lawnmowers that are really jumpy. one is an old craftsman and one is a yardman (MTD company) both 16hp Kohlers on them and have hydro units made in Indiana under them.
