Gravely 260 2006 versus 2007

[acreage to mow]

Need feedback from anyone knows issues regarding Gravely 2006 versus 2007 year models (2006 260 Diesel #992121) vs. (2007 260 Diesel #992156). Found a 2006 demo with 50 hours and wonder how that should affect bid I would propose to a dealer.

Any other issues good or bad, one year versus the other?

Thanks!!!
