The mechanism can be a pawl device associated with an overload coupling in the drive train that is actuated by a mechanical or electrical monitor to overload the device. The monitor can be a pivoted cover that partly overlies a rear roller or space adjacent same with projections that intercept the roller or a trip bar with contacts that opens or closes a circuit in a system that interrupts the drive to the moving parts responsive to contact with an external object. In another variation, the circuit can have sensors such as infrared or photoelectric cells to detect the presence or lack of presence of a human operator and these sensors can be placed in a tractor cab.

  • Patent number: 4321969
    Abstract: The specification discloses an improved garden tiller which, in addition to having power driven rotating tines on the front of the tiller transverse to the direction of travel, has a pair of free wheeling cultivator cylinders mounted to a stationary axle between the normal rear support wheels of the cultivator. The rear wheels can either be manually or power driven, and the forward motion of the machine turns the cylinders, on which radially extending vanes are mounted, to lift up the soil as they roll, and then release it, leaving little furrows in the soil which are good for planting and also keep the soil from drifting in the wind.

  • Patent number: 4279310
    Abstract: A soil working machine has at least one, preferably two rotors, one of which is at a higher working level than the other to achieve a relatively large working depth. The rotors are driven through a drive gear transmission located about midway along the length of the rotors. An adjustable coupling of the machine can be used to establish either one of two positions which are offset about an axis which extends transverse to the normal direction of travel. The transmission includes change speed gears in a first gear box for connection to a tractor p.t.o. and an output of the transmission is geared to a gear wheel housed in a flat gear box, the gear wheel being in driving engagement with pinions on the rotor shafts. The entire frame can be rotated to a limited extent relative to the transmission gear box owing to a flange connection between the two gear boxes and a setting device for their relative positions to one another.
