„ Turn each adjustment nut 1/4 turn clockwise, then try
again to push the mower.
After final adjustment, test the brakes by driving the mower
at normal speed on flat ground to be sure the mower stops
quickly when the brake pedal is depressed.
LEVELING THE CUTTING DECK
See Figures 20 - 21.
If your lawn appears unevenly cut after using the mower,
the cutting deck may need adjusting. Before deciding that
leveling the cutting deck is necessary, make sure tires are
properly inflated to the recommended PSI when mowing.
Over- or under-inflated tires can affect the appearance of
the cut, and proper inflation of the tires may be all that is
needed to resolve uneven cutting issues.
NOTE: Always check side-to-side alignment and adjust as
needed before measuring and adjusting front to back.
Before beginning:
„ Move the mower to a level surface. Make sure to set the
parking brake and blade engage knob is down.
„ Stop the motor and remove the start key.
„ Lower the height of the cutting deck to its lowest position.
„ Check that tires are inflated to the recommended PSI.
Refer to Tire Maintenance section.
To make side-to-side adjustment:
„ Position the blades so that the ends point toward the
sides of the mower.
„ On the outside edge of each blade, measure the distance
from the bottom edge of the side of the blade to the
ground. If the distance between the two sides is greater
than 1/8 in., a side-to-side adjustment is necessary.
„ On the side you wish to adjust, loosen the jam nuts as
shown.
„ Turn the adjustment nuts clockwise to raise or counter-
clockwise to lower the side of the cutting deck. Each full
turn of the adjustment nut will change the deck height
approximately 1/8 in.
„ Measure again. Continue to adjust and measure until
the difference between the distance on each side is 1/8
in. or less.
„ Proceed to front-to-back adjustment.
To make front-to-back adjustment:
NOTE: Always level the deck side to side before making a
front to back adjustment.
„ Position the blade nearest the side discharge chute so
that the ends now point toward the front and back of
the mower.
„ Measure the distance from the tip of the blade to the
ground. For best results, the front tip of the blade should
be from 1/4 in. to 1/2 in. lower than the rear tip.
MAINTENANCE
ADJUSTMENT
„ If front-to-back adjustment is needed, turn the adjustment
nut clockwise to raise or counterclockwise to lower the
back of the cutting deck. Each full turn of the adjustment
nut will change the deck height approximately 1/8 in.
„ Measure again to verify the front tip is now 1/4 in. to
1/2 in. lower than the rear tip. If not, continue to adjust
and measure until they are.
NOTE: Deck levelness is factory set and not required as
a regular maintenance item.
REPLACING THE BATTERIES
See Figures 22 - 23.
NOTE: Only use RYOBI Electric Riding Lawn Mower 80 volt
lithium batteries.
This mower can operate on up to three 80 volt battery packs.
The system automatically balances the load between them
during discharge.
NOTE: Used lithium batteries should always be recycled.
Always abide by the safety warnings provided with the bat-
tery packs. Dispose of old batteries according to local and
state regulations.
„ Move the mower to a level surface. Make sure to set the
parking brake and blade engage knob is down.
„ Stop the motor and remove the start key.
When removing/replacing an 80 volt battery pack:
„ Pull up on latch to lift tractor hood.
„ Remove the storage tray.
„ Disconnect the battery pack's quick-connect plug by
squeezing the tabs, releasing it from the battery pack,
