PROBLEM TO BE SOLVED: To provide a fertilizer for a tractor, having good balance of the center of gravity, and facilitating the insertion of a fertilizer.SOLUTION: The fertilizer for the tractor includes a pair of fertilizing tanks (10) on the right and left which are constituted to be independently moved from rear positions of a car body (1) to both sides of the car body (1) per each of the fertilizing tanks (10) on one side by supporting and moving mechanisms (T). Position-changing mechanisms (R) of the fertilizing tanks (10) enabling the installed height positions of the fertilizing tanks (10) moved from the rear positions to the side positions of the car body (1) to be moved to fertilizer-inserting positions at the lower levels of the side positions are also installed.COPYRIGHT: (C)2013,JPO&INPIT【課題】重心のバランスが良く、肥料投入のし易いトラクタ用の施肥機にする。【解決手段】肥料タンク(10)を左右一対備え、左右の肥料タンク(10)は車体(1)の後方位置から車体(1)の両側方に片方の肥料タンク(10)ずつそれぞれ独立して支持移動機構(T)で移動可能に構成した。また、車体(1)の後方位置から側方位置に移動した肥料タンク(10)の設置高さ位置を、側方位置より低位の肥料投入位置に移動可能とする肥料タンク位置変更機構(R)を設けた。【選択図】 図11
