I sold my not so old BX2380 to my son and grandson. They bought a house in the town north of us. They had a big Martin bird house on a steel pipe. Last year a nasty windstorm blew it down snapping the pipe off about 2" above the ground. Well they forgot about it and today he was mowing and hit that pipe stalling the tractor completely. He took it out of PTO mode got it started and backed off the jam point. He tried to re-engage the mower and it would not go. I haven't looked into it yet and was wondering if there is a shear pin that might have taken the heat. Anyone else have this happen. I know where EVERY rock, stump, hole, or any other machine busting boogieman there is in my yard and work accordingly. Any ideas?
