ASSEMBLY INSTRUCTIONS  
Read the complete assembly instructions before starting the assembly.  
You should have:  
- one mower deck assembly  
- two carrier arm assemblies  
- two rear tire assemblies  
- one front cross brace tube and one rear cross brace tube with height adjust assy.  
- one ATV tongue assembly  
A. ASSEMBLY OF REAR WHEELS AND CARRIER ARMS  
1. Set the mower deck assembly on wood blocks so that it is suspended off the ground.  
Note: The operator controls are on the front of the deck. (Left and right are determined by  
looking in the direction of travel or by standing at the rear of the deck assembly looking  
forward.)  
2. Install the rear tire assemblies on the carrier arm assemblies. Remove the hex nut and lock  
washer from the rear tire assembly and install the 5/8”x7-1/2” tire axle bolt through the hole in  
the carrier arm assembly. See figure 1. Secure assembly with the lock washer and hex nut  
provided on the rear tire assembly. The rear tires should be offset to the outside of the deck  
assembly on both sides. See figure 2.

3. Install the two carrier arm assemblies in the pivot arms, which are located on the mower deck  
assembly. Place the assembly so that the castered tires are on the front and the fixed tires are  
on the back. See figure 2. Secure with 1/2" x 3-1/2" hex head bolts and lock nuts provided on  
the pivot arms.  
Note: Tighten 1/2” x 3-1/2” hex head bolts until just snug. This area needs to pivot when  
adjusting the height. Under tightening can result in excessive wear and flexing. Over  
tightening will make adjusting the cutting height very difficult.

B. INSTALLATION OF CROSS BRACE TUBES AND HEIGHT ADJUST ASSY.  
For this section, if your mower was purchased with an Electric Lift Kit (Part #003912), refer to  
Section C of the Electric Lift Kit Owner’s Manual.  
1. Remove the 1/2” x 3” hex head bolts, lock washers and nuts that are located on the top of  
each carrier arm (four per carrier arm). The removed hardware will be used in step 2.  
2. Install the cross brace tubes on the carrier arms with the 1/2” x 3” hex head bolts, lock washers  
and nuts. Only hand tighten the hardware for this step. The support that has the height adjust  
assy. fastened to it needs to be placed on the rear location. Orientate the support such that  
the height adjust assy. hangs towards the engine. See figure 3.  
3. Remove the 1/2” x 1” bolt and lock nut from the lower deck mount. Manually turn the screw  
down towards the deck until the screw mounting flat hole lines up with the lower deck mount  
hole. After achieving alignment, attach the screw mounting flat with the 1/2” x 1” hex head bolt  
and secure the bolt with the provided lock nut. Do not over-tighten. This location must be able  
to pivot. See figure 4.

OPERATIONS AND ADJUSTMENTS  
This safety alert symbol is used to indicate safety instructions. Follow  
these instructions to avoid personal injury and/or property damage.  
Read and follow all instructions in this manual and the attached engine  
manual.  
WARNING: Do not allow anyone to operate this equipment who has not fully read and  
comprehended the safety manual and who has not been properly trained in the safe  
operation of the equipment.  
WARNING: Operator should be familiar with all functions of the unit.  
A. TONGUE CONFIGURATIONS AND ADJUSTMENTS  
WARNING: Shut off the engine and allow the mower blades to come to a complete stop  
before adjusting the tongue.  
The hitching system is designed so that the rough cut mower can be pulled directly behind a tow  
vehicle or offset to the left or right. See Figure 7.  
Note: When pulling the mower directly behind, the hitch pivot should be fastened on the right  
carrier arm for maximum maneuverability. See Figure 5. When pulling the mower in  
the offset position the hitch pivot can be fastened on either the right or left carrier arm.  
See Figure 5.

The tongue is equipped with a screw pin shackle clevis to provide movement in all directions on  
rough uneven ground. To prevent loss of the screw pin due to vibration or debris, place the screw  
pin through the tow vehicle hitch and clevis and turn the screw pin until snug.  
The tongue is designed to adjust from left to right within the hitch pivot. This allows the mowers  
position to be varied behind the tow vehicle. This is accomplished by pulling the 5/16” wire lock  
pins out and choosing two other hole locations on the tongue. See Figure 6.

The cutting height can be adjusted in a range from 2.0" to 8.0". This is accomplished by turning  
the height adjust crank located at the back of the mower. See Figure 8. Turn the crank clockwise  
to raise the mower cutting height and counter-clockwise to lower the mower cutting height.  
DANGER: Shut off tow vehicle engine and allow mower blades to stop completely before  
attempting to measure the cutting height.  
Adjust the mower as follows:  
1. Pull the mower on to a smooth, level surface.  
2. The desired cutting height can be determined by measuring the distance from the ground to  
the outside lower edge of the mower deck and adding 1-5/16”. The mower blade cutting edge  
is 1-5/16” above the outside lower edge of the mower deck.  
Note: If the height adjust crank does not turn easily, the pivot bolts holding the carrier arm  
assemblies and height adjust screw may be too tight. Loosen the pivot bolts slightly to  
allow easier pivoting. Care should be taken not to loosen too much or excess wear and  
flexing may occur. Greasing the threads on the height adjust screw may also allow  
greater ease in adjustment.  
Note: After setting the initial cutting height, quick field adjustments can be completed by  
counting crank turns. Roughly 8 turns will equal 1” of vertical movement.  
The adjustment crank may unturn due to vibration. This will allow the mower’s cutting height to  
change. The crank can be secured by folding it down between the adjustment nut tube and the  
height adjust support. See Figure 9.

C. STARTING ENGINE  
WARNING: Set parking brake on tow vehicle.  
Attach mower tongue to tow vehicle.  
WARNING: Do not start rough cut mower unless it is attached to the tow vehicle.  
Turn on fuel shut off valve which is located on the underside of the gas tank.  
Set the choke to the desired position.  
Set the throttle at approximately half throttle.  
Start engine and allow engine to warm up.  
Set engine speed at about half throttle and slowly 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.  
CAUTION: If the mower’s engine dies while in use, remove the rough cut mower from the  
uncut area before attempting to engage the clutch. Inspect the blades for any obstructions  
that may prevent blade engagement. Failure to follow these instructions may result in  
premature belt failure or a fire.  
Adjust engine speed to full throttle.  
D. SHUTTING OFF ROUGH CUT MOWER  
WARNING: Shift to neutral and set the parking brake before dismounting the tow vehicle.  
Slow the engine speed down to an idle and slowly disengage the clutch handle.  
Allow engine to cool down for a short time before moving the ignition switch to the off position.  
Turn off fuel shut off valve which is located on the underside of the gas tank.  
E. MOWER OPERATION  
DANGER: Keep hands, feet, hair and clothing away from moving parts.  
CAUTION: Clean or replace any safety signs that are not readable or damaged.

WARNING: Remove all objects from the work area that might be picked up and thrown by  
the blades.  
WARNING: Do not mow when children and others are around.  
WARNING: Do not fill fuel tank while engine is running or hot.  
WARNING: Keep all safety shields and deflectors in place during operation.  
CAUTION: Remove grass build up from under safety shields before each use. Do not  
remove safety shields while engine is running. Dry grass build up around belts and  
sheaves can cause fires.  
WARNING: Shut off engine before disconnecting the mower from the tow vehicle or  
attempting to move the wing mower by hand.  
WARNING: Never carry children or passengers.  
WARNING: Do not allow children to operate this machine.  
CAUTION: Slow down and watch the ends of the mower when making turns so objects  
are not struck and/or run over.  
WARNING: Look down, to the sides, and behind before and while backing to avoid  
backing over something or someone. Care should also be taken while backing so that the  
wing mower or mowers do not jackknife and damage hitches.  
WARNING: Stop the mower blades on the mower if the tow vehicle becomes stuck or  
stops going forward because of loss of traction. Shut off the engine on the mower before  
attempting to push or pull the tow vehicle.  
Listen to the rough cut mower engine while mowing. The engine should run free and not work too  
hard. Working the engine too hard will cause overheating and premature failure.  
CAUTION: If the mower’s engine dies while in use, remove the rough cut mower from the  
uncut area before attempting to engage the clutch. Inspect the blades for any obstructions  
that may prevent blade engagement. Failure to follow these instructions may result in  
premature belt failure or a fire.  
Do not allow material to build up on the air inlet to the engine cooling system. Special care should  
be taken to make sure the engine is getting enough inlet air. Do not allow the engine cooling fins  
under the shroud to be blocked. If air flow over the engine is restricted, the engine could  
overheat.

F. DRIVE BELT REMOVAL AND TENSION – Refer to Figure 10  
WARNING: Shut off engine and allow mower blades to stop turning before making any  
adjustments or repairs.  
Remove the safety shields.  
Loosen the nuts on the spring-loaded idler; adjust bolt until the belt can be slipped off the idler and  
drive sheaves.  
Slip the belt down under the drive sheave and off the blade spindle sheaves.  
Install the new belt and then adjust the tension as follows: See Figure 10. Take special care to  
make sure that the belt is placed between the brake stud and the idler pulley.

With the clutch engaged, adjust the nuts on the spring-loaded idler adjuster bolt until the length of  
the spring is approximately 2-3/4”. This is the initial belt break in spring length. When the belt is  
broken in after several hours of mowing, the running spring length should be between 2-3/4” and  
3-1/4”. For maximum belt life, periodic checks every 3-4 hours should be done to make sure the  
spring length has not exceeded the recommended running length.  
Note: Failure to periodically adjust the belt tension will result in severe belt wear and  
premature belt failure.  
This model comes with a belt brake, which is a safety feature that stops the blades from turning  
after the clutch is disengaged. The only time the brake should be in contact with the belt is when  
the clutch is disengaged.  
CAUTION: The brake stud may need to be adjusted if there is significant belt wear or if a  
different size belt is used. If the brake stud is not adjusted correctly, the blades will still  
spin even though the clutch may be in the disengaged position. Always shut mower  
engine off before servicing.  
Under normal operating conditions and when using the Kunz Engineering belt (Part # 238007) the  
brake stud should require very little adjustment. Periodic brake stud inspections should be  
performed every 10 hours. In more severe cutting conditions, more frequent inspections may be  
necessary. There are two parts to inspecting the brake stud. Those two inspections are the  
disengaged spring length and brake stud clearance.  
Note: It is quicker to perform the disengaged spring length and brake stud clearance  
inspections if done simultaneously.  
Disengaged Spring Length:  
This inspection must be performed to make sure that there is proper braking force to prevent the  
blades from spinning when the clutch is in the disengaged position. With the clutch in the  
disengaged position measure the spring length. The spring must be between 3-1/4” and 4” to  
provide the appropriate braking force. If the spring length is over 4” it will be necessary to adjust  
the brake stud closer to the belt. If the spring length is less than 3-1/4” it will be necessary to  
adjust the brake stud further away from the belt. To make brake stud adjustments loosen the bolt  
on the top of the brake stud and slide the brake stud in the slot. When the proper disengaged  
spring length is achieved, tighten the bolt on the top of the brake stud. For this procedure do not  
adjust the spring length. The spring length should only be changed when adjusting the belt  
tension.  
Brake Stud Clearance:  
This inspection is necessary to prevent over-braking. To inspect the brake stud clearence it is  
easiest to remove the left belt sheild and observe from the left side. With the clutch engaged,  
check to make sure that there is at least 1/2” of clearance between the brake stud and the belt. If  
the clearance is less than 1/2” then it will be necessary to adjust the brake stud away from the  
belt. Keep in mind that the disengaged spring length must stay between 3-1/4” and 4”.

Download from Www.Somanuals.com. All Manuals Search And Download.  
Note: If the brake stud is adjusted to the end of the slot and the brake stud clearance is under  
1/2” then it is time to replace the belt.  
CAUTION: If brake stud is not set in correct position, under-braking or over-braking may  
occur. If over-braking occurs, premature belt failure or a possible fire could occur due to  
excessive friction and overheating.  
G. MOWER BLADE REMOVAL, BALANCING & INSTALLATION  
CAUTION: Sharp blades can cause bodily injury if not handled properly.  
When removing the blade, it is recommended that a block of wood be placed between the blade  
and the underside of the mower deck. This will allow the removal of the blade without the need to  
hold the blade by hand.  
CAUTION: Always balance the mower blades each time they are sharpened.  
Out of balance mower blades cause excessive vibrations which lead to premature bearing  
failures, bolts coming loose, and overall deterioration of the mower.  
CAUTION: Always properly tighten the blade bolts to the specified torque. Failure to do so  
can lead to unwanted loosening of the blade and damage to the blade holding saddle.  
The Models MR44K and MR44B use the Kunz Engineering Part # (202141) blade bolt. This  
particular hex head bolt is a 3/4” – 16NF x 1-1/4” long, grade 5 and its proper torque is 300 ft-lbs.  
To ease in the blade installation process, use the same block of wood and method used during  
the removal of the blades.  
H. LUBRICATION  
There are five lubrication points on the rough cut mower -- one spring-loaded idler pivot, two  
caster wheel pivots, and two blade spindles. Lubricate at approximately 10 hr. intervals or more  
often as required in dusty conditions. Lubricate the blade spindles 2-5 pumps every 50 hours.  
(The bearings have trash guard seals to hold the seals in place during lubrication.) Lubricate with  
a high grade of pressure gun grease.  
Note: Do not over grease blade spindles. Blade spindles are initially greased at the factory.  
Greasing before 50 hrs. may cause bearing seal damage which will result in premature  
bearing failure.  
I. STORAGE  
Turn off fuel shut off valve which is located on the underside of the gas tank. If the mower is  
stored outside, the engine should be covered to prevent water from getting inside the engine  
during heavy rainstorms. See the Engine Manual for additional information.
