HYDRAULIC FLUID FILTER CANISTER
REPLACEMENT
Refer to the “Hydraulic Fluid and Hydraulic Filter
Service Schedule” table for filter replacement schedule
times. Order Turfco part number 661572. Be sure to
replace the filter with an “absolute” 10 micron filter. An
“absolute” filter removes up to 98% of the 10 micron
or larger particles, while a 10 micron “nominal” filter
removes only 17% of 10 micron or larger particles.
HYDRAULIC FLUID TANK
The tank is mounted to the right front of the top dresser.
Capacity of the tank is 34 liters (9 gallons). Use the
dipstick on the end of the filler cap to measure the
amount of hydraulic fluid in the tank. Measure when the
pump and engine are not running. Do not overfill the
tank, room has been allowed for the expansion of the
fluid as it heats during use.
The filler tube has an internal strainer basket to filter
out larger sized impurities in the fluid during filling of the
tank. Use caution during filling not to damage or tear the
strainer screen with long filler can nozzles. To service or
clean out the strainer, the entire filler assembly needs
be removed from the tank. The filler cap also acts as a
breather vent for the tank. The breather is necessary to
allow for pressure relief of the hydraulic system during
operation. Do not block the breather or replace the filler
cap with a cap that is not vented or capable of filtering
out dirt or dust (40 micron minimum). Always clean the
area around the filler before removing the cap.
