A. ASSEMBLY OF MOWER WHEELS
1. Set the mower deck assembly on wood blocks so that it is suspended off the ground.
Retainer Bolts
Tongue Pivot Bolt Tongue – Attach to Either
Left or Right Caster Assy.
Left Rear Axle Assy.
Left Caster Assy.
Figure 1. Assembly of Wheels, Tongue and Rear Hitch
2. Install the two caster assemblies in the retainers on the front of the mower deck. See figure 1.
Before securing the caster supports, determine which side of the mower the tongue will be
placed on and install the caster support stop on the tongue side. See Figure 2. Secure with
3/8” x 2-3/4” hex head bolt, lock washer, and nut provided in the retainer areas.
Note: The operator controls are on the front of the deck and the discharge chute is on the right
side. (Left and right are determined from looking in the direction of travel.)
3. Install the two rear axle assemblies in the retainers on the rear of the mower deck. The tire
should be to the left of the axle support. See figure 1. Secure with 3/8” x 2-1/2” hex head
bolt, lock washer, and nut provided in the retainer areas.

B. INSTALLATION OF LAWN & GARDEN HITCHING (refer to the Operation and Adjustment
Section for recommended hitching)(if the ATV Tongue was purchased refer to section C.
Installation of ATV Tongue)
1. The tongue can be installed either on the left or right caster assembly depending on how the
wing mower will be towed. See figure 1. Tighten the lock nut on the 3/8” x 2-1/2” pivot bolt so
the tongue is free to pivot but does not move sideways.
Note: The tongue can be installed upside down so it will match up with tow vehicles with
higher hitches.
2. The tow vehicle hitch provided is a universal hitch that should fit most tow vehicles. Slight
modifications may be necessary for some tow vehicles.
3. Attach the tow vehicle hitch to the tow vehicle draw bar top or bottom depending on best
support, and secure with the longer 1/2” hex head bolt, flatwasher, nut, and lockwasher
provided. See figure 3.
Note: On some tow vehicles the draw bar will need to be strengthened to support the hitch
assembly securely.
4. Adjust the hitch stop angle with stop bolts as close as possible to the vertical member on the
back of the tow vehicle and adjust stop bolts securely against vertical member to keep hitch
from pivoting from side to side.
Note: The hitch should be positioned on the tow vehicle so the stop bolts have a solid member
to adjust to. On most tow vehicles two bolts can be used to attach the hitch assembly to
the draw bar, eliminating the need for the hitch stop angle.

5. The telescoping hitch can either be installed to the left or right and should clear the back of the
tire by about 2”.
6. If one mower is pulled on both the left and right side of the tow vehicle, then one telescoping
hitch can be mounted to the left and one to the right.

C. INSTALLATION OF ATV TONGUE ASSEMBLY (if the lawn and garden hitching was purchased
refer to Section B. Installation of Lawn & Garden Hitching)
1. The tongue can be installed either on the left or right caster assembly depending on how the
wing mower will be towed. See figure 4. Secure the hitch pivot on the chosen caster
assembly with the 3/8” x 2-1/2” hex head bolt, lock washer, and nut provided.
2. Install the tongue into the hitch pivot and secure by placing a 5/16” wire lock pin on each side
of the hitch pivot.
D. INSTALLATION OF OPTIONAL HITCHES
1. When a long tongue is needed, remove the tongue pivot angles and spacer from the tongue
assembly and attach to the tongue extension. See figure 5. Slip the tongue in between the
two flats on the tongue extension and secure with 3/8” x 2-1/2” hex head bolts, lock washers,
and nuts provided.
2. When a second mower is pulled behind the first mower in tandem, then the rear hitch can be
installed on the left rear axle assembly. See figure 5. Secure with 3/8” x 3-1/4” hex head
bolts, lock washers, and nuts provided.
Note: The long tongue extension (Part # 900008) and rear hitch assembly (Part # 900009) must
be ordered separately.

Figure 6: Wing Mower Towing Suggestions and Required Hitches

The hitching system is designed so that the wing mower can be pulled directly behind a tow
vehicle without a mower deck or as a left or right wing mower when towed behind a tow vehicle
with or without a mower deck.
If more than one wing mower is towed, they can be pulled in tandem or one on the left and one on
the right or a combination of the above conditions until the desired cutting width is obtained.
Do not operate two wing mowers in tandem on slopes greater than 25% (1 foot rise, 4
foot run). This can create an unstable condition where the rear wing mower could
push the front wing mower sideways.
When mowing large open areas, adjust the spreader hitch on the tow vehicle so that the wing
mower tongue center line aligns with the outside cut line on the tow vehicle mower. When
trimming around objects or mowing contours, it is best to adjust the tow vehicle hitch in to
eliminate skips. The spreader hitch can be adjusted in and out to get the desired overlap to fit
your mowing job.
B. ATV TONGUE CONFIGURATIONS (Refer to Figure 6)
Shut off the engine and allow the mower blades to come to a complete stop before
adjusting the tongue.
When attaching the tongue to the back of the tow vehicle, tighten the screw pin
shackle clevis firmly. Property damage or bodily injury may occur if the screw pin
shackle clevis unturns and the wing mower becomes unattached from the tow
vehicle.
The hitching system is designed so that the wing mower can be pulled directly behind a tow
vehicle without a mower deck or as a left or right wing mower when towed behind a tow vehicle
with or without a mower deck.
Note: When pulling the wing mower directly behind, it is most maneuverable when the hitch
pivot is fastened on the left carrier arm. See Figure 4.When pulling the wing mower in
the offset position, it is most maneuverable to have the hitch pivot fastened on the right
carrier arm. See Figure 4.
The tongue is designed to adjust from left to right within the hitch pivot. This allows the wing
mower and tow vehicle, with a mower deck, to have proper overlap. Overlap is more critical in
tight areas where a lot of maneuvering is required. This overlap will eliminate most skips between
the tow vehicle and wing mower. In large open areas the overlap is not as critical and should be
adjusted to the user’s preference.

C. ADJUSTING CUTTING HEIGHT
Shut off all engines and allow the mower blades to come to a complete stop on the
wing mowers and on the tow vehicle before adjusting the cutting height.
The cutting height can be adjusted in a range from 1.0" to 4.0". This is accomplished by adjusting
the height adjusting bolts on each of the four corners of the wing mower. See Figure 7. Turn the
bolts clockwise to raise the mower cutting height and counter-clockwise to lower the mower
cutting height.
When more than one mower is used at a time, it is very important to have all the mowers adjusted
as close to the same cutting height as possible to obtain a high quality cutting job.
Adjust the mowers as follows:
1. Pull the mowing unit on to a smooth, level surface.
2. Adjust the tow vehicle mower deck (If applicable) to the desired cutting height and level both
fore and aft and side to side.
3. Measure the distance from the level surface to the mower blade cutting edge on the tow
vehicle.
Shut off tow vehicle engine and allow mower blades to stop completely before
attempting to measure the cutting height.

Start engine and move throttle toward slow position to disengage choke. The mower blades
clutch will engage as the engine comes up to speed. The mower blades clutch engages at
1850 RPM.
Slow engine speed to idle to allow engine to warm up. This will probably allow the mower blade
clutch to fully disengage.
Adjust engine speed toward fast to fully engage the mower blade clutch. (The full throttle is
located at the first detent position on the throttle control.)
Clutch overheating or failure may occur if engine is not run at full speed in heavy
load conditions.
The engine full speed setting with mower blades running is 3350 RPM.
For Model E60B:
Set the throttle lever in the choke position to set the choke. (The throttle lever is located on the
right side of the engine.)
Start engine and move throttle toward slow position to disengage choke.
Slow engine speed and engage mower blades clutch handle. (The clutch handle is located at
the front of the mower under the engine.)
Note: Some belt squealing may occur on engagement. This is normal for a manual clutch
engagement design.
If the mower’s engine happens to quit while in use take care to remove the wing
mower from the uncut area before attempting to engage the clutch. Also inspect the
blades for any obstructions that may prevent blade engagement. Failure to do either
may result in premature belt failure or even a fire.
Adjust engine speed to fast position for full throttle. (The full throttle is located at the detent
position on the throttle control.)
E. SHUTTING OFF WING MOWER
Shift to neutral, disengage power to the mower deck, and set the parking brake
before dismounting the tow vehicle.
For Models H60T & C60K:
Set the throttle to slow so the mower blades clutch will disengage.
Allow engine to cool down for a short time before turning the engine off.
