(under subclass 452) Apparatus in which the actuator comprises a motor which is in motion just long enough to effect the desired movement of the earth working element and then stops.
(1) Note. Servomotor actuators are very common in this art and only unusual types should be cross-referenced to this subclass. The search notes below list subclasses in which "servomotor" appears in the title.

2+, for an implement with an automatic control for a servomotor.
294, for devices having a series of elements, such as wheels or tools, which are sequentially operated by a power cycle where the power is supplied by sequentially operated servomotors.
316, for servomotor actuator on a trailing implement controlled from a leading vehicle. 413, for wheels vertically adjusted by a servomotor actuator.
464, for a servomotor actuator forcing a tool down.
465, for a servomotor with a follow up control for lifting a tool for transport.
466, for a servomotor for lifting a tool for transport and means for holding the tool raised to relieve the load on the servomotor.
831, for plural servomotor actuators for lifting an elongated earth working blade positioned ahead of a motor vehicle.
