1. Curb forming apparatus comprising:a device for receiving and pushing hardenable material through a channel defined by a mold of the device to form a curb having an outer surface; a steering assembly attached to the device comprising a steering rod having a first end coupled to a first wheel support and a second end coupled to a second wheel support; the steering rod movable between a first steering position and a second steering position; the first and second wheel supports directed in a first direction in the first steering position of the steering rod; the first and second wheel supports directed in a second direction in the second steering position of the steering rod; the first direction being different from the second direction; a stop, carried by the device, located adjacent the steering rod between the first and second ends thereof; a hole through the steering rod between the stop and one of the first and second ends of the steering rod; and a pin removably couplable to the hole for interacting with the stop in response to movement of the steering rod for limiting movement of the steering rod between its first and second steering positions; a wheel attached to one of the first and second wheel supports; and an attached ratchet assembly permitting rotation of the wheel in only one direction. 2. Curb forming apparatus of claim 1, further comprising:first and second opposing parallel guides attached to the first and second wheel supports, respectively; and the first end of the steering rod reciprocated to the first guide and the second end of the steering rod reciprocated to the second guide. 3. Curb forming apparatus of claim 1, further comprising:a first member rotated to the device; and means interacting between the first member and the first wheel support, in which rotation of the first member urges reciprocal movement of the first wheel support. 4. Curb forming apparatus of claim 1, further comprising:a second member rotated to the device; and means interacting between the second member and the second wheel support, in which rotation of the second member urges reciprocal movement of the second wheel support. 5. Curb forming apparatus of claim 1, further comprising an attached brake movable between a first position away from the wheel and a second position engaging the wheel inhibiting it from rotating.6. A curb formed with the curb forming apparatus of claim 1.7. Curb forming apparatus comprising:a device for receiving and pushing hardenable material through a channel defined by a mold of the device to form a curb having an outer surface; and a steering assembly attached to the device comprising a steering rod having a first end coupled to a first wheel support and a second end coupled to a second wheel support; the steering rod movable between a first steering position and a second steering position; the first and second wheel supports directed in a first direction in the first steering position of the steering rod; the first and second wheel supports directed in a second direction in the second steering position of the steering rod; the first direction being different from the second direction; a stop, carried by the device, located adjacent the steering rod between the first and second ends thereof; a hole through the steering rod between the stop and one of the first and second ends of the steering rod; and a pin removably couplable to the hole for interacting with the stop in response to movement of the steering rod for limiting movement of the steering rod between its first and second steering positions. 8. Curb forming apparatus of claim 7, further comprising:first and second opposing parallel guides attached to the first and second wheel supports, respectively; and the first end of the steering rod reciprocated to the first guide and the second end of the steering rod reciprocated to the second guide. 9. Curb forming apparatus of claim 8, further comprising:a first member rotated to the device; and means interacting between the first member and the first wheel support, in which rotation of the first member urges reciprocal movement of the first wheel support. 10. Curb forming apparatus of claim 8, further comprising:a second member rotated to the device; and means interacting between the second member and the second wheel support, in which rotation of the second member urges reciprocal movement of the second wheel support. 11. Curb forming apparatus of claim 7, further comprising:a wheel attached to one of the first and second wheel supports; and an attached ratchet assembly permitting rotation of the wheel in only one direction. 12. Curb forming apparatus of claim 11, further comprising an attached brake movable between a first position away from the wheel and a second position engaging the wheel inhibiting it from rotating.13. A curb formed with the curb forming apparatus of claim 7.14. Curb forming apparatus comprising:a device for receiving and pushing hardenable material through a channel defined by a mold of the device to form a curb having an outer surface; and a steering assembly attached to the device comprising: first and second wheel supports reciprocated to the device; first and second opposing parallel guides attached to the first and second wheel supports, respectively; a steering rod having a first end reciprocated to the first guide and a second end reciprocated to the second guide the steering rod movable between a first steering position and a second steering position; the first and second wheel supports directed in a first direction in the first steering position of the steering rod; the first and second wheel supports directed in a second direction in the second steering position of the steering rod; the first direction being different from the second direction; a stop, carried by the device, located adjacent the steering rod between the first and second ends thereof; a hole through the steering rod between the stop and one of the first and second ends of the steering rod; and a pin removably couplable to the hole for interacting with the stop in response to movement of the steering rod for limiting movement of the steering rod between its first and second steering positions. 15. Curb forming apparatus of claim 14, further comprising:a first member rotated to the device; and means interacting between the first member and the first wheel support, in which rotation of the first member urges reciprocal movement of the first wheel support. 16. Curb forming apparatus of claim 14, further comprising:a second member rotated to the device; and means interacting between the second member and the second wheel support, in which rotation of the second member urges reciprocal movement of the second wheel support. 17. Curb forming apparatus of claim 14, further comprising:a wheel attached to one of the first and second wheel supports; and an attached ratchet assembly permitting rotation of the wheel in only one direction. 18. Curb forming apparatus of claim 17, further comprising an attached brake movable between a first position away from the wheel and a second position engaging the wheel inhibiting it from rotating.19.
