I have been at some trade shows over the past few years and have seen the Ride-on spreaders that use a small boom sprayer in fropnt and spread a granular fertilizer. I'm not talking about the Turf trackers but the actual ride-on (sulky-like) spreaders that have a small 5-6 hp engine underneath. Has anyone had any experience with them and how well they work? Interested in knowing the problems operators ahve experienced with them. Are you actually able to get more work done or is it just a matter of less fatigue on the applicators? Would appreciate any input that someone may have. Thanks!
