The Westwood Powered Chipper-Shredder is driven by the tractor’s PTO & has two separate hoppers – one for soft debris like leaves, weeds & hedge-clippings; the other for branches up to 2.5” (65cm) in diameter. Debris is fed into a chamber containing a set of ultra-sharp hardened steel blades, which shred branches into valuable woodchips; & soft debris into a nutrient-rich material that’s ideal for rapid composting. The Westwood Powered Scarifier fits all S, T & V Series Westwood Tractors built Post Dec. 2000.
