MANIFOLD
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 faulty reel motor is to have
another person observe the machine while mowing in
dense turf. A faulty motor will run slower than other mo-
tors, produce fewer clippings and may cause clip marks
(a choppy appearance) on the turf.

Procedure for Reel Drive Motor Efficiency Test
1. Make sure hydraulic oil is at normal operating tem-
perature by operating the machine under load for
approximately ten (10) minutes.
2. Determine which reel motor is malfunctioning.
3. Park machine on a level surface with the cutting units
lowered and PTO switch off. Make sure engine is off and
mow/transport lever is in mow. Apply the parking brake.
4. Read Precautions For Hydraulic Testing in this sec-
tion.
