Abstract
Abstract A cultivator assembly for treating adjacent crop rows in which a mounting bracket is secured to a cultivator frame, and a parallelogram linkage provided by a pair of spaced substantially parallel wing arms, pivotally connect a side frame to each side of the mounting bracket, the side frames being adapted for location at the sides of adjacent crop rows, and having groundengaging members for following the contour of the ground. Croptreating devices such as flame or spray nozzles are carried by the side frames for treating the adjacent crop rows. Each side frame includes a pair of substantially vertical post members spaced in the direction of frame travel, and a pair of substantially horizontal pivot members extending between the post members, the pivot members being substantially vertically spaced. The mounting bracket includes at each side, a pair of substantially horizontal pivot members, the last said pivot members being vertically spaced. The parallelogram linkage includes a pair of parallel wing arms extending between and interconnecting the pivot members of each side frame and the pivot members on the associated side of the bracket. A fender is pivotally connected to each side frame for enabling substantially vertical movement of the fender to follow the ground contour. A brace assembly extends between and interconnects the fenders rearwardly of the pivotal connection of the fenders to the side frames, the brace assembly enabling separate and independent substantially vertical movement of the fenders while maintaining the fenders in a predetermined laterally spaced relationship.

Dependent Claim
80 words
a pair of substantially horizontal pivot members extending between the post members, the pivot members being substantially vertically spaced, g. the mounting bracket includes at each side a pair of substantially horizontal pivot members, the said pivot members being substantially vertically spaced, and h. the pair of parallel wing arms connecting each side frame to the mounting bracket extend between and interconnect the pivot members of each side frame and the pivot members on the associated side of the bracket.
Claim 5
Dependent Claim
80 words
a pair of substantially horizontal pivot members extending between the post members, the pivot members being substantially vertically spaced, g. the mounting bracket includes at each side a pair of substantially horizontal pivot members, the said pivot members being substantially vertically spaced, and h. the pair of parallel wing arms connecting each side frame to the mounting bracket extend between and interconnect the pivot members of each side frame and the pivot members on the associated side of the bracket.
Claim 6
Dependent Claim
45 words
a pair of cross bars, each of which is pivoted to the support member, one of the cross bars being pivoted to one fender and the other cross bar being pivoted to one fender and the other cross bar being pivoted to the other fender.
Claim 7
Dependent Claim
45 words
a pair of cross bars, each of which is pivoted to the support member, one of the cross bars being pivoted to one fender and the other cross bar being pivoted to one fender and the other cross bar being pivoted to the other fender.
Claim 8
Dependent Claim
56 words
a pair of cross bars, each of which is pivoted to the support member, one of the cross bars being pivoted to one fender and the other cross bar being pivoted to the other fender, the cross bars maintaining the fenders in laterally spaced relation and enabling separate and independent, substantially vertical movement of the fenders.
Claim 9
Dependent Claim
56 words
a pair of cross bars, each of which is pivoted to the support member, one of the cross bars being pivoted to one fender and the other cross bar being pivoted to the other fender, the cross bars maintaining the fenders in laterally spaced relation and enabling separate and independent, substantially vertical movement of the fenders.
