Procedure for Reel Motor Case Drain Test:
NOTE: Over a period of time, a reel motor can wear in-
ternally. A worn motor may by–pass oil to its case drain
causing the motor to be less efficient. Eventually,
enough oil loss will cause the reel motor to stall under
heavy cutting conditions. Continued operation with a
worn, inefficient motor can generate excessive heat,
cause damage to seals and other components in the hy-
draulic system, and affect quality of cut.
NOTE: One way to find a possibly bad reel motor is to
have another person observe the machine while mow-
ing in dense turf. A bad motor will run slower, produce
fewer clippings, and may cause marcelling (or a wash-
board appearance) on the turf.
1. Make sure hydraulic oil is at normal operating tem-
perature by operating the machine for approximately 10
minutes. Make sure the hydraulic tank is full.
2. Park machine on a level surface with the cutting units
lowered. Make sure engine is off and the parking brake
is engaged.
3. Read Precautions For Hydraulic Testing.
CAUTION
Operate all hydraulic controls to relieve system
pressure and avoid injury from pressurized hy-
draulic oil.

4. On the suspected bad reel motor, clean hose con-
nection and disconnect return hose from motor to man-
ifold (see table).
IMPORTANT: Make sure oil flow indicator arrow on
the flow gauge is showing that the oil will flow from
the motor through the tester and into the hose.

5. Install flow tester with pressure gauges in series with
the motor and the disconnected return hose. Make sure
the flow control valve on the tester is fully open.
6. Make sure backlap knob on the valve block is in the
mow position.
7. Clean hose fitting and disconnect case drain hose
from the manifold block (see table). Plug the manifold
port.
8. One person should sit on the seat and operate the
machine while another person holds the hose and reads
the tester. Start engine and move the throttle to full
speed (3200 + 50 RPM).
9. Engage cutting units by pulling the reel engage knob
on the instrument panel out. While watching pressure
gauges, slowly close flow control valve until a pressure
of 1200 PSI is obtained.
10.Collect hydraulic fluid for 15 seconds by putting case
drain hose into 1 quart container graduated in ounces (1
liter container graduated in milliliters).
11. After 15 seconds, push knob on the instrument panel
in to disengage cutting units. Stop the engine.
12.Measure the amount of oil collected in the container.
Divide the number of ounces collected by 32 to get gal-

lons per minute. (divide the number of milliliters col-
lected by 250 to get liters per minute). See chart in

13.If flow was greater than 0.7 GPM (2.6 LPM), repair

or replace the reel motor as necessary.
14.Disconnect tester from motor and hose. Reconnect
hose to the motor.
15.Remove cap from manifold port. Reconnect case
drain hose to the manifold block.

CAUTION
Keep away from reels during test to prevent per-
sonal injury from the rotating reel blades.
