I've heard the best are the Ultra's vs the new Magnums. I'm wondering why. Personally, I don't think the PG units come out of the factory with proper spray coverage. I have test-driven both....,same o same o (spit coverage). Since we installed a 3.0 gpm pump w/a motorcycle battery, our weed control problems were quickly solved. Now our mowing subcontractor wants one like ours (modified version of an Ultra). Bottom, line: What is your favorite ride-on sprayer?
