tractor. 3 #1 Posted 9 hours ago Hey yall. I have a wheel horse b80 with a kohler k181 and with starter generator. Im unsure of the year of the tractor. Does anyone by chance have a wiring diagram for one. Thank you in advance. Share this post Link to post Share on other sites
Sparky-(Admin) 25,059 #2 Posted 8 hours ago The B-80 was produced from 1974 to 1977 with the K-181. But it never came with a start/gen motor. The wiring will have to be somewhat custom. 2 1 Share this post Link to post Share on other sites

Sounds like you have a "FrankenHorse" Yup, pictures from several angles are needed to select a best-suited schematic. But here's some light reading on the S/G subject... disregard the corny artwork..... The last file is rather large.

Ignition switch will definitely be different. Here's one with a solenoid to get you started. 1 Share this post Link to post Share on other sites

ebinmaine 78,356 #7 Posted 3 hours ago Very interesting project. I've been a fan of the Starter/Generator systems for several years because of the unique noise at startup and good overall dependability. Looks like you may have a 1974/75 ish B80 with the 4 speed. Someone has transplanted a mid 1960s S/G 8 HP engine in there. There's an S/G belt cover missing from the side of the engine. A few points of interest. This tire MAY be low on air. The blue rectangle is where the battery would set. The yellow oval can be a point of contact between the Starter and the battery. Watch for that. There's a shelf that goes here in blue. parts are easy enough to find. I may have one if ya need it. That's where the "B80" decal would have been. The tag just below that would have the serial numbers to identify the tractor. This circular piece in yellow appears to be the old coil holder. Not sure where it belongs on your "modified application". Share this post Link to post Share on other sites

The ignition switch in the diagram Jim posted is a 103990 which is readily available at auto parts stores or big box stores like HD, Lowes, or Tractor Supply.

Not sure where it belongs on your "modified application". Thank you for the pointers. I just bought this a few weeks ago. I bought this with another one that has the original engine in it as a parts tractor. The guy I bought it from was also trying to turn the two into one but had no time so he sold them to me. I do know about the tires I do have some just need to put them on the rims. The parts tractor has the shift knob, and the coil holder was a little to small so I used a different one. The gas tank holder/shelf I took off to get to the pto safety button easier. Thank you for the tip on the battery though. I did find a john deere 110 wiring diagram because they have the same kohler engine, and I will try to merge the 110 and the b80 diagrams to hopefully figure out how to wire it up.

Not saying they do or don't... just that they may be different types and that can present issues. Share this post Link to post Share on other sites

Or the switches are? It's the switches I'm concerned with .... If a "normally open" switch is placed in a circuit that requires "normally closed" that's a potentially serious problem.

You may be headed down a rabbit hole with little hope of success. I would suggest you go with the simple diagram Jim @WHX?? posted unless you happen to have the John Deere harness and are reasonably knowledgeable on wiring. If you can post the JD wiring diagram we can help you as much as possible if that is the road you decide to go down. Share this post Link to post Share on other sites
