So i'm investigating the engine replacement option as well, and have come across a 12hp Briggs pulled out of a Craftsman (unknown year).

 

Are all the 12hp Briggs vertical shaft engines equivalent? It looks to me like the 12.5hp engine was when they shifted to the twin cylinders.

The later one holer 14-18 OHVs might fit without much modification(longer block). Shaft diameter and length are the only thing that are critical. It seems the smaller 8-12 hp L heads are a little harder to find in good condition. Not sure if it is a design issue or they were abused more

when you say 14-18 you mean the larger displacement 14-18hp engines?

 

The engine I'm looking at would be replacing the 12hp Briggs in the Ford LT12H. I haven't looked at it in person, but from the picture it looks the same.

 

Are there different 12hp models? How do I determine if it's an L-head?

L heads are the flat heads. The OHVs are the overhead valve engines they used in the newer cheap stuff that is ragged out by now. Engines are usually in good shape (other than needing valves adjusted), but the LTs are junk. They are easier to find and in better shape than most engines made 25+ years ago. 14-18hp single cylinder engines are the most common.

Ok so it seems to me that my tractor has a 12hp Briggs L head and this other engine is a 12hp ovc out of a craftsman

I think I'm better off tearing into mine and trying to get it running

Seized doesnot mean broken. If the tractor gods are smiling it may just have heated up and gotten stuck if the oil level was too low. Pull the plugs check the oil and put a bar on the crank and see what it does. Just a friendly thought. Good luck with it!
