Description

one

This invention relates to small-sized motorized mowers, operated by a number of workers in progress and intended primarily for work in mountainous areas.

Known small-sized motorized mowers, including the engine, mounted on the gearbox housing with a vertical eccentric drive shaft of the cutting unit. The engine in the well-known mower is located on the side of the wheel opposite to the attachment of the cutting unit. However, during operation of such mowers, a tilting moment occurs on the slopes, to balance which it is necessary to apply force to the mower control knobs in the direction opposite to the tilting moment. At the same time, the cutting apparatus does not have a stable cutting height, which significantly complicates its operation.

In the proposed mower, in order to facilitate its operation when working on mountain slopes, the gearbox housing is made with a receiving part rotating around the eccentric shaft for mounting the engine in different working positions relative to the cutting unit.

The receiving part of the gearbox is provided with a locking pin, which fits into one of the holes on the radially stationary part of the housing.

Pa drawing shows the proposed kosnka in the section.

The mower consists of a running wheel /, an internal combustion engine of the “Friendship 2” type, mounted on the gearbox housing 3

vertical eccentric shaft 4, frame 5, bushings 6, onornoh bearings 7, 8 and 9 n segmented cutting unit 10. The housing 3 of the gearbox is made with a turning part around the eccentric shaft 4 //

for installation of the engine in different working positions relative to the cutting apparatus. The receiving part of the gearbox is provided with a locking pin 12 which fits into one of the holes on the radially located fixed part of the housing.

Before starting work, depending on the size of the slope and the direction of movement of the mower, the motor 2 turns around the eccentric 1tric shaft 4 and is set as a balancer in a position that will compensate for the tipping force acting on the frame control handle 5. with the help of the pin 12.
