I too have a BX 25 with a BXM 32
Chipper/Shedder with a fair number of trees on 1.5 acres. I think the two pieces of equipment are a good combination and work well together. The only time I've clogged things up is when I put too much small green non-woody stuff through it without alternating with woody branches. With pine or other trees that have wide angle branching, I do wind up doing a fair bit of pushing to get stuff in the
chipper chute, but am happy to do that instead of more cutting. The small ends of branches go through just fine when followed by larger ones..., or you can just pull them out and put them in the shredder as the manual suggests. The shredder is great for smaller things, raked up leaves (but not large amounts), pine cones and such. My one caution, as alluded to by another poster, is putting longer stuff in the shredder. It will grab and snatch things out of your hands! Particularly vines. And I'll echo the advice and your plan to make a dolly for it. Nice to be able to roll it around and get it out of the way! On the newer ones, unlike mine, the feed chute can be easily detached and re-attached in a more space saving position during storage. Nice solid tools. The only thing I've done to mine is sharpen the
chipper blades, adjust the cutting anvil gap (it was delivered out of spec) and greased it.
Enjoy!
I'm happy to answer questions you might have about it and it's use!
