NOTE: These mulchers include a 6mm allen wrench and 19mm wrench to adjust the displacement
screws.
SETUP
MOTOR DISPLACEMENT
Due tothe range ofprime movers the DIGGA Series IIMagnum Mulcher isdesigned for, the motor
minimum displacement isadjustableto various LPM and rotor RPM togive you optimum productivity
for your particular application. The displacement must be adjusted and then “locked in”. For optimum
productivity and proper operation the minimum displacement on the mulcher motor needs to be
adjusted for the “ACTUAL” LPM of your primemover and the desired RPM of the mulcher rotor. With
the engine at full throttle, setthe rotor RPM between 1800 -2000 RPM. (Factory settings are 50 CC on
all skid steer loader mulchers, 66 CC on the combination and excavator mulchers and 76 CC on the
forestry mulchers.)
NOTICE:Insufficient RPM (below 1800) will greatly reduce the productivity ofyour unit while over
speeding (above 2000) can causeserious damage to the motor and teeth.
See the following charts for correct adjustment of the minimum displacement screw for the motor
minimum displacement.
NOTE: To Adjust Minimum Displacement Screw, loosen and hold the locking nut while turning the
minimum displacement screw tothe desired dimension and then holdthe limit screw while turning the
locking nutand therefore locking it inplace.
It isrecommended that the drum RPM be checked with a tachometer after adjustments have been
completed. Toincrease RPM, increase “X” dimension. To decrease RPM decrease the “X” dimension.
The maximum displacement limit screw is adjusted at the factory.
IMPORTANT:Primemover must be at operating temperature prior to checking the rotor RPM with
tachometer.

GENERAL INFORMATION
TheDIGGA Series IIMagnum Mulchers were designed to be easy touse and maintain. The 60”
mulchers areavailablewith skid steer onlymounting, excavator onlymounting or a combination
mulcher that canbe easily changed from skid steer mounting toexcavator mounting. A special 60”
mulcher isdesigned for a universal skid steer hitch forestry vehicle. When installing a hydraulic 3-line
mulcher onto your primemover acontrol box assembly #15754 or a pigtail adaptor harness for in-
cab controls isrequired to operate the deflector door.
NOTICE: Do not operate the Digga Series II mulchers on standard flow hydraulic systems.
NOMENCLATURE
Throughout this manual, reference is made tovarious mulcher components. Study the following
diagrams to acquaint yourself with the various names ofthese components. The combination
mulcher isnot shown but has components from both attachments shown below. This knowledge will
be helpful when reading through this manual orwhen ordering service parts. There is a complete
parts breakdownfor each mulcher at the back ofthis manual.

SECURELY LATCHED TO THE ATTACHMENT MECHANISM OF YOUR UNIT.
FAILURE TO DO SO COULD RESULT IN SEPARATION OF THE ATTACHMENT
FROM THE UNIT. CLEAR THE AREA OF ALL BYSTANDERS DURING
INSTALLATION.
ATTACHING -EXCAVATOR
A separate mounting kit is required to install the DIGGA Series II Mulcher onto your excavator. Install
the mounting bracket to the mulcher mounting plate. Install the mulcher to your excavator by following
your prime mover operator’s manual for proper installation of an attachment. When attaching the
hoses to the excavator, the case drain line (“CD” port) must be connected first, then the power (“P”
port) and return (“T” port) hoses. When disconnecting the hoses, it is recommended to disconnect the
case drain line last. This will prevent any over pressurization of the motor case on the mulcher head.
NOTE: The case drain line must be installed from the mulcher head to the excavator hydraulic tank.
The case drain line must be unrestricted all the way to the tank.
IMPORTANT: Over pressurization of motor case can be caused by a kinked or pinched hose, improper
connection and obstruction or damaged coupler on the case drain line. Make any necessary
adjustments and/or reroute hoses before operating. Route hoses in such a fashion to prevent pinching
or chafing.
WARNING! TO AVOID SERIOUS PERSONAL INJURY, MAKE SURE THE MULCHER IS
SECURELY LATCHED TO THE ATTACHMENT MECHANISM OF YOUR UNIT.
FAILURE TO DO SO COULD RESULT IN SEPARATION OF THE ATTACHMENT
FROM THE UNIT. CLEAR THE AREA OF ALL BYSTANDERS DURING
INSTALLATION.
INSTALLATION
NOTE:Before attaching the mulcher to your prime mover, make sure a forestry guard package has
been installed onto the primemover. This isrequired toprotect the operator from possible thrown
objects.
ATTACHING -UNIVERSAL SKID STEERMOUNTING
Install the DIGGA Series IIMulcher by following your primemover operator’s manual for proper
installation of an attachment. When attaching the hoses tothe primemover, the case drainline (“CD”
port) must be connected first, then the power (“P” port) and return (“T” port) hoses.
When disconnecting the hoses, itisrecommended to disconnectthe case drain line last. This will
prevent any over pressurization of the motor caseon the mulcher head. Foroperation of the deflector
door on 3-line hydraulic mulcher, install control box #15754 to electrical harness on mulcher orinstall a
pigtail adapter to adapt the wiring harness on the mulcher to your in-cab controls (if so equipped).
IMPORTANT:Over pressurization of motor casecan be caused by akinked or pinched hose, improper
connection and obstruction or damaged coupler on the case drain line.
Make any necessary adjustments and/or reroute hoses before operating. Routehoses in such a fashion
to prevent pinching or chafing.
WARNING! TO AVOID SERIOUS PERSONAL INJURY, MAKE SURE THE MULCHER IS

ATTACHING -COMBINATION MULCHER
The combination mulcher can be mounted to a skid steer loader or excavator.
NOTE: The attachment ships skid steer ready. See “CHANGING COMBINATION MULCHER
MOUNTING” for changing from skid steer mounting to excavator mounting and back again.
Install the mulcher to your skid steer or excavator by following your prime mover’s operator’s manual
for proper installation of an attachment. When attaching the hoses, the case drain line (“CD” port) must
be connected first, then the power (“P” port) and return (“T” port) hoses.
When disconnecting the hoses, it is recommended to disconnect the case drain line last. This will
prevent any over pressurization of the motor case on the mulcher head.
NOTE: If installing onto an excavator the case drain line must be installed from the mulcher head to
the excavator hydraulic tank. The case drain line must be unrestricted all the way to the tank.
IMPORTANT: Over pressurization of motor case can be caused by a kinked or pinched hose, improper
connection and obstruction or damaged coupler on the case drain line. Make any necessary
adjustments and/or reroute hoses before operating. Route hoses in such a fashion to prevent pinching
or chafing.
WARNING! TO AVOID SERIOUS PERSONAL INJURY, MAKE SURE THE MULCHER IS
SECURELY LATCHED TO THE ATTACHMENT MECHANISM OF YOUR UNIT.
FAILURE TO DO SO COULD RESULT IN SEPARATION OF THE ATTACHMENT
FROM THE UNIT. CLEAR THE AREA OF ALL BYSTANDERS DURING
INSTALLATION.
DETACHING
On firm, level ground. Lower the mulcher to the ground. Follow your prime mover operator’s manual to
relieve pressure in the hydraulic lines. Disconnect couplers. When disconnecting the hoses, it is
recommended to disconnect the case drain line last. This will prevent any over pressurization of the motor
case on the mulcher head.
NOTE: Connect couplers together or install dust caps and plugs to prevent contaminants from
entering the hydraulic system. Store hoses on attachment off the ground.
Disconnect the auxiliary electrical connection or the control box from the prime mover and secure the
wire harness to the attachment (if so equipped).Follow your prime mover operator’s manual for
detaching (removing) an attachment.
WARNING! CLEAR THE AREA OF ALL BYSTANDERS DURING REMOVAL.
IMPORTANT: Disengage the auxiliary hydraulics, stop the engine, engage parking brake and remove
key before leaving the operator’s station.
