Sulky apparatus including an operator standing platform, a tire and associated wheel rim for allowing the operator standing platform to move along the ground, a wheel well associated with the operator standing platform for housing the wheel rim and tire in an operational position, a tire axle having two end portions located in the center of the wheel rim, the two end portions being configured to rest in the bottoms of depressions located in the walls of the wheel well, a pivoting U-shaped axle locking member located at the top of the wheel well where the locking member can engage the upper surfaces of the end portions of the axle and secure the axle and the associated tire in the operational position in the wheel well, a pivotal cover covering the wheel well for allowing access to the wheel well and locking means associated with the wheel well and the cover for locking the pivoting U-shaped axle locking member and the cover in place in their operational positions. When the locking means is unlocked, it permits the pivotal wheel cover to be pivoted upward and forward and the pivoting U-shaped axle locking member to also be pivoted upward and forward and this allows the tire and the associated wheel rim to be removed from the wheel well.
