a first support member supported by a first position and a second position disposed on the rear portion of the motor and having an opposite attachment portion, the opposite attachment portion being attached opposite to the attachment surface;
an elastic member attached to the first support member; and
a second support member configured to support the elastic member between the first position and the second position.

2. The working machine according to claim 1 , comprising:
a bumper portion disposed on an rear end of the working machine; and
a hydraulic hose disposed between the second support member and the bumper portion.

3. The working machine according to claim 1 , comprising:
a bonnet configured to cover a rear portion of the motor;
a ride control valve;
a bucket level control valve; and
a quick hitch valve, wherein
the ride control valve, the bucket level control valve, and the quick hitch valve are disposed on a side of the motor in front of the bonnet.

4. The working machine according to claim 1 , comprising:
a bonnet configured to cover a rear portion of the motor; and
an oil filter, wherein
the oil filter is disposed on a side of the motor in front of the bonnet.

5. A working machine comprising:
