Brake system description
The Z-Force-S uses twin HydroGear transmissions to drive the rear wheels. The hydraulic action of the transmis-
sions will provide the braking for the mower while it is in motion. There is a friction brake on the transmission, but it is
used as a parking brake.
NOTE: Mowers equipped with a 48” deck have HydroGear EZT transmissions with the brakes on the inboard
side of the transmissions (shown below). Mowers with the 60” deck are equipped with HydroGear
ZT2800 transmissions. The brakes for the ZT2800 transmissions are mounted to the frame of the
mower on the outboard side of the transmissions. The brakes for both the EZT and the ZT2800 trans-
missions function and are serviced the same way.
• There is a brake for each transmission.
• They are activated by moving the parking brake
lever to the “ON” position.
• The parking brake lever operates the brake shaft.
• The brake shaft has three bell cranks. The two
outer bell cranks are for applying the brakes. They
are connected to the brake caliper cam arms by
extension springs.
• When the cam arms are pulled forward, they push
on the brake pins with a cam action applying pres-
sure to the brake pads. See Figure 3.1.
• The center bell crank on the brake cross shaft
assembly has a link that is connected to the drive
belt idler pulley bracket. When the parking brakes
are applied, the idler pulleys are pulled away from
the drive belt. This de-tensions the belt, disengag-
ing drive to the transmissions. See Figure 3.2. The
adjustment procedure for the brake link is covered
in the drive belt adjustment section of Chapter 5:
Drive.
