Bx24 - drive forward/reverse pedal safety switch location

[richardbro]

Hi y'all
Got a 12yo bx24. The safety switch gremlins have been pestering me the last few years. Under-seat safety switch loose wires, pto-engagement switch full of crude, etc... Seem to have all those mastered up to now but the forward/reverse safety switch is my current torture. Jiggling the backwards pedal usually works but lately even this method has it's limits (especially when an incoming thunderstorm is looming).

Anyone know the location of the backwards pedal safety switch? I poked around in there recently but failed to locate something that looks like the other safety switches...
What's a good sledgehammer size to rap it with?

I do not believe there is a safety switch on the HST rocker pedal. It is "sprung" to return to the neutral position when released, that is the "safety". Are the pivots free of crud and lubricated so the pedal returns freely to the center/neutral "default" position?

On my "rocker" L3560/HST the wires attached to the separate forward and reverse solenoids under the operating station can work loose or be pulled off when Bush Hogging through brush higher than 14". I would check those wire connections. Be sure the wire and solenoid contacts are clean, so current flow is not inhibited. Make sure contacts are reasonably tight.
(Your comment on incoming thunderstorms leads me to speculate your problem is electrical.)

After twelve years some minor maladies must be expected on any tractor.

Yes - the return-to-neutral isn't what it used to be when new. I do grease the zerk though. Maybe there's an adjustment I can do. I figure there's a safety switch there somewhere because it has to detect the neutral position electrically somehow to cut off the engine.

Our BX2660 has a neutral switch to make sure the pedal is in neutral when you try to start it, or get off of the tractor.

Thanks - that's what i suspect the bx24 is doing. Just need the location of the thing to clean it out

Well I guess like other neutral safety switches it's located on the lever apparatus under the tractor, you'll need to get down/under and have a look. The bx25 and 2660 are possibly the same so download a manual from kubotabooks.com and heve a look there to help if you can't find it. To make things easier you may have to remove the rear wheel, but I suspect with some hard stretching you may be able to get to it without, but that's just a guess.

Guess I'll update this old thread. There IS a safety switch on the HST rocker pedal, located behind the read right wheel. I recently had some time so I removed the back and cleaned out 10 years worth of crud back there. That's when I found the switch (sorry, no pic). I clean some crud around the switch but the actual fix required unloosening 2 screws that hold the switch body to a sliding rail and advancing the switch about 1/4 inch. Also did he same to the PTO safety switch.

Work fine now...

Fine machine - will be selling it this summer when I sell the farm

Yes, you are correct!
Using a hydrolic floor jack, raise the back right side.
Remove the back right tire.
For safety, use a jack stand under the axel to support the tractor.
Have a friend push the hst pedal to see the switch location.
It will be a grey switch with a push button.
Place a heavy block on the forward pedal to provide additional work space near the switch.
Remove the two retaining screws with a Phillips head screwdriver.
Be careful to try and hold onto the back nut plate when removing the second screw or will lose it and have to purchase a new one.
Now disconnect the switch from the wiring harness. You may need a flathead screwdriver to help separating them.
Now comes the fun part...
There is not enough room to hold the nut plate in place and also screw on the new switch. Some have tried applying grease to the plate hoping it will stay in place. I tried this method numerous times with no success. So here you have two options that will work.
Option1: purchase a pack of clip nuts from you local auto shop and use these instead of the switch plate. Great if you ever have to do this again.
Install the clips, then insert the new switch into the wiring harness. Use the two screws to attach the switch going through the clip nuts. Slide the switchbox all the way forward, even with the metal plate.tighten the two screws. Remove the weighted block from the pedal and check to see if the switch engages and disengage as needed.
Option 2: this is for those who want to keep everything original on the tractor.
You will use one screw to attach the switch to the nut plate(use back left hole). Screw just enough to have it secured so that it won't come apart. then place the switch in front of the steel plate with the groove. Make sure the nutplate is behind. Then using the second screw, insert through the right hole and attach the switch. Do not tighten completely. Now remove the first screw(back left). Slide the switch forward even with the steel plate and tighten the screw. Now put the screw back into the left hole and tighten. Now, like before check the pedal to makre sure alignment is as needed.
I hope this helps!!
