Efficiency and durability from dual transmissions with large, 2.5 cm (1 in.) diameter axles

Dual transmissions efficiently power the ZTrak™ mower forward and reverse and give steering capability:

• Transmissions are set low in the vehicle for excellent hillside stability.

• Maintenance-free unitized transmissions are sealed and have no hose connections to leak hydraulic fluid.

Easy refueling with a conveniently located fuel tank

The fuel tank holds 11 L (3 U.S. gal) of fuel. It is located low on the left side of the machine:

• Fuel-fill opening is located low and angled for easy refueling.
• Large, 5.1 cm (2 in.) fuel-fill opening reduces the chance of spilling when adding fuel.
• Cap is tethered to the fuel tank to prevent the fuel cap from getting misplaced.
