WD45 Snap Coupler

Al Negstad · Nov 3, 2014

I'm considering purchasing a WD45 with a Snap
Coupler. Which level controls it? What do I need
to know to use it? Does it have a separate oil
reservoir? What do I need to know about the
hydraulic system?

Lever on the left of the steering column is how you raise and lower the lift arms. The oil is on the left side of the tract in front of the battery box. It has a dipstick to tell you the proper level. Good tractors. I've had both a wd45 and a wd. Wish I still had them at times. Make great square baling tractors with the hand clutches to stop forward movement for heavy hay slugs.

Due to the way you posed your question, it makes it hard for me, to answer it. The snap coupler is a mechanical bell shaped unit, which the drawbar snaps into, and with the drawbar removed, it also will receive machinery, that has a snap coupling hitch provided by the Allis Chalmers Co. These implements are what we call propriety implements. Several aftermarket 3 pt. hitches are offered, for your tractor, and most snap into the snap coupler bell. By using your snap coupler as a hitching point, either a 3 pt. hitch, or the drawbar, will then have draft control. As to what controls the snap coupler???? It is released from the implement by pulling a small lever close to the shifter, which is connected to a light piece of chain, which runs under the tractor, to the snap coupler latch. Now Draft control, is a different ball of wax, and can be best explained, by a manual, or a patient person, on the Allis Chalmers forum

Al, I forgot to tell you, that all you need to know about your hydraulic system, will be on a diagrahm, on the right side of your battery box, or again in a manual. It calls for 20 wt motor oil in the hydraulics, but I have used hytran in mine for years.

Allis developed the snap coupler to get around patents Ford had on the 3 point hitch, it is kind of a 3 point hitch turned up side down. As others have said Allis developed their own specific implements to go with the snap coupler.

One peculiarity of the hydraulic system was that it was low volume and high pressure compared to the typical system. If I remember right it was relieved at pressures of 3500 psi or so. With this kind of pressure you need small diameter, strong cylinders on towed implements to get the right balance of stroke speed and force. If you're not planning on using remote cylinders this is a moot point, however.

There is a rod that you pull to release the coupler. It has nothing to do with hydraulics or the hitch arms.
