Tree and/or brush clearing and/or trimming equipment mounted on a tractor includes a rotary cutter provided with blades pivotally mounted on a rotating shaft and enclosed in a cutter housing open towards the plants to be cut. The cutter is mounted at the end of a multi-section arm, which arm is mounted on the tractor by a joint permitting both angular and rotational disposition of the cutter and the cutter housing, permitting both clearing of undergrowth around the tractor and cutting of low-growing branches or the like.

A surveying and mapping implement indicates the level differences of the ground over which it travels, in relation to the distance travelled. It comprises a carriage consisting of a swivelling front wheel, two center wheels attached to the outside of a U-shaped vertical frame, and two rear wheels connected to the U-shaped frame by means of a thill and a universal joint positioned co-extensive with the axis of the center wheels. The universal joint permits the rear wheels to move up and down and sideways, as well as to twist in relation to the center wheels. The wheel base between the center wheels and the front wheel is identical with that between the center wheels and the rear wheels, in order to facilitate calculations. Recording instruments are provided on the carriage adapted to measure the distance travelled, the different angles of inclination and of angular twist of the rear wheels in relation to the center wheels, and to transmit their output to computer means adapted to record the surface features of the ground.

Ground clearing apparatus (10) and a method for transporting the apparatus are provided. The ground clearing apparatus (10) includes a plurality of ground clearing tools (20) attached to a rotating shaft (18). The ground clearing tools include a chain (22) having a plurality of links and a hammer (24) attached to one end of the chain (22). The rotation of the shaft (18) causes the hammer (24) to strike objects in its path and generally mill the ground surface.

A device for attachment to an uprooting implement is designed for compacting plant residue into cylindrical or rope-like shape and to cut the compacted cylinder into short wafers. The device comprises four rollers in parallel alignment symmetrically positioned around a central space defining the compacted cylinder, and urged toward the central space by springs. The rollers are positioned with their axes in the direction of travel of the uprooting implement and all are rotated in the same sense of rotation. Each roller has a cylindrical rear portion and a frusto-conical front portion provided with a broadthreaded screw, the screws serving to press the plant residue into the space between the cylindrical roller portions. Conveyor means are provided for feeding the plants into the compacting device, and cutting means are provided to the rear of the rollers.

A method of drying waste in a continuous process comprising feeding waste into a waste receiving means, continually moving said waste from said waste receiving means to a waste discharge means. The waste is heated and aerated as it is moved from said receiving means to said discharge means. Said feed wet waste is substantially dry when it is at said waste discharge means. A continuous waste drying system comprising: accepting and feeding means for wet waste; continuous-flow conveying system for the waste; aerating and drying means for the waste; heating means of the drying air and the waste, and sensing and control system for optimum drying operation.

A travelling rolling digger (1) for sequential hole drilling or for producing sequential cultivated spots in soil. The travelling rolling digger (1) includes at least one drilling shaft which is rotatable by a drive mechanism about a longitudinal shaft axis and has a rotating soil penetrating edge. The drilling shaft is mounted to roll about a horizontal shaft in a soil penetrating plane while the horizontal shaft moves in a direction of travel of the traveling rolling digger. The rotating drilling shaft enters the soil at an entry angle and digs into the soil while the horizontal shaft moves in the direction of travel and the drilling shaft continuously changes its angle relative to the soil from the entry angle to a vertical position. The traveling rolling digger further comprising at least one cleaning blade (6).

The object of the invention is to provide a method and an apparatus for detecting obstacles on railways and stopping the train to prevent collision with the obstacle. The detecting device in or on the train is following the rails and detecting any obstacle on the rails. The image of the rails with obstacle is sent to a computer, analyzed, directing the detecting device to the rails and sending the images to a monitor and alarm the driver by an alarming system to actuate the brakes and stop the train before hitting the obstacle. The computer may also actuate the brakes automatically and stop the train before hitting the obstacle.
