Valby CH222HF Woodchipper

A Chipper for Highway Departments

    The Valby CH 222 woodchipper is designed for efficient and safe disposal of stems, branches and bushes along roadsides.  The chips can be blown into a truck or back to the roadside.

    The chipper is fed from the right side so the feed is close to the material to be chipped.  The operator stands  on the road, away from the ditch and the traffic.  The feed chute does not stick outside the width of the tractor.   The tractor can therefore be driven safely on the right side of the road without risk of the feed chute hitting road signs or railings.

    The aggressive power feed makes the CH 222HF also the perfect machine for Christmas tree disposal.

A Chipper For Orchards

    The Valby CH 222HF is easy to use in orchards.  It can be maneuvered between narrow rows as neither the feed nor the discharge chutes stick out beyond the width of the tractor.

Ease of Operation

    The low feeding point ensures effortless feeding of the chipper.   The operator can stand with a straight back.  The discharge direction is adjustable 360 degrees.

    The chipper stands up by itself on the ground and is easy to hook up or remove from the tractor.

Power Requirements

   Due to the inertia of the heavy and large rotor, power units down to 35 HP can be used.  About 7 HP is required for every inch of round wood diameter.   Thus, to chip a 5-inch round wood, you need a 35 HP tractor      (7 X 5 = 35).

Hydraulic Feed

    The hydraulic feed is powered from the outlets on the tractor.  The operator can select feed, stop and reverse from the bar on top of the feed chute.  The turning speed of the rollers is continuously adjustable from a knob on the hydraulic valve.  The bottom feed roller is fixed.  The top roller is spring loaded.   The spring tension is adjustable.  The material is squeezed between the two rollers.

    The hydraulic feed chutes are close to the ground so quite heavy trees can be manually fed into the chipper.

    Minimum oil requirement is 4 GPM; maximum 18 GPM.  The oil might heat up if the reservoir is small.  If the oil reservoir is under 10 gallons, the operator should check for eventual overheating.  An oil cooler should be installed on the return line in case of overheating.

Safety Features

    The Valby chippers do not have any knife motion toward the operator-this reduces the risk of loose material flying back through the feed chute.

    The knives are counter-sunk into the disk, so the stress of chipping is absorbed by the entire backside of the knife, not just the knife bolts.

    The discharge height is 7'11" above ground so the discharge is above eye level.  To accomplish safe operation in various wind directions, the Valby chipper's discharge direction is adjustable 360 degrees. 

    The deflector bonnet enables placing the chips near or far.   The Valby chippers also have several noise-reducing features. The discharge opening is above ear level.  It is adjustable and can be directed away from the operator.  The hydraulic feed rollers cover the feed opening, thus reducing the noise level.
