I am looking for a new ride-on spray machine for the spring. I would appreciate any advice on what works and what doesn't. I currently have a GT Promax made in Florida. It has some great features, zero turn, dual drive tires on each side, it holds 65 gallons of liquid, 4 bags of fert, plus whats in the spreader, and has front mounted booms about 8 inches above the ground. All this is great except the machine wasn't made to haul all of the weight, the hydros went after 2 years. The wheel bearings on the drive wheels burn up every year (they are in an oil bath), the axle snapped in half on one of the drive tires earlier in the year, as well as many other problems. I consistently put $ 2,000.00 into it a year. After paying $ 17,000 for the unit originally I am disappointed in it. It sits on a modified Walker frame. What about the Perma Green Supreme Model? Any ideas would be appreciated. I need the unit for lawns 1 acre to 40 acres of turf sites and it must have the capabillity of both liquid and dry applications simultaneously.
