We have two of these units. They spread & spray an effective pattern of over TEN feet at 5 mph. Available pounds of dry fert per day = more than 4 TONS. Available gallons of herbicide = more than 1200 GALLONS. I'm talkin' just one pickup truck w/a ride-on sprayer-spreader unit (with the aid of our others trucks in the area). No trailer to pull. No large truck either. Plus this ride-on can treat small 2000 s/f lawns or 20 acre properties whenever it's needed in the "same day in the same route". Just thought I would provide this info in case anybody is curious or thinking about comparing stuff. If anyone wants to see pics, rscvp. Thanks.
