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 or retighten jam
nuts to secure.
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.
If front-to-back adjustment is needed, turn the adjustment
nuts 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.
NOTE: Make sure to turn the adjustment nuts on both
sides equally to prevent throwing the side-to-side mea-
surement off again.
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 27 - 30.
NOTE: Only use RYOBI Electric Riding Lawn Mower 80 volt
and 40 volt lithium batteries.
This mower can operate on up to two 80 volt battery packs.
There are two additional 40 volt battery ports that can help
extend the run time of the zero turn mower. The 80 volt bat-
teries are used first and the system automatically balances
the load between them during discharge. Any 40 volt batteries
inserted will extend the run time by adding additional energy
as the 80V batteries start to reach a lower state of charge.
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.
Park the mower on a level surface and set the parking
brake. Place the joystick in the locked neutral position,
stop the motor, and remove the start key.
Adjust the seat all the way forward.
When removing/replacing an 80 volt battery pack:
Press the center edge on the battery compartment cover
to release the latch. The cover will raise to gain access
to the compartment below.
