Last year I bought the SGC0554 Land Pride grapple and the 380-289A third function valve kit for the BX2380. Shortly before taking it off for the winter, the curl while opening or closing feature stopped working. All the functions still work and I can still open or close the grapple while lifting. Just not while curling. ItÂ’s still under warranty, but the dealership wants me to bring it to them to check out. IÂ’m in the middle of logging cleanup at our place and donÂ’t want to loose the use of the tractor right now. I cannot find anything online that deals with this specific problem. What troubleshooting procedure would you guys recommend. It was originally installed at the dealership.
