The GrandStand striping roller is compatible with both 2009 and 2010 models.
Studio and field photography of the final production configurations is not yet available. However, the photos included with this post (taken of earlier prototype machines) should give you a reasonable feel for the location of the roller on GrandStand models. The roller is spring-biased toward the turf, and can be disengaged by connecting it to the operator platform as shown in one of the photos.
Be aware that although the execution is essentially the same on small-frame (36" and 40") and large-frame (48", 52", and 60") models, there are two different kits for the two different frame sizes. 36"/40" -- kit #117-8560; 48"/52"/60" -- kit #114-3521.
