In the forward rotation, the wheel of the agricultural machine drives the moving gear 46 to rotate in the reverse direction by the reverse rotation of the intermediate shaft 4, and the moving gear 46 drives the output shaft 8 that meshes with it to rotate in the opposite direction, and the output shaft 8 The wheel mechanism can be reversed and the operating handle of the agricultural machine can be turned so that the tool is in front and the wheel is behind, which can be used for loosening; and when the toggle lever 7 moves the moving gear 62 on the first shaft 6 to When the third right position of the tool mechanism (as shown in the seventh figure) L, the shifting gear tooth system and the second transmission gear of the manual shaft 3 are mutated with the third transmission gear 33, and the first shaft 6 The upper clutch gear 61 is disengaged from the recess 620 of the moving gear 62. When the input shaft 3 is rotated by the external force, the intermediate shaft 4 is caused to drive. The first shaft 6 is stopped by the clutch gear 61. In the recessed to (4), when the moving gear 62 is driven, only the first shaft 6 will be rotated. The first shaft 6 will not rotate, and the cutter mechanism will stop running in the third gear position. The mechanical wheel is rotated by the intermediate shaft 4 疋 π moving gear 46, and the moving gear 46 is Move the output shaft ^ turn two financial resources _ can drive the wheel mechanism forward, so that the agricultural machinery ^ into the 're-sentence' # toggle rod 7 push the moving gear 62 on the paste - two wide: the fourth slot When the position (as shown in the eighth figure), its movement: two: the second transmission gear 33 and the fourth transmission gear 3 of the input shaft 3, the positioning of the moving tooth tilting card on the top of the 200817606 system card is set in the clutch The slot 631 in the recess 63 of the seat 63 allows the moving gear 62 to be positioned and engaged with the clutch seat 63. When the input shaft 3 is rotated by an external force, the third transmission gear 33 and the fourth transmission gear on the input shaft 3 are engaged. 34, the moving gear 62 meshing with it is reversely rotated, and the moving gear 62 drives the clutch seat 63 that is engaged with each other to rotate together, and the first shaft 6 rotates accordingly, and drives the transmission gear 6 to rotate. Recording coffee _ is set in Naru's driven tooth, 27 is reverse rotation 'The tool mechanism is reversed in the age of the cutter, and the wheel of the Chenye machine is driven by the rotation of the towel 4 to rotate the moving gear 46. The reducer 46 has a positive rotation of the shaft 8 and the output shaft 8 can drive the wheel mechanism to rotate forward 'to enable the agricultural machinery to Thus, by setting the width of the clutch gear 61 and the depth of the recess (4) of the shaft record 62, when the blade is moved to move to the second slot position, the clutch gear 61 can still be held in the recess of the mobile record 62.筵 _, 第二 龄 第二 second position ^ is sustainable 'and the wheel is light and reverse, the agricultural machine's operating handle is turned, you can carry out the loose soil system, for the operator to make it more convenient: The present invention has indeed achieved the intended use and function: the object is ideal and practical, and the application for the patent application is interesting and meticulous.
