Treadle pedal issues

BubbaJr · Jul 13, 2019

Recently my B2650 has begun to creep forward with my foot off the pedal. Then last week I had a heck of a time to get it to start until I got the pedal centered, and it's getting worse. I checked my owners manual and my WSM, and the only thing I could find was " If the tractor creeps by itself, see your dealer".

Is there an adjustment for the treadle safety switch, or do I need to replace it?

I don't have an answer, but wanted to jump in here to see what others say in case mine would develop this.

If the tractor is creeping forward then it sounds like you are looking for a pedal neutral adjustment more than a safety switch adjustment.

I agree, or possibly a neutral spring adjustment. There may even be other possible causes, like a branch stuck in the linkage. With the mower deck on, I can't see up under there to diagnose the issue, and the deck is such a PITA to remove and put back on, that I'm trying to avoid that until I have a much better idea what gremlin I'm chasing.

Thanks for opening my eyes to other possible issues.

Look over the linkage real good and lubricate anything that seems dry. Several things can cause it to hang up. The damper (which slows the return of the treadle back to center) can stick, or it's linkage can stick. The cruise control linkage (which ties into the treadle) can stick. The brake will have a linkage which ties into the cruise control (to disengage it) and that can cause issues.

Years ago I had this problem on my B2920. I finally realized that due to lack of lube, every time I pushed the brake pedal, it was moving the cruise linkage and that eventually interfered with the treadle. That one took some detective work. Once I lubed everything it was fine.

Often there is an overlooked zerk grease fitting on Kubota pedals concealed by the floor mat

To cure the creeping issue will probably cure the safety switch issue! You probably just need some lubrication.

There is a zerk under the treadle that needs grease. You can get to it from under the tractor.

I went out yesterday and lubed up the linkage for the treadle. Then sat in the tractor with the engine off, and pumped the treadle for a while. It seemed to get a little better, but I'll know better the next time I use it. Also the last service I did on the tractor I did lube the treadle zerk. BTW I now have 300 hours on the tractor.
