Abstract
An applicator includes a spinner rotated by the parking brake output shaft of a hydrostatic transaxle driving first and second drive wheels. Material delivered from a hopper on the spinner is spread by the spinner rotating at a speed corresponding to the rotating speed of the drive wheels. Liquid is sprayed by either a trim nozzle intermediate sides of the frame or broadcast nozzles adjacent the sides of the frame. A spray lever is pivoted to slide a slide linkage from an upper position to a lower position abutting with a biased actuator of an on/off valve, with the spray lever and a spinner gate opening lever operable at the same time with just one hand. During transport, a front bumper is received in a horizontal leg of an L-shaped slot and a cutout in an arm pivotably mounted to a stop in which the L-shaped slot is located and in a locking position. A locking pin is inserted through apertures in the arm and the stop in the locking position.
