A Great Machine!

I own an ECHO Bear Cat 75311 (SC3342) Chipper/Shredder. (A great machine.) I have owned it for five years. This is a great working & beautifully designed piece of machinery. I change the shredder knives ever couple of years because I shred a lot of leaves for composting every year.

I usually process about 10 - 12 yards of chopped leaves each fall. The 75311 (SC3342) Chipper/Shredder chops them up just great. After rotting down, I end up with 5 - 6 yards of great soil for the garden. All made possible by my ECHO Bear Cat chipper/shredder. Couldn't be without it. It really is one great machine.

The ECHO Bear Cat CH45540 is the perfect match for your compact tractor. It's built with heavy-duty, 7-gauge steel. The 14 x 1 inch thick, 49 pound dynamically-balanced rotor utilizes two reversible heat-treated chipper blades and is driven by a double-banded belt for maximum power transfer. The cantilever mounted rotor design helps reduce wrapping while chipping wet, stringy wood types.

Also available is an optinoal 4.5 x 4.5 inch truckloading discharge chute with deflector cap. This optional chute directs the chips and raises the discharge of chips into the trailer or back of a pickup.

How long will the chipper blades last?
Depending on the type of wood, age and cleanliness, chipper blades will work well for between 5-15 hours. Dry, dirty wood will dull the blades faster. Alternate dry and wet material to extend blade life. Hydraulic feed machines will have longer blade life.

When do I buy a chipper powered by a tractor Power Take Off (PTO) vs. an engine-driven unit?
If you own a tractor a PTO chipper is a smart economic choice.
When should I buy a gravity feed machine?
If you have an infrequent need for a chipper and time is not a factor, a gravity feed machine will fit your needs.
When should I buy a hydraulic feed machine?
If time or efficiency is an issue, a hydraulic feed chipper allows you to be more productive.
When should I chip?
If you don’t plan composting the material, material is green and stringy or larger than 3/4" in diameter.
Will the chipper fit my tractor?
The ECHO Bear Cat chippers and chipper/shredders are designed to fit all Category 1 three-point hitches. Chipper weight and tractor hp needs to be taken into consideration. All Chipper models fit Category 1 Quick Hitch.
