I received a letter in the mail today from Exmark with a plastic card that looks like a credit card. It has the model number, serial number, date purchased, and name of dealer along with all the part numbers for belts, filters, and hydro oil. I like this a lot because now when I go to my dealer all I have to do is pull out my wallet and show the card with the part number I need instead of standing there waiting while they search in their computer for the part number. Its not a big deal but it is convenient. This must be a new thing for the Next Lazer because this is my fifth Exmark and first time I've received anything like this. I am continually impressed with my latest purchase and can't help but smile every time I operate it.
