Connect the hydraulic hoses to the tractor

Connect the four hoses — two from the valve, two for the bypass — to the tractor remotes, and set the valve's remote to continuous flow. Full Automation Kit only.

  • Full Automation Kit

The Full Automation Kit uses two pairs of tractor remotes. One pair feeds the valve, which Ditch Assist® controls. The other pair runs the bypass hoses, so you can still move the implement by hand with the tractor lever. That makes four hoses at the back of the tractor.

Before you start

  • The valve fitted with its hoses and mounted (Fit and mount the valve)
  • The implement lowered to the ground
  • The tractor engine off and the key out

You need: the two hoses from the valve's P and T ports, the two bypass hoses (Valve Bypass Kit) and a piece of cardboard for checking leaks.

Time: about 10 minutes.

Four hoses at the back of the tractor The tractor's rear remote couplers, seen from behind. Remote 1 takes the two hoses from the valve's P and T ports; this is the remote you set to continuous flow. Remote 2 takes the two bypass hoses, so the tractor lever still moves the implement by hand. Four hoses in all. drawbar Remote 1 valve hoses, P and T continuous flow Remote 2 bypass hoses all four run back to the valve
Remote 1 takes the two valve hoses (P and T) and runs on continuous flow. Remote 2 takes the two bypass hoses. Use any two free pairs of remotes on your tractor, and remember which is which.

Steps

  1. Relieve the hydraulic pressure

    With the engine off, relieve the pressure in the tractor's remotes the way your tractor's operator's manual describes. Do this before you plug in or unplug any hose.

  2. Plug the implement's hoses into the valve

    Plug the implement's raise and lower hoses into the two implement couplers on the valve. Where those couplers are on your valve: Bucher or Rexroth.

  3. Plug the two valve hoses into one tractor remote

    Plug the two hoses from the valve's P (pressure) and T (tank, the return) ports into one pair of remote couplers at the back of the tractor.

    Remember which remote this is. It is the one you will set to continuous flow.

  4. Plug the two bypass hoses into a second remote

    Plug the two bypass hoses into a second pair of remote couplers. With this remote you can move the implement by hand, without the app.

    Check it: tug each of the four hoses. None should come out of its coupler.

  5. Route the hoses with slack for turns

    Hoses stretch when the implement turns, and parts near the hitch can catch each other on a corner. Leave a loose loop of hose at the hitch, then cable-tie the hoses so they can't drag.

  6. Know the continuous-flow setting

    Whenever you work with Ditch Assist, set the valve's remote to continuous (constant) flow, not float, with enough flow to move the implement. The valve then raises and lowers the implement as the app needs.

    How fast the valve reacts is set in the app. See Controller settings.

  7. Check for leaks

    Start the tractor and put a little pressure on each remote. Hold a piece of cardboard behind every fitting and look for oil on it, never use your hand.

    Found a weeping fitting? Shut the tractor off and relieve the pressure first, then tighten it.

  8. Test the bypass remote

    Work the lever of the remote with the bypass hoses. The implement should go up and down. If it doesn't, check the two bypass hoses are fully plugged in on that remote.

  9. Turn hard left, then hard right

    Drive slowly in a tight turn each way while someone watches the hitch from a safe distance. No hose should pull tight, pinch or rub. If one does, stop, shut the tractor off and re-route it with more slack.

Hydraulic hook-up with the bypass A simplified hydraulic diagram with numbered markers. 1: tractor Remote 1, set to constant flow and not float, feeds the proportional valve: pressure into port P and return from port T. 2: a one-way check valve on the pressure side means oil flows one way only. 3: tractor Remote 2 connects to the valve’s two bypass ports, so the implement can still be worked by hand with the valve connected. That makes four hoses to the tractor. 4: the control module drives the raise and lower solenoids on the ends of the valve. 5: two hoses run from the valve to the lift cylinder on the implement. If Raise makes the implement go down, swap the two solenoid connectors and never reverse flow at the tractor, because the check valve then stops all movement; if it lowers but won’t raise, turn up the flow on Remote 1 and check it is on constant flow, not float.

How the oil flows:

  1. Remote 1, on continuous flow (not float), feeds the valve: pressure into P, return from T.
  2. One-way check valve: oil pushed backwards through the valve gives no movement.
  3. Remote 2 runs the bypass hoses for hand control.
  4. Control Module drives the raise and lower solenoids.
  5. Implement hoses run from the valve to the lift cylinder.

Common mistakes

  • The valve's remote left in float instead of continuous flow.
  • Flow turned down too low to lift the implement.
  • Reversing the flow at the tractor to fix wrong-way movement.
