912h allis repower with 1972 briggs 12hp

Recommended Posts


Your 12 hp motor has the starter/generator, does it not?  If so, then the regulator terminal (in the picture) labeled 'Battery' goes to the ammeter and then on to the battery.  I am repowering a 7119 with a Briggs Vanguard.  I simply bought a couple of roles of 14 gauge wire and some terminal ends and started over. 

Harnesses?  Harnesses?  We don't need no stinking harnesses.  (apologies to The Treasure of the Sierra Madre).

He still needs  a grounding ignition switch and why buy one when the original is there.

I agree, but the grounding feature of the ignition switch simply grounds the kill wire from the coil and is independent of the ammeter circuit.  Or are we talking about different things?

anyone here got a good schematic of 3310v wiring graffed engine onto my 912 and need to hookup my ammeter and headlights. help!!!

The best I can help you out is for starts I am guessing you have the sister tractor Simplicity 7112, product number 1690473 similar to your 912 and to get it running with what you have in a Briggs powered version you would need a 7010, product number 1690204. You can download load both operators manuals, they should both have wire diagrams and compare the two.

When I have done a swap from kohler to briggs, i have found it easier to throw everything away and start over. I like to use the schematic from the earlier landlords. I throw away all the safety switches and add a starter button...I saw zippo do this years ago and have done it to my own machines. Simple and easy...

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time
