I don't see one in the schematics, but...

I have the 917.25961 SS/18 Twin tractor.

I don't have the correct manual, but I do have one for each of the 25960 and 25191 tractors that are extremely close. I cannot find a safety switch on either schematic that operates with the parking brake, but I suspect mine may have one.

I have been using a pliers to jump the solenoid on this tractor since last winter when the key switch stopped working on me. I checked the two switches I found, and both of them operate perfectly.

Now yesterday, when I went to get an old A/C unit out of my son's garden shed, I decided to let the tractor do all the work and hooked up the yard trailer to it. Jumped on the tractor, hit the switch, and VIOLA! It started with the key!

The only difference I could see was that I had the parking brake set while I hooked up the little trailer. I rarely use the parking brake, because I always try to drive off with it still set.

Are these tractors commonly equipped with a safety switch on the parking brake?

The parking brake lever does NOT have a safety switch on the ss18.

The safety switch is deactiveated by the lever on the brake/clutch shaft when the pedal is depressed.

(There should also be a safety switch for the PTO lever that starts the mower deck or other attachment.)

The parking brake works by "locking" the brake pedal in the on position. To set, push the brakes and hold while moving the lever forward.

I think your safety switch may be worn or needs adjusted.

If you need instructions about how to test the safety switches, please email or PM me.

Thanks

Let us know if it works.

Hey

The reality is use what works. If the parking brake allows it to start, then use it. (Try to remember to release it after starting.)

I have a "new" SS-18 also. I'll try to post a pic soon.

Well here it is.

It is NOT running. Engine won't turn all the way over by hand. (I think it might have a broken rod?) It does have a hood, but it was loose (broken hinge) so I don't have it place right now.

Maybe it overheated from the LIGHT coating off dust.

I'm in the middle of swapping the b48M onan engine from my GT-18 hydro to this frame. I'll post some pictures in my other thread as I progress.

It always good to know you're not the only one who wants to keep a 30-40 year old tractor going.
