The AL-KO Silent Power SP5000 Shredder has an ingenious design that “pulls” material matter through, squashing and cutting it silently and safely. If you live in a built-up area, this quiet machine is ideal. Automatic kickback-free feeder mechanism with shredder roller made in hardened steel crushes branches for accelerated composting. Automatic shutdown when branches are jammed due to anti-locking mechanism. Reverse rotation to remove jammed material. Sturdy undercarriage with large wheels for enhanced stability and easy transport. As the material is crushed, the surface area is inceased, giving micro-organisms plenty to feed on and accelerating the decomposition process.
