1820D mystery lever

[p6464]

Thanks for everyone's help in finding a decent tractor. Ended up buying an 1820D from Stan Hoye along w/ numerous implements of destruction! I've already moved and leveled about 60 cuyd of fill and only almost tipped over once! What a success!
Anyway, on the right side of the seat, there are two levers next to each other. One controls the raising and lowering of the 3 pt hitch. What does the other one do? I'm sure it must have something to do with the the hitch, but what? It doesn't do anything that I can tell, so maybe it's not working. Stan thought it was something to do with leveling a tiller but had no other details. Any help?
Thanks!

Is it connected to the hydraulics in some way? Or to the rear axle (engages the rear 540 PTO?) As you can see, I am TOTALLY unfamiliar with your tractor, but am willing to offer my wild guess.

Peter, 1820D is an awesome machine.....

The controller that does nothing is most probably the OEM lever that operates the Tiller via linkage that is gone from your tractor.

Seldom (if ever) does a Yanmar imported to the U.S. come with the original (or any) linkage, tiller and sometimes wheels/tires. Tractor yards in Japan separate the equipment from the tractor and do the same during containerization. The majority of importers (dealers) do their best to keep weight (costs) down to a minimum including batteries, most fluids and anything else that is not related to make the tractor run correctly.

Mark,
Thanks! So if I understand correctly, it's not hooked up to anything and even if the linkage were there, it wouldn't work do anything with whatever tiller I've got? What's to "operate" on the tiller other than engaging the PTO? I'm just curious now what it originally did, even if I can't use it. Of course I can let my two year old sit there and pull and push on it while I make loud, gear meshing sounds and he screams in delight!

The control is identified as a draft control but I think most U.S. operators wouldn't reconize it as such.

After a lot of study, making inquires and such, I've come to the conclusion it's only purpose is to control the depth of the Yanmar tiller that was typ part of the tractor setup. On my tractor there is some linkage close by the left lift arm for the 3pt. A long flex cable connects to this and the other ends connects to the tiller drag flap. The position of the drag flap moves all this linkage and thus lifts/lowers the 3pt to control depth. In some ways it's operation is similar to the operation of a draft control one finds on U.S. tractors and how they control the depth of rear ground engaging implements.

My 1820 D also has that extra lever. Many American tractors have a lever by the lift lever and is a draft control. The draft control only does something if the 3 point hitch assembly is pulling something. It effectively sets the depth of the plow if one has one. If the plow goes deeper, it pulls harder so the draft control raises the plow to get the force as set by the lever. Thus the draft effectively controls the depth. I imagine that the tiller works the same was as to pulling resistance and depth of the tiller.
