Abstract
Abstract An implement to be mounted forward of a farm vehicle and including structural members that are vertically adjustable. Vine deflecting members are slidably mounted to the structural members to allow lateral adjustment of the deflecting members relative to the wheels of the vehicle. The deflecting members lift encountered vines and then push them laterally away from the path of the vehicle to permit its free passage.

An implement for turning vines out of the path of an approaching vehicle, comprising, in combination: a. a stationary support frame connected to a vehicle wherein said vehicle has a front end and a forward direction of movement, said frame extending in the forward direction of movement from said front end and including a beam arranged both transversely to the forward direction of movement and forwardly of the front end of the vehicle; b. an elevatable assembly including a fluid cylinder having a one end pivotally connected to the frame and a second end pivotally connected to a link member which is in turn fixedly connected to a bight portion of a U-shaped crank journaled to the frame for being pivotally moved by the cylinder and having arm portions forming a bell crank with the link, a free end of the arm portions pivotally attached to an actuator link member wherein said actuator link member is pivotally connected to an intermediate point of a first link member of a parallelogram linkage, and second and third link members forming two sides of the parallelogram linkage arranged parallel to one another and connected to the first link member, one of the second and third link members mounted on the frame and the beam mounted on the other for swinging movement therewith; and c. a deflecting assembly mounted on said beam and having first and second deflecting devices, each device including a vertical shank having a lower end which forms a means for engaging a vine and lifting the same, and a deflecting member connected at a one end to the shank adjacent the lower end thereof, the member of said first deflecting device diverging from the member of the second deflecting device and extending toward the front end of the vehicle, each deflecting member separately mounted on said beam and selectively, independently movable therealong laterally of the vehicle for varying the position thereof, wherein there is a spacing between said first and second deflecting devices which forms adjustable means for turning a vine out of a path of an associated wheel of the vehicle.
