Recommended Accessories
For best performance, it is recommended to use tire chains and two (2) rear wheel weights. A rear-mounted
weight box can also be added for additional traction. The maximum weight added to the tractor should not exceed
35 lbs./wheel, plus100 additional pounds in the rear weight box.
An Electric Lift Kit is available for the 14 HP Landlord/1700 Series tractors to raise and lower attachments.
Required Accessories
A Lift Lever Kit is required for the following models, and must be installed prior to hitch installation.
- Broadmoor/LT/1600/2600: Lift Kit, mfg. no. 1691832
- Regent/500/2500Series: Lift Kit, mfg. no. 1692623

Read these safety rules and follow them closely. Failure to obey these rules could result in loss of control
of vehicle, severe personal injury to yourself or bystanders, or damage to property or equipment. The tri-
angle in the text signifies important cautions or warnings which must be followed.
General
•Read the operator’s manual carefully. Be thor-
oughly familiar with the controls and proper use of
the equipment. Know how to stop the unit and dis-
engage the controls quickly.
•Never allow children to operate the machine. Do
not allow adults to operate it without proper
instruction.
•Keep the area of operation clear of all persons,
particularly small children and pets.
•Do not carry passengers.
•Make sure:
a. tractor and attachments are in good operating
condition.
b. all safety devices and shields are in place
c. and in good working condition, and
d. all adjustments (skid shoe height, etc.) have
been made.
Preparation
•Handle gasoline with care — it is highly flamma-
ble.
a. Use only an approved gasoline container.
b. Never remove the cap of the fuel tank or add
gasoline to a running or hot engine, or fill the
fuel tank indoors. Wipe up spilled gasoline.
•Do not run the engine indoors. Exhaust fumes are
dangerous.
•Shift into neutral before attempting to start the
engine.
•Wear proper footwear. Do not operate tractor
when barefoot or when wearing open sandals or
canvas shoes.
Operation
•Do not allow anyone to use the snow plow/dozer
blade unless they have been instructed on how to
operate it safely.
•Never attempt to adjust, repair or service the snow
plow/dozer blade while the tractor engine is
running.
•Do not allow others near the snow/dozer blade
while it is being used.
•Use the snow plow/dozer blade only in daylight, or
good artificial light.
•Always lower the snow plow/dozer blade com-
pletely to the ground when leaving it unattended to
prevent it from being accidentally lowered and
causing injury. Make sure blade is locked in
“DOWN” position due to spring-assist.
•Always operate the tractor at reasonable speeds
to prevent the blade from catching an object and
stopping the tractor abruptly.
Safety Rules
WARNING
For operation on slopes greater than 15% (8.5°),
weight box, tire chains, and wheel weights are rec-
ommended. Never operate on slopes greater than
30% (16.7°)

Removal
1.Lower the blade.
2.Remove blade and lift rod from push bar.
3.Raise push bar and unhook the spring from the
chain. Remove the chain from the frame bracket.
Reinstall safety clip to clevis pin.
4.Disconnect the lift rod from the lift lever on tractor
by removing the spring clip.
Set tractor speed to obtain the needed power to move
the material. Operate at a safe speed, depending on
conditions, so that you have complete control of the
tractor. Rear wheel weights and chains are recom-
mended for slippery surfaces.
A weight box is recommended for additional traction.
Operation On Slopes
Never operate on slopes greater than 30 percent
(16.7°) which is a rise of three feet (91 cm) in ten feet
(305 cm) forward. Use two rear wheel weights (one
per wheel) when operating on slopes greater than 20
percent (11.3°).
For additional traction, tire chains and a weight box
can be added. Maximum weight added to tractor
should not exceed 35 lbs. per wheel and 100 addition-
al lbs. in weight box.
Always operate up and down the face of slopes, and
never across the face. Use a slow ground speed on
slopes.
Normal Care
After dozing jobs, hose down the blade to remove
excess dirt. Coat bare metal surfaces to prevent rust-
ing. Lightly oil all pivot points.
If the wear plate on bottom of the blade is worn
excessively, replace it with a new one by removing
the six carriage bolts.
Operation & Normal Care
Transporting
For maximum ground clearance, transport the blade
to and from work areas fully raised and angled
straight ahead.
Dozing and Snow Plowing
When dozing, push the dirt to the desired location,
then drag the blade backwards for final leveling. Pack
down the dirt or gravel by driving the tractor over the
leveled area.
Use the grade of the area being plowed or dozed to
your advantage. Plow downhill and set the blade
angle so that plowed material (especially snow) is
moving downhill as it leaves the blade. To change
blade angle, pull out the blade pivot pin. Pivot the
blade to one of the other three holes and reinstall the
pivot pin.
For large drifts of snow, plow narrower paths instead
of attempting to plow a full blade width.
WARNING
Be particularly careful and operate at low
tractor speeds in any area where the blade
can hook on solid objects. Such objects can
cause the tractor to be jarred or come to an
abrupt stop.
5.Remove the latch rod and spring clip securing
push bar to tractor frame brackets, or clevis pins
and spring clips securing push bar to hitch rail
extensions. Remove push bar.
6.Reinstall all pins (king pin, pivot pin, hitch pin) and
secure with spring clip or safety clip for storage.

Lift Rod
See Figure 17. For initial setting, place front set collar
(A) one inch from rod guide with blade fully lowered.
Place rear set collar (B) against spring (C). Tighten
the setscrews in the two set collars.To adjust, perform
the following:
1.Fully raise the blade by pulling back on the tractor
lift lever. Measure distance between scraper bar
and ground. If it measures approximately six inch-
es, it is properly adjusted. If not, proceed to step 2.
2.Lower the blade. Loosen the setscrew in the front
set collar. move the set collar back to increase
ground clearance, forward to decrease ground
clearance. Tighten the setscrew. Recheck the
measurement.
NOTE: Different ground contours may require differ-
ent adjustments. Moving the rear set collar toward
rear will allow the blade to follow a rolling contour.
Lower the blade to adjust the rear set collar. The far-
ther back the rear set collar is positioned, the more
the blade will float. Moving the rear set collar toward
the front will increase down pressure.

A. Skid Shoes

Skid Shoe Adjustment
Slotted holes are provided to permit adjustment of the
shoe assemblies for raising and lowering the blade to
various working heights (see Figure 18).
When cleaning snow from gravel or earth drives or
walks, the shoe assemblies should be lowered fully to
prevent blade contact with gravel or ground. When
cleaning smooth hard surfaces like concrete, the shoe
assemblies are normally placed fully up to allow the
blade to scrape the surface.
To adjust the skid, raise the blade off the ground and
block with a piece of wood. Loosen the bolts (B,
Figure 18) and move the skid shoes (A) up or down to
desired height. Tighten the bolts securely.

15
Adjustments
Spring Tension
See Figure 19. This snow plow/dozer blade is spring
loaded so that when the blade strikes a solid object,
the springs will allow the blade to release as shown,
rather than cause damage. The blade will go back to
its original position after object is cleared.

C. Spring
See Figure 20. To adjust spring tension hold rear nut
(B) and loosen front nut (E). Tighten rear nut (B) to
increase spring tension, or loosen to decrease ten-
sion.
For initial adjustment, tighten nut (B) on each eyebolt
enough to expose about 3/4" (19mm) of thread.
Tighten front nut (E) against rear nut (B) to lock
adjustment in place.
