Darned Sharp looking Sears, you guys put some real time into it.

Welcome to the forum! Nice looking tractor. Model #'s will help a lot on figuring things out!

That's a beauty, sorry I can't help with specs without the numbers.  Even then, I may only be able to find part numbers, not sizes for you.  Someone more knowledgeable here can, I am sure.  They sure have helped me whenever I have need assistance.

Sure pops into the forum with a hoot of a question huh??  If no information is available take a string and wrap it around the pulleys and mark/measure..  You may have a few trips to the store for he thing but it should get ya going iif you can't find the model##

From the looks of the dash, foot boards, and hood, I'm suspecting that is a '67 SS12, looks like you got it clean up very nice.

You can look on the motor, on the mounting base front left, kind of under the flywheel/carb area, there will be a number stamped in the oil pan right above frame, that will give you horsepower rating of the motor.


Here is a couple sites that still sells blade that will fit the 42" Sears decks. Guuy I know bought them, he was using them to "bush hog" some high grass and was very impressed.








Belts... I list different sizes as I've seen many people use both sizes with success, there was some belt length differences as Sears changed pulley sizes related to motors used. I also think it may be due to aftermarket, off shelf different brands, etc. I buy Kevlar belts from TSC for my needs.

I think your 12Hp may take the 81"  engine to tranny belt and probably the 101" engine to deck.


Starter/gen - 3/8"X 33"


Main drive, engine to tranny- 1/2"x 81, 82 or 83"

Deck pulleys belt- 1/2"x 92"

Engine to deck-  5/8" x 101, 102 or 103"
