Imagine an aircraft that has set the ag industry standard for tough dependability and you’ve got the Thrush 550P. It offers you a 29,000-hour wing spar life and a 550-gallon clear-view hopper. No wonder this aircraft is renowned for its solidly rugged construction and revered for its simplified systems and worry-free maintenance. Now add the fact that its wide-stance spring landing gear is capable of absorbing 8,800 pounds on short, rough strips and its optional spring steel landing gear can be added to increase weight for take offs and landings, and you can pretty much check off whatever’s on your “to do” list.
