Walker Mowers are shipped partially assembled to
our distribution network. These steps should be
completed before the customer takes possession
of their new mower.
Assembling the Tractor
The following steps need to be performed to pre-
pare the R21 for initial use after shipment from the
factory.
1. Install the Seat.
A. Remove the protective sheet from the seat
panel.
A. Install the seat using the four (4) 1-1/4 x
3/4 Shock Mounts and 5/16-18 Whiz Lock-
nuts supplied on the bottom of the seat.
B. Connect the safety switch wire harness to
the receptacle on the bottom of the seat.
2. Install the steering lever handles. The steer-
ing level handles and necessary hardware are
included in the hardware bag. Attach each
handle using two (2) 1/4-20 x .770 Knurled

3. The tires ship installed. Check and adjust the
ination of the tires. The tire ination recom-
mendations are:
Drive = 15 PSI (103 kPa)
Tailwheel = 20 PSI (137 kPa)
For tractors shipping outside the US the following
additional steps will need to be performed.
4. Add fuel to the gas tank. Use only clean, fresh
automotive grade unleaded gasoline (87 oc-
tane minimum, 10% ethanol maximum).
IMPORTANT: DO NOT permit dirt or other
foreign matter to enter the fuel tank. Wipe dirt
from around the ller cap before removing.
Use a clean fuel storage container and funnel.
IMPORTANT: DO NOT mix oil with gasoline.
Always use fresh, automotive grade unleaded
gasoline. DO NOT use gasoline containing
greater than 10% ethanol. DO NOT use ad-
ditives, such as carburetor cleaners, deicers,
or moisture removing agents. DO NOT use
gasoline blended with methyl alcohol.
DANGER
Handle gasoline with care. Gasoline is
highly ammable and its vapors are explo-
sive. Use safe refueling procedures:
● DO NOT smoke while refueling.
● Avoid spilling fuel; use a funnel or spout.
