Minneapolis - Moline developed the powerline series to replace the ageing R, Z and U models. The 335 filled the lower to mid power slot at 33.5 belt horsepower while the 445 provided a power boost to the 40’s range and the Five Star models occupied the top tier at 54 PTO horsepower. These models were in production from 1956 to 1961.
The 335 was built in three variants: Industrial from 1957 to 1960, Universal from 1957 to 1959 and Utility from 1956 to 1961. A total of 334 industrial, 750 universal and 2500 utility tractors were manufactured. Serial numbers were stamped on the right side frame. You can find a list of the begining serial numbers for each year of production in the Steiner Tractor Parts Catalogs.
The 335 was evaluated at the University of Nebraska in Test No. 624 from June 7 1957 to June 17 of that year where the following information was noted. Observed maximum horsepower on the drawbar 29.84, belt hp 33.5.
The four cylinder vertical I head gasoline engine was built in-house by Minneapolis-Moline. With a bore of 3 ⅝ “ X 4” it displaced 165 cubic inches turning at 1600 rpm.
Power was transmitted through a dry disc clutch to a five forward speed transmission. Advertised speeds were: 1st. 2.72 mph, 2nd 4.17 mph, 3rd 6.36 mph, 4th 7.94 mph, and 5th 9.85mph. Reverse claimed 2.19 mph.
The 335 in these photos was exhibited at the 2018 Power from the Past Show presented by the Foothills Antique Power Association near Greer, SC. For information about the 2019 show on May 18, visit www.fapasc.com
