Whew!! You must be super strong to be able to lug 10" trees up to and load in the chute of the
chipper. I have a Wallenstein BX62S that will handle 6" trees and believe me that's all I can handle too. I cut and chip 750-900 small pine trees every spring to maintain my forests. Dragging a 6" freshly cut pine that's 30 feet long is all this old man can do.
After I cut the trees, I do use the grapple to "bundle" them. Then I go from bundle to bundle chipping them.
I chip the trees "in the round" - IE... I don't remove any limbs.
I was going to get the next size bigger
chipper - 8" or 9" - but the dealer said - go out and cut a 9" pine and see how far you can drag it before you decide.
That's why I got the 6" model. And since I don't clear cut these small pines - I have to at least drag them to where I can get at them with the grapple.
I've never had a moments problem with Wallenstein chippers........and as motownbrown indicates it really a two person operation. Actually, three would be nice - two to do the lugging/chipping and I could easily supervise. Whatever the case - the cutting, bunching, lugging & chipping is a real task for me in the spring.
