Pump unit and working vehicle

A working vehicle comprising:

• a vehicle frame;
• a first pair of laterally disposed wheels supported by said vehicle frame;
• a second pair of laterally disposed wheels supported by said vehicle frame so as to be located away from said first pair of laterally disposed wheels in a fore and aft direction of said working vehicle;
• a working unit supported by said vehicle frame;
• a driving source supported by said vehicle frame;
• first and second motor units respectively and operatively connected to said first pair of laterally disposed wheels;
• and
• a pump unit supported directly or indirectly byialld vehicle frame so as to be operatively connected to said driving source, said pump unit arranged to supply and discharge hydraulic fluid into and from each of said first and second motor units, and take out driving power of said driving source and output the same as driving power for said working unit, said pump unit comprising:
• an input member operatively connected to said driving source;
• a first hydraulic pump body operatively connected to said input member;
• a pump case for accommodating said first hydraulic pump body;
• fluid connection ports disposed on an outside surface of said pump case for fluidly connecting said first hydraulic pump body with said first and second motor units;
• and
• a PTO unit accommodated within said pump case, said PTO unit comprising:
• a PTO shaft supported by said pump case so as to have an end extending outward from said pump case;
• and
• a clutch mechanism for selectively enabling and disabling transmission of driving power from said input member to said PTO shaft,
• wherein said first and second motor units are accommodated outside said pump case so as to be located away from said pump unit.
