INTRODUCTION
Product Description
The VENTRAC HM600, HM720 and HP720 mowers have a cutting width of approx. 60”
and 72” respectively. The “uni-body” design creates a lightweight, heavy-duty, and high
performance deck plus a streamlined carrier frame. With the removal of two pins
beneath the cross frame, the deck can be tilted to a near vertical position for cleaning
and servicing. The top side of the deck is designed to eliminate trapped grass, dirt and
water.
Four carrier points, two adjustable connecting links and one cross shaft comprise the
complete mechanism for controlling the cutting height. A single handle with a slight
outward pull allows an easy quick change in cutting height selection. A slide release
allows the handle to be returned to the deck level to prevent it from catching on low
branches and shrubs.
These mowers, with near full width rear rollers and large, pneumatic, front swivel caster
tires, are designed to float over the terrain independent of the tractor. The traction
transfer system on the VENTRAC 4000 series tractor reduces mower weight on the
ground, decreases the steering effort, and increases the traction of the tractor.
These attractive two-tone, smooth styled mowers with a high performance discharge
tunnel, offer an unusual combination of efficiency, effectiveness and end results.
Careful, proper, and safe operation of tractor and mower will result in a great mowing
job.
The model HP720 provides a 6-1/2” offset of the mower to the left side. The mower still
has a centered appearance because of the right side discharge chute. The offset
creates a better “reach” on the left side of the deck for mowing under low tree branches,
fences, or over the edge of ditches and water.

SAFETY
General Safety Procedures
for Ventrac Tractors, Attachments, & Accessories
Read and understand the operator’s manual before operating this equipment.
Observe and follow all safety decals.
DO NOT let children or any untrained person operate the tractor or attachment.
Make sure that all operators of this equipment are thoroughly trained in using it
safely.
Never allow additional riders on the tractor or attachments.
DO NOT operate tractor or attachments if you are under the influence of alcohol,
drugs, medication that may impair judgment or cause drowsiness, or if you are not
feeling well.
Operate all controls from the operators seat only.
Before operating equipment, make sure all shields are in place and fastened.
Ensure the attachment or accessory is locked or fastened securely to the tractor
(power unit) before operating. See tractor manual for locking procedure.
Ensure that all bystanders are clear of the tractor and attachment before operating.
Be especially careful and observant if other people are present. Never assume that
bystanders will remain where you last saw them.
Always look in the direction the tractor is moving.
Never direct the discharge of any attachment in the direction of people, animals,
buildings, vehicles, or objects of value.
Immediately stop at any sign of equipment failure and correct the problem before
continuing to operate. An unusual noise can be a warning of equipment failure.
Before adjusting, cleaning, lubricating, or changing parts on the tractor or attachment,
engage the parking brake, lower the attachment to the ground, stop the engine, and
remove the ignition key.
To prevent the risk of uncontrolled equipment movement on tractors equipped with 2
speed axles, always shift the transaxle range with the power unit stationary on level
ground and with the parking brake engaged.
If equipment is to be left unattended, engage the parking brake, lower the attachment
to the ground, stop the engine, and remove the ignition key.

SAFETY
HM600, HM720, and HP720 Safety Procedures
Before making any repairs or adjustments, lower
attachment to the ground, set parking brake, shut
the engine off, and remove the key.
Read and understand the operator’s manual before
operating this equipment.
Before mowing, clear the area of stones, sticks, and other foreign objects that can be
thrown by the mower.
Use extra care when mowing around trees, shrubs, and other objects that may block
your vision.
Never mow with the discharge chute flipped up or missing! The hinge feature is
provided only for transport and storage.
Disengage the PTO when you are not mowing.
When mowing on a steep incline, always mow uphill and downhill. Never mow across a
steep incline.

OPERATION
Operating Instructions
Attaching:
1. Drive the tractor slowly forward into the hitch arms of the mower. Align the lift arms
with the mower hitch arms by raising or lowering the front hitch and complete
the engagement. Note:
when mower cutting height is set in a low position. Set cutting height to the highest
position.
2. Once completely engaged, close the front hitch locking lever.*
3. Engage the parking brake and shut off engine.
4. Place attachment belt over the outside groove of the PTO drive pulley on the tractor.
Ensure the belt is properly seated in each pulley.
5. Engage the PTO spring tension lever.*
6. Engage the weight transfer system as desired.*
Note: It is recommended for most mowing operations that the weight transfer system be
fully engaged when using the mower deck. Adjust as required.
Mower arms may be too low to engage tractor hitch arms
Detaching:
1. Park the tractor on a level surface and set the parking brake.
2. Lower the mower to the ground.
3. Shut off tractor engine.
4. Disengage the PTO spring tension lever.*
5. Remove the attachment belt from the PTO drive pulley on the tractor.
6. Disengage the hitch locking lever.*
7. Restart the tractor and slowly back away from the mower.
*Refer to tractor manual for operation of controls.
Operating Techniques and Tips:
Be sure to select or confirm that the mower is set to cut the height that you prefer.
Setting is done by lifting the handle into the catch slot, pulling the handle outward and
moving the mechanism to another position on the adjustment scale. Cutting height
range is approximately 1-3/4 to 4-3/4 inches. After selection has been engaged, release
the handle from the catch slot and return it to a horizontal position. Never
height with PTO engaged.
adjust cutting
Operator must be sitting on the tractor seat before the PTO can be engaged. The tractor
engine should be running between 2,000 and 3,000 RPM before engaging the PTO
switch. Near full engine RPM (3,600) is recommended for most mowing. If a good cut
can be maintained and there is sufficient power, reducing the engine speed by 200 or
300 RPM will result in improved fuel economy and reduction in the wear-and-tear on the
equipment.
C-1
OPERATION
Operating Techniques and Tips (cont.)
Travel to and from the area to be mowed should generally be done with the
mower raised in transport position by the tractor hydraulics. This saves the
wear-and-tear on the mower and needless scuffing and rolling over the various
surfaces between mowing jobs. Moderate speed should be used in transport in
order to maintain control and reduce the shock load from uneven terrain.
Disengage the PTO to prevent air turbulence over dusty surfaces and/or when
traveling over rough terrain.
When mowing, always place the front hitch S.D.L.A. lever in the FLOAT position
by moving it outward to the second position until the detent engages. The lever
will stay in this position after engagement.
Wet or lush grass has some tendency to build up under the deck. Periodic
checking, especially if mowing performance seems to be reduced, will let the
operator know if the deck should be cleaned.
Many operators prefer to mow back and forth in order to create the popular stripe
pattern in the cut grass. The full length roller very effectively rolls the cut grass
in the direction of travel.
Blades should be kept in good condition. Sharp blades will increase
efficiency and improve the quality of cut.
When mowing grass on level to gently rolling terrain, the tractor can be
operated in HIGH range in most conditions. If the grass is tall or mowing
conditions are difficult, use LOW range. When mowing slopes, always
use LOW range with the engine at full throttle.
Be very cautious when mowing slopes. It is
recommended that weight transfer be engaged and
that the front hitch is set in FLOAT position.
