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
Battery acid is caustic and fumes
are explosive and can cause serious injury or death.
Use insulated tools, wear protective glasses or
goggles and protective clothing when working with
batteries. Read and obey the battery manufacturer’s
instructions.
Be certain the ignition switch is “OFF” and the key
has been removed before servicing the battery.
1. Verify battery polarity before connecting or
disconnecting the battery cables.
2. When installing the battery, always assemble the
RED, positive ( + ) battery cable first and the
ground, BLACK, negative ( - ) cable last.
3. When removing the battery, always remove the
ground, negative ( - ) cable first and the red,
positive ( + ) cable last.
8
4. Check the electrolyte level every 100 hours of
operation.
5. Clean the cable ends and battery posts with steel
wool. Use a solution of baking soda and water to
clean the battery. Do not allow the solution to
enter into the battery cells.
6. Tighten cables securely to battery terminals and
apply a light coat of silicone dielectric grease to
terminals and cable ends to prevent corrosion.
Keep terminal covers in place.
MAINTENANCE

HYDRAULIC SYSTEM
Fluid level in the hydraulic system should be
checked after the first 5 hours of operation, and
every 100 hours thereafter, 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
View from right side
AFTER FIRST FIVE (5) HOURS
1. Remove plug N to 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:
View from below machine
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.

FUEL SYSTEM
Before attempting to service any
part of the fuel system, the pressure must be
relieved.
Refer to section 5B of the engine manual.
A low pressure filter C is located on the kickplate as
shown. Inspect at every oil change and replace
when necessary.
A high pressure fuel filter S is located as shown. The
fuel in this filter is always under pressure. The filter
should be replaced every 1500 hours of operation.
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. The procedure
for obtaining MIL codes and what they indicate may be found in the engine manufacturer’s service
manual.
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.

BLADE REMOVAL
BLADE BALANCE
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 A as 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.
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.
3. Install assembly on the blade spindle.
4. Torque the blade bolt to 70 ft-lbs.
SHARPENING
Blades may be 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.

NOTES:
–
Height of cut may vary due to the amount of
tread on the tires, tire diameter or inflation
pressure.
–
For best results, adjust the rear deck rollers for
the height of cut to be used (see below).
REAR DECK ROLLERS
The rear outside deck rollers are adjustable up and
down to provide improved deck flotation and scalping
protection at various heights of cut. They are not
intended to ride continuously on the ground. Adjust
no closer than 3/8" (10mm) to the ground.
Height of cut ranges for roller adjustment
PUSH ARMS
The push arm rod ends must be adjusted evenly to:
–
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

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 A by
loosening the nut B on the idler rod C.

ADJUSTMENTS
HYDROSTAT ADJUSTMENTS
A turnbuckle-style hydrostat neutral adjustment is
provided.
Neutral:
1. Support the machine with the rear wheels off the
ground. Use jackstands or equivalent support.
Do not rely only on mechanical or hydraulic jacks.
2. Move the traction levers out into the neutral lock
position and raise the seat.
3. Disconnect the seat switch and temporarily
connect the two terminals with jumper wire J as
shown.
4. Start the engine and run at low speed.
5. Loosen jam nuts T at both ends of the
turnbuckle.
6. Rotate the turnbuckle until the corresponding
wheel stops turning. Lock the turnbuckle jam
nuts. Run the engine up to high idle to check the
adjustment. Readjust if necessary.
7. Repeat steps 5 and 6 for the opposite side.
8. Remove the jumper wire and reconnect the seat
switch.
Reverse Return:
1. Move traction levers out to the neutral lock
position and raise the seat.
2. Locknut U should be run on the bolt as far as it
will go.
Right side adjustments
(wiring harness and seat rod removed for clarity)
3. Loosen jam nut Y. Adjust the clevis yoke by
turning the head of the bolt until the clevis pin just
makes contact with the rear of the slot in the
lever it connects with. Tighten jam nut Y.
4. Repeat steps 2 and 3 for the opposite side.
NOTE: A slight creep in reverse is acceptable
provided the wheel does not turn and the hydrostat
pump does not whine when the parking brake is on.

BELT REPLACEMENT
BZT 2000
EFI Series
Note: Always use Bunton replacement belts, not general purpose belts. Bunton belts are
specially designed for use on commercial mowers and will normally last longer.
ENGINE-CUTTERDECK (PTO) BELT
1. Set the cutterdeck in the lowest height-of-cut
position.
2. Attach a short extension to a 3/8" drive ratchet.
Insert the ratchet extension into the square hole
in the idler arm and use the ratchet to rotate the
idler assembly enough to remove the belt.
Remove the belt from the idlers and center
cutterdeck pulley. Push belt back under engine
deck.
3. Disconnect the electric clutch from the wire
harness at plug P.
4. Remove the carriage bolts securing torque
restraint Q to clutch R. Remove torque restraint.
5. Remove old belt from the machine.
6. Install a new belt by performing the these steps in
reverse order.
PUMP-DRIVE BELT
1. Remove engine-cutterdeck belt (see engine-cutterdeck belt replacement).
2. Attach an extension to a 3/8" drive ratchet. Insert the ratchet extension in the square hole of the pump
drive idler arm. Use the ratchet handle to rotate it enough to remove the pump drive belt.
3. Install a new pump drive belt in the same manner as it was removed.
4. Re-install engine-cutterdeck belt (see engine-cutterdeck belt replacement).

4. Install the new belt by performing these steps in
reverse order. Take care to get the new belt on
the correct side of the belt guides.
5. Re-install engine-cutterdeck belt (see enginecutterdeck belt replacement).
72" CUTTERDECK BELT
Before removing the cutterdeck belt, the engine to
cutterdeck (pto) belt must be removed from the
center pulley.
1. Decrease the tension on the idler pulley A by
loosening the nut B on the idler rod C.
2. Replace the belt on the engine to cutterdeck and
replace the tension.

INTERLOCK SYSTEM:
Start: The PTO (blades) must be off, traction levers
in neutral lock, and parking brake on for engine to
crank.
Run: Operator must be in seat to take parking brake
off, to move traction levers out of the neutral lock
position, or to turn the PTO (blades) on or the engine
will kill. The parking brake must be off for the traction
levers to move out of the neutral lock position.
