Rockshaft to SCV conversion

[donk6950]

I have a JD 855 1995 that uses the rockshaft to lift the mower deck. How to I convert to using the SCV to lift the deck. My older 1994 had this feature and I prefer the SCV to lift the deck.

Welcome to TBN

Probably some TBN member will know exactly what to do, but in the meantime others may be able to help if you would post some photo's of just what you have now, i.e. quick connects and SCV valve setup, FEL ?

Additional information: This tractor has an SCV but it does not lift the mower deck. How to I make the SCV lift the mower deck? I also use a Material Collection System mounted on the 3 pt hitch which is controlled by the rockshaft. I need to keep the Material Collection in the UP position while I am raising and lowering the mower deck while mowing. Any help is appreciated.

Do you have a front end loader on now using the SCV joystick ? And connected with the two quick disconnects ? Do you remove the loader when mowing?

I'm not sure what a loader/no loader would have to do with it. Seems to me you need to study the geometry of the current mower support brackets and decide if it's possible to add the bracketry to support a hydraulic cylinder that will effectively do the job. The SCV can then be used to operate the cylinder(s).

Harry, just attempting to learn what the OP presently has to work with to accomplish his goals. Hope to better understand his frustration and dilemma.
Or maybe it is just me not understanding..

There was a 'Kit' which is showing as NLA (No Longer Available).

You may find a New Old Stock pack in a dealership somewhere. Maybe ask your dealer to do a Parts Search ?

The notes say:

"KIT CAN ONLY BE USED ON TRACTORS EQUIPPED WITH SELECTIVE CONTROL VALVES"

It may be possible to purchase all the components individually:

That's the hydraulic parts.

This is the Rockshaft & lift arms set you'll need also:

You may consider modifying/adapting the hydraulic lift kit from a more modern 1025R (And maybe 1026R) machine.
It's a single hose set-up which bolts onto the side of the chassis.
It is what I'd call 'side-loaded' working on one side of the mid-mount rockshaft and wears unevenly as well as breaking the bracket due to 'flexing'. I've strengthened two kits with gussets to transfer stresses to the frame better.

Now that seems like some usable information. Even if the kits or parts are not all available, there should be information (diagrams and dimensions) to copy and fabricate what's needed.

Yes, I have a loader and I installed it with the quick disconnects and it worked fine. I do remove it for mowing.
