Abstract

A working machine includes a travel device, a motive power transmission device configured to transmit a motive power to the travel device, a transmission case configured to house the motive power transmission device, and a hydraulic operation fluid tank disposed on an upper surface of the transmission case.

Claims

1. A working machine comprising:

an operator seat;

a first operation lever disposed to right of the operator seat;

a second operation lever disposed to left of the operator seat;

a first cover arranged below the operator seat;

a hinge disposed on one end of the first cover;

a second cover jointed to the hinge,

wherein each of the first operation lever and the second operation lever includes;

a portion positioned above the first cover; and

another portion positioned below the first cover.

2. The working machine according to claim 1, wherein at least one of the first cover and the second cover includes a first plate and a second plate, and forms a space for housing air between the first plate and the second plate.

3. The working machine according to claim 1, wherein the second cover extends from the hinge below with respect to the first cover.

4. A working machine comprising:

a machine body;

an actuator;

a control valve to control a hydraulic operation fluid, the hydraulic operation fluid being used for operating the actuator;

a support base disposed on a front side of the machine body, the support base including;

an attachment portion attached to a bottom portion of the machine body;

a leg portion standing upward from the attachment portion; and

a mount portion disposed on an upper side of the leg portion, the mount portion being configured to mount the control valve; and

a pedal disposed to left and another pedal disposed to right each configured to operate the control valve,

wherein the control valve is mounted on the mount portion between the pedal disposed to left and the other pedal disposed to right in a machine width direction.

5. The working machine according to claim 4,

wherein the support base includes a pedal attachment portion for attachment of the pedal,

wherein the attachment portion includes:

an attachment portion disposed to left; and

another attachment portion disposed to right,

wherein the pedal attachment portion includes;

a pedal attachment portion disposed to left and disposed above the attachment portion disposed to left; and

another pedal attachment portion disposed to right and disposed above the other attachment portion disposed to right,

and wherein the control valve is mounted on the mount portion between the pedal attachment portion disposed to left and the other pedal attachment portion disposed to right in the machine width direction.

6. The working machine according to claim 4, comprising:

a support shaft having an axis extending along the machine width direction;

a first cylindrical member and a second cylindrical member capable of turning about the axis of the support shaft,

the first cylindrical member being arranged below the other pedal disposed to right and linked with the other pedal disposed to right,

the second cylindrical member being arranged below the pedal disposed to left and linked with the pedal disposed to left; and

a link jointing the control valve to the first cylindrical member and the second cylindrical member.

7. The working machine according to claim 4, comprising:
