Continuing the expansion policy, the La Crosse Plow Company was added October 1, 1929.  Founded in 1865 to manufacture a full line of horse-drawn implements, to which was added a line of heavy tractor plows, listers, disc harrows, etc., (when the tractor line first came into use) it eventually grew to be one of the larger independent manufacturers of its kind in the country. This factory made and marketed the first balance-frame horse-lift cultivator; the first power-lift grain drill with a fluted feed (still popular today) ; the first power-lift tractor plow ; and the first three-row wheatland listing plow, which was later copied by other plow makers. In keeping with this advanced engineering, the La Crosse Works, after becoming a part of the Allis-Chalmers organization, developed the first drive-in cultivator and has been first in many new and original developments. This plant now builds a full and complete line of power tillage implements, planters, listers, harrows and mowers.

In 1931, the Advance-Rumely Co. of La Porte, Indiana, became a part of the Allis-Chalmers organization. This large manufacturer of tractors and threshing machinery, with a record of continuous operation dating back to the 1836, represented a series of consolidations which included the Advance Thresher Co. of Battle Creek, Mich., the M. Rumely Co. of La Porte, Ind., Gaar Scott & Co. of Richmond, Ind., and several others.
