You do realize it is a governed engine. You can safely run it under load for extended periods of time at up to belt pulley speed. I believe that is up there around 1800 rpm.. as pto is around 1500 or so.
As for the shot lift.. sounds like it may just need some tlc. A new top gasket, bottom gasket, pto flange gasket, side cover gaskets, lift piston, piston oring and backup washer, relief valve, and halves gaskets run less than 90$ with shipping. That assumes your lift cyl isn't scored too deeply and can be honed. if it can't.. double that to 180. Also assumes that pump chambers aren't cracked and that plungers are ok. ( Most of the time they are ).
Anyway.. that 'standard' 90$ service takes about 8-9 hours using only a couple different size wrenches and a torque wrench, and cleaning supplies.
Also.. if the lift is a tad weak on the thin UTF fluid, use the oem spec 90wt gl-1 or gl-3 oils available at napa or TSC, or even a penzoil 80w90 gearplus gl-4 yellow metal safe type oil. Castrol makes a YMS oil as well.
It's not a bad job... a non-mechanic can do it via 'cookbook' with an I&T fo4 manual in hand and a bag of oil dry and paper towles /forums/images/graemlins/grin.gif

That's what ballast is for.. wet tires, rim weights, front suitcase weights, frame weights.. etc.
