Machine suspension and height adjustment

An assembly for supporting a vehicle chassis on a wheel of the vehicle, the assembly comprising:

• a wheel attachment component for attaching the assembly to a wheel;
• a chassis attachment component for pivotably attaching the assembly to a chassis of the vehicle;
• a suspension component operably interposed between the wheel attachment component and the chassis attachment component;
• a first adjustment element coupled with the chassis attachment component and coupled with a first portion of the suspension component;
• a second adjustment element coupled with the chassis attachment component and coupled with the first portion of the suspension component, the first and second adjustment elements configured to shift the first portion of the suspension component between a plurality of operating positions relative to the chassis attachment component;
• and
• a single strut bar slidingly engaging the wheel attachment component and rigidly coupled with a second portion of the suspension component.

An agricultural machine comprising:

• a chassis;
• a plurality of wheels supporting the chassis above a ground surface;
• a motor for driving at least one of the wheels to thereby propel the machine along the ground surface;
• and
• a plurality of height adjustment assemblies, each assembly configured to support a portion of the chassis on one of the wheels and to selectively raise and lower the chassis relative to the ground surface, the height adjustment assemblies being remotely controlled by a user, each of the height adjustment assemblies including—
• a wheel attachment component for attaching the assembly to one of the wheels;
• a chassis attachment component for attaching the assembly to a chassis of the vehicle;
• a suspension component;
• a first adjustment element coupled with the chassis attachment component and coupled with a first portion of the suspension component;
• a second adjustment element coupled with the chassis attachment component and coupled with the first portion of the suspension component, the first and second adjustment elements configured to shift the first portion of the suspension component between a plurality of operating positions relative to the chassis attachment component;
• and
• a single strut bar coupled with the wheel attachment component and coupled with a second portion of the suspension component such that the suspension component regulates motion transfer between the first attachment component and the second attachment component.
