Batteries contain sulfuric acid. Avoid
contact with skin, eyes and clothing.
Batteries produce a highly explosive
hydrogen gas while being charged.
Always keep cigarettes, sparks, open
flame and other sources of ignition
away from battery. Always shield
eyes and face from battery. In the
event of accident, flush with water and
call a physician immediately. Keep
batteries and acid out of the reach of
children.
CHECKING DRIVE SYSTEM FLUID
LEVEL
Check fluid level in the reservoir, located under
the seat, with the engine turned off. This is the
fluid reservoir for both hydro pumps and wheel
motors. If fluid is required, add until level is equal
to the full mark on the reservoir decal (shown be-
low). Use Grasshopper Fluid (Grasshopper part
no. 345050 for 1 quart [.94 l] container).
CHANGING DRIVE SYSTEM FLUID
AND FILTERS
Change fluid filter, mounted on the panel under
the seat, every 1000 hours of use. Change fluid
every 1000 hours of use. To change fluid, loosen
PTO shield (item 14, page 41) and remove Trash
Screen (item 57, page 31). Remove Spring
Clamp (item 16, page 39) and hose (item 14, 15)
from the bottom of each hydro. Use .25" allen
wrench to also remove screw (located behind
item 12 fitting, page 39) from each hydro casing.
Allow oil to drain completely. Refill the reservoir
with approximately 2 quarts (1.89 l) of fluid of the
type and viscosity as prescribed in the previous
section. Run engine and check for leaks. Stop
engine and check the fluid level in the reservoir
and add fluid as needed.
Note: No air bleeding is necessary since the
system is self bleeding.
