Chipper pto driven wood chippers

[5030]

I do a lot of chipping of Poplar/Aspen tops and there are a lot of twisted limbs that are a pain to cut and them pick up to feed individually, so I wanted the largest opening I could get, that is one of the reasons I went with the MX9900. The roll feeder does a good job of bending, breaking and folding the limbs in. So thus far I haven't seen and issue with the single feed roller. I feel that if the roller teeth are sharp it should work well.

Interestingly, so does my Jinma (bend. twist and break) limbs on the infeed. I did pull the roller when I first bought it and dressed every cross bar to a sharp bevel with a hand grinder, then I relieve some spring tension so the infeed roller grabs well. It sucks everything in except maybe a large fork so I keep my Silky hand saw hanging on the dise of the chipper just in case...it's a rare case btw. The opening on the Jinma is actually 8.5" each way. Must be the Chinese 8" is an American 8.5.....:laughing:

I have a bush hog brand (rebranded goossen) with a big hopper feeding a hammer shredder for branches under 1.25" and a chipper chute for 5" stuff. I love the shredder. Most of what I chip is small stuff. it's fast. Nice chipper and like most mechanical feed ones, as long as the blades are sharp it pulls in fast enough.

The Woodmaxx 86 H has been chipping my burr oak branches. While larger branches are usually for firewood I do occasionally chip 6 inch log using a bx 2200 Kubota. The reason to go with the hydraulic feed is to regulate the speed of the chipping, important for a small tractor. This setup is working very well. Just changed blades this past weekend which is also important as sharp blades require less hp.

how much time does it take to change out a set of blades on the Woodmaxx for example?
I keep my mower blades very sharp; would do the same here but are they hard to get to?

no vertical hoppers for me.

I don't understand how a manual feed model can have a regulated 50ft per min feed rate.

Yes, the hydraulic feed control is great. I have my MX9900 on a 55HP(engine) 45HP(PTO) and I don't see a drop in RPM unless I feed a hard wood limb 7 inches of more into it, that isn't very often because anything that large is firewood. But when the occasion does arise I just slow the feed.

Another good thing about the feeder speed control is you can manage the size of the chips you want to some degree. We use a lot of chips for compost and in most cases the smaller the better, so I just slow the feeder and I can produce really fine chip/shavings. My high bush blueberry plans love the nice fine pine wood and needle shavings.

The Woodmaxx 86h, 4 flywheel knives are easy to change, one bolt with an 18 mm nut is removed to open the hinged clamshell housing. Each knife is held by four, 6 mm Allen bolts and a 17 mm lock nut.

It takes about 30 minutes to change out 4 blades and retorque them to 40 lbs.

The bed knife is trickier, but easier after you've done it once. It requires the removal of three 6mm Allen
bolts. To assist, use a long Allen 6mm wrench with a 25 degree taper end to fit into the narrow space from flywheel to housing. To achieve the 0.03 inch gap, a fold in half the stiff card board back from a yellow legal pad and use it as a jig to get the 0.03 gap between flywheel knife and bed knife. Torque bolts to 40 lbs.

Make sure to Air gun debris out of Allen bolt heads.

The bed knife takes about 30 min or less once you know the technique.

Tools needed:
Torque wrench
17 and 18 mm 1/2 inch sockets
18 mm wrench
6 mm long Allen, 25 degree taper helps
Leather gloves for sharp blade handling.
Use the fly wheel safety locking pin included with the machine

thanks, very helpful. All makes sense.

Why not?

As expired (or an unwanted credit card works just a s well).... and it's easier to deal with.

I sharpen chipper blades for all the tree services around here....and my own too. I do long ones and short ones.
