ztr lawn mower blade height adjustment device

Abstract

The invention discloses a cutter height adjusting device for a ZTR (zero turning radius) mower. The cutter height adjusting device comprises a frame and a cutter, and is characterized by also comprising a boosting mechanism, an adjusting and controlling mechanism and a transmission mechanism; and the height of the cutter is adjustable relative to planes, which are in contact with grassland, of wheels in the vertical direction. The height of the cutter of the zero turning radius riding type mower can be adjusted through pedal plates; an adjusting range exceeds the 1 / 3 radius of a tire; when the height of the cutter is increased, the trafficability characteristic of the whole mower is improved, so that pruning requirements of uneven grassland and high stalk weeds on the mower are met; and when the height of the cutter is reduced, pruning requirements on the early growth stage of lawns and grass of low and short lawns are met. The cutter height adjusting device has the advantages of convenience in operation and high work efficiency.

Description

technical field [0001] The invention belongs to the technical field of lawn mowers, and particularly relates to an adjusting device for adjusting the height of a ZTR lawn mower cutter head. Background technique [0002] With the development of economy and urban construction, major cities are competing to build theme parks, stadiums and golf courses. These places are basically equipped with large areas of lawn green space. The trimming of these lawn green spaces is an important part of later management. Mechanized operations can not only improve production efficiency and reduce overhead, but also improve the quality of lawn mowing. Compared with ordinary tractor-type lawn mowers, Zero Turn Radius (ZTR) riding lawn mowers can enter areas that are difficult to reach due to the use of forward and reverse driving wheels to realize the in-situ steering function of the lawn mower. Mowing operation is less affected by the limitation of narrow space, expands the operating range, has...

AI Technical Summary

Problems solved by technology

[0004] To sum up, there are some deficiencies in this cutter head height adjustment device: one is that manual adjustment requires high physical strength because the cutter head weighs tens of kilograms, and it is difficult to adjust it especially for weak workers; The grass mower must stop running. After the wheels stop, the brakes are used to pull the adjustment lever with one hand, and insert the inline limit pin with the other hand. It cannot be adjusted during the working dynamics, which will affect the work efficiency; the third is that there is only 16 different limit holes, corresponding to only 16 working cutter head heights, which cannot be adjusted at any height
