4.If the tractor is started where there is a height limitation, immediately return the Roll-Over Protective Structure (ROPS) to the unfolded "up" position and locked securely and fasten the retractable seatbelt.

5.Start the engine of the tractor only by using the starter key switch. Avoid starting the engine by short circuiting across the starter solenoid terminals with a jumper wire, or by bypassing the safety start switch. This defeats the safety

1. SAFETY PRECAUTIONS

interlock circuit and the tractor may begin to move and/or the Power Take Off (PTO) shafts may begin to rotate, possibly leading to personal injury or property damage.

6.Avoid running or idling the engine in a confined area that is poorly ventilated or not ventilated at all. The engine emits carbon monoxide gas that is colorless, odorless and can cause death.

7.Before operation, check that all the safety features are functioning correctly. Never tamper with safety devices. Check the proper operation regularly. Contact YOUR LOCAL YANMAR TRACTOR DEALER for safety devices malfunction.

8.Avoid accidental contact with control pedals while the engine is running, as this can cause unexpected movement of the tractor.

9.Always attend to the running tractor.

2. Work with the Tractor

1.Tow an implement only with the drawbar. Avoid hitching via the axle housing. The tractor can upset its balance, leading to serious injury or death. Make sure the drawbar pin is locked in place.

2.Any towed vehicle with the total weight exceeding that of the tractor should be equipped with its own braking system that is operational from the tractor operator seat.

3.Make sure that all the covers and guards are in position. Replace any missing or damaged covers immediately.

4.Before turning or during traveling on a rough terrain, or before stopping, decrease the tractor speed in order to prevent upsetting.

5.Use extra caution during operating over rough ground, when crossing ditches or operating on slopes and when turning corners.

6.Avoid turning with the differential lock engaged. Attempting to turn the tractor while the differential lock is engaged can lead to a roll over.

7.Stay clear of ditches, potholes, embankments or ponds. The incident of upsetting the tractor can

occur more on soft or wet ground. Before entering an area covered with tall grass, inspect the area to detect any obstacles.

8.The operator should always pay attention for blind corners, trees and other object that can obstruct the operator's vision. The operator should always remain alert when approaching the row of trees or any obstacle.

9.When two or more people are working in one area, always keep in good communication between each other.

10.Do not under any circumstances get on or off the moving tractor.

11.When driving at night, ensure that all necessary lights are illuminated.

12.When driving, do not shift the range gear. Always shift the range gear when the tractor is completely stopped.

3. Stop the Tractor

The procedures of stopping the tractor are as follows:

1.Make sure that the left side brake pedal and the right side brake pedal are connected with the brake pedal connector lock.

2.Reduce the engine speed.

3.Depress the clutch pedal completely to disengage the clutch.

4.Depress the brake pedals to stop the tractor.

5.Move the primary gear to the N (neutral) position.

4. Considerations for Safety of a Child

Tragic accidents can occur if the operator is not alert to the presence of a child. A child is often attracted to the tractor. A child does not understand the dangers. Never assume a child will remain where the operator last saw the child.

1.Keep a child out of the operating area and under the watchful care of an adult other than the operator.

1-5

Lx410/450/490 Operator's Manual

1. SAFETY PRECAUTIONS

2.Be alert if a child enters the work area, stop the tractor immediately.

3.Never allow a child to ride on the tractor. The child can fall off and be seriously injured or interfere with safe tractor operation.

4.Never allow a child under 16 years old to operate the tractor. A child, 16 years old and under should only operate the tractor under close parental supervision and proper instruction.

5.Be extremely careful when backing the tractor. Before and during backing, look back and downward. A child may be in the path.

6.Use extra care when approaching blind corners, shrubs, trees or other objects that may obscure the operator’s vision of a child or other hazard.

7.Never allow a child to play on the tractor or implement.

8.Keep a child away from hot or running engine. The child may suffer burns.

5. Operate the Tractor on Slopes

On a slope, the tractor is less stable and more prone to tip over, possibly leading to serious injury or death. Remain very cautious while the tractor is on any slope.

to avoid false confidence in the tractor’s ability to climb slopes.

To improve stability on a slope, select the widest possible tire tread width. Observe the instructions for appropriate weighting.

A2019005

DO:

Operate up and down slopes, not across.

Remove obstacles such as rocks, limbs, etc.

Watch for potholes, ruts or bumps. Uneven terrain can overturn the tractor. Tall grass can hide such obstacles.

Place the transmission in the low range when climbing or descending slopes. Always keep the tractor in gear when going down slopes to take advantage of engine braking action.

Keep all movement on the slopes slow and gradual. Do not make sudden changes in speed or direction. Rapid engagement or braking can cause the front of the tractor to lift and rapidly tip over backwards which can cause serious injury.

Avoid starting or stopping on a slope. If tires lose traction, push down Power Take Off (PTO) switch to OFF position and proceed slowly straight down the slope.

To avoid upset, move backward up a steep slope. If backing on the slope is difficult, do not attempt to continue. Avoid an extremely steep slope.

When moving forward to get out from a ditch, deep mud or when traveling on a steep slope, the risk of the tractor upsetting backward is high. Always move backward to get out from these situations. In the 4-wheel drive mode, special caution is needed

Lx410/450/490 Operator's Manual

1-6

DO NOT:

Keep away from drop-offs, ditches or embankments during mowing. The mower could suddenly turn over if a wheel goes over the edge of a cliff, ditch or if an edge caves in.

!WARNING

Before approaching a slope, select an appropriate speed setting. Make sure to run the tractor at a lower speed on slopes. Never attempt to shift gears on a slope. The tractor can suddenly go downhill out of control. Avoid increasing and decreasing the tractor speed rapidly.

Do not move the range gear lever in the N (neutral) position when on a slope.

When climbing or descending a slope, do not shift the range gear lever. Shifting the range gear lever into the N (neutral) position can result in loss of control of the tractor.

Starting the tractor with the front end uphill can cause the front wheels to jump off the ground and this situation poses an extreme danger. To avoid this problem, run the engine at a lower speed, and gently start the tractor.

Avoid parking the tractor on a slope. If parking on a slope is unavoidable, chock all the tires safely and securely and engage the parking brake securely, for details, see "6. Lock and Set the Parking Brake" on page 7-4.

Avoid depressing the clutch pedal when operating on a slope.
