The Dubuque/Mannheim 20 and 30 Series NG Tractors

When the Dubuque Tractor Works began building the JD350 and JD450 Crawlers in early 1965, a major change was made in the way that serial number records were kept. Instead of having each model such as the 1010 and 2010 each having their own “block” of serial numbers, a new serial number sequence was selected, beginning at 10000, that would be used for all subsequent models of industrial and agricultural tractors, regardless of type. The 1010 and 2010 Tractors would continue to use their existing serial number sequences until production was ended; but their successors would adopt the new serial numbering system when introduced. The John Deere Werke Mannheim in Germany also adopted a system similar to the new Dubuque system. Simply said, this decision is the reason that model counts for the New Generation 20 and 30 Series Tractors do not exist, because every Dubuque-built product with an engine was serial numbered in sequence, whether it be an ag tractor, industrial crawler, log skidder, or road grader. All of these different products had different alpha-numeric build codes which makes it improbable that a count will ever be made of Dubuque-built tractors built after September 1965.

Not that it really matters that much. Since we’ve covered Dubuque’s industrial tractors several times, for now we’ll stick to the ag tractors. For 1966, the 38 horsepower 1020 and 54 horsepower 2020 Tractors were introduced, each with gasoline or diesel engines, and LU, RU, and HU chasssis configurations. A special option package was available for the LU models to make them more suitable for orchard and grove operations. It’s not likely that very many of these tractors were built. Of the three chassis types, probably the RU would be the most common, as would gasoline engines, although the percentage of diesel engines would increase as time went on, finally becoming diesel-only beginning in 1974.

In 1967, the Hi-Lo and Reverser transmission options were added to the Dubuque line, which makes the choices a little broader. Both 1020 and 2020 Tractors were available as an Orchard model, with distinct features such as fenders, a special hood, and other front sheet metal parts, which were options on the basic LU chassis. Dubuque also introduced a unique 2020 Grove and Orchard Tractor, dedicated for heavy-duty work in groves and orchards. Although also based on the 2020 LU Tractor chassis, the 2020 Grove and Orchard was different in many ways, including having a hand clutch.

For 1968, the 1020 and 2020 were joined by two new models; the 1520 Tractor, which featured a more powerful three-cylinder gas or diesel engine developing 45 horsepower, and was also available in an orchard model.For the smaller producer, the 31 horsepower 820 was imported
from Deere’s Werke Mannheim in Germany, which built utility-type tractors for Europe and other markets, including Canada.

The 2020 was replaced for 1972 by the 2030. The 820 and 1020
were so close in horsepower that both models were replaced in 1974 by the 830. The 1520 was superceded by the 1530 for 1974, and a larger model, the 2630, was introduced for 1974.

The 830, 1530, 2030, and 2630 were the last models of New Generation Utility Tractors to be sold in the United States. The 2030 was the last to have had an optional gasoline engine, and the last to have had an orchard option, although the option was not nearly as extensive as earlier models had been.

As stated earlier, no production numbers on any of these tractors are known, and it’s unlikely that they ever will be. However, it’s a lead pipe cinch that there weren’t many of the orchard tractors built, regardless of the model. Other combinations, say, a 2630 HU with Power-Adjusted Rear Wheels, gasoline engine, and Hi-Low Transmission aren’t likely to be common, either. A perusal of a Parts Catalog for any of them will reveal a number of variations, many of them likely to be scarce if not downright rare.

It’s not always numbers; collecting and restoring is about what a person likes and enjoys, not just about scarce or rare tractors. From the 1020 to the last 2630, there isn’t one of these tractors that can’t bring a lot of enjoyment to its owner. They make a lot of sense for a lot of collectors, as they are easy to mount and dismount. In these days of high fuel prices, they’re certainly much cheaper to haul, and parts availability is excellent.
But most of all, they’re handsome, with that classic Dreyfuss New Generation styling that has held up so very well over the years. Not only are they pr`etty, but they can be the most useful investment that an antique tractor enthusiast can purchase, because they were indeed “utility” tractors.
