4. OPERATION INSTRUCTIONS
4.1 Controls
4.1.1 Operator Presence Control (OPC) Levers: Located on the upper handle
assembly directly above the handle grips.
When these levers are depressed,
the OPC system senses that the operator is in the normal operator's
position.
When the levers are released, the OPC system senses that the
operator has moved from the normal operating position
and will kill the
engine if either the speed control lever is
not in the neutral
position or the
blade clutch is engaged
.
4.1.2 Speed Control Lever: Located in middle of control console, it controls the
maximum forward speed and is infinitely variable from neutral (0 mph) to 6.2
mph.
4.1.3 Drive Levers: Located on each side of the upper handle assembly directly
below the handle grips (See Figure 5). These levers individually control the
speed and direction of each drive wheel. When the speed control lever is
moved out of the neutral position and the neutral lock latches are moved
into the drive position, as shown in Figure 5, and the drive levers are released,
the drive wheels are engaged in the forward direction.
Squeezing the left hand and/or right hand lever causes the left hand and/or right
hand drive wheel respectively to slow down, stop, or reverse, depending on how
far each drive lever is "squeezed". Squeezing the drive levers beyond the
neutral position causes the drive wheels to engage in the reverse direction
regardless of the position of the neutral lock latches and the speed control lever.
4.1.4 Neutral Lock Latch: Located directly above the drive levers. These latches allow
the operator to lock the drive levers in a "neutral" position where neither of the
drive wheels are engaged in either a forward or reverse direction (See Figure 5).

4.1.5 Blade Engagement: The “push/pull” blade engagement knob is located on the
left side of the control console. To engage the blades, the knob must be pulled
toward the operator until the turnbuckle (attached to the blade engagement
idler) locks over-center. To disengage the blades, push the knob down until the
assist arm contacts the pin on the deck.
4.1.6 Throttle-Choke Control: The throttle-choke control lever is located on the
control console right side. Choke aids in starting a cold engine. The choke
control is a part of the throttle control and activates by moving the throttle
control lever to the full forward position. You will notice a detent at the “full
throttle” position (approximately 3/4” from top of slot) continue pushing forward
into the “choke” position.
