Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a height adjustment balancing device for a lawn mower. Background Art

[0002] The lawn mower is mainly used for repairing duckweed. According to different terrains, the height of the mower's cutting blade needs to be adjusted. At the same time, it can also be adjusted adaptively according to the length requirements of the grass. The traditional way is through the limiter, which often has only a few gears, and they are fixed gears. The adaptability to the height is not very strong. It is an equidistant height change, which requires the user to handle it with manpower, so the adaptability is not strong. The existing automatic adjustment device in the electric control aspect is already quite popular, and this part is also relatively simple.

However, the more complex the machine structure is, the higher the error rate and failure rate. Therefore, a height adjustment and balancing device for the lawn mower is needed to adjust the height of the lawn mower more simply and effectively, and ensure the balance of the lawn mower during the adjustment process.
