Dixon ZTR 4000 Series Operator's Manual page 13

The Dixon ZTR has a unique transaxle that requires only two drive levers to control braking, turning,
speed, and direction.
On initial operation, set throttle speed on slow and operate with mower blade "OFF". -To
avoid "over-controlling" the mower, use a light touch on the drive levers. Slight movements
using fingertip control is all that is necessary.
All controls are described from operators position:
PARKING BRAKE:
The parking brake used on the 4000 Series Models is des igned to hold the
mower from moving and is not intended for use in stopping the mower while it is
in motion.
Do not leave engine running for extended periods of time without the parking
brake engaged. Damage to the drive system could result.
TO SET PARKING BRAKE:
The hand operated parking brake is located at left hand side of mower. To
engage brake, pull lever up and to the rear. To release brake, move lever
forward and down.
NOTE:
TRANSMISSION DRIVE SYSTEM:
Allows the mower to turn on its own axis (zero turning radius).
Each lever controls one side of the mower.
