Even when the turf is dry, our PG units tear up the turf when we make turns if the hopper is not full. We plan to buy one or two Z-Spray units at the end of this year cuz our PG's have seen their best days, but I'm wondering if the Z-Spray units have the same problems tearing up the turf??. Seems weight distribution is the key? We will "unhappily" be hauling a trailer just so we can transport the Z-Spray. PG units are front-wheel drive, while the Z-Spray units are rear-wheel drive (where the operator stands). I spread granular Sevin insecticide (lightweight) to several lawns recently, and everytime I turned the PG Ultra, it tore up turf. Seems the PG units are reliant upon weight in the hopper for proper taction? rscvp Thanks much for any feedback.
