The following is offered by John Deere.... Deferred Warranty For eligible equipment purchased between November 15, 2004 and February 28, 2005 warranty will not start until March 1, 2005. Includes Quik-Trak Mowers and Z-Trak Mowers. Now, I've always though this is something MFG's should do anyways for those of us that don't mind making the off season purchases, when dealers could really use the business. It's a good time to get familiar with a new piece of equipment and a great purchase for that last minute tax break.
