Abstract:
A modified field finishing land plane, comprising:a. Two elongated girders orientated horizontally in parallel alignment forming a V-shaped main frame for said land plane,said main frame girders converging to form a front end of said land plane,said main frame girders separating into a widened rear end of said land plane,said converging girders at said front end of said land plane pivotably attached to a pair of yoked, steerable rollers,said yoke of said front end steerable rollers fastened to a vehicular-type tow bar,said widened rear end of said main frame affixed to a rear crosswise member,said rear crosswise member extending a portion outward past said affixment to said main frame on both sides,said extended portions being hinged-on support sections for individual rear rollers affixed by a yoke to swivel at outer terminal ends of said support sections;b. an elongated scooping bucket centrally affixed crosswise under said V-shaped frame of said land plane, said scooping bucket structured in three sections including a rotatable first bucket section, a fixed second bucket section, a rotatable third bucket section, said second fixed bucket section being center support for pivotal attachment of said first and said third bucket sections that extend outward on each side sufficiently clear of said V-shaped frame of said land plane to be rotated from a substantially horizontal position to a substantially vertical position narrowing the width of said land plane centrally for road towing safety;c. means for rotating said rotatable first and third bucket sections from a substantially horizontal original position to a substantially vertical position and returning said bucket sections to said original position;d. safety means for temporary maintenance of said rotatable first and third bucket sections in said substantially vertical position;e. at least one pair of road wheels useful on and off public roads;f. means for raising said road wheels allowing said scooping bucket ground contact for field use of said land plane, said means further providing lowering said road wheels for on-road towing of said land plane;g. means for narrowing said rear cross member at said extended hinged-on support sections for said rear rollers;h. safety means for temporarily holding said yoked individual rear rollers in a fixed position;i. means for shielding said main frame converging front end and said pivotal attachment to said pair of yoked, steerable rollers;j. means for providing support and shock resistance between said shielding means and said vehicle tow tongue.
