摘要：
To provide a work machine capable of accurately controlling a ground height of a second ground work machine.SOLUTION: A work machine includes: a travelling body that travels in a farm field； a first ground work machine mounted on the rear part of the travelling body； a second ground work machine having a machine frame mounted on the rear part of the first ground work machine so as to be lifted and lowered, a planting device that is supported by the machine frame so as to be lifted and lowered and enters the farm field and plants seedlings when lowered, a soil covering wheel that rolls on the farm field for covering the seedlings planted by the planting device with soil, and a height detection mechanism for detecting a ground height of the machine frame； and a control device for executing machine frame lifting and lowering control for the first ground work machine on the basis of a result of the detection by the height detection mechanism so that the ground height of the machine frame becomes a preset ground height.SELECTED DRAWING: Figure 1【課題】第２対地作業機の対地高さの制御を精度よく行える作業機を提供する。【解決手段】作業機は、圃場を走行する走行体と、走行体の後部に装着された第１対地作業機と、第１対地作業機の後部に昇降可能に装着された機枠と、機枠に昇降可能に支持され且つ下降する際に圃場に突入して苗を植え付ける植付具と、圃場を転動して植付具で植え付けられた苗を覆土する覆土輪と、機枠の対地高さを検出する高さ検出機構とを有する第２対地作業機と、機枠の対地高さが予め設定した設定対地高さになるように、高さ検出機構の検出結果に基づいて第１対地作業機に対して機枠を昇降制御する制御装置と、を備えている。【選択図】図１
