I am confident the Custom 3rd Function Kit is offered for it, but those are listed by loader model number.
Let me know yours and I'll double check. You're welcome to call me to discuss. 828-464-1200.

It's the 1525 loader.
Massey produced those a couple of different ways.
Is the loader valve on the tractor or on the loader?

I took my Wicked Grapple off to use forks the other day. When I re-installed the grapple today, I could not connect the hydraulic hoses as the grapple side was under pressure. When I loosened a pipe fitting on the grapple, to relieve the pressure I could make the connections.
What is the correct way to relieve the pressure when disconnecting the grapple?
The pressure inside the cylinders and hoses on your Grapple is dependent on the outside temperature difference between when you disconnected and when you are trying to reconnect. Hydraulic fluid expands with temperature as do most fluids. So you may need,to relieve the pressure as you mention. On the tractor side, shut down and cycle all the valves to relieve pump pressure to the tank.I took my Wicked Grapple off to use forks the other day.

Goeduck in our part of the country storing out of the sun is easier than those less fortunate members living elsewhere.
Now to the problem at hand. Cycling the 3rd function valve with the engine off at disconnect and again at re connect helps a lot but if the cylinders are still under pressure the protrusion from the male fitting can be rapped smartly on a hard surface to relieve the pressure. There is an expensive tool made to do that. Don稚 remember the name of it but it was discussed and cussed on this forum a few months ago.

Any chance you have something for Santa to bring me?
Hey man, it looks like you've received some good advice.
To summarize. It's a good idea to unhook the grapple in a position with the cylinders either fully open or fully closed. The grapple style will really determine which of those positions is best.
Also, depressurize your hydraulic system before unhooking and before rehooking.
Here is a video with Ted which explains said depressurization..

Travis nailed it, lots a great advice from all who replied - thanks everyone. So, Travis which position is best for the 60" Wicked Grapple?
It may have been fluid expansion because I am pretty sure that I de-pressurized before disconnecting the grapple. The pressure was definitely on the grapple side of the fittings. We did have some cool weather and now it is warmer again.
Being a chemist, I am very familiar with fluid properties, but did not think that the pressure build up would be that much. However, this is a closed system full of an incompressible liquid - duh. :shocked:
Yes sir. The Custom WR Long 3rd function kit is offered for the 1525.
For installation, you'll need a power beyond adapter from Massey/Agco, which will need to be sourced from a dealer.
Part #s SL103119 and SL103143. They should be inexpensive.
Feel free to call me if you want to order. 828-464-1200.

If it's a 60" Wicked Root Rake Grapple, I'd store it fully open and face down. Cylinders will be retracted and lid will be bottomed out.

Like this, fully open..

If it's a long bottom 60" Wicked...fully closed.

Those are the positions which will prevent gravity from building pressure. If you're a chemist, I"m sure you've forgotten more than I ever thought about learning concerning expansion due to temperature. :laughing:
