Utility vehicle with adjustable wheel base and wheel stance
A utility vehicle with adjustable wheel assemblies to accommodate different weight attachments selectively engageable with the vehicle. Adjustment assemblies are provided to engage each of the front wheel assemblies. Each adjustment assembly includes a guide plate, a first arm of a first length and a second arm of a second length. The operator will select the appropriate one of the first and second arms to secure to the guide plate and to one of the front wheel assemblies. The guide plates include holes therein for locking the selected one of the arms in a particular orientation. This is accomplished by inserting a pin through an aperture in the selected first or second arm and one of the holes in the guide plate. A first end of the selected first or second arm is secured to the guide plate and a second end thereof is engaged with the associated wheel assembly.

2. The utility vehicle as defined in claim 1 , further comprising a guide plate engaged with the frame; and wherein the selected first or second arm is engaged with the associated right or left front wheel assembly.
3. The utility vehicle as defined in claim 2 , wherein a first end of the selected first or second arm is detachably engaged with the associated right or left front wheel assembly.
4. The utility vehicle as defined in claim 3 , wherein a second end of the selected first or second arm is engaged with the associated one of the right or left wheel assemblies.
5. The utility vehicle as defined in claim 2 , wherein the guide plate defines a first hole therein and a second hole therein and the first and second holes are spaced from each other; and wherein the adjustment assembly includes a pin; and the pin is inserted through an aperture in the second end of the selected first or second arm and through one or the other of the first and second holes in the guide plate.
6. The utility vehicle as defined in claim 5 , wherein the guide plate defines an additional hole therein and the pin is selectively inserted through the aperture in the second end of the selected first or second arm and through the additional hole.
7. The utility vehicle as defined in claim 6 , wherein the first hole, second hole and additional hole are located at regular intervals from each other on the guide plate.
8. The utility vehicle as defined in claim 7 , wherein the first hole, second hole and additional hole are arranged in an arcuate pattern.
9. The utility vehicle as defined in claim 2 , wherein the guide plate includes a first projection that extends for a distance outwardly along a first portion of the frame.
10. The utility vehicle as defined in claim 9 , wherein the first projection is fixedly secured to the frame.
11. The utility vehicle as defined in claim 10 , wherein the guide plate further comprises a second projection spaced from the first projection and the second projection extends along a second portion of the frame and is secured thereto.
12. The utility vehicle as defined in claim 2 , wherein the guide plate further defines a central hole and a bolt secures a first end of the selected first and second arm to the guide plate and thereby to the frame.
13. The utility vehicle as defined in claim 12 , further comprising a second guide plate located parallel to and spaced apart from the guide plate; and wherein the first end of the selected one of the first and second arms is received between the guide plate and the second guide plate.
14. The utility vehicle as defined in claim 13 , wherein the second guide plate is secured to the frame.
15. An adjustment assembly for securing a wheel assembly to a frame of a zero-turn utility vehicle, said adjustment assembly comprising:
a guide plate adapted to be secured to the frame of the vehicle;
a first arm of a fixed first length; and
a separate and different second arm of a fixed second length; and wherein one or the other of the first and second arms is selectively engageable between the guide plate and the wheel assembly.
16. The adjustment assembly as defined in claim 15 , further comprising a second guide plate located spaced apart and parallel to guide plate such that a gap is defined between the guide plate and the second guide plate; and wherein the second guide plate is adapted to be secured to the frame of the vehicle; and wherein the selected one of the first and second arms is received in the gap and is detachably secured to the guide plate and second guide plate.
17. A method of adjusting a wheel base or wheel stance of a utility vehicle comprising the steps of:
securing first and second guide plates to a front portion of a frame of the utility vehicle a distance apart from each other;
providing a pair of first arms of a fixed first length and a separate and different pair of second arms of a fixed second length;
selecting a first one of the pair of first arms or of the pair of second arms;
engaging the selected first one of the pair of first or second arms with a first wheel assembly and the first guide plate;
selecting a second one of the pair of first arms or of the pair of second arms;
engaging the selected second one of the pair of first or second arms with a second wheel assembly and the second guide plate.
18. The method as defined in claim 17 , further comprising the step of:
engaging a first fastener with a first end of the selected first one of the pair of first or second arms and the first guide plate; and
engaging a second fastener with a first end of the selected second one of the pair of first or second arms and the second guide plate.
19. The method as defined in claim 17 , further comprising the step of engaging a second end of the selected first one of the pair of first or second arms and the first wheel assembly and engaging a second end of the selected second one of the pair of first or second arms with the second wheel assembly.
20. The method as defined in claim 17 , further comprising the step of:
selecting one of a plurality of spaced apart apertures in the first guide plate;
engaging a first fastener through an aperture defined in the selected first one of the pairs of first and second arms and into the selected one of the plurality of spaced apart apertures in the first guide plate;
selecting one of a plurality of spaced apart apertures in the second guide plate; and
engaging a second fastener through an aperture defined in the selected second one of the pairs of first and second arms and into the selected one of the plurality of spaced apart apertures in the second guide plate.
21. The method as defined in claim 17 , further comprising:
disengaging the selected first one of the pair of first or second arms from the first wheel assembly and the first guide plate; and
engaging the other of the first arm or the second arm with the first wheel assembly and the first guide plate.
22. The method as defined in claim 17 , further comprising:
disengaging the selected second one of the pair of first or second arms from the second wheel assembly and the second guide plate; and
engaging the other of the first arm or the second arm with the second wheel assembly and the second guide plate.
