Abstract: A drive arrangement for a hand-guided working machine for agriculture, forestry and horticulture applications. The drive arrangement comprises an electric motor, a DC power source for electrical energy, and a control apparatus for the electric motor which is fed from the DC power source. The electric motor has a specific, in particular linear, characteristic curve between the electric current which is consumed by the electric motor and the rotational speed of an output shaft of the electric motor. The control apparatus has current-limiter which limits the current which flows through the electric motor to a maximum value in order to protect the electric motor against overloading. The control apparatus limits the current consumption of the electric motor in a range of low rotational speeds to values which are considerably smaller than the characteristic curve values which are given for these rotational speeds by the characteristic curve of the electric motor, as a function of the rotational speed.

Abstract: A hedging apparatus is disclosed which comprises a wheeled vehicle having a specially adapted chain saw thereon for cutting limbs and branches from trees, hedges, or shrubs, which are planted in rows. The chain saw is provided with a plurality of spaced-apart guide bars which extend forwardly of the cutter chain, thus assuring the severing of limber branches which would otherwise be pushed aside by the saw and remain uncut. Resilient springs in the form of elongated rods can be used in conjunction with the guide bars to prevent chattering of the branches being cut. To particular advantage, a positioner can be provided for setting the chain saw blade at a selected pitch angle and for maintaining the selected pitch angle during a hedging operation. To further advantage, a hopper can also be provided for collection and disposal of the severed limbs and branches during the hedging operation so that they do not have to be subsequently gathered up and hauled to another site for disposal.

Abstract: An apparatus for trimming trees, hedges, and the like including a cutting arm supported in a centilevered fashion from an upstanding tower. The cutting arm includes flexible, resilient, drive and idler wheels rotatably mounting a continuous, band-type saw blade. As the blade is rotated in a closed path, it cuts and transports the trimmings toward a guard on the arm which causes them to be deposited in a row adjacent the path of travel of the apparatus. Means are included for moving the cutting arm vertically along the tower and for pivoting and rotating the arm in order to selectively position the height and angle of the cutting blade.
