An electric jack load balancing method and device for reducing the difference in load carried by each jack of a pair of electric jacks while adjusting the attitude of a platform. The device includes a controller configured to reduce the difference in load carried by each jack of a pair of electric jacks. The method includes monitoring the power draws of the jack motors of the pair of electric jacks, comparing the ratio of the power draws of the jack motors to a predetermined desirable power draw ratio, and when the jack motor power draw ratio differs from the desirable power draw ratio, modifying the operation of the jacks in such a way as to decrease the difference between their actual power draw ratio and the predetermined desirable power draw ratio.
