break-away coupler on a Farmall 350

DonO-MN · Dec 21, 2011

Guys,
I"m wondering how and where the break-away coupler for rear implement cylinder was attached to the back of an F350 tractor with a fast hitch? Also, the hydraulic ports attached to the battery box connect to the fast hitch cylinder, so I"m assuming the break-away coupler hoses are feed from the hydraulic ports below the gas tank, but which side? How were the hoses originally routed back to the coupler? Where the hoses rubber or steel? Ideally, if someone had an original setup still in place, could you post some pictures of the break-away coupler mounting and the hose routing? Thanks for the help!

AFAIK, the first valve always goes to the rear remotes. The lines are steel across the platform on a 450 but rubber on a W-400 Also rubber on a 660.

When I need to see original components and options, I go to my parts books or the CaseIH on-line parts books.

Hi Wardner,
Near as i can tell, the first valve always feeds the fast hitch, via the steel lines on top of the deck. I have looked at my parts book, but the book shows parts for the 300 and the 350 for various years and various options, etc. it is not clear to me what parts to use for my exact situation.

I remember a extra block bolted to the bottom of the right side hydraulic outlet block. Steel lines run from it down the right side under the deck lid overhang. Rubber hose was made to the lines near the end and went to the coupling that was mounted above the pto to a bent bar that attached to the top cover.

Don, I have a 450-D with a factory remote setup. It does have an extra block on the 2nd right side valve that the steel lines connect to. These steel lines go to the back and become hoses about 3 feet long to which the couplers are attached. I would assume the 350 is similar but with maybe shorter steel lines. I can take a couple of close-up pictures and email them to you if you would like.

But one thing that I wonder about is how they did it on a 400. The 400 uses the 2nd valve for the fast-hitch cylinder that is used for tilting. My dad bought a 400 with a fast-hitch and 3-valve. But when my dad needed a remote for his chopper, the dealer ran hoses to the back from the 3rd valve. This allowed full use of the hitch cylinders and remote. So not sure how a factory remote would have been installed on a 400 with fast-hitch. Anybody know? Al

Some had steel jumper lines with a block on each end that went from the left side outlet block to the right side block with just the passages on left open to rear lines. Least thats what I remember if equiped with 3 valves. Blocks have plugs that can be removed and orings seal blocks to each other.

The inset box is bracket for a 300 or 400, with a cast smooth rear end housing
The T shaped one is for 350 450 with the rear housing that has a flat with four bolt holes.

There is a "junction block" that bolts to the right hand remote under the fuel tank, the metal lines screw into those and run to the rear.
You can see the entire factory set up in this photo.

Anyone else notice that the breakaway couplers are connected to the same block as the tilting cylinder for the fast hitch? Guess they just inserted the pin and locked the tilting cylinder to allow the use ofthe couplers.

D Slater, the picture sent by rhtx55 is exactly like I have on my 450-D. But if I put my spare remote on my 400, then it looks like I would have to pin the tilting cylinder. So probably just keep it like my Dad had it back in 1955 with the hoses connected to the 3rd valve. Still use the 400 for my back blade and remote for my pull plow to plow the garden. Al

AJB-830 · Dec 21, 2011

That's why I never put my spare remote setup on my 400 as I didn't want to pin the cylinder and couldn't figure out any other way to do it. So guess if it was ordered from the factory, that's what you had to do. Al

extend the tilt cylinder completely, set the stop collar all the way towards the cylinder depressing the lil stop button, and that would keep it from extending or retracting then the remotes would work seperately.

DonO-MN · Dec 22, 2011

That would be great if you could email a few pictures. Still not clear on how the steel lines connect to the right side block. Thanks!

(quoted from post at 23:34:57 12/21/11) extend the tilt cylinder completely, set the stop collar all the way towards the cylinder depressing the lil stop button, and that would keep it from extending or retracting then the remotes would work seperately.

Nah, the pin opens up a valve in the cylinder that lets the oil flow in the "retract" direction.

You'd only be able to operate the remote cylinder in one direction, because the oil would just flow through your open tilt cylinder in the other direction.

The only way is to pin the hitch so the tilt cylinder cannot move in either direction, WITHOUT pushing down on that pin.
