Hey,
I have a Deere 3320 ( 25 PTO hp ) and a Patu (Finnish) 4" disc type chipper, bought it about 5 years old with few hours. Wanted a Valby but too much money for me. I shred the trimmings, fallen tree limbs, etc- almost any thing that fits will chip no problem. I have stalled it but it has to be something relly hard, hard to predict, but its rare.
A couple of observations- first,it is a disk type chipper and is very safe, manually fed, the machine gently pulls the material in, and you can pull it out. Deep chute so you would be hard to get sucked in. No " chuck and duck" here. The other thing I like about the Valby and Patu, is the low flat(level) feed chute, so you do not have to lift it and slide it down a sloping chute, which is totally unnessary with mine. If I have a long branch that will fit, put in the but and walk way to get the next, it feeds itself in a controlled way.
I wish I had a 6" machine, just so I could do less clipping to get the crotches in, but another 5 or 10 hp might be needed.. Anyway totally worth it.
One more thing, the blades. Do not even think of using your grinder to sharpen them, the precise angle is critical and they must be ground wet. I sent my set of 3 to Tennessee Saw and Knife with the mfr's specified angle,
got em back in a week, and having run 2- 16" diam whole white pines and orchard prunings through, stikk look and feel like new. The replacement TTT blades are $90 a pop, but they are good for 45 sharpenings. When I took them out, they still looked good, but the guy I bought it from had never and them sharpened in 5 tears!
Good luck and work safe. I like my wood cutters helmet with face shield and ear muffs. You will need them.
