The first 2 numbers in the last set of numbers on the engine should be the year B&S made the engine. I doubt the engine is original because it has recoil start and looks like an aluminum block. Have seen cast iron blocks only on the V-Series. Unless Simplicity supplied a bare tractor with no engine and MW supplied their own. That would also explain the odd tractor model number. I think this is what they did with the Midland produced tractors. MW sold many Wisconsin and Clinton engines on their own so their buying power made it an advantage.
Did you ever get the manuals to download from Simplicity?
Thanks again for your continued interest in this old tractor and for trying to help me out.
I did get a response to email request for info from Simplicity yesterday.
They attached a digital copy of an original manual for it.
For additional information for the group, there was a hand written note at the top that denotes this unit was indeed a 1959 and a Model H in Simplicity colors. They went on to say that the Wards numbers are their model number system applied to a given unit. The 990161 was the Simplicity Mfg number for this particular model of Montgomery Ward tractor.
So, I guess that I've got an H Model made in 1954. Now as far as motor goes, the manual says that it should be a B&S 5 3/4 H.P. Mine has a B&S 8 horse motor on it. The motor numbers are 19 0432, Type 605 01.
I will now keep seeking additional information for the H Model and how to use her. I have changed a few of the implements on and off, and use the tiller the other day and could not believe the power that this old tractor has. You have to be careful, or that old girl will drag you out across the yard before you can get to the controls to stop her.
Any suggestions as to the best gear/throttle speed, planetary gear position, etc. to till under? Any special techniques to use?
Another question I have is since I don't have the original engine, should I go ahead this winter and restore, thoroughly clean, and repaint this old girl?
What would any of you guys do with her?
Thanks for your help.
