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 typically run slower, pro-
duce fewer clippings and may cause clip marks (a
choppy appearance) on the turf.
IMPORTANT: DO NOT perform the Cutting Reel Mo-
tor Cross−Over Relief Pressure Test on Reelmaster
3550−D OR 3555−D machines. The reel motors on
these machines do not have cross−over relief
valves.
NOTE: Before testing the cutting reel motor cross−over
relief pressure, make sure that reel motor is in good con-
dition by performing the Cutting Reel Motor Efficiency
Test (see Reel Motor Efficiency/Case Drain Test in this
section).
