Why are you blaming Tor for an oil change bill. If you just had the oil changed that would be a little high. Did they do anything else? Spring tuneup, plugs, oil, oil filter, air filter, plus sharpen the blades? What is their labor rate, $80.00/hr. Let’s see, parts $40.00, blade sharpening $15.00, labor 45 minutes =$60.00 plus pick/delivery $75.00? Seems reasonable to me when you add tax. Looks like you should find a different place to have it serviced, Toro has no control over anything I see. Plus I googled that service kit number and found it immediately.
