Got a great idea for a little off-season money maker. This will only apply to customers who we TREAT, but do not maintain the lawns. My end of the year letter includes: Late fall is a great time to get your lawn mowers winterized and ready to go in the spring. Let us do it for you. We will #1 drain the tank and carbuerater, #2 change the oil #3 replace the spark plug, and #4 sharpen the blade. We will even pick up the mower and bring it back to you! (some of you may want to exclude tractors) You will be notified if any mechanical repairs are needed. I just sent out the letters and got one right away.
