Toro Groundsmaster 4000-D Service Manual page 143

NOTE: The front wheel motors on your Groundsmaster
are identical (Fig. 68). The rear axle motor includes a
flushing valve for cooling of the closed loop traction cir-
cuit and therefore has some differences from the front
motors (Fig. 69). Service of the wheel and axle motors
uses the same procedure.
NOTE: For service of the front wheel and rear axle mo-
tors, see the Sauer--Danfoss K and L Frame Variable
Motors Service Manual at the end of this chapter.
