Who has used the Mulch On Demand System??? I think it is a great concept, but wonder about the long term use under commercial conditions, such as curb hopping, dips and valleys. Will it tear up the linkage? The one thing I like about this is the obvious mulching ability for leaves, etc. I also demo'd the JD 757 and was happy with the handling. It held the side of a hill much better than my Gravely 260Z. In addition, I am seeing JD make a commercial push in the Central Indiana area. There are a lot more LCO's running around with "Green" on their trailers. As always, JD wants my business for y/e pricing, but I want the professional's opinons regarding the in-the-field usage. Thanks for your responses.
