Abstract
Abstract A pair of self-propelled vehicles are positioned in spaced apart alignment on a field to establish a line of sight for an operator along an initial path of travel of a manually operated powered farm implement. Each of the self-propelled vehicles includes an electrically driven motor connected to a source of power for imparting movement to the self-propelled vehicle. Electrical controls, including a control device, are provided for independently actuating the electrically driven motor of each of the self-powered vehicles, in a selected sequence to impart movement to the self-propelled vehicle in a direction perpendicular to the line of sight to establish a subsequent line of sight. A regulating device on each vehicle deactuates the motor to regulate the length of movement of the vehicle.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
145 words
A method of guiding a manually operated powered farm implement in a path of travel comprising the steps of: a. positioning at least a pair of self-propelled vehicles carrying omnidirectionally visible signals on a field, spaced mutually in the desired direction of travel of the implement, for independent movement generally perpendicular to said desired direction; b. aligning said self-propelled vehicles to establish a line of sight along an initial path of travel for the operator of the manually operated powered farm implement; c. controlling said vehicles separately from the powered farm implement to cause said independent movement thereof through predetermined distances and in the selected sequence to establish a subsequent line of sight spaced from and generally parallel to the preceding line of sight; and d. regulating the length of said movements perpendicular to the preceding line of sight on each of said self-propelled vehicles.
Claim 2
Independent Claim
145 words
A method of guiding a manually operated powered farm implement in a path of travel comprising the steps of: a. positioning at least a pair of self-propelled vehicles carrying omnidirectionally visible signals on a field, spaced mutually in the desired direction of travel of the implement, for independent movement generally perpendicular to said desired direction; b. aligning said self-propelled vehicles to establish a line of sight along an initial path of travel for the operator of the manually operated powered farm implement; c. controlling said vehicles separately from the powered farm implement to cause said independent movement thereof through predetermined distances and in the selected sequence to establish a subsequent line of sight spaced from and generally parallel to the preceding line of sight; and d. regulating the length of said movements perpendicular to the preceding line of sight on each of said self-propelled vehicles.
Claim 3
Dependent Claim
25 words
