Hi I have a 2005 cat 277b. Last time I used the aux hydraulics were about a month ago. I was using my grapple to move a few logs around. I just bought a new brush hog so I began to use it this morning, It worked for about 5 seconds and then stopped, I tried to go the other way on the thumb and the same thing happened. Now when I try again nothing happens, I tried to press the continuous flow button below the horn button and do not hear any relays. So far I am at the point to where I hooked the grapple back up and now it moves it just a little and then completely stops, I have to turn off and turn back on the machine to get it to move a little again. So now I have a grapple that will not even work and I am assuming my continuous flow is not working. I am hoping someone on here could help with this issue. Thanks in advance
