Cutter Deck Belt Adjustments - Scag Power Equipment SWZ Serie Manual De Operador

* Cold starting. In the spring and fall when the
morning temperatures are cool it may be
difficult to start the machine due to the
parastatic load from the hydraulic drive. To
relieve this load, pull out and up on the de-
clutch chain located on the right side of the
machine behind the tire. This will allow you to
start the engine easilly. When the engine is
warmed up, slowly release the de-clutch chain
to engage the hydraulic system.
4. Engage the cutter blades by pulling the blade clutch
switch into the ON position. Push the switch to
the OFF position to disengage the cutter blades.
-NOTE-
When PTO is engaged or (possibly) disengaged,
a squealing sound from the underside of the
machine is normal. It is caused by the electric
clutch plates meshing as the mower comes up to
speed. For best equipment life, engage the
clutch with the engine at 3/4 throttle, not under
full load.
WARNING:
If you are not familiar with the operation of the
hydrostatic drive and zero turn feature, practice
turning and maneuvering with the hand controls
before engaging the blades.
5. Release the parking brake. Move the speed
adjustment lever to the desired mowing speed.
-NOTE-
Top speed is suggested only for transport!
6. While squeezing the steering brake levers with both
hands, release both neutral latches.

both steering control levers.
10. To "freewheel" or move the machine around
without the engine running, turn the dump valve
levers located at the back of the pumps to the
"freewheel" positions (see Figure 1). To operate
the machine, the dump valve levers must be
returned to the closed positions.
