    In the late ’40s and early ’50s, diesel powered tractors were just starting to increase their market share against gasoline and distillate (kerosene) power tractors. It was a good time to jump in and gain a foothold in that market and Richard Sheppard did just that by incorporating his own Sheppard diesel engine into a tractor designed at the Sheppard engine factory in Hanover, Pennsylvania.

    The story begins in 1933, when Sheppard opened a small engineering and manufacturing company in his home town of Hanover shortly after graduating from Dickinson College. Robert was one of “The” Sheppards, a family well known in the area for owning and operating the gigantic Hanover Shoe Factory. Among other things, Robert’s company manufactured wire screen for sieves used in flower sifting as well as manufacturing small gasoline generators for use on farms. Sheppard had a particular fascination with the diesel engine and strove to design and build a low cost diesel. By 1937, he had succeeded well enough to reform his company into the R.H. Sheppard Company for the manufacture of diesel engines. These were mainly for use as generators and to power refrigeration units, but also for marine use and as stationary power. Eventually, 20 different models were produced, from 5 to 100 hp and with one to six cylinders.


    ike other manufacturers, World War II would send Sheppard into a frenzy of building for the war effort. This would mainly be lightweight one-cylinder diesel marine power units for lifeboats, and Sheppard built thousands of them, along with generator sets. After the war, the engine business continued as usual but Sheppard became more and more interested in furthering the cause of diesel power in tractors. To that end, he began developing a tractor line but also a repower kit for existing tractors, both debuting in 1949.

    The repower kit was developed for the International Harvester Model M, which had started production in 1939 and was the larger rowcrop tractor in the IH lineup. It had a 247 ci I4 fueled by either gas, distillate or diesel, making 36 PTO hp in gas form and 35 hp in diesel. The 3-cylinder, 188 ci diesel for the conversion was rated at 32 belt hp. It was claimed the conversion could be installed in less than a day but most experts think that could happen only with an experienced person doing it. Sheppard advertised a 75 percent fuel savings but the power drop was significant. It isn’t clear if other kits were planned but, at $1,200 a pop, they didn’t sell many of the Model M repower kits and the idea was quietly dropped

    At nearly the same time, Sheppard introduced his own line of tractors in one, two and three cylinder varieties making 5.4, 24 and 32 flywheel hp. The one-lung SD-1 came only in ’49 to the tune of 10-14 tractors only. In ’53, the four-cylinder, 51 hp SD-4 was introduced. In between were the two-cylinder, 24 hp SD-2 and three cylinder, 32 hp SD-3.

    The tractors were only moderately successful, due mostly to financial elements. To start, Sheppard did not offer a financing deal to its small network of dealers around the country. It was cash and carry and not one tractor rolled off the line unless it was paid for in full. Secondly, the retail prices of the tractors were above the market in their classes. At $1,095, the SD-1 was very much priced out of the market. The SD-2 cost $2,695 and faced the same obstacle. The SD-3 was $2,995 and was priced just about right for its segment. The later SD-4 was around $4,200 and, again, was priced above the market in its class. In terms of features, the Sheppards compared well to similar tractors on the market, though they were a little light on power in their class. One feature that appeared on the SD-4, and made it standout, was power steering. Sheppard wanted to offer that feature in tractors from day one but couldn’t find anything applicable… so he built his own system. This would signal a new direction for the R.H. Sheppard Company later in the ’50s.
    The SD-2 and SD-3 shared most features, including a final drive from Timken-Detroit Axle and are reputedly the same as used in Cockshutt tractors. They came standard with a 4-speed transmission but a two-speed range box was optional. Live hydraulics and two PTOs were also optional. They were offered with a narrow front or an adjustable-track wide front, in a wheatland-style fixed tread, an orchard model or an industrial configuration. The SD-1 and SD-4 used a powertrain designed by Sheppard.

    The Sheppard tractors were unveiled at the Pennsylvania Farm Fair in January of 1949 and discontinued at the end of 1956. Engine production continued into the ’60s but eventually R.H. Sheppard transformed from an engine and tractor manufacturer to a power steering gear manufacturer and has enjoyed great success in that field to this day. Their primary product lines are for big truck and tractor applications. They also manufacture specialty products to order.

    In seven years, Sheppard made only a few over 1,600 tractors. With 1,209 built, the SD-3 was the most numerous and also has the most survivors

    Shepard is still around primarily focusing on producing power steering and diesel pumps. A three cylinder diesel was an odd duck in the late 1940s but is quite common in compact and mid size utility tractors today. This is a 1/16 scale model produced by Nolt. Nolt was a custom toy company founded by David Nolt in Pennsylvania for the purpose of producing under represented models in 1/16 scale. My Shepard model was likely produced in 1993 and is marked serial number #061. Thus this means it's likely 1 of perhaps less than 200 ever produced. Scale Models in the mid 1990s also produced a 1/16 scale model.

    The model has a warm charm with diecast rims, metal exhaust stack and fairly decent paint for the age. With this being a limited run model there is no working steering and is thus intended as an adult collectible rather than a child's toy. This was purchased at the Tri-County annual winter auction at the Best Western Hotel in Arcola, Illinois in early February of 2020.

    From articles in Toy Farmer Magazine I am familiar with the custom work of David Nolt - incredible models from him! The Shepard brand o tractor is a new one to me - thank you for sharing this model with us and the wonderful background information you provided about the Shepard company.

      Very neat story on the tractor and the diecast. Thanks for sharing.

      I hope someone will bring out more of these uncommon tractors in 1/64 one day.
