Nope. Read your manual. :laughing:
On our old IH2500b we had the lever that raised and lowered the 3pt hitch. Where ever you stopped it, it would stay at that height until you moved the lever again.
Then there was a lockable stop so you could set the depth (how far down the lift would drop) and return to that depth each time with ease. So, you get to the end of your row, raise the implement, turn around, lower the implement back to the same depth and continue.
I considered the lever the position control and the adjustable stop the depth control.
Then there was the draft control.
If the implement in the ground started to gain resistance, the rear tires would start digging in, which would make them go down, which would make the implement push against the top link. The top link was connected to a rockshaft, which would activate the draft control, which would raise the implement, which would decrease the resistance to the ground from the implement, which would make the tractor not have to pull such a load, so it would gain some traction, stop digging in and move forward, which would make the top link stop pushing on the implement, which would stop pushing on the rockshaft, which would turn off the draft control, which would lower the implement back to the depth in the soil that the depth control was set to and off you go.
There was a sensitivity adjustment on the draft control, which you had to adjust for implement and soil conditions.
