The Pro XL 21.00 ES is DR's fastest, most powerful wood chipper in the range. Even the biggest hardwood branches won't slow down this Rapid-Feed™ chipper. You simply can't get a more powerful chipper without getting into the hughely expensive industrial realm.
Capable of devouring saplings and branches up to 5.75" in diameter, this machine is designed for the rigours of continuous wood chipping, hour after hour, year after year. The self-feeding action with air-injection venting allows you to simply drop the wood into the chipper hopper without the need to force it through. The extra large hopper opening accepts branches with minimal trimming of side branches. The high discharge chute allows you to discharge wood chips directly into a pickup bed, trailer or wheelbarrow.
The power is provided by a Briggs & Stratton 420cc overhead valve engine with electric start, which produces 21.00 foot pound of torque. The debris management system protects the engine from any stray debris. The commercial-rade centrifugal clutch (similar to those used in well drilling) means there is no load on the engine until it reaches 1600rpm. If you do manage to find a branch touch enough to slow the engine to this rate, the clutch will automatically disengage the engine until it is back up to speed.
The sharp, hard-wearing Pro-Spec chipper knife is made out of high-carbon / high-chromium hardened D2 steel for excellent edge-holding ability. The knife is mounted on a heavy-duty 28.3kg flywheel with a massive 50cm diameter that rotates at 144mph and takes an amazing 40 "bites" per second. Five oversized steel flywheel fins strike chipped material 9600 times per minute, blasting material out of the machine. The inertia created by the flywheel lets the work go smoothly with less strain on your machine.
The chipper is supplied with a hitch pin which enables it to be towed to and from the work area with either a garden tractor or an ATV.
Most impressively, in over 300 hours of testing, DR's testers have never experienced any clogging whatsoever!
