Abstract

Combinations of agricultural implements are mounted to the front and rear of a tractor. The front of the tractor pushes a fertiliser preferably having its own source of power, to operate the delivery device. At the rear of the tractor is a cultivator with a plurality of soil working members that are rotatably connected to the power take off of the tractor. The cultivator is connected to a lifting hitch and a seed dispenser is pivotably connected to the rear of the cultivator and also connected to the upper point of the lifting device. Flexible chains interconnect the seed dispenser with the upper lifting point so that the dispenser can be raised with the cultivator by the lifting device. The dispenser is mounted on ground wheels which can power the operation thereof. At the rear of the cultivator a soil engaging roller is mounted which regulates the working depth of the cultivator and smooths the soil.

Claims

1. An agricultural implement combination comprising a tractor having a fertilizer attachment device connected to the front of said tractor, a cultivator with trailing seed drill coupled to a lifting hitch at the rear of said tractor, said fertilizer device having an elongated hopper which extends transverse to the intended direction of travel of the combination and said hopper housing a rotary delivery member on an operating shaft for the ejection of fertilizer from said hopper in front of the tractor, said delivery member being operated to dispense fertilizer at a spaced distance in front of said cultivator, said cultivator having a plurality of counter rotating soil-working members arranged in a transverse row and rotatable about upwardly extending shafts, said shafts being in driven engagement with a power take off of the tractor, said fertilizer being dispensed in front of soil displaced by said soil-working members and being evenly distributed with the soil at the rear thereof, coupling members interconnected to the front and the rear of said cultivator, the apices of said coupling members being connected by an arm of adjustable length, said seed drill being pivotally connected to a coupling member at the rear of the cultivator, a soil smoothing roller extending across the width of the combination, said roller having a plurality of elongated elements extending substantially parallel to the axis of rotation of said roller and said roller bEing pivotally connected to said cultivator behind the said row of soil-working members and in front of said drill, the working width of said elongated hopper being substantially equal to the working width of said cultivator.
