Safety Switch? Question

[thecoopers]

Our B2920 Hydo Kubota has experienced chronic starting problems for many months. We have been putting up with it, wiggling things to get it started.

It seems as though I have localized the starting problem to a part located under the forward/reverse area of the deck (where your feet rest while driving),

There is a part underneath the deck that has two wires coming in from the end facing the back of the tractor from a wiring harness up under the seat.
This part then has a a round metal body then towards the front of the tractor and then a rubber boot covering a round metal piston type rod part (3/8") that can be pushed backwards. The end of the rod seats against another rod coming from the front of the tractor that seems to have some linkage to the forward/reverse pedals.

When I push in a screwdriver where the two rods meet and the piston of the safety switch is pushed in (towards the back of the tractor) and leave the screwdriver in, the tractor will start every time.

I think I can loosen the safety switch and move it forward which will force the piston "in" and maybe then the tractor will start like it is supposed to.

Should I do this? Will it hurt anything? What is the purpose of this part? Does anyone have any thoughts that would be helpful to me?

Thank you,

Joe

If the safety switch in question can be unpluged, use a jumper to bypass the switch and see if it starts easier, thus indicating the switch is faulty. Will do no harm to bypass safety switch.

Other than defeating the safety mechanism and allowing the tractor to move when not expected.

First off, I did not advocate permanently disabling the safety switch, only a way to check it.

Second, how were we able to survive for many, many years before the concept of safety switches was even available? Yes, they became available because of some mishaps, but all in all, they still can be operated safety.

P.S. Safety switches don't necessary mean the tractor is safer, only that stupider people can operate them more safely.

The saftey switch under the seat is put in place incase you fall off the tractor it kills power to the engine. My thing is if you fall off the tractor you're pretty well up Shitts Creek!

I didn't mean to sound like a smart Alec. I was with the post up until the "won't do any harm" part.

The clutch safety switch on my tractor is currently bypassed. I'm not real happy about that. The previous owners did that and also clearly never used the seat belt which was rusted solid, so I have these things on my mind.

I'm new to operating a tractor and don't really have any adult supervision. I do stupid things all the time like try to start with the engine kill pulled out. I'm probably one of those stupider people in spite of my education, so I appreciate the additional precaution measures built into the tractor.

So ... putting the debate of pros and cons of safety switches aside, does anyone know if the switch can be adjusted? Would spending X number of dollars to purchase a manual tell me how to adjust the safety switch? What should I do?

Thanks,

Joe

While I do not know for sure, I would imagine that the clutch safety can be adjusted. You need to crawl under there and look at how it's mounted. Once you have eyes on it, the method required to adjust it should be obvious. You should be able to easily accomplish this without a manual.

Secondly, the manuals are worth every penny that you'll spend. You should have the Owner's Manual, the Workshop Service Manual and the Parts Manual. You can get a Parts Manual download at no charge.

Thank you for your reply. Where would a person find the free download of the parts manual?

Since I helped your thread drift a bit off topic, I'll try to be as helpful as I can

Following is the best site I've found for free online manuals. Unfortunately I don't see anything for a B2920. There is a parts manual for B2910HSD:

Did you try the "Search" feature ----- ??? I'm guessing not.

Just wondering if this is some kind of variant of a neutral safety switch? If you adjust it make sure in the end that the tractor is actually in neutral when you find a starting position. just sayin..

Messicks displays online parts diagrams for a wide range of Kubota equipment.

I agree with the previous poster on the value of both the owner's manual and workshop manual.

Was there any follow up on the switch? I had to wiggle mine to start the tractor. My dealer says there is going to be a recall on this.

That's funny right there. I have to agree.
