TYM 474 automatic throttle

[Matune]

My automatic throttle quit working with the pedals. The mechanical throttle works great.

it’s out in the woods so I hate to haul it into the dealer who said, “I have heard of that happening, check wire connections to see if a twig unhooked something.”

so at this point I shall have to haul it in.

I guess I’m hoping someone has an idea....I could find no disconnected wires or loos connection s thus far...

i normally don’t use the automatic throttle anyway, buts it’s new so it should be working..,

If your TYM has the Kukje engine, then it should be all mechanical.

For the throttle, you should have two cables. One for the hand throttle and another one for the HST linkage.

You may want to look under the tractor to see for any obvious fault after tracing the route of the cables.

Yes, there should be a linkage from the pedals to the injector pump, the T474 shop manual is on the Facebook group if you need diagrams etc.
