Going to add a ZTR to go with my Walker GHS. My JD/Walker dealer has a JD 757 demo with a mulch on demand 60" deck. I have it in my shop waiting for the ground to freeze so I can try it out in the wheat field behind my house. Anyway, has anybody heard about or tried this new mulch system. Apparenly JD only made 400 of these units. They are going to wait and see how they perform and to hear some feedback before building more. Incase you haven't seen one, their system works like this. It works similar to qwickchute's OCDC. When you flip the handle the OCDC covers the discharge opening and four baffles under the front of the deck flip down creating somewhat seperate chambers. I winched the front of the machine up and looked underneath. It looks pretty neat. You can go from side discharge to true mulching with the blades engaged. I tried it in my yard yesterday but my grass is so short it is hard to tell if it works well. Planning to run it on Monday, supposed to be 15 degrees that day. The wheat field is about 6 inches tall, should be a good test. I'll let everyone know how it does.
