PIN Number decode

At work we have a Turf Gator that we're trying to find the manual for as there are some things we're trying to figure out about it. Could someone decode the PIN number?

W00TURF019965

Here is a picture of the label under the passenger seat, as you can see there is also no serial number given. There are no other labels on it.

Thanks.
