Thanks for the suggestions. I did take a look at them.
I decided to go with the Mackissic TPH122 which is the smaller of that company's 2 pto model
chipper shredders. Its rated at a minimum of 10HP but as I found out in the shopping process, when you buy a PTO
chipper, you need to be sure you use the right HP rating for your tractor in making your buy decision. I was told that its the HP at the "yoke" that counts...not the engine HP. The JD 2210 has a 23 HP engine but is apparently rated at 17.7 HP at the yoke (which I take it is the HP at the point you connect the
chipper to your PTO). Anyway, the next biggest Mackissic unit (TPH183) was rated at 16 to 50 HP. And while I have 17.5 HP available at the PTO, it was suggested to me that the "recovery" time (I.e., the time it takes for the
chipper's fly wheel to get back to full speed after handling larger branches) will lag noticeably with only 1.5 HP above the bare minimum needed to operate the machine. That could get frustrating when undertaking larger jobs.
So, I downsized to the smaller model since I figured its 3.5 inch rated capacity was enough for most of what I will need to do anyway and the smaller unit was about $1000 cheaper to boot.
By the way, I also was told in this process that Mackissic makes the DR line of chippers that DR Power Equipment sells. I think MacKissic's own brand though is more machine for the money.
I also looked at the Chinese chippers available here now and as you might expect, they seem like alot of machine for the money. But I'm still not ready to seriously consider buying Chinese made tractors or implements until they become more mainstream in the U.S. and I can get comfortable with product quality, parts availability, warranty policies and practices, etc.
Thanks Again though for taking the time to add to my options!
