the seat belt when the ROPS is in the raised position.
If the ROPS must be lowered for clearance, return ROPS
to raised position when clearance is no longer required.
NEVER use the seat belt when the ROPS is in the lowered
position. If the ROPS is lowered for transportation, return
it to the raised position before operating the machine.
WARNING
54ZB, 62ZB
ALWAYS use the seat belt when the ROPS is in the
raised position. Failure to do so could result in serious
injury or death in the event of a rollover. NEVER use the
seat belt with the ROPS in the lowered position.
Lowering ROPS
If additional clearance is needed the ROPS may be
lowered. Lower the ROPS using the following steps:
1. Remove the two retaining pins.
2. Place the ROPS in the lowered position.
3. Insert the pins into the lowered position holes.
NEVER use the seatbelt when the ROPS is in the lowered

push the mower away from the spill and wipe up
immediately.
Refer to the Engine Owner’s Manual for the type of fuel
to use.
A fuel shut off valve is located on the bottom of the fuel
tank. It is recommended that the fuel be shut off when
transporting between job sites and when storing the
mower for extended periods of time.
CAUTION
CAUTION! Before making any adjustments to and/or
servicing your BEAST mower, make sure the mower is on a
level surface, with the ignition switch off, the key
removed, the brake set, and the blades disengaged. Also,
disconnect the spark plug wires from the spark plugs and
ground them against the engine to prevent inadvertent
starting.
If you are performing adjustments or maintenance after
operating the mower, allow the unit to cool and always
wear protective clothing.
Tire Pressure
Incorrect tire pressure may cause the mower to pull to one
side and/or result in an uneven cut. Use caution when filling
the tires. NEVER exceed the recommended maximum tire
pressure as stated on the tires.
Air Filter
Refer to the Engine Owner’s Manual for the
recommended maintenance.
Engine Oil
CHECK ENGINE OIL BEFORE EACH USE. Refer to the Engine
Owner’s Manual for the type of oil to use, oil change
intervals, and the proper procedures to check and change
oil.
Blades
Inspect blades on a daily basis for nicks, bends, and
excessive wear. If the blades are worn, cracked, bent, or
damaged, replace them before using the mower. Choose
genuine BEAST mower replacement blades to ensure quality and performance. (See page 23 for blade removal instructions.)
When sharpening the blades, sharpen only the cutting
edges and try to maintain the original angle of the blade. Do
not make the cutting edge razor sharp. Remove the same
amount from each end of the blade so that balance is
maintained.
CAUTION: Always wear work gloves when performing
blade maintenance and beware of the cutting edges. Be
sure the engine is off, the key removed, and the spark
plug wires are disconnected from the spark plugs to
prevent inadvertent starting.

Spindle Brake Inspection and Replacement
IMPORTANT! The mower belts are adjusted to ensure
the blades stop turning within seven (7) seconds of
releasing the blade control lever. If you are making any
belt adjustments whatsoever, for your safety and the
safety of others around you, you must ensure the belts
are re-adjusted to achieve this design specification.
Blade and pulley brake inspections should be
performed every 100 blade on and off cycles.
Before beginning service, park the mower on a level
surface, turn the blades off, turn the engine off, set the
brake, take the key out of the switch, wait an adequate
time to make certain no blades are turning, and remove
spark plug wires from spark plugs.
1. Engage the blade handle (make certain the engine
cannot start) to pull the brakes off of the pulleys.
2. Remove the pulley guards from the deck.
3. Visually inspect the brake pads for wear. Make
certain that no metal is touching the pulleys.
4. The brake pad material should be approximately 1/8inch thick. Replace the brakes if the material is less
than 1/16-inch thick.
Note: Replacing all brake pads is recommended if
replacement of one brake is required.
5. To replace the brake, use a pair of pliers to remove
the springs.
6. Remove the two mounting bolts and
disconnect the spring from the cable.
7. Discard all of these parts. DO NOT reuse springs.
New brakes are equipped with new springs for proper
braking.
8. Install the new brakes by reversing the procedure in
steps 5 and 6.
9. Disengage the blade handle and inspect the brake
contact surface. All of the brake pad contacting
material should be contacting the bottom of the pulley.
Note: Springs may vary from those pictured based on
the particular application.
Removing the Blades
Required tools: Two (2) 15/16” box end wrenches
1. Park the mower on level ground, set the brake and block
the rear wheels to prevent accidental rollback.
2. Raise the front end of the mower and place on a jack
stand.
CAUTION! Beware of the cutting edges on the blades. The rotation
of one blade may cause the other blades to rotate. Always wear
work gloves when handling blades.
3. Use one wrench to loosen nut A while holding bolt B
with the other wrench (see photo).
CAUTION
A
B
4. Slide the blade bolt down through the mower deck and
out.
5. To reinstall, insert the blade bolt through the cutting
deck.
6. Install the blade spacers that were removed back onto
the blade bolt followed by the nut and tighten. (See
figure below.)
IMPORTANT: The number of spacers should always be
the same on each blade bolt. NEVER put the spacers below
the blade and NEVER straighten or weld the blades.

Engine-to-Hydraulic Drives Belt
Adjustment (Hydraulic drive Input
Belt)
The hydraulic drive input belt is
located underneath the chassis at
the rear of the mower. The belt
should move approximately 1/8 to
3/16-inch with three (3) to five (5)
pounds of pressure applied to the
belt midway between the hydraulic
drive pulleys when initially installed.
After approximately 1 hour of
running time, verify that the belt
tension is still correct and tighten if
necessary
Important: Do not over-tighten the
belt.
To adjust the belt, turn the nut on
the threaded tension rod found on
the right, rear corner of the mower.
Do not over-tighten. This could
cause damage to the hydraulic drive
systems.
The hydraulic drive input belt is an
8PK 1690 multi ribbed v belt. GXi part

Hydraulic Drive System Adjustment
The hydraulic drives are coupled to the final drives with a multi-v belt. Occasional re-tensioning of the belt may be
necessary. If performance decreases or hydraulic drive control handles are activated and the wheels do not turn,
inspect the multi-v belt. Before beginning the following test, read all warnings in this manual. If you are
uncomfortable with this procedure please contact GXi to be set up for service.
Normal service interval: seasonally or every 100 hrs.
Adjust the hydraulic drive adjustment bolts by tightening the two large 21mm nuts on the rear of the mower. Tighten
the final drive belt so there is approximately 3/4” belt deflection in the center of the belt with about 10lbs of pressure
applied.
The next step is to perform a “wall test.” Drive the mower against a padded
stationary object. For accurate results, a smooth brushed concrete surface
works best. Stand next to the mower with one hand on the seat. Start the
mower with one hand on the seat to engage the safety switch. Engage the
left side handle into the drive position. Quickly move the handle to full
forward position for about half a second. Now perform the same procedure
on the right side. If the belt squeals and the wheel does not spin on either
side, tighten each adjustment bolt one half turn. Always turn both bolts the
same amount whenever adjustment is required. Repeat the test until both
tires will break traction and spin.
Once you have the tension set so each wheel will just barely break traction,
mark the bolt on one side of the hex head as shown. Now tighten the bolt
(turn clockwise) one sixth of a turn. This will set tension so the belt does not
squeal, and provides ample torque for driving and mowing without causing
belt or hydraulic drive damage.
Now drive the mower on a grassy surface. Perform several Zero Turns. Drive the unit aggressively. If the
performance is “sloppy” or you have excessive belt chirping, tighten the bolt 1/6th of a rotation and re-test.
Re-Install the adjustment bolt retainer clips after adjustments.
If the mower is too nimble, or you want to reduce the power output to prevent damage to the turf, loosen the bolt
1/6th of a rotation and re-test. Occasional belt chirping is permitted. If the belt squeals excessively tighten 1/6th of a
rotation and re-test.

Lubrication
To ensure proper lubrication of moving parts, GXi
recommends that you lubricate the following components
with a high-quality, EP2 high-temperature-based grease or
equivalent. Should the conditions of operation be more
severe than normal, the lubrication interval may need to be
shortened. GTR/OPE grease is the recommended lubricant.
Lubrication Point Locations
54-inch & 62-inch mowers have 10 lubrication points.
Lubricate after every 50 hours of usage
1. Front wheels (2 locations, 1 on each wheel shaft)
2. Spindles (3 locations on 54-inch & 62-inch mower
decks).
Note: The lower spindle bearing is sealed on the bottom
and open on the top. The upper spindle bearing is sealed on
both sides. Failure to frequently replenish grease will cause
premature lower bearing failure. Frequent application of
grease to this bearing is critical to achieving long spindle
life in harsh duty environments.
3. Mower deck clutch pulley pivot.
Changing Battery
When disconnecting the battery make sure to
disconnect the negative terminal first and the positive
last. When reconnecting, connect the positive first and
the negative last.
