  • the pivotal movement of the tynes 16 on the arms is controlled by means of a set of second hydraulic cylinders 41 which are mounted between the arms 15 and the upper end of the respective tine 16 which extends above the pivotal mounting of the tyne to the arm.
  • the pitting implement is associated with a seeder of the form described in Australian Patent Specification 463139 and which comprises a cylindrical drum 30 rotatably supported upon an axle 33 supported between the free ends of a pair of rearwardly extending support arms 31 pivot ⁇ ally mounted to the arms of the frame 11.
  • a third pair of hydraulic cylinders 32 are mounted between the arms of the frame 11 and the support arms 31 such that when retracted, the drum is in frictional engagement with the wheels and when extended the drum is free of wheels (as shown in broken lines) in figure 2 .
  • the hydraulic cylinders are of the form such that when they are not under pressure, they are in the extended form.
  • the drum 30 is divided into four transversly spaced compartments such that a compartment is associated with one of the arms 15 of the pitting imple ⁇ ment.
  • Each compartment has a loading aperture provided in the side wall of the drum 30 and associated with a hinge door 36 which conceals and encloses the loading aperture.
  • each compartment is provided with at least one seed outlet aperture 37 through which seed is depos ⁇ ited onto the ground with rotation of the drum 30.
  • the outlet aperture 37 is associated with a movable plate 38 or like means across the aperture 37 which can serve in varying the dimensions thereof in accordance with the nature of the seed to be deposited.
  • each compartment is provided with an agitator 39 which takes the form of a U-shaped member having its free ends pivotable on the axle 33 of the drum such that the agitator member 39 will " remain in substantially vertical position with the compartment on rotation of the drum 30.
  • the agitator 39 serves in prevent ⁇ ing the tumbling of the seed within the compartment and the subsequent balling thereof and also assist in the delivery of seed from the seed outlet aperture.
  • Fluid pressure for each of the 1st, 2nd and 3rd sets of hydraulic cylinders 18, 41 and 32 is provided from the tractor vehicle through lines 24.
  • the fluid pressure to the first set of hydraulic cylinders 18 causing pivotal movement of the arms 15 is effected by a hydraulic direc ⁇ tional control valve 25 which is operated from a cam driven through a chain drive in one of the drum supporting arms 31 from one of the wheels 13 of the implement.
  • the first set of hydraulic cylinders 18 comprises one pair of the outermost cylinders and another pair consisting of the inner-most cylinders. Each pair of cylinders are connected in series whereby fluid displaced from one of the cylinders by extension of the cylinder is introduced into the other cylinder to e.ffect extension of the other cylinder.
  • the pairs of cylinders are interconnected in series whereby fluid displaced from one of the cylinders from the one pair of cylinders by retraction thereof is introduced to one of the cylinders of the other pair of cylinders to effect extension of that one cylinder.
  • the directional control valve 25 serves in switching the direction of fluid flow to the cylinder to cause periodic retraction and extension of the one pair of cylinders and subsequent extension and retraction of the other pair of cylinders.
  • the switching of the control valve is effected by means of a cam follower associated with the cam which is driven through the chain drive from the drum 30 and which is located in the supporting arm 31 for the drum 30.
  • the action of the directional control valve is such that fluid is supplied to the one pair of first hydraulic cylinders to raise the arms 15 and lift the tynes from the soil or fluid is supplied to the other pair of first hydraulic cylinders to lower the arms 15 such that the tynes become engaged with the soil.
  • the movement of the one pair of arms 15 is out of phase by 180 with the movement of the other pair of arms 15.
  • the tynes 16 are caused to move downwardly into engagement with the soil and then upwardly away from the soil to produce a pit in the soil with each downward movement.
  • each arm 15 - may be varied such that the spacing and length respectively of the pits produced by the tines can be varied.
  • the ampli ⁇ tude of the movement of each arm can be adjusted by means of the stops 19 so that the depth of the pits and the ground clearance of the tynes can be varied.
  • the pits produced by the implement are staggered.
  • the effect of such is to reduce the possibility of erosion by run-off due to the pits produced by the implement becoming interconnected and forming channels.
  • the alternate engaging of the tynes with the soil serves in achieving a substantially constant draft load on the tractor vehicle since the pair of tynes are at most times engaged with the soil.
  • each of the tynes 16 is pivotally mounted to the arms 15 and a second hydraulic cylinder 41 controls the pivotal movement of the tynes.
  • Each of the second cylinders 41 are connected in parallel and are associated with a pressurised accumulator 43. On applica ⁇ tion of fluid pressure to the second cylinders 14, the tynes are pivoted to their forward most position. In use, if one of the tynes engages an obstruction and excessive pressure is produced in the respective second hydraulic cylinder 41, the accumulator will accommodate the increased pressure and will enable the tyne to pivot rearwardly on the arm to clear the obstruction.
  • the third set of hydraulic cylinders 32 are connected in parallel to the second set of hydraulic cylinders 41 and with applica ⁇ tion of fluid pressure, will retract and bring the drum 30 into frictional engagement with the wheels 13.
  • the direc ⁇ tional control valve switches the flow of fluid to the first set of hydraulic cylinders to cause the tynes 15 to alternately periodically reciprocate into and out of engagement with the ground. Since the movement of the tynes to produce the pits in the ground is effected through a chain drive from the drum 30, the speed of switching effected by the direction control valve is cali ⁇ brated to the rotation of the drum 30 such that the seed from the apertures 37 in the drum 30 is deposited into the pits formed by the tynes.
  • a seeding implement is produced which is capable of providing a favourable envir ⁇ onment for the deposited seed and which provides a substan ⁇ tially constant draft load on the tractor vehicle and which is capable of simultaneously depositing a number of different seed types.
