I have a pretty good operation going with just a 36'' Belt Driven WB, trim mower, trimmer, etc. I was thinking about upgrading to a dual hydro with a sulky to increase my productivity. It seems like most dual hyrdro's are in the $5000s. The BOP's range from $3100 to $3500, the Hustler TrimStar is around $4000, and the the 36'' Wright Stander is around $4600. Are there any other Dual Hydro's priced under $5000?
