During 1935, a single-front-wheel version of the Model A, the AN, was announced, followed shortly by the AW with a wide-adjustable front axle, both models available on either steel wheels or rubber tires.
In 1937, the Hi-Crop ANH and AWH were added to the line with rubber tires only, and all were built after the change from ten- to twelve-spline rear axles at number 460000. These tractors offered greater clearance for bedded and other special crops. Their rear wheels had 40-inch (100-cm) centers in place of the standard 36 inches (90 cm).
MODELS BN, BW, AND BW-40 SHORT FRAME, 1935–1937
Almost as soon as the production four-bolt B was marketed, a BN option was introduced and referred to in advertising literature as the B Garden Tractor. It was aimed at beet, lettuce, and vegetable growers, for crops grown in 28-inch (70-cm)-wide rows or less.
From February 1935, a third alternative to the basic B, the wide-front axle BW, was offered, by which time the eight-bolt pedestal fixing was in use.
In 1936, six special wide-front-axle models were built with narrower axles, and these are now called the BW-40.
MODELS B, BN, BW, BNH, BWH, AND BWH-40 FOUR- AND SIX-SPEED, 1938–1946
The B was the model used for styling experiments, but both the restyled A and B were announced to the public at the same time.
In the case of the B, the opportunity was taken to increase its power by adding an extra 0.25 inch (6.25 mm) to both bore and stroke. This increased power on steels from 11.84 to 14.03 drawbar hp and 16.01 to 18.53 belt hp or 16.44 drawbar hp on rubber tires.
Twelve-spline rear axles, as fitted to the unstyled BNH and BWH, replaced the ten-spline of the earlier models, and the whole back end was strengthened. As with its larger sibling, the B series was offered in 1940 with electric starting and lighting and the resulting long hood. It was also changed from 36- to 38-inch (90- to 95-cm) rear wheels.
The 1941 model had an extension to its muffler, and rubber-tired versions received a six-speed transmission like the A. Again, material shortages during the war made the fitting of pressure radiators necessary from numbers 148500 to 166999.
The PTO on the B was increased to 13/8 inches (84.375 mm) from number 149700 to remain in line with the competition, but war conditions precluded any further changes.
The styled B was available as a twin-front B, single-front BN, normal wide-axle BW, BNH and BWH Hi-Crops, and a special BWH-40 with 42-inch (105-cm) rear tread for 40-inch (100-cm) bed crops; only twelve BWH-40 tractors were built.
As on the unstyled models, the rear tires were officially 36 inches (90 cm) on standard models and 40 inches (100 cm) on the Hi-Crops, all of which were rubber tired. Powr-Trol was an option from October 1945.
