Hey all, Im not new to the YT forums, since I usually hang out on the JD or Case area, but I am new to the Allis part.

Anyways, my uncle recently passed away from cancer, and left behind a bunch of tractors, including the one in the pictures. Im afraid I just dont know anything about this on other than we use it for snowblowing and the Hydraulics seem to be very selective as to when they want to work.

I want to order some manuals on the tractor so I can learn about it, but I'm not really sure what it is?? Is it a WD or a WD-45? I cant seem to find a serial tag anywhere. Can you guys tell me which model it is from these pics?

Any help would be appreciated!

If you have the Hydraulics set properly, the lift-rams will work as you would expect, and the "Hold" position is more of a "Feel" than a position.. With use, you will know when you are on that "Hold" position.. It may creep, until you get the feel of it.. Very good system, once you catch on to it..

WD chassis prior to mid-1952 based on shift lever - s/n should be on left side of rear end steel stamped into the flat area - but I can't tell from picture of tractor whether engine is WD or WD45 - it may have a WD45 engine - a common swap.

The 201 ci WD engine will have a plate bolted to right side of block full length of block. S/N on left side behind carb will start WD.

The 226 ci WD45 engine will have no plate and s/n will start 45-.

There were also kits to convert the WD engine up to 226 ci - so you would not know for sure without opening it up.

best, ed

It is definitely a WD- straight shifter, 1948-1952. Tractor serial number is on the left rear vertical face of the differential- not by the upper link hookup. Will start with WD- .Regarding manuals- The OPERATOR manual is a must for anyone to operate the tractor- tells ID of controls, oil capacities, recommendations, fill and drain ports. Hyd adjustments, etc. OP manual is specific to the WD or WD45. SERVICE manual tells by text and pictures, how to repair it. I&T AC-11 is the correct service manual for the WD and other AC of that era.

After another look....I see it has been converted to the Snap-Coupler system of the WD45. Fantastic! I"ll refrain from commenting on the 3ph.

Thanks Charles,

We are keeping them. We pull with 3 of them, including the WD, and just have fun with the rest. This is the only one I havent really worked on so I'm just trying to learn more about it.

A WD mostly identifiable by the straight shift lever. WD45 was curved. The foot operated clutch pedal not only stops movement of the tractor, it also stops the PTO, belt pulley and hydraulic system. If you want to just stop the tractor movement but keep hydaulics and/or PTO operating, then push forward on the hand clutch. (lever on right side of steering wheel). That was ACs answer for live hyd and PTO. The hand clutch can be slipped all day long with minimal wear. Handy when blowing snow or chopping or baling where you might want to slow tractor movement but keep the engine at full throttle with the PTO running.

Looks to be a straight WD. The serial number is on the back of the rear end just below where your top link attaches to the tractor

Today's Featured Article - Major Problems - by Anthony West. Following the aquisition of the two Fordsons to my collection I found that I was struggling to move them about. I had considered the possibility of driving the "F" to and from shows but anything other than local rallies was totaly impractical due to its sedate pace. I had also considered buying a landrover and trailer, but the price of a ... [Read Article]
