Safety Precautions
Safe Operation Practices For
Failure to observe the following safety instructions could result in serious injury or death. Your complete and unimpaired attention is required at all times. Purchaser must give these instructions to the people operating and maintaining this tractor.
General Operation
Read, understand, and follow all instructions in this owners manual, the engine manual, the attachment manual and on the machine before starting.
Only allow responsible adults, who are familiar with the instructions, to operate the machine.
Clear the area of objects such as rocks, toys, wire etc., which could be picked up and thrown by the mower or other attachment.
Be sure the area is clear of other people & pets before operating. Stop machine if anyone enters the area. The operator is responsible for the safety of bystanders.
Before starting place the PTO lever in “Off” position and the gear shift lever in the neutral “N” position.
Never carry passengers.
Operate only from operators position, on the seat.
Do not operate in reverse unless absolutely necessary. Always look down and behind before and while backing.
Be aware of the attachment discharge direction and do not point it at anyone. Do not operate without either the entire attachment or the guarding in place and functioning properly.
Slow down before turning to prevent tipping or loss of control.
Never leave a running machine unattended. Always turn off attachment, set parking brake, stop engine, move shift control to first gear position, and remove keys to prevent unauthorized use before dismounting.
Turn off power to attachment when not in use.
Disengage attachment clutch, stop engine, remove key and wait for moving parts to stop before leaving operators position for any reason such as removing, cleaning, servicing, or unclogging the attachment.
Operate only in daylight or good artificial light.
Do not operate the machine while under the influence of medication, alcohol or drugs. Safe operation of this equipment requires your complete and unimpaired attention at all times.
Watch for traffic when operating near or crossing
roadways or drives. Follow traffic laws when operating on or near a road.
Use extra care when loading or unloading the machine into a trailer or truck. When handling equipment connect the chassis to the transporting vehicle. Never connect from control levers, rods, or like items that could be damaged.
Use only attachments or accessories designed for your unit. See your Gravely Dealer.
Wear sturdy footwear. Do not operate tractor barefoot or when wearing open sandals or canvas shoes. Do not wear loose clothing that may get caught in rotating parts of unit. Wear hand, head, ear and eye protection.
Slope Operation
Slopes are a major factor related to
Operate up and down slopes, not across. Do not operate on steep slopes.
Remove obstacles such as rocks, tree limbs, etc. from the area of operation.
Watch for holes, ruts, or bumps. Uneven terrain could overturn the machine. Tall grass or deep snow can hide obstacles.
Use slow speed. Choose a low ground speed so that you will not have to stop or shift while on the slope. Engage the directional control pedal slowly.
Follow the manufacturer’s recommendations for wheel weights or counterweights to improve stability.
Use extra care with grass catchers or other attachments. These can change the stability of the machine. Use only approved hitch points.
Limit loads to those you can safely control.
Keep all movement on the slopes slow and gradual. Do not make sudden changes in speed or direction.
Avoid starting or stopping on a slope. If tires lose traction, disengage attachment power and proceed slowly straight down the slope. If you must stop when going up the slope and can not safely back down, disengage the PTO, release the direction control pedal, and depress the brake pedal. Then place the gear selector in low speed and slowly release the brake pedal, while slowly engaging the direction control pedal.

Operation
NOTE: The light is activated when there is a loss of oil pressure. If the light comes on while operating the tractor, stop the tractor and engine as quickly as possible and check the engine oil level.
To check to see if the light is operating correctly, turn the ignition switch to the “ON” position. The light should glow red.
NOTE: The engine must have been off for at least five minutes prior to performing this test.
Correct Operating Speeds
WARNING: On rough and sloping ground and when mowing and trimming near buildings, trees, and other obstructions, use a slow ground speed.
NOTE: Most attachments, especially rotary mowers and snowblowers, perform best when operated at full engine speed. Proper ground speed is determined by power limitations, the type of terrain, the quality requirements of the job being performed, obstructions, hazards, etc.
Using the Attachment Lift Systems
Manual or hydraulic lift systems are used to raise and lower attachments. Either can hold an attachment in position or let it follow the ground.
Using the Manual Lift System
To hold an attachment in position:
•Lift the attachment to the raise position.
•Lift the lift range control and slide it to the desired position.
•Lower the attachment. The lift lever will stop against the lift range control. If the attachment is not in the desired position, repeat the first two steps.
To let an attachment follow the ground:
•Move the lift range control to the lowest position.
•Lower the attachment to the ground.
Using the Hydraulic Lift System
To hold an attachment in position:
•Lift the attachment by moving switch to the “up” position until the attachment is fully raised.
•Lower the attachment to the desired position by moving switch to the “down” position.
•When the attachment reaches the desired position, release the switch. The attachment will be held in that position.
To let an attachment follow the ground:
•Move the switch to the “down” position. When the attachment reaches the ground, hold the switch in the “down” position for approximately 1/2 second before releasing the switch.
Before Starting the Engine
Be sure that the tractor and engine have been properly serviced and maintained.
Operator Presence Control
The operator must be sitting in the seat to allow operation of the power take off (PTO) or traction drive.
CAUTION: The operator presence control is intended to stop the engine whenever the operator is not seated and the PTO and direction control pedal are not in the disengaged (PTO - Off, direction control pedal - Neutral) positions. Test this system each time the tractor is operated. If this system does not function as described do not operate until repairs are made. NOTE: Engine must not start unless PTO is disengaged and direction control pedal is in neutral.
Starting and Stopping the Engine
To start the engine:
•The direction control pedal must be in “NEUTRAL” position and the PTO control must be at “OFF”
position.
•Put the key in the ignition switch.
•Move the throttle lever to a middle position.
•If the engine is cold, move the choke lever to “ON”. If the engine is warm, the choke lever should be at
“OFF”.
•Turn the ignition key to “START”. When the engine starts, move the choke lever slowly to “OFF”. If the engine does not start in five seconds, release the
key for a few seconds and then repeat. If the engine does not start within five tries see section 6 for instructions.
CAUTION: Do not keep starter running for over 15 seconds. Do not run the starter for more than 15 seconds in any one minute.
7

Operation (Continued)
To stop the engine:
•Move the throttle lever to “SLOW” and idle with the PTO control disengaged for approximately 15 seconds.
•Turn the ignition switch of “OFF”.
•Remove the key before leaving the tractor.
Operating the Transmission
Use slow engine and transmission speeds until you know how to operate the tractor safely.
DO NOT SHIFT TRANSMISSION GEARS WHILE THE FORWARD OR REVERSE CLUTCHES ARE ENGAGED OR THE TRACTOR IS MOVING. This will damage the gears. Always place the direction control pedal in “NEUTRAL” and bring the tractor to a complete stop before moving the gear or range selectors.
To move in a forward direction:
•Start the engine and move the throttle to give the desired engine speed.
•Put the range and gear selectors in the positions that will produce the desired speeds. See section 7 for ground speeds produced.
•Move the direction control pedal forward. As the tractor increases speed, push the pedal until it locks into position. If the pedal is not pushed all the way forward, slippage can damage the forward clutch. USE CAUTION WHILE LEARNING TO
OPERATE THE DIRECTION CONTROL PEDAL.
NOTE: The operator must be in the seat to operate
the direction control pedal. If the operator leaves the seat with the direction control pedal in the “Forward” position, the engine will stop.
To move in a reverse direction:
•Follow the first two steps above.
•Push down firmly on the bottom of the direction control pedal. The control pedal does not lock into a reverse position. You must continue to push down
firmly to continue reverse travel. The pedal will return to “Neutral” upon release.
