Cold Weather Starting, Stopping the Engine

COLD WEATHER STARTING

Be sure to use the proper oil for the expected temperatures (check the table in the engine manual). Follow the normal engine starting instructions above. However, allow the engine ample time to warm up before putting the tractor under load.

USING JUMPER CABLES TO START ENGINE

WARNING: Batteries contain sulfuric acid and produce explosive gasses. Make certain the area is well ventilated, wear gloves and eye protection, and avoid sparks or flames near the battery.

If the battery charge is not sufficient to crank the engine, recharge the battery. If a battery charger is unavailable and the tractor must be started, the aid of a booster battery will be necessary. Connect the booster battery as follows:

•Connect the end of one cable to the disabled tractor battery’s positive terminal; then connect the other end of that cable to the booster battery’s positive terminal.

•Connect one end of the other cable to the booster battery’s negative terminal; then connect the other end of that cable to the frame of the dis- abled tractor, as far from the battery as possible.

•Start the disabled tractor following the normal starting instructions previously provided; then disconnect the jumper cables in the exact reverse order of their connection.

•Have the tractor’s electrical system checked and repaired as soon as possible to eliminate the need for jump starting.

STOPPING THE ENGINE

•Place the PTO switch in the “OFF” position.

•Move the RH and LH drive control levers fully outward in the neutral position.

•Engage the parking brake.

•Place the throttle control lever in the slow (idle) position. Run the engine for a short time to let engine speed stabilize at the idle speed.

•Turn the ignition key to the “OFF” position and remove the key from the ignition switch.

NOTE: Always remove the key from the ignition switch to prevent accidental starting or battery discharge if the equipment is left unattended.

PRACTICE OPERATION (INITIAL USE)

Operating a zero-turn tractor is not like operating a conventional type riding tractor. Although and be- cause a zero-turn tractor is more maneuverable, get- ting used to operating the control levers takes some practice.

We strongly recommend that you locate a reason- ably large, level and open "practice area" where there are no obstructions, pedestrians, or animals. You should practice operating the tractor for a minimum of 30 minutes.

Carefully move (or have moved) the tractor to the practice area. When performing the practice session, the PTO should not be engaged. While practicing, operate the tractor at approximately 1/2-3/4 throttle and at less than full speed in both forward and reverse.

Carefully practice maneuvering the tractor using the instructions in the following section "Driving the Trac- tor." Practice until you are confident that you can safely operate the tractor.

DRIVING THE TRACTOR

WARNING: Avoid sudden starts, exces- sive speed and sudden stops.

WARNING: Do not leave the seat of the tractor without disengaging the PTO, moving drive control levers fully outward in the neutral position, and engaging the parking brake. If leaving the tractor unattended, turn the ignition key off and remove key.

•Adjust the operator’s seat to the most comfortable position that allows you to operate the controls. See seat adjustment in the ADJUSTMENTS section.

•Release the parking brake.
