Operation Product Overview Operation Note: Determine the left and right sides of the machine from the normal operating position. Pre-Start Make sure you understand the controls, their locations, their functions, and their safety requirements. Ensure the blower, belt cover, bags, tube and hood are in good condition, properly attached, and latched. For units above Serial Nos. 600,000 with Triton decks: Make sure that the adjustable dog leg baffle is closed to match the intake into the Ultra Vac Blower.
Operation 3. To remove the bags, shut off deck drive, stop the engine and wait for all moving parts to stop. Open the hood and remove the bags by lifting up on the rear of the bag, then unhooking the front clip. Empty bags by inverting them. 4. Reinstall bags, close and latch the hood before continuing mowing. Tips for mowing conditions: • When mowing in areas with sandy soil, use low lift blades on the cutting deck and higher cutting heights to minimize wear on the blower components.
Operation 8. Remove the hair pins and clevis pins holding the hood assembly to the mount weldment. CAUTION The deck sheave will become very hot. Touching a hot deck sheave can cause severe burns. 9. Lift the bag and hood assembly off the mount. 10. For units with a 2 post ROPS installed: Remove the hairpins and lift the front weight off of the mount plates (see Figure 8). Allow the deck sheave to cool completely before removing the belt. 4.
Operation 7. Install the belt cover using the two knobs. Install the discharge tube assembly by slipping the upper end into the hood, then sliding the lower end over the blower discharge opening. Use the latches to retain the lower end to the blower. WARNING Loading a unit on a trailer or truck increases the possibility of backward tip-over. Backward tip-over could cause serious injury or death. 8.
Operation ramp angle. The trailer or truck should be as level as possible. Important: Do Not attempt to turn the unit while on the ramp, you may lose control and drive off the side. Avoid sudden acceleration when driving up a ramp and sudden deceleration when backing down a ramp. Both maneuvers can cause the unit to tip backward.
Maintenance Maintenance Note: Determine the left and right sides of the machine from the normal operating position. WARNING WARNING While maintenance or adjustments are being made, someone could start the engine. Accidental starting of the engine could seriously injure you or other bystanders.
