rigoletto, does your mower have a hydrostatic drive?

hmmm, not sure what that is. I guess not, as I have not seen that mentioned anywhere in my manual. Also, if that required hydraulic fluids, etc, do not have any of that.......no fluids other than engine oil.
 
manual: "Model Series 660 thru 679 transmatic lawn tractors"

Mod 13A4667 F118

Years ago, I talked to a MTD tech and he said the 5th, 6th, and 7th digits in mod # is the model. So above, thats mod # 667.
does that help determine if its a hydrostatic?

Sorry, 3 maybe 4 safety switches on this one. Two 4 terminal safety switches (part number 725-1657A) and 1 reverse switch (part number 725-1643) and then if you look to the right hand side of the wiring diagram you will see a lead not attached to any part. On the seat breakdown they list a seat switch optional ( part number 783-0611)

meanwhile, Riv's homework- I got 2 swicthes a;lready- gonna find the other 2.....
 
heres 2 pictures: first pic- loose yell/blk wire is dangling. This I think is the seat safety wire, but not sure where it attaches. BUT, this shouldnt interfere with starting, right? This is a good thing if rider gets off, and engine dies, right? Its been so long since this ripped off- I cant remember how it works. Evidently, this probably didnt contribute to the nion start problem. I believe. Still, I want to find where it hooks up.....

Supposedly, in this pic, theres supposed to be a safety switch near the F-N-R lever shown here, but where is this switch? Thats why I posted this picture. See the lever in back? It just goes to a C type spring. I dont see a switch, let alone wire that would atach to it.

Yellow/blackstrip is part of the safety switch circuit and needs to be hooked up. It runs from the seat switch and one of the two 4 wire safety switches you have found. Also, have you checked that fuse???
