Today was a very bad day! I had to leave on an emergency and left a couple of employee's to finish mowing 40 acre park! I came back about 2hrs. later to find that almost nothing was mowed. I asked what is the deal, and they said that my bladerunner 27hp diesel was knocking, and my 32hp diesel bladerunner just quit! I am thinking what is up with this because I have had zero breakdowns with either machine and my 32hp has over 3000hrs. on her and the 27hp has just under 700. I go over to start my old reliable 32hp and it's just locked up! And I am thinking what in the world. So I go and start the 27hp up and sure enough it is knocking badly. OH NO! I am saying to myself with a few other words. So I load up the machines and take them to my dealer. I just got a call from him about 7:15 tonight and he tells that he got the 27hp tore down and it needs one rod bearing and two rod bolts. So I asked what in the world caused it to do that. He then tells me that the mower has been filled up with straight gas in it! Oh great now what? My dealer has the parts in stock for it and said he should have it ready tomorrow! Which is good news. My 32hp is going to need a little more help which is bad news. I quess I will have two less employee's tommorow! I am sure thankfull that I have a good dealer to take care of me in times like this!
