I have had a Wallenstein BX42s direct drive chipper, NO drive belt, NO hydraulic feed, for three months. I have used it quite a lot, maybe 50 hours?
I run it behind my Kubota B3300SU 33 engine hp/ 25 PTO hp with no issues.
This is really basic, but have you inspected the chipper blades? There are four blades on the drum and one stationary blade that is adjustable for chip thickness....my manual recommends 1/32" clearance.
I think it is likely your blades are dull, chipped and or rusty and that is where your chipper stress is coming from. On my current model you only have to remove one bolt and loosen two nuts on the rotor housing to get a good look at the four chipping blades. Another possibility is that the chipping blade to stationary blade gap is too wide.
The four chipper blades have two usable edges. The stationary blade has four cutting corners. If any of the blades do not look really good, see if the other end is better. In a used chipper, all the blade edges could be dull. Your local machine shop should have the equipment to sharpen chipper blades. But if the blades are banged up do not try to sharpen them.....buy new blades and attachment hardware together. You may find the existing blades are not from Wallenstein or for another model of Wallenstein......and the basis of your frustration.
One last thing....chainsaw manuals warn against cutting dirt, because it dulls the chain almost immediately. Nothing in the current Wallenstein manual warns against chipping dirt but I usually cut off roots with dirt clinging to them with my battery powered Sawzall and pile roots for the burn pile. Amputating roots also makes the trunks a straight shot for the chipper. My Wallenstein blades are still on their first edges.
