Hello all, Today i had a new employee i recently hired do 3 of my lawns as i was taking the day off, on the second lawn he calls me up and tells me that my 21" Toro Proline (Commercial) Mower all of a sudden let out a puff of white smoke and a backfire with "actual fire" and then it stopped. So he finishes the job up with the backup mower and once he comes back i try to start the mower and it starts, however it shuts off. Upon closer inspection i notice that its spitting out what appears to be burnt oil out of the exaust type thing in the front, next thing i notice is the oil case is overfilled (the oil was up to the middle of the dip stick) he then tells me he put more oil because it was "backfiring" when he turned it off, but i had already told him in the past that to make it stop backfiring when you shut it down is to run it in "slow mode aka turtle mode" for about 25 seconds and then shut it down. So should draining some of the oil and letting it run for a while fix this problem ? or should it be taken to the dealer (they charge $85 per manhour to check the problem). Im thinking this should fix it but im not 100% sure, so i thought some of you might have had this problem before. Do any of you guys know the easiest way to drain the oil, there appears to be no plug.
