UNIT ASSEMBLY

MODEL 2000

Your Giant-Vac Model 2000 PTO Blower comes fully assembled * and ready for
installation onto your tractor. (Follow the manufacturer’s instructions for proper
connection to the tractor.)
* The only assembly step required is the installation of the inner deflector door control

rod:

• Remove 1/2” lock nut from threaded stud end of control rod.

• Slide rod end through hole in control rod holder (the long angle piece with the large

hole on top, extending upward from the blower frame assembly).

• Insert threaded stud end of rod down through hole in inner deflector door control arm
and replace lock nut, tightening just enough to allow free, but not sloppy, movement
of rod.

MODELS 3200-4000

PRE-ASSEMBLY:

• Identify the following items inside the components box:

2 – Caster wheel assemblies
2 – Lower hitch point assemblies
2 – Support legs
1 – Top hitch point
1 – Hardware package

INSTALLING THE CASTER ASSEMBLIES:

• Remove the ½” x 1-1/4” bolt (Parts list ref. #24) and washers (#21-23) from the top of
each of the two caster assemblies. Also remove red caster spacers, but leave thrust
bearing (#18) in place.

• Slide top section of each caster assembly up through caster arm sleeves, replace
spacers, then secure with same hardware removed in previous step.

• Carefully tilt unit onto side so that caster wheels contact ground, then remove metal
skid. Note: Assistance is recommended, as weight of unit can cause serious
injury.

UNIT ASSEMBLY (cont.)

INSTALLING THE HITCH POINTS AND SUPPORT LEGS:

• Remove hardware holding each lower hitch point assembly together, and separate
pieces, making careful note of assembly configuration, as it will be
reassembled onto the shaft frame in the same manner.

• Slide lower hitch points (#51) onto side panels of shaft frame (#39) so that center
gap within hitch point receives edge of side panel into it. Note: Hitch pin (#61)
should be facing out. Align holes in hitch point with corresponding holes in bottom
outer corner of side panel, then insert four 1/2” x 3-1/2” bolts (#55, previously
removed from assembly) through mounting holes in each hitch point.

• Replace jack stand spacers (making sure to use two sets of - two ¼” spacers (#53)
and one 1/8” spacer (#52) - for each hitch point) and side support plate onto each
assembly, securing with lockwashers (#56) and nuts (#57). Tighten all fasteners
securely.

• Insert jack stand (#58) up through receiving hole of each lower hitch point assembly,
created by spacers and side support plate, securing with jack stand pin (#59) and
bridge pin (#60).

• Fasten top hitch point bracket (#47) to top of shaft frame using four 1/2” x 1-1/4” bolts
(#48), lockwashers (#49) and nuts (#50). Note: To aid in top hitch point

installation, shaft frame top cover plate (#45) removal is recommended *
*Helpful hint: Before replacing top cover plate, check shaft bearings for grease.

INSTALLING THE DISCHARGE DIRECTION CONTROL ROD:

• Fasten control rod support bracket (#40) to upper right side of shaft frame with two
1/2” x 1-1/4” bolts (#41), lockwashers (#42) and nuts (#43).

• Remove locknut (#38) from threaded stud end of control rod (#36). Slide rod through
hole in control rod support bracket. Insert stud through hole in discharge direction
control arm (#35) and secure with locknut, tightening just enough to give control arm
free (but not sloppy) movement.

Assembly of your Giant-Vac PTO Blower is complete. You are
now ready to mount your unit onto the 3-point hitch of your
tractor. Refer to the manufacturer’s instructions of your tractor
for information on proper connecting procedures.

UNIT OPERATION

GENERAL RULES TO OBSERVE BEFORE
AND DURING OPERATION:

• Be sure that you have connected the unit to the tractor correctly and securely,
carefully following manufacturer’s instructions.

• Follow the tractor manufacturer’s recommendations for safe operation.

• Clear the entire work area of all debris that could catch on or be thrown by the PTO

Blower. High velocity discharge can easily turn rocks and branches into dangerous
flying projectiles.

• Do not engage unit until you are ready to begin debris removal, and promptly
disengage unit as soon as operation is complete.

• Use proper discretion in selecting your cleaning pattern, especially on uneven
terrain. Avoid steep hills, especially if turf is wet. Do not travel straight down slopes
exceeding 14 degrees. If tires begin to slip when climbing a slope, the grade is too
steep for safe operation. Angle the tractor to a less steep slope until tires stop
slipping and traction is regained.

• Be keenly aware of the unit’s presence on the rear of the tractor, especially when
backing up or negotiating tight spaces and corners. Failure to do this can result in
serious damage to unit, tractor, and/or property.

• Be certain the P.T.O. lever is disengaged before turning off the tractor’s engine.

ENGAGING THE UNIT:

• With tractor engine running, set throttle to slow position, engage P.T.O. drive lever,
then slowly increase throttle to a maximum of 540 R.P.M. Caution: Never run the

tractor’s P.T.O. drive over 540 R.P.M. All Giant-Vac P.T.O. Blowers are
designed for a maximum

input of 540 R.P.M.

CHANGING DIRECTION OF DISCHARGE:

• Upon engaging the unit, all models discharge air initially from the left side of the
blower (driver’s perspective). However, right hand discharge can be achieved by
pulling the discharge direction control rod, located to the left rear of the operator and
easily accessible while seated on the tractor. This rod operates an inner deflector
door, which diverts air flow out to the right side. * This door is held in
