A middle mounted implement tractor utilizes a movable frame design in order to provide for middle mounting of implements on a tractor that can drive up to the implement, raise its front portion in the air, drive forward over the implement, and then lower the front portion to the ground and attach the middle mounted implement. This is accomplished utilizing a front frame assembly pivotably connected to a mounting frame assembly which mounts the implement; a frame mover mechanism that lifts the front frame and mounting frame; a middle frame which connects the cab, frame mover mechanism and related components; and a rear frame which attaches rear wheels, caster wheels, engine, etc. The front wheels can turn one hundred and eighty degrees and the tractor can easily interchange consumables via a carriage system that allows simple loading and unloading of tanks, etc. |

1. A middle mounted implement tractor, comprising:
a front frame assembly having a fixed forward frame assembly, a front wheel assembly, a left plurality of pivoting S arms and a right plurality of pivoting S arms; the front wheel assembly having a left front wheel assembly including a left front wheel and a right front wheel assembly including a right front wheel; a mounting frame assembly pivotably attached to the front frame assembly, the mounting frame assembly adapted to mount a middle mounted implement; wherein the front frame assembly is adapted to pivotably raise and lower relative to the mounting frame assembly such that the left and right front wheels can be raised and lowered relative to the mounting frame assembly; a movable frame assembly comprising the front frame assembly and the mounting frame assembly; a middle frame assembly movably attached to the mounting frame assembly and configured such that the movable frame assembly can be raised and lowered relative to the middle frame assembly; a rear frame assembly attached to the middle frame assembly and having a left rear wheel and a right rear wheel; wherein the front wheel assembly pivots on a pivot point attached at a center of the fixed forward frame assembly, the pivot point is adapted to allow the front wheel assembly to float side to side such that the left front wheel is allowed to move freely upwards while the right front wheel moves freely downwards, similarly, the pivot point is adapted to allow the right front wheel to move freely upwards while the left front wheel moves freely downwards, thus allowing a remainder of the tractor to remain level while traversing uneven ground; a left plurality of W arms pivotably connects a fixed forward frame assembly left portion to a mounting frame assembly left portion and a right plurality of W arms pivotably connects a fixed forward frame assembly right portion to a mounting frame assembly right portion; the left plurality of pivoting S arms are pivotably attached to the mounting frame assembly left portion and the right plurality of pivoting S arms are pivotably attached to the mounting frame assembly right portion; the fixed forward frame assembly extends laterally to either side of the pivot point and upwards to a left plurality of W arm attachment clevises on the fixed forward frame assembly left portion and to a right plurality of W arm attachment clevises on the fixed forward frame assembly right portion; wherein the mounting frame comprises a first implement attachment point and a second implement attachment point which are adapted to removably attach a middle mounted implement to the tractor; the middle frame comprises a tractor cab, a first plurality of dolly wheels, a second plurality of dolly wheels, attachments to a rear frame, and a vertical frame attachment assembly adapted to vertically raise and lower the movable frame assembly relative to the middle frame; and wherein the rear frame further comprises a first caster wheel, a second caster wheel, and attachments for an engine. |
