I have a permagreen ultra, i bought it used about 2 weeks ago so i do not know much about them. I do now it does not have the same engine, it has been changed to a 6 3/4hp, not sure if the trans is factory, it is a 5 speed with reverse? can anyone tell me if that is factory? Also i was wondering if you could put handle bar clutch on it, if that is what you call it, to make it easier to shift, since it is hard to shift some times, also make it easier to stop, since you could pull the handle and engage the clutch, to help stop the machine. Anyways any help would be greatly appreciated.
