Rear electronic SCV sometimes sticks on 3520 cab

shortthrow50 · Sep 6, 2012

Have 2012 3520 cab with electronic rear scv. Toggle switch is located on joystick. Sometimes when i tilt back my hydraulic toplink with a load on it it sticks. To stop it i have to hit the switch the other way. Anyone else notice this issue. I know im not the only one out there that has seen this. I did a google search and saw another fella named hanson had this issue and tried new switches but didnt fix issue. I know for sure my switch is not messed up.

I know you say that but you hit the opposite direction and it stops so it is obviously making contact in the first direction after you release the button. My 3rd valve on my 05 3320 is lever driven so I cant test out for you. I would clean the switch for sure.

My 4120 2011 model with eh 3 rd scv does the same exact thing. The heavier the implement the less it does it.
I haven't figured it out yet myself.

Ok so i assume everyone has this issue and just havent noticed it yet or hasnt posted. i did some more searching and it seems this has been an issue for quiet some time for many people. Tractor is going in in a couple weeks for some add ons so ill bring it to their attention and let you know what they say. thanks dusty
also, noticed as well that for some reason it is load sensitive. Only does it depending on the weight of whats attached

Try swapping the hoses at the SCV outlets and see if it has the issue when the switch is pushed in the opposite direction.

Had a Kubota that did the same thing, all the time, drove me nuts. Kubota ended up buying the tractor back.

My 4320 will stick once and a while (2-10 times) It looks like they all do it...
