Abstract: A stationary spreader (10) which is activated in response to a signal from a sensor (118) indicating a condition of the adjacent ground surface, is described. The stationary spreader includes a bin (12), a spreader housing (34) and a control box (106) which are removably mounted together. The bin holds the material to be spread and preferably has a stirrer (16) and an auger (18) which both act to move the material out of a dispensing opening (24) in the side (12D) of the bin. The spreader housing is mounted over the dispensing opening and includes a spreader assembly (38). The spreader assembly has a lifting motor (40), a pair of solenoids (62) and a spreader bucket (44). The lifting motor is mounted above and connected to the spreader bucket and acts along with the solenoids to vertically raise or lower the bucket. A spreader compartment (76) is located in the bottom of the bucket and houses the spreaders (86 and 88).
