Ok please be gentle, I just acquired a toro 44" commercial mower yesterday. It has a 14 HP Kohler commander on it. Now here comes the idiot part..... I cranked the sucker and ran it for probably 3 or 4 minutes and it runs great then and only then do I decide hey idiot youd better check the oil. Anyways it was about 1/2 to 1 quart low so I drained it to see how much it held other than that and it looked like a good bit more. My question is do you guys think I have hurt anything? I mean after I made sure it was the correct amount like I should have done before it still ran excellent. Are these things built to where if you run them a little low like that it wont hurt them. Thanks for your help. Dale BTW the mower was given to me I know TORo aint the best but free is always better!!!!!!!
