A quick note about "Partial Service":

From time to time, we receive a request for service of a lawnmower where the customer only wants the oil changed and the blade(s) sharpened. 
If you want us to only do the "bare minimum"--that's fine, but we would like to take this opportunity to remind you to make sure someone knowledgeable is doing the rest of the recommended work, so your equipment can continue to be reliable for you for many years to come.
