				Safety   
					• Inspect the area where the equipment is to be   
					used and remove all rocks, toys, sticks, wires,   
					bones, and other foreign objects which can be   
					thrown by the machine and may cause personal   
					injury to the operator or bystanders.   
					WARNING   
					Diesel fuel is harmful or fatal if swallowed.   
					Long-term exposure to vapors has caused   
					cancer in laboratory animals. Failure to use   
					caution may cause serious injury or illness.   
					• Avoid prolonged breathing of vapors.   
					DANGER   
					In certain conditions diesel fuel is extremely   
					flammable and vapors are explosive.   
					• Keep face away from nozzle and gas   
					tank/container opening.   
					• Keep away from eyes and skin.   
					• Never siphon by mouth.   
					A fire or explosion from diesel fuel can burn   
					you, others, and cause property damage.   
					• Check that the operator's presence controls,   
					safety switches, and shields are attached and   
					functioning properly. Do Not operate unless they   
					are functioning properly.   
					• Fill the fuel tank outdoors on level ground,   
					in an open area, when the engine is cold.   
					Wipe up any diesel fuel that spills.   
					• Never refill the fuel tank or drain the   
					machine indoors or inside an enclosed   
					trailer.   
					Operation   
					WARNING   
					Operating engine parts, especially the muffler,   
					become extremely hot. Severe burns can occur   
					on contact and debris, such as leaves, grass,   
					brush, etc. can catch fire.   
					• Do Not fill the fuel tank completely full.   
					Fill the fuel tank to the bottom of the filler   
					neck. The empty space in the tank allows   
					diesel fuel to expand. Overfilling may   
					result in fuel leakage or damage to the   
					engine or emission system.   
					• Allow engine parts, especially the muffler, to   
					cool before touching.   
					• Never smoke when handling diesel fuel,   
					and stay away from an open flame or   
					where diesel fuel fumes may be ignited by   
					spark.   
					• Remove accumulated debris from muffler and   
					engine area.   
					• Install and maintain in working order a   
					spark arrester before using equipment   
					on forest-covered, grass-covered, or   
					brush-covered unimproved land.   
					• Store diesel fuel in an approved container   
					and keep it out of the reach of children.   
					• Add fuel before starting the engine. Never   
					remove the cap of the fuel tank or add   
					fuel when engine is running or when the   
					engine is hot.   
					WARNING   
					Engine exhaust contains carbon monoxide,   
					which is an odorless deadly poison that can kill   
					you.   
					• If fuel is spilled, Do Not attempt to start   
					the engine. Move away from the area of   
					the spill and avoid creating any source of

					degrees   
					• Raise the roll bar as soon as clearance   
					permits.   
					2. Danger Zone-Use a walk behind mower and/or hand   
					trimmer on slopes greater than 15 degrees, near   
					drop-offs and water.   
					• Check carefully for overhead clearances (i.e.   
					branches, doorways, and electrical wires) before   
					driving under any objects and Do Not contact   
					them.   
					3. Water   
					• Remove or mark obstacles such as rocks, tree   
					limbs, etc. from the mowing area. Tall grass can   
					hide obstacles.   
					• In the event of a rollover, take the unit to an   
					Authorized Service Dealer to have the ROPS   
					inspected.   
					• Watch for ditches, holes, rocks, dips and rises that   
					change the operating angle, as rough terrain could   
					overturn the machine.   
					Maintenance and Storage   
					• Avoid sudden starts when mowing uphill because   
					the mower may tip backwards.   
					• Disengage drives, lower implement, set parking   
					brake, stop engine and remove key. Wait for all   
					movement to stop before adjusting, cleaning or   
					repairing.   
					• Be aware that operating on wet grass, across steep   
					slopes or downhill may cause the mower to lose   
					traction. Loss of traction to the drive wheels may   
					result in sliding and a loss of braking and steering.   
					• Keep engine and engine area free from   
					accumulation of grass, leaves, excessive grease   
					or oil, and other debris which can accumulate   
					in these areas. These materials can become   
					combustible and may result in a fire.   
					• Always avoid sudden starting or stopping on a   
					slope. If tires lose traction, disengage the blades   
					and proceed slowly off the slope.   
					• Let engine cool before storing and Do Not store   
					near flame or any enclosed area where open pilot   
					lights or heat appliances are present.   
					• Follow the manufacturer’s recommendations for   
					wheel weights or counter weights to improve   
					stability.   
					• Shut off fuel while storing or transporting. Do   
					Not store fuel near flames or drain indoors.   
					• Use extreme care with grass catchers or   
					attachments. These can change the stability of the   
					machine and cause loss of control.   
					• Park machine on level ground. Never allow   
					untrained personnel to service machine.   
					• Use jack stands to support components when   
					required.   
					Using the Rollover Protection System   
					(ROPS)   
					• Carefully release pressure from components with   
					stored energy.   
					A Rollover Protection System (roll bar) is installed   
					on the unit.

					Note: Determine the left and right sides of the   
					machine from the normal operating position.   
					Controls   
					Motion Control Levers   
					The motion control levers located on each side of   
					the console control the forward and reverse motion   
					of the machine.   
					Moving the levers forward or backward turns   
					the wheel on the same side forward or reverse   
					respectively. Wheel speed is proportional to the   
					amount the lever is moved.   
					Moving the levers outward from the center position   
					into the T-slot locks them in the neutral position

					be in the seat to start the engine.)   
					Tracking Adjustment Knob   
					Hour Meter   
					Located under the seat on the LH pump control link.   
					Located on the right fuel tank.   
					Rotating this knob allows fine tuning adjustments so   
					that the machine tracks straight with the drive levers   
					in the full forward position.   
					The hour meter is connected to a pressure switch   
					installed in the engine block and it records the   
					number of hours that the engine has run. If the   
					ignition switch is left on without engine running,   
					hour meter will not run.   
					Stop machine and wait for all moving parts to stop.   
					Engage park brake. Unhook seat latch and tilt seat   
					forward to gain access to the tracking knob. Rotate   
					the knob clockwise (as viewed from the rear of the   
					machine) to cause the machine to track more to the   
					right and counterclockwise to cause the machine   
					to track more to the left. Adjust in quarter-turn   
					increments until the machine tracks straight. Check   
					that the machine does not creep when in neutral with   
					the park brake disengaged.   
					Note: This switch is not a low oil sensor and will not   
					alert the operator if the engine oil is low.   
					Fuel Shut-Off Valve   
					Located directly below the right side of console, next   
					to the cubby.   
					The fuel shut-off valve is used to shut off the fuel   
					when the machine will not be used for a few days,   
					during transport to and from the jobsite, and when   
					parked inside a building.   
					Important: Do Not rotate the knob too far, as   
					this may cause the machine to creep in neutral.   
					Refer to the Motion Control Linkage Adjustment   
					section in Maintenance.

				Operation   
					PTO Engagement Switch   
					Warning Buzzer   
					Located behind the seat under the air deflector on   
					the electrical panel.   
					Located on right fuel tank.   
					Switch must be pulled out (up) to engage the blades.   
					Switch is pushed in to disengage the blades.   
					The buzzer is a warning signal that the engine   
					is overheating or the oil pressure is low. See the   
					Troubleshooting section.   
					Note: If the engine overheats, the PTO will   
					automatically disengage. The PTO cannot be engaged   
					until the engine has cooled down. To re-engage the   
					PTO, push PTO switch in to the disengaged position   
					and then pull out to engage. Refer to the Engine   
					overheats in the Troubleshooting section.   
					Note: If the engine coolant level is below the   
					indicator line on the overflow bottle when the engine   
					is cold, the warning buzzer may not sound if the   
					engine overheats. Refer to Check Engine Coolant   
					Level in Maintenance.   
					Coolant Temperature Gauge   
					Deck Lift Pedal   
					Located at the front of the left fuel tank.   
					Located at the right front corner of the floor pan.   
					The coolant temperature gauge monitors the   
					temperature of the engine coolant. An engine   
					overheating condition is indicated by the red area   
					on the gauge. An alarm will sound and the PTO   
					will disengage. Refer to the Warning Buzzer in the   
					Troubleshooting section.   
					Push the pedal forward with your foot to raise the   
					cutting deck. Allow the pedal to move rearward to   
					lower the cutting deck to the cut height that has been   
					set.   
					Pre-Start   
					Fill fuel tank on level ground.   
					Note: If the engine coolant level is below the   
					indicator line on the overflow bottle when the engine   
					is cold, the coolant temperature gauge may not   
					register correctly during operation. Refer to Check   
					Engine Coolant Level in Maintenance.   
					Make sure you understand the controls, their   
					locations, their functions, and their safety   
					requirements.   
					Voltmeter   
					Refer to the Maintenance section and perform all the   
					necessary inspection and maintenance steps.   
					Located next to the Coolant Temperature Gauge at   
					the front of the left fuel tank.   
					Determining Fuel   
					The voltmeter measure the voltage output of the   
					alternator. Both high and low voltages will potentially   
					damage the battery.   
					The engine runs on clean, fresh diesel fuel with   
					a minimum octane rating of 40. Purchase fuel in   
					quantities that can be used within 30 days to ensure   
					fuel freshness.   
					Glow Plug Switch and Light   
					Use summer grade diesel fuel (No. 2-D) at   
					temperatures above 20°F (-7°C) and winter grade   
					diesel fuel (No. 1-D or No. 1-D/2-D blend) below   
					20° F (-7° C). Use of winter grade diesel fuel at lower   
					temperatures provides lower flash point and pour   
					point characteristics, therefore easing startability and   
					lessening chances of chemical separation of the fuel   
					due to lower temperatures (wax appearance, which   
					may plug filters).   
					Located on the right fuel tank.   
					Depress and hold the switch to heat the glow plugs.   
					The glow plug light comes on when the glow plug   
					switch is depressed. The glow plug light indicates the   
					glow plugs are preheating the combustion chamber.   
					Low Oil Pressure Light   
					Located on the right fuel tank.   
					Use of summer grade diesel fuel above 20°F (-7°C)   
					will contribute toward longer life of the pump   
					components.   
					Light will come on when engine oil pressure is low   
					or lost.

				Operation   
					Important: Do Not use kerosene or gasoline   
					instead of diesel fuel. Failure to observe this   
					caution will damage the engine.   
					rear part of the seat is secured with the seat   
					latch.   
					Do Not overfill fuel tank. Fill the fuel tank to the   
					bottom of the filler neck. The empty space in the   
					tank allows the fuel to expand. Overfilling may result   
					in fuel leakage or damage to the engine or emission   
					system.   
					If possible, fill the fuel tank after each use. This will   
					minimize possible buildup of condensation inside the   
					fuel tank.   
					Biodiesel Ready   
					This machine can also use a biodiesel blended fuel   
					of up to B20 (20% biodiesel, 80% petrodiesel). The   
					petrodiesel portion should be low or ultra low sulfur.   
					Observe the following precautions:   
					• The biodiesel portion of the fuel meets   
					specification ASTM D6751 or EN14214.   
					• The blended fuel composition should meet   
					ASTM D975 or EN590.   
					Figure 6   
					• Painted surfaces may be damaged by biodiesel   
					blends.   
					1. Roll bar   
					2. Raised position   
					3. Pin   
					4. Hairpin cotter pin   
					• Use B5 (biodiesel content of 5%) or lesser blend   
					in cold weather.   
					Open the Fuel Shut-Off Valve   
					• Monitor seals, hoses, gaskets in contact with fuel   
					as they may degrade over time.   
					Turn the valve to the LH or RH tank.   
					• Fuel filter plugging maybe expected for a time   
					after converting to biodiesel blends.

					The cutting height of the mower deck is adjusted   
					from 1 to 5 inches (2.54 cm to 12.7 cm) in 1/4 inch   
					(6.4 mm) increments.   
					It is recommended to change the anti-scalp roller   
					position when the height of cut has changed.   
					1. Stop the machine and move the motion control   
					levers outward to the neutral locked position.

					mm) clearance to the ground to minimize gouging   
					and roller wear or damage.   
					Note: When changing the cutting height   
					positions, always come to a complete stop   
					and disengage the PTO.   
					Figure 11   
					For cutting heights above 4.0 inches (102 mm) use the   
					bottom hole. The rollers will still be effective against   
					scalping.

				Operation   
					7. Be sure the roller bolts are installed with the   
					spring disc washer between the head of the bolt   
					and the mounting bracket.   
					CAUTION   
					This unit does not have proper turn signals,   
					lights, reflective markings, or a slow moving   
					vehicle emblem. Driving on a street or roadway   
					without such equipment is dangerous and   
					can lead to accidents causing personal injury.   
					Driving on a street or roadway without such   
					equipment may also be a violation of State laws   
					and the operator may be subject to traffic tickets   
					and/or fines.   
					Note: The foot operated deck lift assist lever   
					can be used to momentarily lift the deck to clear   
					objects. Be sure that PTO is disengaged.   
					8. Torque the 3/8–24 x 2 Gr 8 hex capscrew to   
					
					Do Not drive a unit on a public street or roadway.   
					WARNING   
					Loading a unit on a trailer or truck increases   
					the possibility of backward tip-over. Backward   
					tip-over could cause serious injury or death.   
					• Use extreme caution when operating a unit   
					on a ramp.   
					• Use only a single, full width ramp; Do Not   
					use individual ramps for each side of the unit.   
					• If individual ramps must be used, use enough   
					ramps to create an unbroken ramp surface   
					wider than the unit.   
					Figure 12   
					1. Spring disc washer   
					(cone towards bolt head)   
					3. 3/8 nyloc-torque to 30-35   
					ft-lb (41-47 N-m)   
					• Do Not exceed a 15° angle between ramp and   
					ground or between ramp and trailer or truck.   
					• Avoid sudden acceleration while driving unit   
					up a ramp to avoid tipping backward.   
					2. Front right anti-scalp   
					bracket shown   
					4. 3/8-24 x 2 GR8 torque to   
					50-55 ft-lb (68-75 N-m)   
					• Avoid sudden deceleration while backing unit   
					down a ramp to avoid tipping backward.   
					9. If the 3/8 nyloc nut has been removed,   
					re-install and torque to 30–35 ft-lb (41–47 N-m)   
					
					Loading a Unit   
					Use extreme caution when loading units on trailers or   
					trucks. One full width ramp that is wide enough to   
					extend beyond the rear tires is recommended instead   
					of individual ramps for each side of the unit. The   
					lower rear section of the tractor frame extends back   
					between the rear wheels and serves as a stop for   
					tipping backward. Having a full width ramp provides   
					a surface for the frame members to contact if the   
					unit starts to tip backward. If it is not possible to use   
					one full width ramp, use enough individual ramps to   
					simulate a full width continuous ramp.   
					Transporting   
					Transporting a Unit   
					Use a heavy-duty trailer or truck to transport the   
					machine. Lock brake and block wheels. Securely   
					fasten the machine to the trailer or truck with straps,   
					chains, cable, or ropes. Be sure that the trailer or truck   
					has all necessary lighting and marking as required by   
					law. Secure a trailer with a safety chain.   
					Ramp should be long enough so that the angles   
					between the ramp and the ground and the ramp and   
					the trailer or truck Do Not exceed 15°. A steeper   
					angle may cause mower deck components to get   
					caught as the unit moves from ramp to trailer or

				Operation   
					truck. Steeper angles may also cause the unit to tip   
					backward. If loading on or near a slope, position   
					the trailer or truck so it is on the down side of the   
					slope and the ramp extends up the slope. This will   
					minimize the ramp angle. The trailer or truck should   
					be as level as possible.   
					Important: Do Not attempt to turn the unit   
					while on the ramp, you may lose control and   
					drive off the side.   
					Avoid sudden acceleration when driving up a ramp   
					and sudden deceleration when backing down a ramp.   
					Both maneuvers can cause the unit to tip backward.

					Removing the Shim:   
					1. Stop engine, wait for all moving parts to stop,   
					and remove key. Engage parking brake. Allow   
					the machine to cool completely before starting   
					these instructions.   
					E. Using a 0.010 inch thick feeler gauge, verify   
					that a gap is present between the rotor and   
					armature face on both sides of the brake pole   
					as shown. (Due to the way the rotor and   
					armature faces wear (peaks and valleys) it is   
					sometimes difficult to measure the true gap.)   
					2. Using a pneumatic line, blow out any debris   
					from under the brake pole and around the brake   
					spacers.   
					3. Check the condition of the wire harness leads,   
					connectors, and terminals. Clean or repair as   
					necessary.   
					4. Verify that 12V is present at the clutch connector   
					when the PTO switch is engaged.

					Figure 25   
					1. Feeler gauge   
					A. Loosen both brake mounting bolts one-half   
					
					Note: Do Not remove the brake pole from   
					the field shell/armature. The brake pole has   
					worn to match the armature and needs to   
					continue to match after the shim is removed   
					to ensure proper brake torque.
