Filtration system shall consist of a 10-micron spin-on return line filter with restriction bypass located in the hydraulic tank. The vented filler cap shall have a 10 PSI restrictor check valve.

HYDRAULIC FEED SYSTEM

Hydraulic feed system shall consist of two (2) horizontally mounted 23" circumference hydraulic driven feed wheels measuring 19" long minimum. The feed wheels shall have eight (8) sharpened steel blades designed to pull material into the cutting disc without slipping or wrapping.

Top feed wheel shall have four (4) 16" adjustable springs to insure ample down pressure. Upper feed wheel slide shall have four (4) nylon wear strips to allow smooth operation.

HYDRAULIC LIFT CYLINDER

The Hydraulic Lift Cylinder is a system that allows the chipper operator to raise and lower the top feed wheel by actuating a valve located at the rear of the chipper adjacent to the control bar. By raising the feed wheel, large diameter wood can be fed into the chipper with no resistance and by applying down pressure, wide brushy limbs can be crushed. When the Hydraulic Lift Cylinder is not activated the chipper operates in the normal or "manual" mode. The operator will have more control of the feeding process while saving valuable time reducing chainsaw use. In lift mode, the Hydraulic Lift Cylinder produces 2500 P.S.I., in lower mode 2500 P.S.I. The Hydraulic Lift Cylinder contains a 2" bore x 18" stroke cylinder.

A control bar shall be located on three (3) sides of the infeed chute allowing activation of feed wheels in the forward position (on), the neutral position (off) and the reverse position. The infeed chute shall be tapered for easy feeding and minimal drag restriction.

FEED RATE

Feed rate shall be approximately 65 ft./min. *May vary depending on options, engine and customer request.

TONGUE WEIGHT

Typical tongue weight shall be 250 lb. average at level (May vary as a result of power units and options)

CONTROLS

All controls shall be located curbside to eliminate operator from standing in street for engine start-up and PTO engagement.

"G" Series Features

PANIC BAR

This device, which is Patent Pending, will allow the operator to instantly stop all hydraulic functions from outside the feed horn by simply grabbing the "Panic Bar". This system must be reset to eliminate any accidental reactivation of the hydraulic system which acts as a "lockout" to insure that it is safe to resume operations before the hydraulic system will operate. The bar is readily accessed from both the operator's position and from the direction of the chipper engine giving personnel an almost 360 degrees from which to activate it outside of the infeed chute. Activation from inside the infeed chute is not acceptable.

DISCHARGE DEFLECTOR / CHUTE ADJUSTMENT BAR

This device allows the operator to adjust the chip deflector and the discharge chute position without climbing on the chipper. This will reduce the opportunity for an operator to fall during adjustment and also facilitate proper chute and deflector placement.

CHIPPER HOOD SAFETY LATCH

This system reduces the ability of an operator to open the hood while the disc is still rotating. It also reduces the chance of an operator starting the unit with the disc hood open.

FEED TABLE DESIGN

This redesign will allow the feed table to be less restrictive to the wood yet maintain the advantages of the previous table.

SOLID CHUTE ROTATION BRACKET

This enhancement will reduce the ability of operators to damage the chute rotation pin bracket.

CHIPPER HOOD LATCH

This feature allows the mechanic to latch the hood open at an angle of fewer degrees to help minimize the ability of careless mechanics to damage the hood when improperly released during opening and to reduce the ability of careless mechanics to over spring the hood hinge point.

INCREASED AIR INTAKE SYSTEM

This improvement will assist operators by reducing the ability to clog the discharge chute.
