I verified they are filled yesterday, and they shipped the couplers overnight which was a bit unexpected. I told him about the fluid being low and he offered to reimburse the cost of getting some, I told him I'm not worried about that as I know I will need to add some after the grapple and flail is all hooked up, I just wanted to let him know the service guys should look before it goes out the door.
On to the good part, the tractor is fantastic. Only got to spend about an hour in it last night with the grapple and flail on, but already was able to move some brush and start cutting the 4-6' tall scrub. Need to adjust the cutting height and get some seat time today.
