The History of Allis Chalmers D17

how much does a allis chalmers d17 weight

Allis Chalmers D17 tractor is a part of the Allis Chalmers D series, manufactured from 1957 to 1969. The D-series tractors were initially produced to replace the previous line of tractors. The new series focused on delivering higher horsepower and better reliability.

The tractors from the D-series were equipped with a three-point hitch, diesel engine options, power steering, and low-compression fuel options.

The majority of the D-series tractors offered a hand-operated shift on-the-go clutches. The hand clutch was available in all models except for the D21.

One of the unique features of the D-series was the previously mentioned hand-clutch, popularly known as Power-Director. This system made every tractor worth the price. The power director indicated that the clutch was in a low position when it was pulled back, while it stayed neutral in the middle and high in the forward range.

The Allis Chalmers D17 tractor was produced in 1957 as a replacement for the popular WD45 tractor. Style-wise, the D17 tractor resembled the D14 model. The tractor was sold in diesel, gas, and LPG engine versions.

The tractor offers a wide clearance, wide front, and narrow dual and single front wheels. The D17 tractor was also built as an orchard model, a wheatland model, while the taller version was excellent for sugar cane agricultural work.

It’s interesting to note that this great tractor underwent several changes throughout production. The most notable D17 tractor is the series IV, also known as the last series.

In 1968, the Allis Chalmers D17 tractor was replaced by the 170 models.

Allis Chalmers D17: Transmission

The Allis Chalmers D17 tractor features a partial power shift transmission with eight forward and two reverse gear options.

One of the most notable features in this review is the Power Director. The power director is a transmission model commonly used with Alli Chalmers D-series.

Other tractors may not deliver smooth transmission, but the D17 is an exception. Instead of using a foot clutch, you can put the Power Director in a neutral position. This is an excellent feature that lets you operate different equipment and tasks. For example, most people found this system beneficial for snow hauling or hay baling.

In addition, the partial power shift transmission allows this great tractor to shift more than two speeds without clutching.

Allis Chalmers D17: Hydraulic & PTO

does allis chalmers d17 have live pto

The Allis Chalmers D17 hydraulics is an open-center type. As you may be familiar, the open center hydraulics offer the advantage of using a single central pump. In addition, the open-center hydraulic system allows you to use more than one pump in different stages for different farm applications.

The live PTO and live hydraulics are only available with the Series IV. However, they only apply with a power director that stops the tractor’s ground. When the live hydraulics and the three-point hitch are combined, this tractor can utilize and load heavy-duty tasks with little work.

On the D17 tractor, the PTO power is supplied from the PTO shaft, located behind the flywheel foot clutch and ahead of the power director transmission.

One of the best things about the Allis Chalmers D17 tractor is that it uses an oil bath. So if you are ever stuck in a heavy baling, brush hogging, or similar operations, you can put the PD in a neutral position.

For instance, the D17 Series I, series II and series III are equipped with a snap coupler and have the piston type high pressure pump in the torque tube. The hydraulics stop as soon as the foot clutch is activated. However, it continues to work when the power director is neutral.

The Allis Chalmers D17 is a bit tricky for loader work, but nothing an experienced operator cannot manage. Before you purchase the aftermarket tractor, make sure to test drive it and check the hand clutch.

The Series IV is available with a snap coupler or a Category II three-point hitch.
