The engine has an output axis which extends in a front and back direction of the bulldozer. The pump assembly includes a plurality of hydraulic pumps. The hydraulic pumps are disposed behind the engine and are disposed to line up with each other in the front and back direction. The pump assembly is connected to the engine. The engine auxiliary is disposed behind the engine and is mounted to the engine. The connecting member connects the engine and the engine auxiliary. ## Claims ### Claim 1 A bulldozer comprising: an engine having an output axis which extends in a front and back direction of the bulldozer, the engine further having a flywheel; a pump assembly connected to the engine, and including a plurality of hydraulic pumps, the hydraulic pumps being disposed behind the engine and line up with each other in the front and back direction, the pump assembly connected to the engine via the flywheel which is disposed in front of the pump assembly; an engine auxiliary disposed behind the engine above the flywheel and being mounted to the engine, the engine auxiliary having a fuel filter and a crank case ventilation device; a connecting member connecting the engine and the engine auxiliary; and a bracket to which the engine auxiliary is attached, the bracket being disposed above the flywheel and attached to the flywheel, with the fuel filter of the engine auxiliary being attached to one side portion of the bracket and the crank case ventilation device of the engine auxiliary being attached to the other side portion of the bracket. ### Claim 2 (depends on 1) The bulldozer according to claim 1, further comprising: a linking member linking an upper portion of the bracket and the engine. ### Claim 3 (depends on 1) The bulldozer according to claim 1, wherein the engine auxiliary further has an engine control unit which is attached to the bracket between the fuel filter and the crank case ventilation device. ### Claim 4 (depends on 3) The bulldozer according to claim 3, wherein the bracket includes a plate section which extends in the up and down direction and in the left and right direction and to which the engine control unit is attached, a first side surface section which is linked to one side portion of the plate section and to which the fuel filter is attached, a second side surface section which is linked to the other side portion of the plate section and to which the crank case ventilation device is attached, and a base surface section to which the flywheel is attached. ### Claim 5 (depends on 1) The bulldozer according to claim 1, further comprising: an engine cover for covering the engine, and an inspection window provided in a side surface of the engine cover, and the engine auxiliary being disposed to face the inspection window. ### Claim 6 (depends on 2) The bulldozer according to claim 2, further comprising: an engine cover for covering the engine, and an inspection window provided in a side surface of the engine cover, and the engine auxiliary being disposed to face the inspection window. ### Claim 7 (depends on 3) The bulldozer according to claim 3, further comprising: an engine cover for covering the engine, and an inspection window provided in a side surface of the engine cover, and the engine auxiliary being disposed to face the inspection window. ### Claim 8 (depends on 4) The bulldozer according to claim 4, further comprising: an engine cover for covering the engine, and an inspection window provided in a side surface of the engine cover, and the engine auxiliary being disposed to face the inspection window.
