| Abstract: |
A riding attachment is adapted to be connected to a self-propelled lawn mower for carrying a standing rider/operator behind the mower during operation of the mower. This riding attachment includes a mounting assembly, a tow bar assembly, and a riding assembly. One end of the tow bar assembly is pivotably connected to the mounting assembly to allow for rotation of the tow bar assembly about a first axis parallel to a plane of the mower and transverse to the direction of movement of the mower. The riding assembly is pivotally connected to the second end of the tow bar to allow the riding assembly to pivot about a second axis parallel to the plane of said mower and in the direction of movement of said mower. The riding attachment further includes a pivot limiting element that limits the pivoting of the riding assembly out of the plane of the mower to a predetermined limit angle. This riding attachment thus safely carries the operator behind the mower over uneven terrain, preventing dislodgement of the operator or overturning of the riding assembly on which the operator stands.

First Claim:
Show all 7 claims |
I claim:
1. A combination of a power driven lawn mower and a riding attachment connected to the lawn mower for carrying a rider standing on a platform in which said riding attachment comprises:
- a tow bar assembly pivotally connected to said mower for pivoting about a first axis essentially parallel to a mower plane and essentially transverse to the direction of movement of said mower, said tow bar assembly constrained against pivoting with respect to the mower about an axis essentially vertical;
- a riding assembly, including said platform, pivotally connected to said tow bar assembly for pivoting about a second axis which is defined by the tow bar assembly and is essentially parallel to the mower plane and parallel to the direction of movement of said mower, said riding assembly constrained against pivoting about an axis essentially vertical with respect to the tow bar assembly; and
- a pivot limiting element associated with said tow bar assembly for limiting the pivoting of said riding assembly about said second axis so that said riding assembly may freely pivot about said second axis as the riding attachment moves over uneven terrain but is prevented from rotating past a predetermined maximum displacement angle, thereby protecting said rider from dislodgment;
- wherein said tow bar assembly includes a tow bar, said riding assembly further including a support bar pivotally connected to said tow bar about said second axis, said pivot limiting element being connected to said tow bar and extending over and spaced from said support bar a distance sufficient to limit maximum pivoting of said support bar with respect to said tow bar to said predetermined maximum displacement angle.
