As a substitute to using herbicides, the Red Dragon Backpack Flame Weeder is designed primarily for stale (pre-emerge) plant bed, between-row, and spot weed control. Weighing approximately 221/2 pounds empty and 34 pounds full of propane, the product's components include: a 33-inch-long, 400,000 BTU torch and 5-foot hose; aluminum backpack frame with padded shoulder, back, and hip straps; and 3-gallon propane cylinder. Its flame-control squeeze valve allows adjustment from a small, low-heat flame up to a 2,050-degree torch and maintains just a pilot flame with the trigger is released.
