I've been using a Valby pto chipper for about 25 years, works great but wanted to get a chipper with powered rollers. I'm primarily using the chipper for branch trimming from black walnut, and have had to do quite a bit of side branch trimming to get the larger (3 to 4 inch diameter) to feed . Looked at the sites for several brands, found most of them were "currently out of stock". Would have preferred a USA made unit, but ended up going with Nova Tractor's BX102. I've had several issues with the mill, to start with one of the knobs to hold the input chute in position was missing, probably because the holes in the input chute didn't line up, preventing the guy assembling the unit at the factory from installing it. The distributor did provide a replacement, had to wait for it to come from China. The big issue however is that, especially when chipping smaller branches, especially those from spruce or cedar, there is significant accumulation of debris building up in the chipping chamber, wrapping around the flywheel's axle and between flywheel and sides of chamber. Contacted distributor, was directed to 1) adjust blade-to-anvil clearance to 2 to 3 mm max, and 2) run the chipper at higher rpm. I found that adjusting the blade clearance was a problem, as there's about 4 mm variance from one blade to another, so have to have clearance of 5 mm to prevent the blade with the minimum clearance from striking the anvil. Distributor said that variance of 5 mm or less "is acceptable". The chipper is sold as being used with either 540 or 1000 rpm, comes with a 540 6-spline connector. My tractor has only a 540 rpm pto. Distributor says that they've had issues with pine or cedar "stucking" the unit, that chipping "real wood" will help to clear the unit. When the unit gets crammed with debris, it takes over half an hour to get it cleared out using a variety of tools to pull out the debris, after first waiting for the flywheel to cool down from its rubbing against the debris. I've come to regret by choice to purchase this unit.

Jinma wood chipper has the same issues. I added a plate to the infeed to deflect the brush/limbs toward the outside away from the axle but wrapping around the axle was still an issue with Cedar! You have to vary the wood as the manufacturer states and that doesn't eliminate the clogging. Not the chippers fault! I have an old drum chipper that didn't have that issue.

Edit: old thread that got bumped.

Is this it? https://novatractor.com/BX102-wood-chipper

400 and something pound flywheel for $4400 delivered? That is amazing compared to Echo, Pequea, Salsco. The Woodmax is likely the out of stock one you mention. This one shows out of stock.

Why not loosen the blade that sticks out the farthest and shim the rear of it? Some of these chippers use blades that are half the length lessening the point loads and perhaps more air paddle per bite.

I looked at the vertical offset of the top pin to the lower pins and it is 24 inches for cat 2. I believe this is the case for certain parts of the world but it is 19" for Cat 2 here in the USA. I guess it will pick up the rear of it real good. Any idea about this aspect? Logging winches seem to have the top pin real high on the implement for some reason.

Interesting chip wagon there in the video has the pto shaft extended to the rear and remote 3 point hitch. Where can one get one of those?
