Shovel

A shovel, comprising:

• a lower traveling body;
• an upper turning body pivotally mounted on the lower traveling body;
• a drive source mounted on the upper turning body;
• a first hydraulic pump driven by the drive source and mounted on the upper turning body;
• a second hydraulic pump driven by the drive source and mounted on the upper turning body,
• a first bleed valve disposed in a first conduit into which the first hydraulic pump discharges hydraulic oil;
• a second bleed valve disposed in a second conduit into which the second hydraulic pump discharges hydraulic oil;
• a plurality of hydraulic actuators respectively corresponding to a boom, an arm, and a bucket, and driven by the hydraulic oil discharged from at least one of the first hydraulic pump and the second hydraulic pump;
• a plurality of operating devices corresponding to the boom, the arm, and the bucket, for operating the plurality of hydraulic actuators;
• and
• a control device configured to control a plurality of acceleration/deceleration characteristics of the hydraulic actuators in response to the operations of the operating devices depending on work modes and amounts of respective operations of the plurality of operating devices,
• wherein the control device controls the acceleration/deceleration characteristics by changing opening areas of the first bleed valve and the second bleed valve and a setting condition of the drive source, depending on the work modes and amounts of respective operations of at least one of the plurality of operating devices.
