The 190 XT had a six cylinder engine and a 3.875x4.25 inch bore/stroke. Its displacement was 301 cubic inches and its rated RPMs was 2200. This engine was a new design and, for the time, offered excellent performance for its displacement. Its main transmission, basically a carryover from the D19, had 4 forward and 1 reverse gear and was not synchronized. The 190XT had a power director like the D Series, but it could not smoothly shift on the go (clutch engaged). The main transmission could not be shifted while the PTO was engaged and turning and as such the 190 did not offer true live PTO. You could start and stop the tractor using the power director but you could not, for example, shuttle from forward to reverse without first stopping the PTO. The power director did split each gear allowi

  • The 190 XT had a six cylinder engine and a 3.875x4.25 inch bore/stroke. Its displacement was 301 cubic inches and its rated RPMs was 2200. This engine was a new design and, for the time, offered excellent performance for its displacement. Its main transmission, basically a carryover from the D19, had 4 forward and 1 reverse gear and was not synchronized. The 190XT had a power director like the D Series, but it could not smoothly shift on the go (clutch engaged). The main transmission could not be shifted while the PTO was engaged and turning and as such the 190 did not offer true live PTO. You could start and stop the tractor using the power director but you could not, for example, shuttle from forward to reverse without first stopping the PTO. The power director did split each gear allowing for a total of 8 forward speeds and 2 reverse speeds. The 190XT, because it used many D19-size components in its powertrain, was intended to be at most a hp (kW) tractor. However, many of them had their injection pump turned up, pushing them to 120 horsepower or more. This led to various powertrain failures, especially in earlier models due to a light rear end design. An improved design was introduced and many tractors were updated with the heavier duty rear end. Also, the 190's transmission did not tolerate grinding during gear shifting well and this led to many tractors with transmissions that would not stay in certain gears. As such the tractor got somewhat of a bad reputation among those that weren't AC fans. The 190XT was gradually beefed up, becoming the 190XT Series III and eventually the Model 200. When operated as intended by the manufacturer, the 190 was a reliable tractor. However, this meant accepting its limitations and not, for instance, trying to shift it like a John Deere 4020 with its synchronized transmission or pulling implements designed for D21-size tractors. Despite stiff market competition from the John Deere 4020 and others, Allis did sell many 190XT tractors and there are many still working today. Allis became AGCO Corporation in 1985 after corporate restructuring and as such what parts are still available for these tractors are mostly available through AGCO.
