floating the three point

[Jvilljoe]

I'm new to tractor ownership and I'm trying to figure out the right way to operate my tractor. I own a Jinma 224 and if I understand the "manual" right, the correct way to float the three point, is to adjust the "stop" collar to allow the TPH to lower as far as possible and to keep the control lever in the lower position, not to return it to the stop position while operating the tractor/implement. Is this the correct way?
Thanks in advance!

I don't think you have down pressure on the 3pt (be surprised if you do).

Whatever works would be okay, if you are happy with the results. But to me, all the way down with the control would be 'float'.

Where ever you stop the lever, the three point will float up from there. The lever sets the lowest position that the lift will go.

There should be TWO stop collars. One is to set the highest position you desire the lift arms to raise, the other the lowest. The upper is more important on a 200 series Jinma, since the hydraulic piston has a very strong tendency to over-extend. The cylinder O-ring and wipers are destroyed in the process, .

The only down pressure is from gravity, and the 200 series has no draft control. The TPH will float - albeit slowly - whether you want it to or not.

Greg,

On our KAMAs, we have the two levers. For the sake of ease, the inner and outer levers.

1 What lever should be used for simple up and down?
2 What lever do you adjust the stops to prevent over lift?

I understand that one lever is so you can leave the lever in a position, thus make a max down location. I could imagine when useing the yard box you may want to drop quickly to a preset max depth.

My old Ferison TO-20 was up or down and even then would slowly go down on her own.

Since the original poster asked a Jinma question, that's why I tried to clarify he has no draft control.

WRT to your KAMA question, the longer of the two levers (outside) is the draft control on my mine. Set desired penetration depth with that one - as in blade/rake/plow. Then use the shorter (inside) for position control.

I tried in vain to get some use out of those ridiculous wingnuts that supposedly limit the levers' range of motion, but they aren't worth crap. Out of necessity, I've reverted to the "visual method".
