Abstract

A tractor includes: a driver seat on which a driver can sit; a hood 5 provided in front of the driver seat; and an antenna unit that receives satellite positioning information. When viewed from the front, an upper end portion of a ROPS and at least part of the antenna unit overlap with each other.

Claims (43)

1. A tractor comprising:

a driver seat on which a driver can sit; and

an antenna unit that receives satellite positioning information,

wherein when viewed from the front, an upper end portion of a rollover protection structure (ROPS) and at least part of the antenna unit overlap with each other,

wherein the ROPS has right and left vertical frame portions and a lateral frame portion that joins upper ends of the right and left vertical frame portions to each other,

when viewed from the front, at least part of the antenna unit and at least part of the lateral frame portion overlap with each other, and

wherein the antenna unit is disposed rearward of the lateral frame portion and a lower end of the antenna unit is below an upper end edge of the lateral frame portion.

2. The tractor according to claim 1 , wherein the ROPS is provided to the rear of the driver seat.

3. The tractor according to claim 1 , further comprising:

right and left raising/lowering link mechanisms that are provided in a rear part of the vehicle body and raise/lower a working device,

wherein the antenna unit is provided between a rear end portion of the driver seat and a rear end portion of the right and left raising/lowering link mechanisms in a side view.

4. The tractor according to claim 3 , wherein the antenna unit is provided between the right and left raising/lowering link mechanisms in a plan view.

5. The tractor according to claim 1 , wherein a roof that covers above the driver seat is attached to the ROPS.

6. A tractor comprising:

a driver seat on which a driver can sit;

an antenna unit that receives satellite positioning information; and

a support member extending forward or rearward from the lateral frame portion and supporting the antenna unit,

wherein, when viewed from the front, an upper end portion of a rollover protection structure (ROPS) and at least part of the antenna unit overlap with each other,

wherein the ROPS has right and left vertical frame portions and a lateral frame portion that joins upper ends of the right and left vertical frame portions to each other,

when viewed from the front, at least part of the antenna unit and at least part of the lateral frame portion overlap with each other, and

wherein wiring that connects the antenna unit and a controller for traveling control is drawn out from a wiring take-out position of the antenna unit at a high position, and this wiring is held by the support member or the lateral frame portion at an intermediate position between the antenna unit and the lateral frame portion.

7. The tractor according to claim 6 , wherein the support member has a mounting face on which the antenna unit is mounted, reinforcement frames are erected on both right and left ends of the mounting face, and the antenna unit is disposed at an intermediate position between the right and left reinforcement frames.

8. A tractor comprising:

a driver seat on which a driver can sit;

an antenna unit that receives satellite positioning information; and

wiring that connects the antenna unit and a controller for traveling control,

wherein, when viewed from the front, an upper end portion of a rollover protection structure (ROPS) and at least part of the antenna unit overlap with each other,

wherein the ROPS has right and left vertical frame portions and a lateral frame portion that joins upper ends of the right and left vertical frame portions to each other, and

wherein the wiring is routed along the vertical frame portion.

9. The tractor according to claim 8 , wherein

the vertical frame portion is hollow, and

the wiring is routed so as to pass through the inside of the vertical frame portion.

10. The tractor according to claim 9 , wherein

the vertical frame portion is configured to be foldable by swinging around a laterally oriented swing pivot, and

the wiring is routed so as to pass through the inside of a movable portion of the vertical frame portion above the swing pivot.

11. The tractor according to claim 10 , wherein the wiring is routed inside the vertical frame portion, and is routed from the inside of the vertical frame portion to the outside through a through hole provided above the swing pivot.

12. A tractor comprising:

a driver seat on which a driver can sit; and

an antenna unit that receives satellite positioning information,

wherein when viewed from the front, an upper end portion of a rollover protection structure (ROPS) and at least part of the antenna unit overlap with each other,

wherein a roof that covers above the driver seat is attached to the ROPS,

wherein the ROPS has right and left vertical frame portions and a lateral frame portion that joins upper ends of the right and left vertical frame portions to each other, and

when viewed from the front, the antenna unit is provided in a center portion of the lateral frame portion, and the roof is fixed to the lateral frame portion at locations closer to the vertical frame portions than the location where the antenna unit is provided in the lateral frame portion.
