Claim 1

Independent Claim 334 words

In a lawn mower towing assembly including a leading vehicle and a trailing vehicle, each vehicle having a longitudinal front-to-rear axis, a hitch assembly comprising: (a) a leading hitch device comprising leading bracket means for connection to the rear portion of a leading vehicle, and an elongated draw bar extending transversely from said bracket means, laterally of the longitudinal axis of the leading vehicle, and terminating in a free end portion, (b) means securing said leading bracket means to the rear portion of the leading vehicle, (c) a trailing hitch device comprising a trailing bracket bar for connection to the front portion of a trailing vehicle, and a single clevis member, (d) means securing said trailing bracket bar to the front portion of the trailing vehicle in operative position, (e) said single clevis member comprising vertically spaced upper and lower arms and a bight member connecting said upper and lower arms, (f) means securing said bight member to said trailing bracket bar so that said upper and lower arms project forwardly in a substantially vertical plane, (g) said draw bar having a vertical journal hole extending through its free end portion, (h) said upper and lower arms terminating in free end portions including vertically aligned holes, (i) a pintle removably inserted substantially vertically through the holes in said upper and lower arms and said vertical journal hole when said free end portion is between said upper and lower arms and said vertical journal hole is in registry with said pintle, in operative position, (j) said journal hole being large enough to permit free pivotal movement of said draw bar about the vertical axis of said pintle, (k) said free end portion of said draw bar having a vertical dimension, the vertical spacing between said upper and lower arms being substantially greater than the vertical dimension of said free end portion of said draw bar to permit a limited amount of vertical independent motion between the leading and trailing vehicles connected by said hitch assembly.

Claim 2

Dependent Claim 334 words

In a lawn mower towing assembly including a leading vehicle and a trailing vehicle, each vehicle having a longitudinal front-to-rear axis, a hitch assembly comprising: (a) a leading hitch device comprising leading bracket means for connection to the rear portion of a leading vehicle, and an elongated draw bar extending transversely from said bracket means, laterally of the longitudinal axis of the leading vehicle, and terminating in a free end portion, (b) means securing said leading bracket means to the rear portion of the leading vehicle, (c) a trailing hitch device comprising a trailing bracket bar for connection to the front portion of a trailing vehicle, and a single clevis member, (d) means securing said trailing bracket bar to the front portion of the trailing vehicle in operative position, (e) said single clevis member comprising vertically spaced upper and lower arms and a bight member connecting said upper and lower arms, (f) means securing said bight member to said trailing bracket bar so that said upper and lower arms project forwardly in a substantially vertical plane, (g) said draw bar having a vertical journal hole extending through its free end portion, (h) said upper and lower arms terminating in free end portions including vertically aligned holes, (i) a pintle removably inserted substantially vertically through the holes in said upper and lower arms and said vertical journal hole when said free end portion is between said upper and lower arms and said vertical journal hole is in registry with said pintle, in operative position, (j) said journal hole being large enough to permit free pivotal movement of said draw bar about the vertical axis of said pintle, (k) said free end portion of said draw bar having a vertical dimension, the vertical spacing between said upper and lower arms being substantially greater than the vertical dimension of said free end portion of said draw bar to permit a limited amount of vertical independent motion between the leading and trailing vehicles connected by said hitch assembly.

Claim 3

Dependent Claim 59 words

The invention according to claim 1 in which said leading bracket means comprises a leading bracket bar for connection to the rear portion of the leading vehicle and a rearward projecting offset bar fixed to said leading bracket bar and to said draw bar, whereby said draw bar extends laterally behind the chassis and wheels of the leading vehicle.

Claim 4

Dependent Claim 39 words

The invention according to claim 1 in which said trailing bracket bar is vertical, and said means securing said bight member to said trailing bracket bar securing said bight member and said trailing bracket bar together in vertical alignment.

Claim 5

Dependent Claim 72 words

The invention according to claim 3 in which said trailing hitch device further comprises a trailing brace bar having first and second end portions, said first end portion being connected to the upper end portion of said trailing bracket bar so that said trailing brace bar declines rearwardly, and means securing said second end of said trailing brace bar to the trailing vehicle in a location spaced behind said trailing bracket bar.
