The present invention relates to cutting tools, in particular, to control systems for cutters such as vegetation cutters, especially hedge cutters or trimmers (10). Hedge cutters (10) frequently suffer in use from a problem of blocked cutting blades when they encounter a twig or branch whose size or density exceeds the capacity of the blades. We describe a vegetation cutting apparatus (10) having a plurality of cutting blades (11,12), at least one of which blades (11,12) is drivable by an electric motor. At least one driven blade (11,12) is movable between two predefined points of maximum travel. The apparatus (10) includes a control mechanism which causes a change of direction in the movement of the at least one movable blade at a point intermediate the points of maximum travel in response to an event sensed by the control mechanism.

This innovation provides a hedge shear extendable handle enhanced structure focusing on resolving the operating inconvenience and physical deficiencies such as bending and deformation resulting from the operations of legendary hedge shear. The main structure of the enhancement is a pivot joint formation of an inner and outer tube. The main feature is the H-shape profile structure of the inner tube with a slide way built with an internal diffusion slot and a perforation slot. The perforation slot has a few interleaved positioning fillisters along the slide way. The positioning fillisters in the inner tube will park the sliding block when it shifted upward and matching with the locating block on the top pillar while moving upward. A press button assembles on top of the pillar and remains in an upward position with the sliding block under normal condition with the help of a spring. The main functionality is retaining the convenience of the press button operation while maintaining ruggedness and endurance of the product using such technique.

An improved brush cutter having an upper feed control member with stop, forward, neutral, and reverse positions also has a lower feed stop member with selectable sensitivity. Another aspect of the invention is to predict the feed roller shutoff point according to the rate of engine deceleration. According to another aspect, when the feed rollers stop feeding material into the cutters, to overcome drag on the cutters, a controller stops the feed rollers and then reverses them for a short time, and then reverses the rollers again if the problem is still present. To prevent jamming, a pressure switch senses when oil in a hydraulic motor system for rotating the feed rollers is too high and the controller momentarily reverses the feed rollers and then causes them to go forward, a cycle which can occur several times until the feed rollers are no longer stalled. By another aspect of the invention, the controller senses characteristics of the brush cutter and chooses an operating system based on the characteristics sensed. The controller can also sense if the brush chipper has not been used for a predetermined period of time and automatically reduce the idle speed of the engine until the brush chipper is used again, and then automatically return the engine to a normal idle speed before the feed rollers will pull brush into the brush chipper.
