PROBLEM TO BE SOLVED: To provide a management implement capable of extracting a plurality of posts continuously by continuing the retraction of a running airframe, and performing the extractions of the posts by continuing the continuous retractions of the running airframe so that the extractions can be improved.SOLUTION: An apex carrier lever 17e capable of carrying the apex inner surface of a post W is formed in such a rising inclination as gradually rises forward from the back of a running airframe 1. In accordance with the continuation of the retractions of the running airframe, an apex carrier lever contacts in a rising inclination with the apex inner surface of the post rising on a farm field M, so that it can be gradually extracted from the farm field by the apex carrier lever.SELECTED DRAWING: Figure 2【課題】走行機体の後退動作の継続により複数本の支柱を連続的に引き抜くことができ、支柱の引抜作業を走行機体の連続的な後退動作の継続により行うことができ、引抜作業性を向上することができる。【解決手段】支柱Ｗの頂部内面を担持可能な頂部担持杆１７ｅを走行機体１の後方から前方に向かって次第に登り上がる登り傾斜状に形成し、走行機体の後退動作の継続に伴って頂部担持杆が圃場Ｍに立設する支柱の頂部内面に登り傾斜状に接触して頂部担持杆により支柱を圃場から徐々に引き抜き可能に形成してなる。【選択図】図２
