I have a new grapple that has worked correctly on a New Holland Tractor for the last 2 seasons and a lever under the seat is pushed to the left to open and to the right to close or vice versa as I really don’t remember which direction opens or closes. I connected the hydraulic line to a JLG G5 18-A telehandler and per the JLG manual; holding a button down and rocking the joystick to the left opens the grapple and holding the same button and rocking the joystick to the right closes it. What I have is when I hold the button down and rock the joystick to the right, the grapple opens and when I let go of the button, the grapple completely closes (it should stay open). Do you think reversing the hydro lines at the grapple would solve my problem?
On the JLG telehandler, the auxiliary hydraulic circuit is usually set up for continuous-flow tools (like hydraulic augers or sweepers). That’s why you have to hold the button – when you release it, the solenoid closes the circuit and the oil returns to tank. The result is: the grapple “relaxes” back closed instead of holding position.
Reversing the grapple hoses will only change which way it opens/closes with the joystick. It won’t fix the issue of the grapple not holding position after you release the button.
What you really need: A diverter or auxiliary valve with detent/hold function on the telehandler, so flow stays engaged until you move it back. Sometimes JLG telehandlers can be configured with a “clamp” or “auxiliary grapple” mode that holds hydraulic pressure when you release the button. You’d want to check in the operator’s or service manual to see if that option is available.
