High torque roller?
It seems to me that there are no commercially available 'roller' style chippers. There is only a patent by Max P. Gassman, who I sort of suspect added this section himself in order to create a potential market for his work. Impressively, it seems to have worked, as the 'high-torque roller' is now referenced from dozens of wikipedia-scraping woodchipper review sites. ww 18:09, 3 Feb 2006 (UTC)
Personally, I've never heard of "tree chipper" before. In my experience, "wood chipper" is the more common term. If others agree, then "sometimes wood chipper" should be changed to "or wood chipper". WpZurp 05:31, 18 Nov 2004 (UTC)
I guess the distinction is a usage one. One is an outdoor device used by folks for limbs and branches and such, and the other is anything that produces wood chips. But I agree the distinction in not one the is hard and fast, if anything in language use can be so. I'd be happy with either. ww 22:52, 18 Nov 2004 (UTC)
I am personally offended that people would even consider conflating shredders and woodchippers. Wood chippers are used for wood. Shredders are used for paper, discs, credit cards, drivers licensae. Sensitive documentation!
There is a fundamental difference between chippers and shredders: the chipper uses sharp knives to cut material, the shredder uses blunt objects to provide a tearing action. The consequence of this is that the chipper is sensitive to contamination (soil, metal etc), yet provides a product with a well controlled cut length, whereas the shredder is much less sensitive to contamination but produces a much less well controlled product. The nature of the product is important for subsequent operations, eg feeding into boilers.--220.127.116.11 17:04, 31 December 2006 (UTC)
Major changes and additions
Today I made many changes and additions to this article. I have several notes:
- I agree that it should be moved to "Wood chippers." I too rarely hear the term "tree chipper." Not a big deal, though. There is a redirect.
- I used the word "usually" a lot. Maybe someone can fix taht.
- Someone (probably me) needs to put metric measurements into the article.
- Pictures would be good. I have lots but I'm currently trying to upload them, and having some trouble.

- Looks great. What problems / errors are you seeing when uploading pictures? --Interiot 06:56, 31 December 2005 (UTC)
Does someone know who invented the tree chipper?
I was told it was Mitts & Merrill in Saginaw, Michigan. Can anyone confirm or refute this? I belive it was them, but i think Asplundh Tree Experts improved and made them commercionaly used.
Peter Jensen (Germany) built a chipper in 1884 and produced them for the market. They still produce chippers btw. Ashplund built their first chipper in 1949.. Husqvarna250 (talk) 20:15, 26 May 2011 (UTC)
This article should probably be incorporated into tree chipper and a redirect to the combined article left here. The tree chipper article is larger and better developed and combination in that direction will be easier. ww 18:09, 3 February 2006 (UTC)
- I gave the merge a try, hopefully things aren't too jumbled up. How about shredder (device), could that be merged here? (note that paper shredder has its own article, and I think it should remain separate) If shredder (device) remains separate, maybe it could be renamed industrial shredder or something, though again, the distinction seems to be more of scale and use. --Interiot 22:13, 22 September 2006 (UTC)
- Well, I have a chipper/shredder with two different mechanisms and two different hoppers. (See here ]) The chipper takes branches up to 2 inches (5 cm) and turns them into wood chips using rotating knives, while the shredder deals with softer plant material with rotating steel flails. I think they are different animals and probably should have different articles. Luigizanasi 17:40, 28 September 2006 (UTC)
- I think that shredder (device) should stay separate. There are many metal shredding machines that are entirely different from wood chippers. In fact, most wood chippers don't shred at all. They cut or shear. Also, in the industry, the term "tree chipper" is usually only used for very large capacity wood chippers, in which case the entire phrase is "whole tree chipper." I believe the current title is accurate. Maxwahrhaftig 23:56, 9 November 2006 (UTC)
"Although this was the first digital feed control for this type of machinery, the net result was sawdust."
It could be the lack of sleep but this doesn't seem to make sense. If the sentence is implying that the new controls allow such fine precision that the wood is chipped into sawdust, this should be made clearer. I'm still finding my way around wiki but it appears, by inspection of the history page, that this is not a vandalism. The sentence in question along with alot of other material was appended in this change:
