What is this big lever on the right?

[uruiamme]

What does this foot lever (or is it a hand lever) do? It doesn't seem to do anything to the PTO or transmission or 3-point. I am at a loss here. Maybe something to do with hydraulics? Someone please help!

Diff lock.

Right wheel brake used as an aid for close quarter RH turns. Probably a similar one on the left side.
If pushing said lever down with your right heel proves in operational and the tractor has some age on it it would indicate worn out brake shoes that need replacing.
My 2 cents

You are a little short on details about which tractor.

If 4wd, it is likely your front-rear differential lock as suggested. Used when your wheels start slipping to make all your axles drive together.

If not 4wd, and as it looks much larger and higher up than my heel-lock lever; it could be your hydraulic 3 point level limiter in a very low position. As this lever is also on the lower right side by your leg.

Diff lock.

This, differential lock. Use with your heel, not your hand. When it is engaged it locks the rear axle for more traction (ie to get unstuck). DON'T lock it down with the wheels spinning. Press in clutch with left foot and wait till wheels stop, while holding down clutch press the diff lock with right heel and hold it down, let clutch out.
Next time you clutch it should disengage on it's own (you will see it pop back up). You won't be able to steer very well with it engaged.

Being 4wd or 2wd, doesn't matter. It's a rear diff lock. Very few compact tractors have front diff locks and mostly are European models. Landini, Lamborghini, Same, Deutz are a few examples that offer electrically actuated front and rear diff locks.

That is true. I should have aid more attention and erased that part when I revised what I wrote.

Wow, so a differential lock.... no wonder I couldn't figure it out on level ground and with good traction. I've never heard of such a thing attached to a lever that you can engage or disengage. I guess there's no rice paddies within a few hundred miles, so it's likely not going to get used. Thanks! And this is a Mitsubishi D1600, like my profile says.

Wait until you find mud/ice or dragging something stubborn around like a plow.
