Indicator Light for Differential Lock on RTV

[Ohio_Pawpaw_Grower]

Has anyone designed an indicator light that reminds you that your diff lock is on?

I have only had to use my diff lock a few times but I am trying to avoid the dreaded "grenade effect" to the rear end or trans.

It should be possible to rig an arm-actuated switch that is clamped to the diff lock pedal. But before start, I wanted to see if its been done.

Thanks - Tony

I rigged a “parking brake applied” indicator lamp for my Kubota tractor because I can’t seem to remember it until I recognize how much power has been required for the last 100 yds. Doh!

Anyway, if you need a “reminder you’re and idiot” light.... THIS product was found at O’Reillys auto parts and it’s exactly the thing because you can drill a 5/16” hole in the plastic panel and pop it into the hole.... AND...the little LED lamp FLASHES BRIGHTLY AND CONTINUOUSLY when power is applied to it. Here is a pic of it in it’s pkg ($6) and it’s the lamp in the upper-right of my tractor panel: (CLICK on the Pic-Icons to see the photos)

Doesn't your diff lock disengage automatically once you remove your foot from the pedal? Mine does either immediately or within a few seconds.

Unless you also use the Diff-Lock Pull-Knob.

Gotcha. I'm pretty sure I have that knob but don't recall ever using it. It's on the side, above the bed dump lever, right?

Correct...when I start a long climb on a wet service road, I usually lock the diff and pull up the handle. Most of the time I remember to take it off but all it takes is seeing a nice buck or some other distraction and I forget. I will try that LED George, thanks.

One of the pleasant surprises of that little lamp is it BLINKS continuously.... if it’s activated and WITHIN YOUR FIELD OF VIEW.... you cannot ignore it.

It's ordered, thank you. Now I will just have to figure out best way to trigger it with the motion of the diff lock pedal. Shouldn't be too difficult.

How did you activate it?

My Kubota tractor has a lever to pull up when the brakes are applied to lock the brake pedal in the applied position.
I welded a short bracket which I’d drilled to accept a Normally Open button-switch. The switch is depressed when the lever is pulled up onto it’s locked position. The light is powered by the “hot” side of the key-switch. If the key is ON and the parking brake lever is pulled up (which activates the switch) the little lamp blinks-blinks-blinks.......

Brilliant. The pics are too small for my old eyes to view but you've explained it in principal and it sounds pretty simple. Thanks.

OK.. WEll, go to THIS KUBOTA TRACTOR FORUM and you can see better pics and better description of how I did it:

Parking Brake Reminder (Caution-Lamp Installation)

I am bad about not noticing I’ve got the park-brake set on my M4700 and after driving it awhile, pushing in the clutch only to realize it STOPS immediately...obviously the brake is still-applied. :mad: So I decided to create a “Park Brake Warning” light. I used a piece of steel bracket or...

Outstanding - thank you.
