I have a Woods 5000
chipper/shredder which I've owned for about 7 or 8 years.
If the OP is a typical residential user (like I am), I think he'll find the shredder gets as much or more use then the
chipper.
I've ran this behind:
Deere 790 (24 PTO HP)
Deere 4400 (30 PTO HP)
Deere 4520 (40 PTO HP claimed...46 PTO HP as tested)
(All PTO Data from TractorData.com)
All three tractors ran the
chipper quite well...an occasional bog on the 790, but pretty good for the most part.
Fordlightning, the OP, has a Massey Ferguson 1529. Per Tractor Data, the 1529 has 23 PTO HP.
I think the Woods 5000 (rated at 15-40 PTO HP) would do quite well....maybe an occasional bogging.
Jeff9366 wrote the hard work involved in chipping. I won't deny it's strenuous, but unless one is working 8 hours straight, it's not really too bad. I'm 66 (closer to 67) and in reasonably decent shape considering the stroke and heart attack). I'll chip/shred for a while, take a break, then chip and shred some more. It'll get done, but it doesn't have to get done that quickly.
Chippers are dangerous, as are tractors. no kids, pets and no alcohol while working...drink water and look forward to that beer when you're done. I'd also recommend a Forester's Helmet with hearing protection and a face shield.
The video is not my unit...just got it off YouTube. Like the unit in the video, mine doesn't have a chute. A chute is an option, but since I bought my 5000 used (Craigslist) ad it gets worked 3-4 times a year, I don't want to spend another grand on a chute.
I just noticed that Fordlightning has GC1720 (must have traded his 1529) with (per TractorData) just under 20 PTO HP. I still think the Woods unit would work, but running 5" stuff might bog the tractor down.
