disc mower setup / use and tractor lift arm questions

I know I use the top link connection bar to change the angle the mower sits at, do I adjust it so the blades swing level with the ground?

My tractor (JD 5510) has 2 levers which control the rear lift arms. The both seem to raise and lower the arms on the 3 point. I can't figure out the difference between the levers - maybe one is pressure type and the other a float or something? Any help in ID'ing the difference on the levers and how to use them to correctly adjust the mower when it is lowered to the ground for use appreciated!

Likely you have a position/ draft control on your tractor, and one lever sets it for position (you'll want all the time) and the other direction is draft (only useful for plwing using a 3pt plow). The regular lever moves the 3pt up & down. That would be _my_ guess.

My Ford tractors have 'Dual' control on them. This allows a semi-mount plow to work just like a full 3pt plow in draft mode - moves the 3pt up and down on it's own as well as the rear cylinder, phased in with it. Takes a special hyd cylinder, as well as setting several levers & knobs correctly in the cab. I was told 20 years ago that moving one of the knobs at the wrong time could hurt things in the hydraulics.

Now, I've never used this 'feature', but I'd sure buy a manual, or visit a dealer, to fully understand these knobs & controls & levers _before_ I'd go throwing them back & forth 'just to see what happens'.

Bad things can happen sometimes.....

So, you are getting real good advice to GET A MANUAL to know how to operate your tractor.

The fact that you don't know isn't a big deal, and you shouldn't be critized on that.

I have never used a JD 5510 so my suggestion is to call a John Deere dealer.

Well then, your help is appreciated - I'm sure you can tell me how do they work?

I've run this tractor for about two years now, but everything has been pull behind attatchments (bush hog, haybine, tedder, etc).

Have a guy with as much "experience" as you who came to look at it with me and wasn't sure how they worked either.

He knew he was going to be ugly and he did it anyway.

Don't know about the levers but some good person on here will. If you don't ask you don't learn.

Nothing online that I could find on the Kuhn disc mower, but I read the JD disc mower manual since they are fairly similar and hopefully can go from there!
