Tractors of the lowest performance class were also produced and sold in North America. Massey-Harris also wanted to get involved in this performance class and developed the pony 11. The competition in this class consisted, for example, the John Deere L, the Allis-Chalmers G or the IHC Farmall Cub. These tractors found their customers from small sideline companies, in nurseries or as a court tractor in large companies.

Series production began in 1947 with the Motor N62 from the supplier Continental. He was operated with petrol and had a displacement of one liter. The performance of 11 HP was brought to the rear wheels via a gear with three forwards and a reverse gear.

Despite small wheels, a high ground clearance was reached with portal axes at the front and back. The engine rested in a cast frame, a support tube went backwards as with support tractors with an intermediate axle operation of attachments.

The tractor sold quite satisfactorily at first, but in the 1950s the quantities decreased more and more. In 1954, production was discontinued according to over 28,000 copies sold.

A real rarity with only 74 copies remained the industrial variant Pony 14, built from 1951 to 1954. In addition to the normal coupling, he received a fluid coupling in addition to the normal coupling in order to enable him to carry heavy loads such as freight cars, load barges or even aircraft Cars were used as "Fluid Drive". As a result, a jerk -free start was also possible with a high load without overloading the normal clutch. The front axle was generally sprung.

At Massey-Harris, it was recognized in the early 1950s that Europe with its many small businesses was an ideal market for small tractors. So in France in 1952 production was started with the Continental engine, the name was changed to distinguish from the Canadian model to Pony 811.

However, there was soon a suitable engine at Simca in Europe. The petrol engine, which was also built into the Simca Aronde and some other cars, originally had 40 hp, but was throttled for the tractor on an indexable 15 hp. For this, the cast frame that carries the engine also had to be adjusted.

In this new construction, the name was changed to pony 812, in some sales areas also on pony 840. The tugs became a glossy success, a total of over 50,000 copies were sold.

In the 1950s, petrol -powered tractors were increasingly sold in Europe. This was also recognized by Massey-Harris and searched for an alternative for diesel operation. The D621 engine was found at Hanomag in Hanover. The two -stroke two -cylinder were stinking rating books, but was well suited for the drive of the small tractor.

The Hanomag engine with one liter of displacement was set to 18 hp performance according to the literature. However, the models I photographed had all 20 hp, there were apparently differences here. The gearbox had five forward gears and a reverse gear.

The tractor was now called Massey-Harris Pony 820, also MF21 in some areas. In 1959, after a low revision, a renaming to Pony 821 was renamed. In the construction period from 1957 to 1961, sales success were achieved again, over 40,000 copies came to the customers.
