The values quoted here apply to forage harvesters equipped with four-wheel drive. Ballast on the rear axle must be increased by approx. 170 kg (375 lb.) on forage harvesters equipped with two-wheel drive.

IMPORTANT: On 73XX to 79XX (3-speed) forage harvesters, 540/65R28 tires on the rear axle are not approved for use with the support wheel.

IMPORTANT: Do not overload rear tires, especially when rotary harvesting unit is removed.

1 If more than 16 suitcase weights, each weighing 50 kg (110 lb.), are used, it is not permitted to install the trailer mounting.
