Operating Tips - Toro 30344 Operator's Manual

Each row in the logic chart below identifies input and output requirements for each specific product function.
Product functions are listed in the left column. The symbols identify specific circuit conditions, including
energized to voltage, closed to ground, and open to ground.

(-) Indicates a circuit closed to ground. ( LED ON)
(⊗) Indicates a circuit open to ground or de-energized (LED OFF)

A Blank indicates a circuit that is not involved with the logic.
(A) PTO input must be re-initiated after engine cool down (cycle key on-off)

To troubleshoot, turn on the key without starting the engine.
Identify the specific function that does not work and work
across the logic chart. Inspect the condition of each input
LEDs to ensure that it matches the logic chart.
If the input LEDs are correct, check the output LED. If the
output LED is illuminated but the device is not energized,
measure the available voltage at the output device, the
continuity of the disconnected device, and the potential
voltage on the ground circuit (floating ground). Repairs will
vary depending on your findings.

Operating Tips

•
Practice driving before operating the machine, because
it has a hydrostatic transmission and its characteristics
are different than some turf-maintenance machines.
When operating the machine and the deck, consider the
transmission, engine speed, load on the cutting blades,
and the importance of the brakes.
•
To maintain enough power for the machine and deck
while mowing, regulate the traction pedal to keep the
engine speed (rpm) high and constant. A good rule to
follow is to decrease the ground speed as the load on
the cutting blades increases; and to increase ground
speed as the load on the blades decreases. This allows
the engine, working with the transmission, to sense the
proper ground speed while maintaining a high blade-tip
speed necessary for good quality-of-cut. Therefore, allow
the traction pedal to move upward as the engine speed
decreases, and press pedal slowly as the speed increases.
By comparison, when driving from a work area to another
(with no load and the deck raised) have throttle in the

Another characteristic to consider is the operation of the
brakes. You can use the brakes to assist in turning the
machine; however, use them carefully, especially on soft
or wet grass, because the turf may be torn accidentally.
You can also use the brakes to control the direction of the
deck when trimming along fences or similar objects. The
other benefit of using the brakes is to maintain traction.
For example; in some slope conditions, the uphill wheel
slips and loses traction. If this happens, press the uphill
brake pedal gradually and intermittently until the uphill
wheel stops slipping; thus, increasing traction on the
downhill wheel. If independent braking is not desired,
engage the lever on left-brake pedal with right pedal. This
provides simultaneous braking at both wheels.
