Harness racing use a standing start. The sulky (informally known as a "bike") is a light, two-wheeled cart equipped with bicycle wheels. The driver (not a "jockey", as in thoroughbred racing) carries a light whip chiefly used to signal the horse by tapping and to make noise by striking the sulky shaft. There are strict rules as to how and how much the whip may be used; in some jurisdictions (like Norway), whips are forbidden. For exercising or training, the drivers use what is known as a "jog cart," which is a sulky that is heavier and bulkier than a racing unit.
Mop bucket cart Mop bucket cart A mop bucket cart (or mop trolley) is a wheeled bucket that allows its user to wring out a wet mop without getting the hands dirty. The cart has two buckets with the upper one usually clipped onto the lower. The upper bucket is used to place the wet mop for storage and press handle to wring out the mop. Water trickles down to another bucket below, which collects the waste water. In some carts, there are separate lower front bucket to collect waste water. The smaller lower rear bucket is filled with a floor cleaning solution.
