An automated batting tee apparatus includes a housing having a top opening, a ball dispensing mechanism for feeding balls one at a time to above the top opening, a ball holder tube forming a batting tee disposed upright in the housing and aligned with the top opening thereof and having an upper end portion for receiving a ball and a lower end portion spaced below the upper end portion, and a drive mechanism arranged upright in the housing externally of and alongside the ball holder tube for vertically moving the ball holder tube and actuating the ball dispensing mechanism. The housing includes a base that rest on the ground and an enclosure having an inner shell on the base and an outer shell slidably mounted over the inner shell and adjustable to different vertical positions relative to the inner shell to adjust the height of the upper end portion of the ball holder tube above the ground. The drive mechanism includes a pair of spaced upper and lower pulleys rotatably mounted to a frame supported by the outer shell within the inner shell and a flexible endless drive belt extending over and between the pulleys and movable therewith. An actuating linkage intercouples the ball dispensing mechanism to the endless drive belt so as to move the ball dispensing mechanism between a ball blocking position and a ball releasing position as the ball holder tube is moved by the endless drive belt between a lowered ball receiving position and a raised ball hitting position.
