A gauge wheel (1) for use in controlling the depth of a furrow formed by a planting member of cultivation equipment includes a hub member (5) having a central hub and an outer peripheral portion (9)； and a resilient coil member (3). The resilient coil member (3) includes a plurality of coil windings (17) extending closely adjacent to the outer peripheral portion (9) and defining an outer periphery of the gauge wheel (1). The coil member (3) is connected at or adjacent one end to the hub member (5). In use, the resilient coil member engages the soil on a side of the furrow and controls the depth by which the planting member cuts into the soil to form the furrow. There is also provided a coulter gauge wheel which includes a coulter disc and at least one gauge wheel as described above.
