There was a semi recent thread on PTO chippers. I read through that. My main question is on power feed vs gravity feed. I have only ever used power feed. My uncle has one for his 30hp ford and I have used it quite a bit. I don't recall who made it. He has had it for along time, probably 25 years. Anyway, I have a NH TC-45 and looking for a
chipper just for stuff around the homestead, I probably wont even use it that much really. I do like to clean up If I scavange or take down a tree in my woods, but I would take everything 4" and over for firewood. IT seems you can get basic non power feed ones for around $1500. What are they like to feed? Do they vibratron the crap out of you as you feed it? Is it a lot of work to feed or does stuff kinda naturally self feed? Another grand gets a power feed woodmax, which everyone seems to be reasonably happy with. Just trying to decide if I should cheap out and save that grand.

In choosing, I believe you first need to asses what you're going to chip and/or shred. Once you have that you can choose your weapon. Some fall lots of 6" trees 30' tall and feed it into a
chipper whole, others are general purpose clean-up chores (like myself).
I have property that constantly sheds limbs from tall hickory and walnut trees plus a few grand oaks, so it's a ritual to run the property and collect the debris, usually to a central location, periodically. Then, once or twice a year I'll attack the pile with my PTO
chipper/shredder (it's 3.5"
chipper) that is gravity feed. It's got 2 chutes, one above the other, the lower is the
chipper, the upper is the shredder. Yes, I find keeping a pair of lopping shears close by is necessary, as it won't take a "Y" branch, but most of mine will separate easily by standing vertically crotch down and wishbone splitting them, hey they fell to the ground for a reason so they split fairly easy. The brushy stuff I cut up to an inch easily feeds in the shredder, bigger butt first in the
chipper. Now, here's where I've found mine to be advantageous - every fall I have to vacuum leaves from around the property - that unit will reduce volume somewhat, but primarily I just collect the leaves reduced to about 1.5" pieces after reduction into the trailer, then pull it to the shredder and use a snow shovel to transfer from the trailer to the shredder hopper, it reduces it all to about 1/4" pieces that I pile for compost. All the leaves get mixed into the chips from the branches, and in a year I've a pile of garden gold. Anything larger than about 3" gets stacked for firewood use by a BIL or friends.
So, just trying to share some real world experiences with smaller tools, I simply don't need a 6" or 9"
chipper, nor power feed, but I used a portable homeowner unit for years (maybe 3 different ones for over 40 years) and simply outgrew them, but not by much.
Here's a pic of what I'm currently using:

I can attest that even though it's a import, it's fully capable of what it's designed for, I run it on my MF GC1720 and have never herd the tractor labor, never have had a belt issue (some claim they chew up belts), but I grease it every use and store in my container, so it's not abused. I've got about 30 hours run on it in one year, had a large accumulation, and it's done all I've asked of it. For the price it's sold for, I can honestly recommend it, and BestCo treated me right on the purchase. YMMV
