Grinders, chippers and shredders
By Lauren Heartsill
The Diamond Z DZH4000tkt grinder, DZ’s smallest horizontal model, can process up to 95 tons, or 620 yards, of pallets and construction waste per hour.

Here are some questions to ask to narrow your brush chipper search:
What size chipper do I need?
For tree trimming, use a small brush chipper. If you are performing land-clearing work involving tree takedowns, you will generally use a larger chipper. Choose a chipper that can handle at least 80 to 90 percent of the tree and brush you need to chip.
Where do I put the leftovers?
You can partner with a company that needs wood chips, sell the debris to a mulch business or recycle the chips as mulch, compost or an alternative source of energy. You also can check with your local waste authorities because many cover composting in their services.
Which cutting mechanism should I use?
Drum chippers are designed to cover wide feed openings and large material. They are easier on expensive cutter bearings and typically perform better when chipping materials with string fronds, like palm trees, according to Vermeer. Disc chippers can handle materials of all sizes and are more operator-friendly, although they weigh more than the drum chippers.
