Fitted a Birdseye Wagway tree shredder disc to a PC220-5, and made it work with two V60? Flow divider valves on the pump outputs, to achieve the 35-60gpm required to run.
Boss insisted on the flow being on the high side, so 60gpm it is (I did a switch for 1pump, 2 pump anyways). Placed a 1" opening screen guard on the cab, and tested it for operation.
Job foreman comes down to operate it. First pass, he sends a football sized chunk of tree past me @ over 60yards away. I'm done. It works.
Several weeks pass and the assigned operator, having finished felling trees, decides to shred a brush pile the dozer created. Not heeding the instructions of never see the teeth while in operation, he dips the disc down and finds a wrought iron fence within. Two pieces launch toward the cab, with one striking the cab side boom cylinder barrel, leaving a 3/8" deep gouge on its way to ricocheting through the cab side window and out the entry door. The second piece fit perfectly through the 1" mesh guard, the tempered front window, grazed the hair off the operator's head, and left a 1/2" hole in the rear cab sheetmetal top radius. Somewhere out there is a PC220-5 with a work lamp mounted on top rear of the cab.
Bought a $1300 piece of 4'x5'x1-1/4" bullet resistant lean and fitted it to front of the cab, yet, no one would elect to continue operating it.
Sold the attachment at auction. The contractor who bought it never did pay us for the lexan, which was not part of the auction.
