Abstract
PURPOSE:To make the operation of a front loader easier by a method in which couplers are provided for the operating levers of control valves for boom and bucket, and coupler tools to connect detachably with the couplers when the levers are in a downward scooping position are provided. CONSTITUTION:When a bucket 11 is in a damped state, the first rocking element 27 is rocked to pull up the spool 17 of a boom control valve 15 when an operating lever 14 is operated toward the lowering direction. The boom cylinder is contracted and the boom 8 goes downwards. At the same time, when the lever 14 is operated toward a scooping direction, the second rocking element 28 is rocked to push down the spool 18 of a bucket control valve 16 and the bucket cylinder is contracted to put the bucket into scooping action. When the scooping action is started, the coupler 39 of the lever 14 is engaged with the coupling body 44 of coupler tool pivotally supported by a control box 23, and the lever 14 is locked at the scooping position.
