Almost 50 hours on the tractor and I managed to break the casting that holds the pin for the swivel. I must not have had the pin in all the way. the backhoe is also leaking from the bank of fittings and valves under the platform. I am going to do the 50 hour service in the next couple of days and will tighten everything. if that does not work I will call the dealer. Bummer .. I did tackle three ash stumps and a spruce stump this afternoon ash stumps are not spruce stumps the hole was so deep I heard Chinese music by the time I got the stumps out.
