TurfSavr self-propelled tool cuts and seeds in a single, 22-in.-wide pass. Doubles as a dethatcher—just add optional flail reel and remove seed box. Onboard knives, made of carbon steel, are tightly spaced to improve seed germination. Knives adjust to various heights for conquering specific turf conditions, plus retract for transport and storage. Select from two engines, each with three forward operating speeds, plus reverse and neutral gears. SourceOne, Lincoln, Neb.
