SC3305 3 Inch Chipper/Shredder

Solid, welded construction, strong motor mounts, large loading hoppers and large chipper chutes are some of the features you'll come to appreciate with this line of chipper/shredders.


Two reversible chipping blades and twelve reversible flails are the most efficient method of reducing debris.


Add an optional blower so you can direct the flow of chips and debris into your pickup box or a trailer.

The serrated flails are the best in the industry. Bear Cat shredders use a staggered flail pattern to give better performance when reducing tough and fibrous materials.

WHY DO THESE MACHINES HAVE 2 OPENINGS TO FEED MATERIAL INTO?

Because these machines are Chipper/Shredders. This means that you put foliage down the large top chute to shred it, while branches are inserted into the lower front chute to be chipped.

 

WHAT SIZE BRANCHES CAN THIS BEAR CAT CHIPPER/SHREDDER PROCESS?

This Bear Cat Chipper/Shredder can process branches up to 3” (75mm) through the lower chipper chute, and foliage and general green waste up to ¾” (19mm) down through the top shredder chute.

 

WHAT IS THE DIFFERENCE BETWEEN A CHIPPER AND A CHIPPER/SHREDDER?

A Chipper is a spinning, thick metal disc that has two or more blades attached to it. It is designed for fast and efficient processing of branches. A Chipper/Shredder has a chipping disc for fast and efficient processing of branches and wood. In addition to this, behind the chipper disc it also has spinning flails or hammers. This is the shredding chamber which is designed for faster processing of small branches and green waste.

 

HOW DOES A CHIPPER WORK VS. A SHREDDER?

A Chipper works by passing the material between a rotating blade and an anvil. The anvil is the edge that the blade cuts against with a gap of approx. 3mm between them. With a Shredder you have multiple knives that are not fixed but swinging. The material drops into these flails and is shredded almost instantly to a size where it is small enough to get out of the holes in the discharge screen.

 

WHAT ARE THE ADVANTAGES OF A CHIPPER/SHREDDER VS. A CHIPPER?

- Easier and faster processing of small branches and green waste (hedge clippings, general garden waste such as old plants, leaves etc), as well as processing all the larger branches and wood materials that a chipper can process. This makes it a more versatile machine that is faster to use.

 

- Longer Blade life. As a chipper blade and anvil are fixed surfaces with only a gap of approx. 3mm between them, if a stone accidently goes into the chipper it will damage the blades. With a Shredder you have multiple knives that are not fixed but can swing. This means that if a stone accidentally falls into the shredder, the knife knocks back out of the way and in most cases no damage will occur making the blades and the knives last longer.

 

- Better composting material. Professionals agree that shredded material is better because it has a wider size range of material coming out of the machine. The theory behind it is that some particles come out very fine which break down into the soil fast but there is enough larger material mixed with the fine material to retain the moisture around the plant roots. With a chipper only, you get a more uniform size material that takes longer to compost or break down.

 

- More versatile. Shredders have been used to process a wide range of materials including animal feeds, seaweeds, soils, grasses, shells, fish etc. (Please note that although the machines can process a wide range of materials, they are designed for processing green waste so ask your local dealer about what effect your unique application could have on the warranty).

 

HOW LONG DO THE SHREDDING KNIVES LAST?

This will vary depending on how the machine is treated but in a normal residential application they will last for many years. The knives are also reversible so if one side gets worn you can turn them over.

 

HOW LONG DO THE CHIPPING BLADES LAST FOR?

The Chipping Blades generally stay sharp for between 5-15 hours of chipping. When chipping softer green woods the blades will last much longer than when chipping harder woods like bamboo and tea tree. Once the blades have lost their sharpness you then turn them to give you another sharp side. Once both sides are blunt you can sharpen the blades. These blades are able to be sharpened many times and last most domestic users for a number of years.

 

CAN I CHANGE WHAT SIZE MATERIAL COMES OUT OF THE CHIPPER/SHREDDER?

Yes. With the 3” Bear Cat Chipper/Shredders you have 4 different screen options that you can purchase to alter the size of the shredded material. The screens with the larger holes are used for shredding wet pulpy materials and screens with smaller holes are mostly used for specialist applications. The screen that comes standard with these machines has one and a half inch diameter holes and suits 99% of NZ gardeners.

 

WHAT IS THE DIFFERENCE BETWEEN BELT DRIVE AND DIRECT DRIVE AND WHY IS BELT DRIVE AN ADVANTAGE?

With a Direct Drive machine the disc assembly is bolted directly onto the engine shaft. The disadvantage of this is if a bit of steel or some other hard object gets into the machine, you will most likely break the engine shaft requiring replacement of the engine. With a belt drive machine the Chipper/Shredder disc assembly is driven by a belt that runs between the engine and the disc. This means if something too hard goes into the machine it can simply slip the belt and not damage the engine.

 

WHAT IS THE DIFFERENCE BETWEEN A BEAR CAT CHIPPER/SHREDDER VS. OTHER CHIPPER/SHREDDERS ON THE NZ MARKET?

Bear Cat Chipper/Shredders are made in the USA whereas nearly all other Chipper/Shredders available in NZ are made in China to cut cost. This generally means lower quality bearings, belts, blades, knives and a lighter construction. Most also have a molded plastic chute vs. the thick steel used in the Bear Cat chute construction. Another major difference is in the performance of our cutting system. We use a series of thick, self-sharpening serrated knives which means that the wood and green waste is actually cut, whereas most competitors machines use thinner hammers to just smash the material. Other effects of this are slower processing of green waste, plus more vibration and noise, which makes them frustrating and slow to use. When you purchase a Bear Cat you also have the peace of mind of knowing you have a well-established company to provide parts back-up, and support if needed. Bear Cat machines come with a 1 year commercial warranty and a 2 year domestic warranty.
