Abstract
Abstract g A working vehicle according to the present invention has a vertical engine mounted in an engine room covered by a hood, cooling air being drawn from above the engine and exhausted outwardly of a vehicle body through exhaust openings formed in a front surface of the hood. The working vehicle includes a fan disposed above the engine, and dust netting disposed above the fan. The dust netting is substantially box-shaped and includes an overhang portion extending rearwardly of the engine and downwardly.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
150 words
A working vehicle having a vertical engine mounted in an engine room covered by a hood, cooling air being drawn from above the engine and exhausted outwardly of a vehicle body through exhaust openings formed in a front surface of the hood, said working vehicle comprising: a radiator mounted above the engine: a fan operatively connected to the engine and positioned between said engine and said radiator for cooling said radiator; and dust netting mounted above said fan, wherein said dust netting is substantially box-shaped and includes an overhang portion extending rearwardly of said engine and a shield assembly plate fixed to a lower surface of said dust netting, said shield assembly plate having defined therein an opening for guiding the cooling air to said engine, and said radiator includes means for engaging with said opening in said shield assembly plate, whereby said dust netting is fixed to said radiator.
Claim 2
Dependent Claim
150 words
A working vehicle having a vertical engine mounted in an engine room covered by a hood, cooling air being drawn from above the engine and exhausted outwardly of a vehicle body through exhaust openings formed in a front surface of the hood, said working vehicle comprising: a radiator mounted above the engine: a fan operatively connected to the engine and positioned between said engine and said radiator for cooling said radiator; and dust netting mounted above said fan, wherein said dust netting is substantially box-shaped and includes an overhang portion extending rearwardly of said engine and a shield assembly plate fixed to a lower surface of said dust netting, said shield assembly plate having defined therein an opening for guiding the cooling air to said engine, and said radiator includes means for engaging with said opening in said shield assembly plate, whereby said dust netting is fixed to said radiator.
Claim 3
Dependent Claim
46 words
A working vehicle as defined in claim 1, wherein said overhang portion includes a horizontal overhang portion extending rearwardly of a rear end of said engine parallel to an upper surface of said radiator, and a lower overhang portion extending downward from said horizontal overhang portion.
Claim 4
Dependent Claim
23 words
A working vehicle as defined in claim 2, wherein said overhang portion and said lower overhang portion are formed integral with each other.
Claim 5
Dependent Claim
19 words
A working vehicle as defined in claim 3, wherein said lower overhang portion has a substantially horizontal lower surface.
Claim 6
Dependent Claim
65 words
A working vehicle as defined in claim 1, wherein said shield assembly includes first shields extending sideways relative to said vehicle body to cover a region above said engine, and a second shield extending transversely of said vehicle body along an inner surface of said hood in a position forward of said opening relative to said vehicle body so as to straddle said dust netting.
Claim 7
Dependent Claim
31 words
A working vehicle as defined in claim 1, further comprising elastic elements fixedly connected between said shield assembly and said radiator for preventing entry of hot air and for suppressing noise.
Claim 8
Dependent Claim
184 words
A working vehicle having a vertical engine mounted in an engine room covered by a hood, cooling air being drawn from above the engine and exhausted outwardly of a vehicle body through exhaust openings formed in a front surface of the hood, said working vehicle comprising: a radiator mounted above the engine; a fan operatively connected to the engine and positioned between said engine and said radiator for cooling said radiator; dust netting mounted above said fan for covering said fan against dust; and control panel rearward of said engine relative to said vehicle body, said control panel defining a rear wall of the engine room and having defined thereon intake openings through which cooling air is drawn, wherein said dust netting is substantially box-shaped and includes an overhang portion, said overhang portion including a horizontal overhang portion extending rearward of of said engine relative to said vehicle body and parallel to an upper surface of said radiator, and a lower overhang portion extending downward from said horizontal overhang portion, said lower overhang portion being positioned adjacent said intake openings of said control panel.
Claim 9
Dependent Claim
184 words
A working vehicle having a vertical engine mounted in an engine room covered by a hood, cooling air being drawn from above the engine and exhausted outwardly of a vehicle body through exhaust openings formed in a front surface of the hood, said working vehicle comprising: a radiator mounted above the engine; a fan operatively connected to the engine and positioned between said engine and said radiator for cooling said radiator; dust netting mounted above said fan for covering said fan against dust; and control panel rearward of said engine relative to said vehicle body, said control panel defining a rear wall of the engine room and having defined thereon intake openings through which cooling air is drawn, wherein said dust netting is substantially box-shaped and includes an overhang portion, said overhang portion including a horizontal overhang portion extending rearward of of said engine relative to said vehicle body and parallel to an upper surface of said radiator, and a lower overhang portion extending downward from said horizontal overhang portion, said lower overhang portion being positioned adjacent said intake openings of said control panel.
Claim 10
Dependent Claim
57 words
A working vehicle as defined in claim 7, further comprising a shielding plate for intercepting heat radiating from said radiator and said engine, said shield plate being disposed rearward of said engine and forward of said overhang portion relative to said vehicle body for guiding cooling air drawn in through said intake openings to said overhang portion.
Claim 11
Dependent Claim
56 words
A working vehicle as defined in claim 8, wherein part of the cooling air drawn in through said intake openings is guided along said shielding plate to said overhang portion, and flows through said dust netting and said fan to be exhausted out of said vehicle body through said exhaust opening formed forwardly of said hood.
Claim 12
Dependent Claim
32 words
A working vehicle as defined in claim 7, wherein at least one of said intake openings is located on said control panel lower than a lowermost portion of said lower overhang portion.
