MAINTENANCE
CHECK DAILY
Operator Presence Interlock System - Start Operation
For the engine to crank, the parking brake must be on, the PTO (blades) off and traction levers in the neutral
lock position. Sit in the seat and check, one by one, if the engine will crank with the parking brake off, the
blades on, and either traction lever out of neutral lock. Also, make sure engine coolant temperature gauge
light flashes upon turning key to the ON position.
Operator Presence Interlock System - Run Operation
The operator must be in the seat for the engine to run with the parking brake off, the traction levers moved out
of the neutral lock position, or the blades on. To check:
1. Start the engine and run at 1/2 throttle with the operator on the machine but raised off the seat.
2. One by one: move the parking brake to the “OFF” position, traction levers out of the neutral lock position
(check each independently), and turn the blades on. Each check should kill the engine after 1/2 second.
(A 1/2 second delay is built into the system to prevent engine cutout when traversing rough terrain.)
Repair machine before using if the Operator Presence Interlock System does not operate correctly in start or
run. Contact your authorized Bunton dealer.
Hardware
Tighten any nuts and bolts found loose. Replace any broken or missing cotter pins. Repair any other problems
before operating.
Tire pressure
Tires should be kept inflated at 14 lbs/in2(1.0 kg/cm2). Improper tire inflation can cause rapid tire wear and
poor traction. Uneven inflation can cause uneven cutting.
Battery
Check the electrolyte level at each oil change as follows:
1. Stop engine and remove key.
2. Remove battery vent caps. The electrolyte level should reach the bottom of the vents.
3. Top up, if necessary, with distilled water.
4. Replace vent caps.
Engine Malfunction Indicator Lamp
The ECU is the brain or central processing computer of the entire EFI fuel/ignition management system. If
a fault is detected, the ECU turns on the Malfunction Indicator Light (MIL) on the equipment control panel,
stores the fault code in its fault memory, and goes into a default operating mode.
NOTE: When the key is first turned on, the light comes on for several seconds (or until the engine starts)
to verify the light is working.

1. Push arms (2 points located at rear of cutterdeck under each fuel tank)
2. Brake lever pivot (1 point)
3. Deck idler pivot bearings (2 points)
4. Deck lift pivots (6 points)
5. Hydro belt tensioner (1 point under engine deck)
6. Caster wheel pivots (2 points)
(Lubricate every 500 hours or once a year)
NOTE ON BLADE SPINDLES -The blade spindles on these machines use a
superior sealed bearing that does not require relubrication.

MAINTENANCE
HYDRAULIC SYSTEM
After the first 5 hours of operation, fluid level in the
hydraulic system should be checked every 100 hours
or when a leak has occurred. If the fluid is low, check
all components for leaks.
To check, remove reservoir cap M. The fluid level
should be at the bottom of the filler tube. If low, top up
(do not overfill). Use one of the oils listed below:
– SAE 15W40 motor oil
– SAE 20W50 motor oil
– 15W50 synthetic motor oil
AFTER FIRST FIVE (5) HOURS
1. Remove plug Nto drain hydraulic reservoir.
Dispose of used oil in accordance with local
requirements.
2. Clean and replace the plug.
3. Change hydraulic oil filter G.
4. Fill the reservoir with fresh oil to the bottom of the
reservoir filler tube, using an oil from the list
above. Do not overfill.
PERIODIC OIL CHANGES
Change the hydraulic fluid and hydraulic filter after
each 500 hours of operation using the same
procedure given above.
NOTES:
Before servicing the hydraulic system, stop the engine, disconnect spark plug wires and disengage the PTO.
– After any hydraulic line is opened, plug or cap it promptly to reduce the risk of contamination.
– Do not use teflon tape on hydraulic pipe fittings. Use a liquid sealant that will dissolve into the system.
– Make sure all hydraulic connections are tight and hydraulic hoses and lines are in good condition before
applying pressure to system.
The machine's hydraulic system operates under high pressure. When checking for leaks, do not use your
hands to attempt to find a leak. Instead, use cardboard or paper. Escaping hydraulic fluid can be under
sufficient pressure to penetrate skin and cause serious injury. If hydraulic fluid is injected into the skin, it must
be promptly removed by a doctor familiar with this form of injury or gangrene may result.

MAINTENANCE
SPARK PLUGS
Remove each plug and check condition.
– Good operating conditions are indicated if the plug has a light coating of grey or tan deposit.
– A white blistered coating indicates overheating. A black coating indicates an “over rich” fuel mixture. Both
may be caused by a clogged air cleaner or improper carburetor adjustment.
– Do not sandblast, wire brush or otherwise attempt to repair a plug in poor condition. Best results are
obtained with a new plug.
– Set plug gap as specified in engine manual..
ENGINE OIL
Do not perform engine maintenance without the
engine off, spark plug wires disconnected and PTO
disengaged.
AFTER FIRST FIVE (5) HOURS
While the engine is warm:

MAINTENANCE
BLADE REMOVAL
Follow these instructions to prevent injury during
blade removal:
1. Loosen with a box wrench or a socket and long
breaker bar. To gain additional leverage, slip a
long pipe or thick-walled tube over breaker bar or
wrench.
2. Insert wood block Aas shown, with grain
perpendicular to blade, to prevent blade from
turning when loosening.
3. Wear thickly padded gloves. Keep hands clear of
blade path. Blades may rotate when bolt releases.
SHARPENING
Blades may sharpened by filing or grinding.
–Inspect blades before sharpening.
–Replace bent or cracked blades.
–Replace blades when the lift portion has worn
thin.
–Maintain cut angle at 30o.
–Do not overheat blades when sharpening.
–Always use Bunton blades. Use of another
manufacturer’s blades may be dangerous.
BLADE BALANCE
Blade balance must be maintained at 5/8 oz-in (19.4
g-cm) or less. Failure to keep blades balanced
causes excess vibration, wear, and shortened life of
most components of the machine.
To balance a blade:
1. Sharpen blade first.
2. Balance the blade at the center.
3. Attach a 1/8 oz (3.9 g) weight at a distance 5"
(127 mm) from center on the light end. This
should make the light end the heavy end:
– If it does, the blade is balanced.
– If does not, file or grind the heavy end until
the addition of the weight makes the light end
the heavy end.
BLADE INSTALLATION
1. Wear thickly padded gloves to prevent cuts from
the sharp blade.
2. Insert the blade bolt, in order, through the conical
washer (cup side toward the blade, as shown),
the blade, and the blade spacer.

– locate the deck perpendicular to the front-to-rear
axis of the machine; and
– so the notch at the front of the engine deck clears
the push arm bracket on the rear of the
cutterdeck when the cutterdeck is raised to the
transport position.
Adjust the rod end length to 1-7/16" (37 mm) to start.
If any additional adjustment is required, adjust both
rod ends so the same number of threads show.
BELT TENSION
All belts are tensioned by spring loaded idlers and do
not require any adjustment, except the spring loaded
72" cutterdeck belt. Manual tension adjustment of
the spring loaded 72" cutterdeck belt is as follows.
A single belt supplies power to the three blade
spindles. Belt tension is maintained by a spring D
loaded idler pulley. Proper belt tension is maintained
with a minimum spring dimension of 3-7/8” (77mm).
Keep this area clean and periodically inspect the
cutterdeck belt for abnormal wear and proper tension.
If the cutterdeck belt becomes worn, damaged, or
stretched beyond use; Replace it.
Before removing the cutterdeck belt, the engine to
cutterdeck (pto) belt must be removed from the
center pulley.
1. Remove tension on the engine to cutterdeck belt at
the engine and remove the belt from the deck pulley.
2. Decrease the tension on the idler pulley Aby
loosening the nut Bon the idler rod C.
