I have an Allis Chalmers tractor that is either a WD or a WD45. the two are very similar and I have looked at pictures of them but I can't find one thing that is different. Does anyone know of anything that I can tell the two apart besides engine displacement? thank you

WD45 was first to have power shift wheels. I believe they were standard on the 45. Ed

WD (successor to WC) had power-adjust wheels as standard. WD45 had larger tires on rear than regular 'WD'.

'WF' continued in production and did not have power adjust wheels.

45s had a curved seat support, wds had straight one with a bend infront of the seat. 45 had slot adjustment for top of shock on seat, wd had one position. 45 had 3 rows of tubes in radiator, wd 2. Keep in mind that all of the differences could have been changed over the years, the best way to tell is by engine nos. and serial nos.

Another thing is if you have a straight shifting lever, then you have a WD. If a curved shifting lever, then probably a WD45 but could also be a WD from the last year of WD production, so the curved shifter isn't a sure way to tell, but the straight shifter is. Look at the serial number on the back side of the left brake housing. WD45 production began at serial number WD146607. A smaller number would indicate a WD and larger of course a WD45.

Easiest way is to look at the right hand side of the engine. The WD 201 CID has a large rectangular plate bolted on the side, WD45 226 CID "PowerCrater" doesn't.

WD tractor s/n below WD146607 on left rear (note the WD45 start at 146607 but also have WD prefix on axle). All WD45 have curved shift lever (but so do last of WD). WD motors start with prefix WD- and range from about 196000 to about 360000. WD45 motors start with 45- prefix and start a new series that runs up to about 100,000. 45 motor has no right side access plate (really that is easiest single thing I use though I have 2 WD45's - 1 with WD motor and 1 with WC motor that were no doubt changed after the fact.)

Today's Featured Article - Grain Threshing in the Early 40's - by Jerry D. Coleman. How many of you can sit there and say that you have plowed with a mule? Well I would say not many, but maybe a few. This story is about the day my Grandfather Brown (true name) decided along with my parents to purchase a new Ford tractor. It wasn't really new except to us. The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule. Now my grandfather had had this mule since the mid 40's and he was getting some age on him. S ... [Read Article]
