A triangular or rectangular drag brush is a grooming tool with stiff, synthetic bristles, typically towed behind a utility vehicle or small tractor. It is designed to level infill, lift flattened turf fibres and prevent directional pile lean. Regular brushing improves performance consistency and extends the life of the turf by maintaining fibres upright. It also helps to evenly redistribute infill, reducing wear in high-use zones.
