Masport Bio-Wizz 6.5

The Bio-Wizz enables users to shred and chip with just one machine, without changing or adapting parts. What's more, if there are two operators, you can chip and shred at the same time.

The main chute is the shredder chute, which leads down to nine metal flails. The funnel on the right is the chipper infeed and has a flywheel-mounted chipper blade at the base. This is a versatile piece of kit and is well built, but the testers find a problem with the height of the shredder hopper. Matters aren’t helped by the fact that the exhaust comes straight out on to the operator’s knees and upper legs. Even one of our testers, standing well over six feet tall, has difficulty loading this part comfortably. “It’s awkward having to lift the material that high and then gently lower it into the shredding mechanism,” he says.
But the testers love the chipper on the Bio-Wizz. “It works very well and easily slices through material of 75mm or even 85mm. It cuts like a scalpel,” says one. “The only limitation is that the wood must be straight — if it has a bend, it won’t pass through the narrow, tapered part of the chute.”
Pushing the Bio-Wizz to its limits, one tester feeds the shredder and another operates the chipper. Yes, there is the occasional struggle but this is a powerful machine and the engine quickly finds its revs. It continues to cut consistently.
Chips and shreds exit from the same port. The testers are impressed with the fineness of the material. “This should break down really quickly,” says one.
With the chipper unit jutting out from the side of the machine, transporting this unit is likely to be more awkward than with dedicated shredders unless the chipper funnel is removed.
The wheels are small and have hard, rubber tyres. The testers find manoeuvring the unit around site is also difficult because the frame is “back-heavy” with the weight of the engine. Access to the blades requires a spanner.
