1)I had a friend with a problem not solved on a 935 for a long time too. I doubt this kind of thing doesn't happen routinely, but that can really piss ya off. You can have to big of a customer dept too.
2)As far as your truck it would handle any of these units. Vermeer is the lightest, Bandit and Morbark is the heaviest.
3)BIG C is right, Morbark has greatly improved on their feed wheels. ( I agree those were terrible.) I have had the luxury of demoing all three units at the same time. It may take an hour of your time to look at it, but like I said before, its what you feel comfortable with. I personally feel confident in these models.
3)I know they are price competitive, I priced them all at this years Expo downtown. Paul is the only guy you should talk to there (on Chipper sales). The key is, is how well the guy you are talking too knows the competition and their own chippers. My guess is some guy answering the phone may have quoted you prices right out of the retail book????
4)Wouldn't get too excited about 15HP difference on the chipper. Wont make a huge difference. BIG C, what kind of engines did you say have a five year warranty? You said a cummins on one. I thought the only one that had a five was a Perkins. Might be a typo. Oh, and is this warranty through the manufacture? So what I mean is, is it a Morbark and Perkins thing or is it a universal thing?
5)I knew the Bandit guy quoted you a Deere!!! He knows no different. BTW-I feel the engine is the last thing you should look at to make a decision on one of these guys, unless its way underpowered. I am saying all of the units make a killer engine. Cummins, Cat, Perkins, or Deere, etc. Cat is the best but most expensive.
6)The weight of the disc helps a lot. Once it gets going its hard to slow it down no matter what HP it is.
7)I think JPS is a BC1000 fan. Where is he? He usually answers everthing.
8)I will see your questions when I get back home. I leave for Missouri first thing tomorrow. (Wife's grandma passed.) Happy you found Arboristsite. I like seeing some home folk every now and then. I think Florida is dominating us. Tell your friends.
9)Let us know how your demos go!!! Plus...for demos try to demo the same wood if possible. Pine is much different than Elm and so on and so on. I know that portion is obvious, but you may not think of doing the same kind of wood. Its like if a company went and chipped a Palm tree in Florida and then did a sumac tree the next day. Its gonna perform much different. You may think in the back of your mind this thing is struggling and not buy it cause of that. They all may struggle with certain woods. So keep an open mind.
