HOC8A 8 Inch PTO Wood Chipper - With Auto Infeed (2024)

The HOC8A 8 Inch Wood Chipper with Auto Infeed is a durable PTO-driven attachment designed for tractors. It's compact and an absolute workhorse. Featuring USA made knives among many other North American parts the unit is welded, assembled, and tested in Canada prior to every shipment.

STRENGTH:

HOC8A chippers are built with Canadian made Structural Steel, CNC plasma cut, and meticulously welded in Canada boasting impressive strength in their design. Our design includes a 2" diameter main shaft supported by three bearings (1 pillow block and 2 flange bearings), which adds a significant amount of strength.

LARGE DIAMETER DUAL INFEED ROLLERS

The large diameter in-feed rollers measuring over 6 inches efficiently pulls material into the flywheel at approximately 58 feet per minute. The dual rollers are made of high carbon steel chisel teeth and are spaced out to prevent debris buildup. The roller's self-cleaning ability enables the 165 lbs. of down pressure to concentrate on fewer teeth, thereby increasing their grip. HOCs in-feed rollers aggressively grab any size limb up to 8 inches in diameter without wrapping around the roller, an extremely effective feature.

STRONG GEAR BOX AND DRIVE AXLE

The HOC in-feed system employs a heavy-duty gear box filled with oil and driven by strong belts. This system enhances torque and transfers power to the upper feed roller through an extreme duty drive axle. The clutch is made of solid steel and machined with precision to guarantee its proper operation. With this in-feed system, material can be fed at a rate of up to 58 ft./min.

360 DEGREE DISCHARGE CHUTE

The HOC8A chipper features a discharge chute that can easily rotate 360 degrees. The chute is equipped with a handle that allows you to effortlessly direct the chips into a truck or trailer without having to reposition the entire machine.

WIDE ANGLED SUPPORT BASE

To ensure the machine remains stable and doesn't sink into soft ground during use, the HOC8A features a wide footprint skid support base with an angled end to prevent ground penetration.

EFFECTIVE SUCTION SYSTEM

The flywheel chamber of the HOC8A wood chipper provides a powerful suction. This suction draws air into the chamber and, when combined with the fan blades on the back of the flywheel, effectively expels the wood chips from the machine. This design ensures that the discharge chute stays unobstructed and minimizes the risk of a jam.

STEEL BEARINGS

The main shaft on the HOC chipper is supported by three shock-resistant cast steel bearings. These bearings are located on either side of the flywheel housing and are supported by flange bearings, making this unit highly durable and reliable.

HIGH ADJUSTABLE TENSION SPRINGS

The HOC chipper features high tension springs and a unique adjustment mechanism that provides a complete range of variable down pressure to accommodate branches of varying hardness. Users can adjust the upper roller down pressure by cranking up the tension to achieve 165 lbs. of down pressure!

EASY KNIFE ACCESS PANELS

Changing the HOC chipper knives can be done very easily, taking only a few minutes.

HEAVY DUTY DRIVE V-BELTS

HOC chippers are fitted with high-strength drive v-belts, measuring 5/8 inches in width, for maximum durability. These specialized belts transmit more torque than traditional smooth v-belts.

AUTO-FEED STOP BAR

Ensuring safety is a top priority for HOC. HOC 8" PTO chippers feature an auto-feed stop safety bar located on the top of the in-feed bin that is easy to activate. In the event of an emergency or to clear the in-feed bin, the safety bar stops the in-feed rollers.

FEED ROLLER ASSIST HANDLE

The handle on the HOC chipper is designed to be easily accessed from either side of the machine. Additionally, the center lift point enables the use of stronger tension springs, which enhances the chipper's in-feed ability.

CLEAR VINYL BAFFLE

The transparent vinyl baffle safeguards the operator from chips being blown back, while also enabling the operator to observe the activities inside the hopper.

ADJUSTABLE BASE LEGS

The HOC8A base legs can be adjusted to fit a wide range of tractors, making it easier to achieve the required PTO shaft angle. HOC PTO Wood Chippers can be adjusted to fit tractors with PTO heights ranging from 18" to 30".

MAIN SHAFT SUPPORTED BY 3 BEARINGS

The main shaft of the HOC PTO Wood Chippers has a diameter of 2 inches and passes through the flywheel housing, supported by one pillow block and two flange bearings. This design contributes to the accuracy of the flywheel's rotation and provides extra strength.

FLYWHEEL HOUSING

The flywheel housing of HOC’S chippers are constructed with 8mm thick heavy gauge structural steel. This thicker plate offers added strength and rigidity as the flange bearings are mounted on it.

ADJUSTABLE KNIVES

HOC Wood Chippers come with an adjustable bed knife to guarantee that the appropriate knife gap is attained. This capability allows users to regulate the space between the flywheel knife and the bed knife to ensure that the required distance is maintained even after knife sharpening or knife replacement.

RUST RESISTANT POWDER COAT

HOC Wood Chippers are coated with a powder finish that is baked on to avoid rust.

ASSURANCE

HOC chippers are designed to be highly durable and able to withstand heavy use. With years of experience and over 500,000 units in service today, we are confident that our chippers can handle even the toughest projects.
