Another vote for Wallenstein from contented owner of a model BX42. I think this model will run FINE behind your
BX25. And, yes, that 4" X
10" mouth to the
chipper knives is a BIG positive.
The rotor/flywheel on the BX42 weights 110 pounds, the heaviest in 4-5" class. Once the PTO has rotor spinning at 540 RPM the inertia power of the rotor, not the tractor engine, is supplying most of the energy to the four chipping knives bolted to the rotor.
Wallenstein chippers are manufactured by EMB Manufacturing in St. Clements, Ontario, so you likely can purchase cheaper in Canada. PH: (519) 699-9283
I store mine on a dolly in the garage. Lesser implements remain outside under canvas.
I replaced Kubota factory "check chains" with pin-adjustable, rigid, stabilizers from Stabilworks. Stabilworks' mechs make loading implements onto the three point hitch a breeze. Well worth <$200. Stabilworks' mechs also strengthen bracing of lift arms by 50%.

My tractor is a Kubota B3300SU / 33-hp---> 25-hp PTO / 1,800 pounds.
Shoot, I may as well plug excellent MUTS (Canadian built) trailer too. Great for hauling/dumping chips.
