I recently changed the oil and filter on my 2007 Sears tractor. I put in 64 oz as instructed. The tractor ran about 45 minutes, I mowed the lawn. No problems. 3 days later I went to mow again, and after a couple of minutes, it sounded like a gunfire and a massive amount of white smoke filled the air. It is dead now. I get nothing when I turn the key.
My tractor friend diagnosed my problem after listening to what I had to say in less than 2 minutes. I used my manual for the amount of oil. The manual is incorrect, the proper amount in written inside the engine cover. I definitely added too much....... the key was dead, because he said, too much engine oil, I was going up a small incline which pushed the oil into the crackcase(?). That made it blow...... the blow,...blew Crap and smoke onto the key sensor on the lower side of the engine. He just wiped that off. I drained the extra oil out, and all is well!!! He saved me the price of a new tractor. Thank you all.
