AC Power Lift Traction Boaster

I'm looking for any information about how the AC power lift functioned. It appears to be an inverted 3 point. Did it have depth control? And how did "Traction Boaster" work?

Thanks for anything that you can provide.

I have a 55 WD45 that was abandoned for ten years. After a lot of work it runs great. When ever I ask the local guys about the traction booster on my tractor, I get a lot of static. They say that it never worked. Just a gimmick. Some say it worked half assed because it would plow at different depths. It is good to hear some real info on this feature. I guess if you dont understand something you tend to run it down. I am very proud of my WD45. I might go out and buy a plow just to show some people what she's got. The old guy who sold me my fence row special swears it use to pull a 4-14 plow all day long. Thanks for the info, even though I wasn't the one who ask the question. Dennis

On the early WD's there was no snap coupler hitch but the traction boost worked the same. You removed the drawbar (as in the snap coupler) hitched the implement to the pin that the drawbar was previously mounted to, connected the lift arms to the implement. Drop the implement (plow) into the ground, then raise the hyd control lever just short of raising the implement itself. As said elsewhere, the harder the pull the more lift thus more weight on the rear wheels. Works like a charm!!! These tractors, when working with the boost will out pull just about any tractor of their class of the time and quite a few heaver than their class. As said before, full instructions in the manual.

Well.. almost, Dave. When I used mounted equipment on the old WD, I left the drawbar attached to the tractor. The pins that allowed you to set the drawbar height were removed, letting the drawbar float up and down. A pin went into the equipment and through the drawbar. There was also a pin (well.. almost a clevis-like device) that attached near the front of the drawbar.

I made it sound complicated, but it really wasn't. Some people I knew actually claimed that this first traction booster connection method was easier than using the snap coupler, since the drawbar did not need to be completely removed.

The AC Snap-Coupler was not simply an inverted three-point. It pulled from the bell, mounted forward of the rear axle. The sensing device (spring and linkage up to the hydraulic pump) tranferred weight of the load to the tractor's rear wheel by applying a slight lift to the mounted or semi-mounted implement through the lift arms. The amount was controlled by the position of the lift lever which was also used to raise the implement. If you set it too high, the implement simply came out of the ground. The gauge under the gas tank (on WD45) or dash on D series, etc. gave a relative reading of the amount of lift, or gain in traction. Control of the -entire- hydraulic system is detailed in the operator's manual, or on the battery box of some models.

The idea was to provide a little lifting force to the implement when a lot of pull by the implement was being put to the tractor. In a non-booster tractor this increase in pull to the tractor made the rear wheels spinout/slip. In a traction booster tractor the lifting force applied to the implement resulted more in an increase of down pressure on the rear wheels because the implement was working in ground that resisted the implements raising any at all. The harder the ground, the harder the the pull, the harder it is to raise the implement, the quicker the rear wheels slip/spin out. I guess you could think of it as magically appearing set of wheel weights when the going got tough. The simple mechanics are a spring loaded draw bar mechanically linked to the hydraulic system. If the system is in good condition and rigged correctly things worked real well.
