1. A work machine comprising:

a frame of the work machine;

an engine supported by the frame inside a machine compartment of the work machine;

an exhaust gas control device including a filter that collects particulates contained in exhaust gas discharged from the engine;

a compartment cover that defines the machine compartment;

a compartment cover supporting member that supports the compartment cover and is disposed on the frame;

an engine hood that is supported by at least the compartment cover supporting member and includes a top plate shielding the machine compartment above the engine, an opening formed at the top plate, through which the exhaust gas control device is lifted up out of the machine compartment, and a reinforcing member disposed at an edge of the opening, that bears a supporting load of the exhaust gas control device;

an exhaust gas control device supporting member that suspends the exhaust gas control device downward through the opening and supports the exhaust gas control device in a suspended state; and

an opening cover that is detachably mounted at the engine hood and closes off or opens up the opening, wherein:

the exhaust gas control device supporting member includes a mounting portion that is attached to the exhaust gas control device and a fastening portion that is supported by, and fastened to, the reinforcing member, and when the fastening portion is unfastened, the exhaust gas control device supporting member is removable above the opening together with the exhaust gas control device attached to the mounting portion.

2. A work machine according to claim 1 , wherein:

an L-shaped member that includes a frontward ranging portion ranging frontward and a downward ranging portion ranging downward, intersecting each other at a substantially right angle so as to form a substantially L-shaped section viewed from a side of the work machine, is disposed at a front end of the engine hood, and a front end of the reinforcing member extending along a front/rear direction is connected to a surface of the downward ranging portion located on a rear side;

the front end of the engine hood is supported with a lower surface of the frontward ranging portion set in contact with an upper surface of a hydraulic oil tank; and

a rear end of the engine hood is supported by the compartment cover supporting member.

3. A work machine according to claim 1 , wherein:

a height of the top plate is set smaller than the height of an upper surface of the opening cover.

4. A work machine according to claim 1 , wherein:

the exhaust gas control device supporting member includes a fastening member as the fastening portion, a mounting member as the mounting portion and an elastic member disposed between the fastening member and the mounting member, and the mounting member is supported by the fastening member via the elastic member.
