What’s a row crop tractor? Mainly, it means a tractor with an adjustable tread that can be set to match the spacing of the crops. The tractor also usually has a three-point hitch for mounting the implements used in row crop farming. Many row crop farmers need a PTO as well. In 1965, Minneapolis-Moline built a short pilot run called the G1000 Row Crop in versions fueled by diesel, LPG, and even a few by gasoline. These tractors were tested on farms, and a few changes were made before regular production started in November of 1965. M-M was slow to climb aboard the diesel bandwagon, but that changed once White bought them in 1963. Though their long-running 425ci six had started life in the late 1930s as a gasser, it had adapted well to diesel using the Lanova Power Cell combustion chamber. Updated in 1962 to 504ci with a 3/8-inch bore increase, the D504A-6 gave the new G1000 110 PTO horsepower in a Nebraska test done in November 1966. Bergman Farms owns this sweet 1967 G1000 Row Crop. The Bergman family has a long history with M-M tractors. Their collection is notable, and you are likely to see more of it in Tractor Talk. This is a big tractor, weighing almost 11,000 pounds without ballast. It’s an early-build 1967 (January 23, 1967, to be exact). Later in 1967, M-M changed the color scheme, eliminating the brown chassis paint and making the tractor all yellow. The white and black bands remained the same. These style of tractors are often called “Brown Bellies” by the M-M collecting communities. With a full load of weights, this tractor tipped the scales at 18,000 pounds. The G1000 Row Crop came standard with the Ampli-Torc, which was M-M’s trade name for a torque amplifier to split the gears. It allowed the operator to split each of the main five gears. The G1000 also had standard power steering, a dual-speed PTO, three-point hitch, and good-sized 18.4-34 rear tires. About 1,185 diesel G1000 Row Crops were made between 1965 and 1968—not including the run of 100 pilot models.Subscribe Our Weekly Newsletter Besides the row crop version of the G1000, a Wheatland was available. It had a fixed tread, rounded fenders with full tire coverage, operator close-out guards, Ampli-Torc, and power steering standard. The Wheatland came fueled by LPG or diesel only. Four-wheel drive was available using a Clark front axle. The Wheatland remained in production through 1969, with 2,050 produced—the highest number produced of any G1000 variations. The D504A-6 was the evolution of a 425ci gas six that debuted in 1938. It was used in only a few tractors until 1953. At that time, M-M licensed the Lanova system and made their first diesels. It weighs 2,700 pounds but only has four main bearings. The cylinders are parent bore, cast in pairs, and bolted separately to the crankcase, with a separate head for each. M-M used a Lanova combustion chamber, which was a step many manufacturers took to ease their transition to diesel fuel systems because it allowed them to use gas engine architecture. Fuel was supplied by a Roosa-Master pump in two calibrations, one for sea level to 3,000 feet, the other for 3,000 feet and above, though a dealer installed “altitude compensator” kit could be installed as well. Starting in late in 1967, the improved G1000 Vista was introduced and soon replaced the G1000 Row Crop. It featured a much-improved operator station isolated with rubber mounts, a tilt/telescope steering column, and new control layouts. Power output was the same, but a three-speed Ampli-Torc was introduced to better utilize it. The brakes went to a hydraulic setup, and a hydraulic boost was added to the clutch. Late in Vista production, closed center hydraulics were introduced. A four-wheel drive was optional. Some 1,610 Vistas were produced. The G1000 lines were replaced by the G1050s in the latter part of 1969. Not much changed except cosmetics as the White organization gradually morphed the M-M and Oliver lines into a new White brand identity. A few G1050s were rebadged as Oliver 2255s. Production of the G1050 ended at the end of the 1971 model year, which marked the end of this tractor line. The DNA of these tractors went back a long way, but the M-M name was nearing retirement. Most of the old products went by the wayside in favor of all-new White models that consolidated the combined expertise from the M-M, Oliver, Allis-Chalmers, and Cockshutt stables into current farming trends and technology. The operator’s station was about average for the era, but not long after this tractor was built, the G1000 Vista appeared with some big improvements in driver comfort. With the row crop tractors, you mounted the tractor from the forward edge of the platform on either side. The Wheatland was mounted from the rear. Moline was fond of casting parent bore cylinders in pairs. That way the same cylinder block, pistons, rods, bearings, cylinder head—plus all the related hardware—could be shared among engine families. The 4.63-inch bore was shared with a 336ci four. This had been M-M practice since the 1930s, and it lasted until the last of this style engine was built in 1971. Note the screwed-in Lanova cell pre-chambers in the cylinder head. The business end of the G1000 Row Crop shows the burly swinging drawbar and three-point hitch that was standard. The two shafts of the dual speed PTO are visible—the lower spinning at 540 rpm and the upper at 1000 rpm (at the required engine speed).
