I have a 2003 Hustler 60" Super Z mower (15 mph) that includes the BacVac collection system. The vac runs off of the deck, so there is no extra engine to deal with like a Trac Vac. This unit can be dumped from the seat, so there is no need to get off the mower and remove a can or bags. The mower has a 25 hp Kawasaki engine which has less than 100 hours (dealer replaced $2200) Machine has around 1500 hours. It has had all wheel motors and pumps replaced in the past 2 years. We used this machine for clean ups only and not for weekly cutting. Mower has suspension seat and flex forks for a smooth ride. This is a nice cutting machine that does a nice job with leaves too. $4500 John 586-634-2904 All repairs have been done at the Hustler dealer since I bought this machine in 2004. Everything that could wear out has been replaced. It won't let me post the good pix of this machine because I have them elsewhere on this site. I will try to get some new ones this week.
