Hello Everyone, just looking for info on some unfamiliar controls. What is the lever left of seat above the turtle rabbit that seems to increase the hydraulic pressure? Also what is the knob under seat that points in an upward direction that says open close?

Welcome aboard. These forums are a wealth of information and most folks are happy to help.

If you don't already have the operators manual, please get one and possibly the Workshop manual.

The forum search isn't that good but you can use google by adding "site: orangetractortalks.com" after the search terms.

I don't have a clue what your asking as I don't have a L3570. But as they say a picture is a worth a thousand word. Post a picture of what you are talking about. Circle it if you can.

Without a picture I am guessing it is the adjustment for the speed go the 3pt hitch up/down.

I don’t think there would be anything that increases hydraulic pressure that would have a lever.

The knob under the seat will adjust the (lowering only) speed of the three point hitch. It is basically closing (slowing) or opening (faster) a valve that lets the fluid flow out of the lift cylinder.

Would that lever be the manual shuttle shift lever? Forward / neutral / reverse.
I just downloaded the manual, it appears that you are correct, Thank you. I have a turtle-rabbit lever, forward neutral reverse lever at the steering column, and a gear shifter shifter. I still don't know what the shuttle shift lever is used for.

Messick's has a video that does a good job showing what the open/close knob does.
If you search videos for how to use a box blade those will show why it can be important to set this correctly.

I am not as sure as you are ! lol. I located a picture on the net that showed the shuttle shift lever next to the hi low range lever ( turtle-rabbit) which is a different layout than your pictures. Is your L3750 a two wheel drive or 4 wheel drive version (DT).


In your picture the fact you have an empty gate next to the mystery lever, could that be the lever for rear remotes? Often times when rear remotes where added as a factory or dealer option there was extra gates depending on a single rear remote versus double rear remotes.

Hum, looks like this is unresolved. When the lever is pulled the main hydraulic line appears to be pressurized.
The reason I posted this morning was due to my front loader bucket raising slow and working very hard. (Shaking) I'm trying to understand the controls before I troubleshoot the hydraulic system. I'm guessing clogged filter or bad pump.

I do believe that lever on the left of the seat runs a remote valve on the rear.
If the lever is not springing back to center then there is an issue as it will put the Hydraulic system into bypass.
And yes the round knob is for three point drop speed.
