Abstract

Self-propelled vehicles for supporting and operating a device are disclosed. Example devices include agricultural devices. The vehicle includes mounting arms that allow the device to be extended forward or rearward of the vehicle. In some embodiments, the device is releasably coupleable to the vehicle. In some embodiments, the vehicle includes rear drive wheels and front caster wheels.

First claim

What is claimed is:

1. A self-propelled vehicle capable of supporting and operating a baler, the vehicle having a longitudinal axis and comprising:
a chassis;
a front wheel connected to the chassis;
a rear wheel connected to the chassis; and
a device mount capable of releasably attaching the baler, the device mount comprising:
a mounting arm having a first mounting surface and a second mounting surface capable of connecting to the baler, the mounting arm being pivotally mounted to the chassis to move the baler along the longitudinal axis between:
a working position wherein the baler is mounted to the mounting arm at the first and second mounting surfaces;
an extended position wherein the baler is coupled to the mounting arm at only the first mounting surface, the extended position being disposed behind the working position relative to the longitudinal axis; and
an intermediate position between the working position and the extended position wherein the baler is mounted to the mounting arm at the first and second mounting surfaces.

2. The self-propelled vehicle as set forth in claim 1 in combination with the baler, the baler having a mounting member removably connected to the mounting arm of the device mount.

3. The self-propelled vehicle as set forth in claim 2 wherein the baler comprises a load cell, the load cell being the mounting member.

4. The self-propelled vehicle as set forth in claim 2 , the baler having a front and a rear, wherein, as the baler moves between the working position to the extended position, the center of gravity of the baler shifts toward the rear of the baler relative to the longitudinal axis to allow the front of the baler to be tipped upward when in the extended position.

5. The self-propelled vehicle as set forth in claim 1 wherein the mounting arm is a first mounting arm, the device mount comprising a second mounting arm, the second mounting arm being pivotal to move the baler between the working position, intermediate position and extended position.

6. The self-propelled vehicle as set forth in claim 1 wherein the first and second mounting surfaces each define a notch in the mounting arm for receiving the baler.

7. The self-propelled vehicle as set forth in claim 1 wherein the mounting arm is a first mounting arm, the device mount comprising a second mounting arm, the second mounting arm being pivotal to move the baler between the working position, intermediate position, and extended position, the second mounting arm also having first and second mounting surfaces for connecting to the baler, the first and second mounting surfaces of the first and second mounting arms being the only surfaces that support the baler when moving the baler between the working position, intermediate position, and extended position.

8. The self-propelled vehicle as set forth in claim 1 wherein the front wheel is a first front wheel and the rear wheel is a first rear wheel, the vehicle further comprising a second front wheel connected to the chassis and a second rear wheel connected to the chassis, the front wheels being caster wheels and the rear wheels being drive wheels.

9. The self-propelled vehicle as set forth in claim 1 further comprising a vehicle-device interface for powering and/or controlling the baler, the interface being releasably coupleable to the baler, and wherein the vehicle-device interface is configured to allow the vehicle to communicate with the baler to control the baler when the vehicle is coupled to the baler.

10. The self-propelled vehicle as set forth in claim 9 wherein the vehicle-device interface comprises a power adapter and/or communications adapter, the adapter being releasably coupleable to the baler.
