How does a PTO chipper do on a sub compact tractor

4" PTO 3 point wood chipper running on a sub compact LS MT122 The tractor has a 22 HP diesel engine with about 18 hp at the PTO shaft

Very nice. I just picked up that tractor and have yet to get any PTO attachments. Nice to know it can handle them.

I'm sure if you wanted to chip 6" or bigger, then you may need more HP at the PTO. I personally think anything over 4" can be firewood. If you get a hydraulic feed chipper that is driven from the tractor then you may need a bigger tractor. Those rob some serious HP.

Does it bog down the engine when you first engage the pto? Are does the belts slip till it catches up?
