Abstract
Abstract A cultivator fender for being dragged along the ground by a cultivator vehicle to shield a row of crops from having earth, cultivated alongside the row by cultivators carried by the vehicle, thrown onto the row. The fender includes a pair of generally vertical elongate shields extending parallel to one another and spaced apart for being dragged along the ground by the vehicle on opposite sides of the row, suspension means adapted for connection to the cultivator, and a link interconnecting each shield and the suspension means. Articulating pivotal connections are provided between the forward end of each link and the suspension means and between the rearward end of each link and its shield to permit the swinging of the links relative to the suspension means and to permit swinging angular movement of the shields relative to the links in response to changing ground contours as the fender is dragged along the ground.

A cultivator fender for being dragged along the ground by a cultivator vehicle to shield a row of crops from having earth, cultivated alongside the row by cultivators carried by the vehicle, thrown onto the tow comprising: a pair of generally vertical elongate shields extending parallel to one another and spaced apart for being dragged along the ground by the vehicle on opposite sides of the row, the lower edges of the shields sliding over the ground; means bridging the shields above the shields and maintaining them in spaced-apart relation and in generally vertical position; suspension means adapted for connection to the cultivator; a link interconnecting each shield and the suspension means; means for enabling swinging angular movement of the shields relative to the links on a first generally horizontal axis extending transverse to the shields in response to changing ground contours as the fender is dragged along the ground, the last said means comprising an articulating pivotal connection between the rearward end of each link and its shield positioned forward of the center of the length of the shield and an articulating pivotal connection between the forward end of each link and the suspension means for swinging of the links relative to the suspension means on a second generally horizontal axis parallel to the first axis, said links being capable at all times of swinging about the pivotal connections at their forward ends and the shields being capable at all times of swinging about their pivotal connections at the rearward ends of the links whereby the shields are adapted to slide over the ground in contact therewith and the lower edges of the shields are adapted to follow the ground contour by pivoting of the links relative to the suspension means and pivoting of the shields relative to the links for effectively preventing earth cultivated alongside the row by the cultivator from being thrown onto the row and the forward ends of the shields are prevented from digging into the ground.

A cultivator fender for being dragged along the ground by a cultivator vehicle to shield a row of crops from having earth, cultivated alongside the row by cultivators carried by the vehicle, thrown onto the tow comprising: a pair of generally vertical elongate shields extending parallel to one another and spaced apart for being dragged along the ground by the vehicle on opposite sides of the row, the lower edges of the shields sliding over the ground; means bridging the shields above the shields and maintaining them in spaced-apart relation and in generally vertical position; suspension means adapted for connection to the cultivator; a link interconnecting each shield and the suspension means; means for enabling swinging angular movement of the shields relative to the links on a first generally horizontal axis extending transverse to the shields in response to changing ground contours as the fender is dragged along the ground, the last said means comprising an articulating pivotal connection between the rearward end of each link and its shield positioned forward of the center of the length of the shield and an articulating pivotal connection between the forward end of each link and the suspension means for swinging of the links relative to the suspension means on a second generally horizontal axis parallel to the first axis, said links being capable at all times of swinging about the pivotal connections at their forward ends and the shields being capable at all times of swinging about their pivotal connections at the rearward ends of the links whereby the shields are adapted to slide over the ground in contact therewith and the lower edges of the shields are adapted to follow the ground contour by pivoting of the links relative to the suspension means and pivoting of the shields relative to the links for effectively preventing earth cultivated alongside the row by the cultivator from being thrown onto the row and the forward ends of the shields are prevented from digging into the ground.
Claim 3
Dependent Claim
87 words
The cultivator fender of claim 1 including a pair of inclined planes each attached to an outwardly facing side of a respective shield for smoothing the earth cultivated alongside the row by the cultivator, each said inclined plane having a lower edge portion extending laterally outwardly from said side of the respective shield substantially level with the lower edge of the shield, and said inclined plane being located adjacent the rearward end of the respective shield and inclined upwardly in the forward direction of the respective shield.
Claim 4
Dependent Claim
67 words
The cultivator fender of claim 1 including a pair of resilient extensible members each connected at one end to a respective link and at the other end to a respective shield forward of the connection of the link to the shield and biasing the forward ends of the shields upwardly so as to assist in preventing the forward ends of the shields from digging into the ground.
Claim 5
Dependent Claim
27 words
The cultivator fender of claim 3 wherein the links have angular extensions and the resilient extensible members are tension springs connected between said extensions and the shields.
Claim 6
Dependent Claim
20 words
The cultivator fender of claim 1 including means limiting the pivotal movement of the links with respect to the shields.
Claim 7
Dependent Claim
24 words
The cultivator fender of claim 1 wherein said bridging means includes a yoke connecting the links so as to resist twisting of the fender.
Claim 8
Dependent Claim
22 words
The cultivator fender of claim 1 wherein each shield has a runner at the bottom thereof adapted to slide along the ground.
Claim 9
Dependent Claim
26 words
The cultivator fender of claim 7 including an upwardly extending post attached adjacent the rearward end of each shield whereby spraying apparatus may be mounted thereon.
Claim 10
Dependent Claim
32 words
The cultivator fender of claim 8 wherein the forward ends of the runners extend upwardly so as to assist in preventing the forward ends of the shields from digging into the ground.
Claim 11
Dependent Claim
23 words
The cultivator fender of claim 1 wherein the forward ends of the shields are beveled so as to resist digging into the ground.
Claim 12
Dependent Claim
33 words
The cultivator fender of claim 2 wherein each inclined plane has a flange extending generally horizontally rearward at its said lower edge portion substantially level with the lower edge of the respective shield.
Claim 13
Dependent Claim
22 words
The cultivator fender of claim 1 wherein the bridging means is adjustable for adjusting the spacing of the shields one from another.
Claim 14
Dependent Claim
158 words
A cultivator fender which comprises a rigid member having a pair of oppositely disposed elongate sheets and a pair of strapping members connecting the two sheets, the sheets being adapted to be dragged edgewise over the ground; an arched bridle having one end connected to pivot to one sheet and the other end attached pivotally to the other sheet, the arched bridle having a pair of projections, each on opposite sides of the said sheets; an adapter member having an upper end and lower end, the upper end being rigidly connected to a cultivator and the lower end being pivotally connected to the pair of projections of the arched bridle; a pair of springs connecting the arched bridle to the sheets; a pair of inclined planes disposed on opposite sides of said sheets for smoothing earth along the path of the shield; and means to limit the pivotal movement of the arched bridle with respect to the sheets.
