Very strange seal leak in my upper left hand side of the cros shaft. I had replaced the the seal this last winter and have got about 30 to 40 hours on it and hadn't had a leak until just recently. I have 10w -30 weight motor oil in it now and I'm thinking with the triple digit temps out here in Calif. could be vthe reason. Now once the tractor 55 oliver is shut off the leak stops. the little vent just under the seat is free of any such material to keep it from breathing. I'm not sure thought I'd just drive it some more. The level is right at full with the tractor running and the 3 point all the way up and the dipstick just sitting on top of the casting. Need a little bail out here Farmers, Thanks..
