I have a John Deere Commercial F687 Z-Trak with Material Collection System for sale. Has 54" 7 Iron Mowing Deck 23 Horse Kohler Only 185 Hours 9 Bushel Material Collection System I am the second owner. I bought it from a friend that retired from landscaping and sold out his equipment. I bought it thinking my son could possible use it for his landscaping business but he decided to keep his Scag. I bought it last fall and used it to collect leaves. It works like a dream, you can dump without leaving the seat. I paid $7500 for it last fall and will sell it for $7200. It was bought and has been serviced exclusively at Sloan Implement (a large John Deere dealer in central Illinois). Current price for this set-up is about $10,000. If interested please call Dave at 217-756-8299 or cell 217-521-0814. Thanks for looking. Dave (Shooter) P.S. The picture doesn't show the chute or blower assembly but that is included and is in excellent condition.
