Removing Aux Hydraulic Detents - Kubota M7040

[ctc1111]

I have several Kubota M7040 tractors (model years between 2009-2012), all of which we run rear mount snow blowers on commercially. Each machine has the two auxiliary hydraulic circuits near the 3pt hitch. One circuit runs the chute rotation, the other runs the chute angle up/down.

Since my operation with these machines is so specific, I would like to look into removing the detents on the hydraulic controls. It seems either the flow is not enough, or it is locked into place and needs to quickly be pulled out of place before the chute over rotates. Its just a slight ergonomic complaint I, and the operators have.

So, my questions:

1. How can I remove the detent in the control of the 2 aux circuits?
2. Will it have any adverse affect such as the lever flopping either way when going over bumps and activating the hydraulics when not intended, or even machine damage in some other way?

Thanks for your help

Can you show some pictures of your valves.

If you can get to the detents, you can deactivate them by removing the detent assemblies from the valve. Most are little springs and 2 to 4 little steel balls.

I agree with J_J on disabling the detents by removing them If you're referring to factory rear remotes then you need to remove parts keys O & U at the bottom of the photo.

Look at parts W, and G.

O and U may be the load check valve.

Yep you're correct I was looking at photo incorrectly. I had in my mind the block(parts key c) attached on the top of valve body when in fact it attaches to body on the opposite end of the handle Sorry for oops, what was I thinking?

Here's a YouTube video on how it's done on a Kioti DK40. I know it's a different tractor and your valve location will be different, but the guts of it should be similar, so this might help a little at least for understanding what type of surgery is required. I still need to do this on mine, but it looks really simple.

Thank you for the reply on this everyone. Is that breakdown diagram the actual valve for my tractor? As of writing this I haven't looked it over yet, possibly the reason I'm asking..

But anyways, I will attach a photo of my valve stack that has two aux hydros by the 3pt hitch. While I'm posting photos, I'll put up one of some tractor candy from last year.

YES that's the parts photo of your tractors valve
