Technically total maximum
permissible mass
4500kg (9921 lb)
It may depend on the load
capacity of the tires.

Front axle (*) 2000kg (4409 lb)
Rear axle 3150kg (6945 lb)
(4) Technically maximum permissible mass
When working with front-end loader or rear heavy loaded attachment installed to the 3-point linkage,
install the ballast weights on the counter-part axle to maintain the front and rear weight balance of
the tractor. If not, the front or rear axle can be damaged by the overloaded weight.
When working with the front loader, place the attached rear weight to the highest position and turn
the down speed control knob to the “Lock” position.
DO NOT exceed the total maximum permissible mass and/or permissible maximum mass on
each axle declared by manufacturer as below, even if the load capacity of the tire is sufficient.
If the load capacity of the tires is lower than maximum permissible mass on each axle, the
maximum mass on each axle must be loaded under the load capacity of the tire.
Check the load capacity of the tires.
▶ Maximum permissible mass is measured with only the front or rear wheels on the
scales inclusive of ballasts and with mounted equipment in the raised position.
▶ Do not exceed the maximum permissible mass above and/or the load
capacity of the tires. Overloaded operation may invalidate the warranty.
▶ DO NOT change the setting pressure of the relief valve arbitrarily to increase the
lift capacity of the front loader or 3-point linkage. It can cause fatal damage to the
hydraulic system and front axle.
Caution
* includes front mounted equipment or loader in the raised position but without load in the bucket.
Restrict operation: In case that driving speed of the tractor does not exceed 8km/h (5 mph) and
standard front/rear wheel tracks (refer to the chapter 4-5-(6), “Adjusting wheel track and tire
replacement” in this manual) are applied, the intermittent maximum permissible load of the front axle
can be 3200kg (7055 lb). But, it is restricted by the tire load capacity. (See next page).
