l47 in limp mode, no codes.

[Vlach7]

Where would be the best place to purchase the WSM for my tractor? 800hrs, recently cleared a code for when the RPM drops to low, #P0336. It has now no foot throttle response. I believe this would be considered "Limp Mode".

Send me a pm with your email, I will attempt to send you the link for the wsm. Thanks to NIW for that!

Sent to your email, hope it came through ok.

THANK YOU, already printed it up. Thanks, NIW.

Check your air filter

Check your air filter

Thank you. This was a sudden onset; I clean my air filter all the time and for the most part only tractor after a rain. after I study the WSM I will let you all know what fixes it, hopefully not a trip to the dealer for an ECU reset.

Merry Christmas to all, I am blessed, went back out to try the manual or hand throttle and not the foot throttle. Every single thing seems normal now hopefully it doesn’t come back, thank you all.

So ... Was it just a quirk?

Or did you do something to it?

Not sure, couple weeks ago I had that P0336 code come up about lugging it or engine going to slow RPM and I cleared it the same day I cleared it. I changed the oil in my front drivetrain and put a new hydraulic filter on, then two weeks later which was a couple days ago. It would not rev with the footpedal above 800 RPMs and I thought that would be bad when it’s time to regenerate because I won’t be able to get it to needed RPM, would run in low medium or high at 800 RPM, got the WSM and couldn’t really figure anything out but figured that I could use the manual accelerator that increases the RPMs and I did that today and it raise the RPMs with that and then also the foot pedal so I am not sure if it will come back but it appears fix for now.

I am a little confused, there is no foot pedal accelerator. The foot pedal is the HST control. The only time it increases rpm is if you have auto throttle turned on, on the control panel. Is it possible that was on previously, and got turned off somehow?

 

[Vlach7]

I’ve only had it five years and maybe I did have a senior moment but it’s working now and I will be more aware of that auto throttle, yes, the HST pedal was not working

 

[Vlach7]

I do not recall, turning a auto throttle on or off.

Thanks, you were correct, my auto throttle was off.

Glad you figured it out, and it was something simple!
