The first year we were on the homestead, my wife told me she wanted wood chips for her flower planters, flower beds, and garden.....lots of wood chips. While the chips can be bought by the bag at many local stores, we decided to get something that would allow us to recycle the poplar saplings that love to encroach around the edges of our fields. My nephew has acreage across the rode from us with lots of logging trails that also suffer from the same problem. Since I had a tractor, it made sense to get a 3 point hitch style wood chipper. The only question was which one to get.
After spend numerous evenings browsing through the online forums, I decided to get the Wallenstein BXM32 Chipper-Shredder. The difference between a regular shipper and this particular chipper-shredder is the shredder feature. In hindsignt, I wouldn't get one with a shredder. But I'm getting ahead of myself and will speak more about that later.
The 445 pound BXM32 arrived on a freight truck which unloaded it at the end of my 100 yd long driveway. That is considered curbside service which was fine with me. After signing for it, I grabbed a logging chain and my tractor and secured the BXM32 in the bucket of the front end loader. A few minutes later, it was sitting in my garage ready to be assembled. Yes, it does require minor assembly. The hoppers and discharge chute are bolted to a custom made bracket. Unbolt the items from the bracket, unbolt the bracket from the main body of the shredder, and mount the parts on the shredder.
Here is the BXM32 mounted on my Massey Ferguson 1529 tractor. The diesel tractor is rated at 28+ HP for the engine and 22 HP at the hyrdostatic drive PTO. To spin the 70 pound chipping rotor, Wallenstein suggests 25 to 30 HP for maximum operating capacity. Running the PTO at the intended 540 RPM, I find my tractor does a good job of chipping the poplar when fed as fast as possible. Feeding oak requires a slower pace but it still does a good job of chipping it, just not as fast as the poplar. Since 99% of my processing is with poplar saplings, I feel I have more than enough tractor to efficiently run the chipper.
The chipper rotor is designed with 2 blades to provide uniform chip size. The shredder rotor is equipped with 3 sets of swinging knives (27 in all) to provide a fine mulch. A chop block in the mulcher compartment shreds the material as it moves through the machine. The BXM32 is rated to take up to 1" diameter material in the shredder, which is basically a small scale hammermill. I've never tried putting leaves through the shredder but I imagine it would produce fine mulch.
The BXM32 is equipped with a ledger (stationary) blade that acts as a shear for the moving rotor blades. The ledger blade is designed with 4 usable corners. When the corner facing the rotor blade rounds over, remove the blade and re-install with a different corner facing the rotor blade.
As I mentioned earlier, I chip poplar sapplings for the most part. I use a
6' x 10' trailer to haul the saplings. I have a spot near the wood shed
where I chip. The chipo pile shrinks as the summer progresses. As I
write this article, we are in the middle of spring and I've already chipped
several trailer loads of wood and intend on doing at least one more for this
season. I think I will then have enough for this summer but if not, I'll
go back to the field and continue thinning the saplings from around the edge of
