<p><P>PROBLEM TO BE SOLVED: To provide a PTO shaft driving structure for a tractor with a rear PTO shaft on the rear part of a body at the rear end of a transmission case, having a high degree of freedom in design by giving less constraints to various kinds of transmission members when arranged in a transmission system, particularly, in a PTO transmission system while allowing the on/off-operation of a grand PTO. <P>SOLUTION: The PTO shaft driving structure comprises a grand PTO lever 45 for selecting a "grand PTO on-operation" condition of transmitting shifting power through a travel shift mechanism to the rear PTO shaft 27 or a "grand PTO off-operation" condition of transmitting the power of the PTO transmission system arranged in parallel to the travel shift mechanism to the rear PTO shaft, and a PTO clutch lever 32. A mutual supervision means is arranged on the lateral outside of the transmission case for supervising and preventing the development of the conditions that the grand PTO lever 45 is at a position of "grand PYO on-operation" and the PTO clutch lever 32 is operated to a position of "clutch on-operation". <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
