Check Transmission Fluid; Check Hydraulic Fluid - Toro Reelmaster 5500-D Service Manual

Check Transmission Fluid

The front axle housing acts as the reservoir for the trans-
mission. The transmission and axle housing hold about
5 quarts (4.7 L) of Mobil 424 hydraulic fluid. Check level
of transmission oil daily.
1. Position machine on a level surface, lower cutting
units, and stop the engine.
2. Remove floor panel.
3. Unscrew dipstick cap from the transmission filler
neck; wipe it with a clean rag. Screw dipstick into filler
neck. Remove dipstick and check level of oil. If level is
not within 1/2 inch (1.3 cm) from the groove in the dip-
stick, add enough oil to raise the level to the groove
mark. Do not overfill by more than 1/4 inch (0.6 cm)
above the groove.
4. Screw dipstick filler cap finger-tight onto filler neck.
It is not necessary to tighten cap with a wrench.

Check Hydraulic Fluid

The hydraulic system driving the reels is designed to op-
erate on anti-wear hydraulic fluid. The reservoir holds
about 8.5 gallons (32 L) hydraulic fluid. Check level of
hydraulic fluid daily.
1. Position machine on a level surface, lower the cut-
ting units and stop the engine.
2. Clean area around filler neck and cap of hydraulic
reservoir. Remove cap from filler neck.
3. Remove dipstick from filler neck and wipe it with a
clean rag. Insert dipstick into filler neck; then remove it
and check level of fluid. Fluid level should be within 1/4
inch (0.6 cm) of the mark on dipstick.
4. If level is low, add appropriate fluid to raise level to full
mark
5. Install dipstick and cap onto filler neck.
IMPORTANT: Two groups of hydraulic fluid are spe-
cified to allow optimal operation of the machine in
a wide range of temperatures encountered. The
Group 1 fluids are a multi-viscosity hydraulic fluids
that allow operation at lower temperatures without
increased viscosity, which is associated with
straight viscosity fluids.
Using the Mobil 424 type fluids in the higher ambient
temperatures may result in decreased efficiency in
some of the hydraulic components compared to using
the Mobil DTE 26 type fluids.

The Mobil DTE 26 type fluids are straight viscosity fluids
which remain slightly more viscous at higher tempera-
tures than the multi-viscosity fluids.
Using the Mobil DTE 26 type fluids in the lower ambient
temperatures may result in harder starting, increased
engine laboring while cold, sluggish or non-operating
valve spools while cold and increase filter back pressure
due to the higher fluid viscosity.
It is recommended that you select which set of condi-
tions, either ambient temperatures above 70_ F (21_ C).
or below 100_ F (38_
throughout the year, rather than changing fluid types
several times per year.
