PROBLEM TO BE SOLVED: To provide a working implement controller of a tractor capable of effectively using a draft raising function.
SOLUTION: The traction load for raising a working implement can be set by adjusting the position of a pushing member relative to an abutting part by swinging a spool operating lever for a daft with one end side as a fulcrum. A draft feedback rod is pushed by a set traction load or larger than a set traction load to swing the draft spool operating lever with the other end side as a fulcrum and the abutting part is pushed by the pushing member to operate a spool so that the working implement is raised. When a lift arm is swung upward to the vicinity of the highest raised position when the working implement is raised by a draft operating means, the draft spool operating lever is swung with the other end side as a fulcrum by a rising restraining link in such a direction that the pushing member is separated from the abutting part and the draft feedback rod is contracted to permit the swing, so that the rising motion of the lift arm is stopped.
