Hi everybody, Im a 2nd year owner of the 1025R -with a 54" mower deck, front loader and back hoe. Great piece of equipment and enjoy every minute I'm on it! Today I noticed something for the first time, when my mower deck is raised all the way up it moves up and down about a ½" but its non stop in a constant rhythm. It actually makes the tractor bounce a little. The 3 point hitch attachment arms also move and if I hold the hydraulic line anywhere I can feel it pulsing. If I lower the deck down to cutting position it stops completely or if I take the mower deck off and raise everything back up it still stops. It only happens when the mower deck is on and in the raised position. I've checked the hydraulic line connections, took them apart a dozen times and reconnected, so its definitely not the connection, but it does seam like a hydraulic issue. Does anybody have any ideas? Really appreciate any help. Thanks.
