Just bought a JD 140 71 to 74 H3 rear drum brakes. I need a photo of the free wheeling valve. I think its the one w/ the black round knob that protrudes thru the deck pan. Do you turn it counter clockwise to allow it to be moved? The older models show a t bar valve that you turn clockwise. Thanks.

Turn it clockwise to release pressure.

Congrats on the tractor. Clockwise sounds right to me. The older 300 series use the same trans. setup as the newer 140's.

As Trav1s said, turn colckwise until tight to make it freewheel, counterclockwise until tight for power to be applied to the wheels. That's what the Operator's Manual says. I have it and the Service Manual as PDFs if you want them.

Sorry for the short response earlier - I saw the post in between engagements.  The 120/140/300/312/314/317/316K all share the same design.  Sometimes those relief valves stick close and open.  I used a bit of WD40 or PB Blaster on them before I used the knob.  Also, if they stick open the tractor will "pulse" when the hydro is engaged.  I just went through this with my 120 after a year of tear down for rebuild/repaint.
