Brakes and Drive System

Brake system description
The RZT-S uses twin EZT Hydro-Gear transmissions to drive the rear wheels. The hydraulic action of the trans-
missions will provide the braking for the mower while it is in motion. There is a friction brake on the transmission that
is used as a parking brake.
• There is a brake for each transmission.
• They are activated by depressing the brake pedal.
• Depressing the brake pedal will cause the control
pedal shaft to rotate. When the shaft rotates, a bell
crank attached to it will pull on the main brake con-
trol rod. See Figure 4.1.
• The main brake rod will pull on a bell crank
attached to the brake shaft. This will cause the
brake shaft to rotate.
NOTE: The brake shaft is held captive on the deck lift
shaft. It is serviced with the deck lift shaft. Refer to
the deck lift shaft section of Chapter 7: Decks and
Lift Shaft for removal/replacement procedures.
• As the brake shaft rotates, the two bell cranks will
pull the secondary brake rods. The secondary
brake rods will pull on the brake caliper arm, push-
ing the brake pins into the caliper, applying the
brakes. See Figure 4.2.
• A brake link rod connects the right brake shaft bell
crank to the drive belt idler pulley bracket. When
the brakes are applied, this link rod pulls on the
idler pulley bracket, de-clutching the drive belt.
