Brass tag

The 101 Junior and 101 Super were introduced in 1939. The 101 Junior had a 124 cu. in. continental motor for gas. I believe that for about $75 more a bigger continental motor (140 cu. in.) was available. The 101 Super had a 201.3 cu. in. Chrysler motor Both were available with standard front axle or row crop tricycle; front P.T.O. and power lift on R.C. models were optional as were rubber or steel wheels. The Junior was listed with individual brakes; the Senior had 1 pedal only; air cleaners were behind the grill. The Junior had a wire mesh grill with a removable door in the centre. The Senior had one side of the grill removable (wire mesh behind and chrome strips). The 101 was also listed with a kerosene motor (lower compression, hot manifold 140 cu. in.) The 101 Senior tested in Nebraska 1938. Both had 4 speeds forward, 1 reverse.

In 1939 and 40 the company used 31/8 bore motors in 101 Senior models. 1941 and 42 were very similar but 6 cyl. 101 models used 3 bore motors. 1940 saw models 81 and 82 appear. They had 124 and 140 motors respectively, different transmissions (4 forward speeds, 1 reverse); the differential was on the rear axle (101 were ahead of rear axle); the 82 was a kerosene model of 81 and had hot manifold lower compression, rad-shutters, pressed sheet metal corss-wise grill-louvres. 1940 also saw the 201, 202, 203 models, all large 6 cylinder tractors with very similar transmissions and final drive to the M-H 55. The 201 had a Chrysler 241.6 cu. in. engine. The 202 had a continental M 292 engine. The 203 had a continental M 330 engine, the latter two with 7 main bearings in the engine. They also had 4 forward speeds. A 1942 catalogue shows 9 models: 203,102 Junior, 82, 102 Seniorall kerosene or gas models; 81, 101 Junior, 202, 101 Super, 201gasoline models-called high compression; the others had 'regular' compression, would  burn gas or kerosene (distillate). The 102 Senior gas had a continental F226 motor; kerosene 102 Senior had a continental A244 motor. All 101s and 102s used very similar (if not identical) transmissions

1942 saw M-H also offering the General tractor, a small 2-plow tractor built by Cleveland Tractor Co. It had a Hercules engine. The 1943 catalogue shows 203G, 102G Senior, 102G Junior all on steel wheels, pressed steel grills with horizontal louvres (except the 201 which had heavy cast iron grill with horizontal louvres); also the 102 Sr. later had individual brakes. Since 1943 was war time with various shortages, the tractors came on steel and with no starters. They had Wico or F.M. magnetoes. Rubber tires were not listed as available in 1943.

A 1944 catalogue shows rubber and steel both listed. However, a catalogue listing didn't mean availability without waiting. Also a government-issued permit was needed when buying a tractor. These tractors were sold till about 1947 when the 20, 30, 44, 55 series were introduced. The 1943 catalogue does not show 81 in the line up. However, 81s were used by the RCAF for towing planes around the airport. They are pictured on front of the 1943 catalogue with bumper, pintle hitch, and heavy cast front wheels towing an airplane.

Quite a few replacement motors were sold as time went on, usually a high compression engine replaced a regular compression motor; an F 162 motor usually replaced an F140. (the 102G Junior used an F 162 high compression motor). This F 162 motor was also used in pumps, forklifts, air compressors etc. In my opinion they did and still are doing a pretty good job. The Chrysler engines were not as good in my opinion. They would not stand lugging so well if run at throttle. They did much better when run with the throttle wide open.

Twin power was a M-H feature. The normal motor speed was 1500 RPM. Twin power was when the speed was increased to 1800 RPM hence more power was used for belt work. Raised notches on the throttle quadrant are twin power notches.
