CONTROLS
All controls are described from operators position:
PARKING BRAKE:
The parking brake used on the ZTR 4500 Series Models is
designed to hold the mower from moving and is not intended for
use in stopping the mower while it is in motion. The engine will stop
if the parking brake is engaged while the control levers are in the
drive position.
TO SET PARKING BRAKE:
The parking brake is located on the right fender of Models
ZTR 4515B and ZTR 4515K.
To engage brake, pull lever up and to the rear. To release
brake, move lever forward and down.
NOTE: Always set parking brake before dismounting.
Release parking brake before moving mower.
TRANSMISSION DRIVE SYSTEM:
Allows the mower to turn on its own axis
"Zero Turning Radius". Each lever
controls one side of the mower.
NOTE: The pressure required to operate the mower is very light.
A minimum of 1/2 hour should be spent simply driving the
mower without the blade drive engaged.
