The TR10D is 8.25HP the TRA10D is 10HP the rod and pistion are different as the TRA has a longer stroke to accomplish the extra 2HP

 

If your steering wheel dosent have molded hand grips its a 1966, if it has the molded grips on the sides its a 1967-1969

One other way you may be able to tell whether it is a TRA1D or the TR10D is to check it there appears to be a compression release moving the exhaust valve up just a hair during the compression stroke.  If your remove the valve cover ( the cover on the side with the breather tube) you should be able to look in and see if the exhaust valve tappet only moves during the exhaust stroke or if it also moves up just enough to open the exhaust valve on the compression stroke. If it has the compression release it may be a TRA10D and if it does not it may be a TR10D if the camshaft is still original and you can still turn the engine over.

Thanks guys for all your great input I tried to add marvel mystery oil through the spark plug hole on the 1050 and all that happened was the oil drained out of the intake manifold, so that isn't going to work. I did the same thing on the TR10D in the Bolens 1000 that motor has a carburetor on it so the oil probably did the same thing but I could not see it. So I guess I will have to pull the heads and expose the top of the piston.

 

Stew I won't be able to check the compression release until I can rotate the crank shaft.

 

I took some pictures of the steering wheels on the 1050 and the 1050 parts tractor. Both steering wheels are different but have finger holds on the bottom of the steering wheel.

 

Take a look and see what you think.

When you get the head off, you can measure the stroke (distance from highest piston position to lowest).  The TR10D has a 2 5/8" stroke and the TRA10D has a 2 7/8" stroke.  Both models have the sam bore diameter -- 3 1/8".

Wisconsin also had several different crankshaft variations on the output shaft for different OEM specifications.

Stephen,

I would be very grateful if you take some photos of the process when you expose the heads of your 1050 as I got to do something similar to my 1254 sometime. Cheers

Andrew
