We are the first to admit that a tractor is not exactly a traditional wedding vehicle.  They can however work well in the right setting for static display; photographs or to help your guests find the venue.
 
Impossible to miss, obscure or blow over, the tractor makes the clearest possible statement to your guests that they are in the right place. You could also say in your wedding invitation to look for the tractor, and even include a picture if you wish.

We have a classic 1950's Grey Ferguson T20 tractor available.
