What are the differences between the straight WD and the WD45? Just years and minor engine differences? Also, what are the values on each of them? Just curious.

Thanks

You ask about the other hitch options but no one mentioned the original WD hitch. This was a simple swinging draw bar with a big coil spring where the forward portion connected to the tractor frame. As the pulling load increased on the drawbar the spring compressed and actuated the linkage to allow weight transfer from the implement to the rear wheels. These were used with the early AC implements for this tractor. One of the many was the "pick-up" plow. I remember many times hooking a buried stone with the plow, compressing the spring and then the plow would jump over the stone and give you quite a jerky surprise! The WD is esentially (depending on soil) a 2/14 plow tractor, the WD-45 a 3/14. When the snap coupler's came out most WD's were converted to the snap coupler. I will say that particularly in plowing that weight transfer to the wheels was one of the greatest things AC came up with, along with the power adjust wheels.. Seldom did you stall a WD engine for any reason and when that plow dug in and the wheels started to lose traction the weight would come on and she would keep right on going.

Sounds like some good patents!

Did all the WD's come with power adjust wheels, or were some equipped with pressed steel?

Some WD's had a Inspection Cover on the right side of the Block. Wd45 did not. Prime difference Cosmetically is the Gear Shift. Wd-Straight, WD45- has a curved to the left Gear shift.

Thanks for the good replies! That's exactly what I wanted to know.

On the WD45 they came out with the diesel, correct? Is that an engine to stay away from, is the gas better or more reliable?

I was reading up about a snap coupler hitch. What is the other option besides this hitch? I wasn't familiar with this at all. I'm told it was a patent to put more weight to the rear wheels?

As far as the styling, these tractors are both basically the same, right (as far as lines and sheetmetal are)?

Finally, what could you compare this tractor to in the MM and IH lines? Just out of curiousity.

Thanks

The diesel WD45 is quite collectable because it is rather rare, for that reason as well as expence to repair, I`d say it`s not really a user tractor like the WD45 gas is.

The snap coupler hitch which all WD45`s and most WD`s either had or were converted to, is a great system. In many ways better than the now standard 3 point. Fergson/Ford got the jump with the 3 point, which works well enough and others followed their lead. It is very simple to adapt a WD/WD45 drawbar and lift arms to use 3 point equipment. There are several different conversion kits that will allow you to use 3 point equipment, or simply drop the drawbar and use snap coupler equipment too. I really like the conversions made by Cross Mfg. and sold by many different people.

The WD and the WD45 look the same at a distance, even touching the tractors many people don't know how to tell which is which. I'm sure WD45 decals on a WD have fool lot and lots of people over the years.

Thanks John!

Another thing i'm curious about is the traction booster gauge. How is that operated, and what does it truly measure? Anyone have or know of a pic of one somewhere?

Thanks

The traction boost gauge measures hydraulic pressure that is being imput to your lift arms by the traction boost system. You can buy new gauges if you get a bank loan or you can buy fake gauges that look real but don't work, maybe without the bank loan. To be honest I don't see the need for a gauge unless you are restoring a tractor to show. You can almost always tell by the way the tractor sounds and pulls, if the traction boost system is working and having to work. I'll bet fairly few working tractors still have a gauge that works, I know I've had several tractors with bad gauges but the system worked fine anyway. If you want a new gauge, here is a link.

WD45 diesel used the Buda engine- gas is much more reliable and cheaper to repair. Snap-Coupler was invented by AC for easy hookup of mounted equipment, and provided for weight transfer of the implement to the rear wheels. Basically it senses loss of traction and slightly raises the implement to gain that weight to the rear wheels. Relative amount added was indicated on the Traction Booster gauge. Snap-Coupler bell can be added to WD tractors as well- many have been converted. WD45 is comparable (slightly smaller) than IH M tractor. Power is close but weight is much less at around 4400 lbs.

Nope- been called a variety of names, but never Jeff. Bet I lived here 20 years before the grain elevator man quit calling me Jerry.

Ok. There's been another guy on here from MN that uses his initials for his username, and his first and last initals are J and S. Sorry about that! :)

What region of MN do you live in, JMS?

Central part of God's country- hour nw of metro. Actually, like most any other state- lotza pretty areas around. But bil from AZ visited recently after many years, and couldn't get over the green cropped land, nothing un-used, the well-kept farms and towns. Simply pride in where you live- the heartland of America.

OK, up by the Ramsey/Lino Lakes area. I picked up a truck up there years ago by Lino Lakes.

There are many exceptions to general value rules! In my area, useable not restored WD`s and WD45`s are quite common. WD`s run $700 to $1200 and WD45`s are $900 to $1600. Wide fronts usually bring more than narrow, and loaders add a couple hundred dollars as sometimes do 3 point conversions.

The WD had around 30 Hp and the WD-45 ran around 43 Hp. The WD was 201 Cu inch engine and WD-45 had 226 Engine. The 226 had 1/2" longer stroke and the same size bore.
The WD's had straight cut gears in the transmission and the WD-45 had angle cut gears.
WD had a 2 disk hand clutch and WD-45 had a 3 disk hand clutch. WD's usually had a magnito ignition and the WD-45 had a distributer.
WD-45 had a bigger carburetor and different manifold.
WD-45 had wider rear rims and tires.
