Does the unit have a suspension for uneven terrain?
The RS-500 has a pivoting frame that turns on a center line axis. The front wheels can rotate separately from the rear wheels. The wheels are 11 x 4 turf and 16 x 7.50-8 turf. The current design has the paint shoe and nozzle assembly located directly below the operator of the unit, thus minimizing the effect of rough terrain versus those units lining from the side of the self propelled unit.
