Gravely 420RX Operator's Manual page 12

A manual choke control under the seat assists in quick cold
weather starting. The infinitely variable torque converter
drive system means there is no clutching. Shift into either
forward or reverse when the vehicle is stopped and step on
the throttle pedal to go at speeds up to 25 mph in forward.
Never shift while vehicle is moving.
Braking is accomplished by pressing the brake pedal located
on the floorboard. This activates the rear hydraulic drum
brakes and front hydraulic disc brakes.
The parking brake is located in the center of the panel below
the seat. Pull the lever up to engage the parking brake. A
dash-mounted indicator light will remain lit until parking
brake is disengaged.
Indicating Lights and Gauges
1. Parking Brake Indicator Light: illuminates when the
parking brake is engaged. The light shuts off when the
parking brake is released.
2. Reverse Indicator Light: Indicates that transmission
is in reverse. Unit will move in reverse when the
parking brake is disengaged and the throttle is
depressed.
3. Neutral Indicator Light: Indicates that transmission is
in neutral.
4. Drive Indicator Light: Indicates that transmission is in
forward (drive). Unit will move forward when the
parking brake is disengaged and the throttle is

headlights and taillights are on.
6. Service Engine Light: Indicates low oil pressure
(below 14 psi) or low voltage (below 11.7 volts) when

light stays on and engine is full of oil. It is normal for
the oil light to illuminate whenever the ignition switch is
turned on and will stay lit until engine is running.
7. Fuel Level Gauge: Displays the approximate amount
of fuel in the fuel tank from empty (0) to full (1). The
gauge provides the most accurate reading when the
vehicle is positioned on level surface.

1/10 of an hour, the vehicle has run.
IMPORTANT: Hour meter continues to run if ignition switch
is on position and engine not running. ALWAYS turn ignition
