Liberty Professional 8" (540 RPM) PTO Chipper. As a pro, you'll be handling larger volumes of debris more frequently, so this unit comes with an automatic feed roller system. That means you don't have to stand around and feed the branches in one at a time; the grapple teeth and rollers draw the branches into the chipper while you're getting the next batch ready.
Liberty Ranch 8" (540 RPM) PTO Chipper. This unit is meant for larger tractors: 18 HP and up. It takes on larger branches than the 5" model (up to 8 inches in diameter- small logs, actually); so it needs the extra power to spin the 106 pound flywheel. As you clear land or log-off trees, there's a lot of branches, leaves, and chunks left behind. This unit will make short work of that bulky stuff, and turn it into useful mulch for soil improvement and landscaping.
Liberty Ranch 5" (540 RPM) PTO Chipper. These brawny units are meant to use your tractor's power to help you clear brush, limbs and debris. You feed in branches up to 5 inches in diameter through the generously sized feed chute, and useful mulch comes out the discharge chute- it's that simple.
PowerTek (7") 31HP Hydro-Feed Tow-Behind Chipper Shredder. The 31 HP Briggs & Stratton Vanguard engine dependably drives the operation of a 30-inch flywheel-and-knife combination that chews through wood up to 7 inches in diameter. This allows you to turn wood too small to be firewood into valuable mulch instead of burning it on-site: better for your budget, and the environment.
PowerTek (7") 28HP Hydro-Feed Tow-Behind Chipper Shredder. This is a terrific tool for small-to-medium landscape maintenance businesses, or folks with a lot of property to keep tidy.

The 360° rotating discharge chute is a nice touch, too. It allows you to feed the chips into a cart or truck; or create a tidy pile.
Troy-Bilt (3") 250cc 1150 Series Tow-Behind Chipper Shredder. It can handle branches up to 3 inches thick. An inch may not seem like a lot, but try breaking a 2" branch over your knee.

The engine is larger, and the chutes are more generously sized so you fight less to get cumbersome branches and debris safely into the hopper.
