Rockshaft

I'm new to this so take it easy on me but how do I use the rockshaft on my 1949 john deere A?

Dummy plugs in the powertrol and PTO turned on, clutch engaged.

Excellent, but you also need to push the PowerTrol handle
forward or backward to make the rockshaft move.

Move control handle forward to raise & rearward to lower. Rockshaft requires load to rotate correct direction to lower.

Forward to raise and rearward to lower.

Also; you need the weight of an implement on the three-point to pull the arms down, no power down. Just power up..

i have a late 1949/early 1950 model A ,
and i know its easy to forget, but you need the pto turned on,
for the rockshaft to work, i believe

PTO engaged, clutch engaged, Lever forward to raise. Two replies here have said it needs weight to lower. The rockshaft will return even without arms on. Pretty sure there's a torsion spring on the rockshaft.

One more thing.

Make sure the Metering screw on the left side of the Powr-trol is turned Out 2 full turns for rockshaft operation.
