The only mod I've done so far was to the ROPS. It is so ridiculously high on this little machine that it's an absolute hazard on my property and impossible to get into the garage. The ROPS easily flips flat to the rear, by pulling two pins and removing the yellow triangle. I took a step further and put it in remote storage mode for now. Even the vertical supports with the light pods are well over 5ft high.
The auto throttle is pretty neat. The further you push the go pedals, the higher the engine revs, like a piece of commercial/construction equipment. The last CUT/loader I put any time on was a mid 80's Kubota 4x4 manual transmission. I was a kid working in a horse farm then.
