Ransomes, Sims and Jefferies 'Proconsul' Agricutural ploughs Types TS3, C, E and D

1. The four- and five-furrow share ploughs illustrated here are known by the manufacturers as their "Proconsul" ploughs, type TS3, C, E and D.  There are a number of different models of this type of plough; those in use by the Airfield Construction Branch of the RAF being listed below. It will be noted that there are two types of 5-furrow ploughs with the same type number, one having a 12 in cut and the other a 14 in cut similarly there are also two 4-furrow ploughs with the same number, one having a 12 in. cut and the other a 14 in. cut.  When referring to these ploughs therefore, the width of cut and the number of furrows should be quoted as well as the type number.  Although there are slight differences between ploughs having different type numbers these are of a minor nature, and unless it is otherwise stated, the fol1owing particulars apply equally to all of them.

Ransomes, Sims and Jefferies, spike tooth harrow, Model SAH74

1. The spike-tooth harrow is used to work the land to a fine tilth suitable for seeding, and again afterwards to cover the seeds.  When used on grass that has become firmly established it has a rejuvenating effect by loosening the soil on the surface.  It is usually built up from two or more sections, which are attached by short lengths of chain to a pommeltree provided with a draught ring for towing the implement over the ground;  if, however, only one section is used the pommeltree is dispensed with and the harrow is fitted with draught rods and rings.  Each section consists of four horizontal beams (balks) which run fore and aft from the attachment chains to the rear of the harrow and are connected together by flat bars (straps) so that the balks are spaced equally apart.  The balks and straps are joined together by the upper ends of the spike-teeth which are threaded and provided with nuts for this purpose; the lower ends being pointed to form the teeth of the harrow.  The shape of the balks is such that the attachment points for the straps, and consequently the positions of the spikes, are staggered so that each spike cuts a separate track.

MT required for transportation -

• The harrow may be towed short distances on grass land, runners or skids are fitted to one section, which is turned upside down and the other sections laid on top it.  In all other instances it should be loaded on to a suitable MT vehicle.

This item of equipment appears to have been added to the 2nd Edition by the issue of AL5.

2. The rotation of the road wheels operates the knife through a crankshaft in the gearbox and an external connecting-rod, when required, the crankshaft gear can be moved into a neutral position by a lever on the gearbox.

3. Provision is made also for the finger bar to be raised to the vertical position during transit or storage.

Green Gang Air Ministry 1939 and 1943 type.

1. These mowers are available to the Service in triple gang and quintuple gang form.  The arrangement for the quintuple form is shown in the dimension diagram; when required in triple form the large wheeled draw-bar and the two leading mowers are omitted from the assembly.

2. In principle, the 1943 mower is the same as the 1939 mower, but in construction, it differs slightly; ball bearings are used in the intermediate gear, axle assembly and wheel assembly on the 1939 model, and bushes are used for these assemblies on the 1943 model.

3. The cutting cylinder on each mower is driven from the land wheels by gearing enclosed in gear cases which form oil baths for lubricating the transmission.  An adjusting screw on each side of each mower provides an adjustment for setting the soleplate to obtain the correct clearance between the cutting cylinder and the bottom blade.

4. Each land wheel is fitted with pawls to release or engage the cutting gear and the pawls are set by disengaging two spring knobs on the wheel and turning an operating plate which releases or engages the pawls with the gear.

5. The cutting height is adjusted by disengaging the spring pin on the lilting lever at the rear of the mower, moving the lever to raise or lower the machine on the rear roller, then engaging the spring pin into an appropriate hole in the suspension stay to lock the cutter in the desired position.

6. The machines are set so that they cannot cut grass shorter than 2 inches from the ground, but by a simple modification they can be altered to cut to a minimum length of ¾ inch.  At its highest normal position the grass will be 5 inches to 6 inches in length after cutting.

7. The gang mowers are normally towed by a tractor.

Allen auto-scythe, Model T & Mark 2

Model T Mark 2

1. The Model T machine is a two-wheeled, self-propelling type of mower which is driven by a Villiers Mark 25C two-stroke, air cooled engine.

2. Ratchets are fitted to the centre on the outside of each wheel and two pawls on each wheel engage the ratchet; one pawl can be held in a disengaged position by means of a pawl catch; thus permitting the wheel to free-wheel in one direction.  When one pawl on each wheel is held in the disengaged position, the machine can be turned sharply and manoeuvred with ease. When both pawls are engaged on both wheels there is a fixed drive and the machine will keep on a straight course.

3. The cutting mechanism comprises a finger bar and a reciprocating knife bar.  The finger bar is normally set centrally to the machine, but it is drilled at both ends so that it can be offset either to the right or to the left; right-hand or left-hand knife bars are required to modify the machine for offset cutting.

4. The Mark 2 machine is basically similar to the Model T machine with the following main differences: -

   1. The machine is driven by a Villiers Mark 11 C two-stroke, air cooled engine.

   2. Ratchet and pawl mechanism is not fitted to the wheels.

   3. Different handles are used which incorporate two cross members, and a bridle rod on each side of the machine.

   4. The finger bar cannot be adapted for offset cutting.

Bamlett grass cutter (towed), Model TM 1

1. The Bamlett grass cutter, Model TM1, is a two-wheeled machine which is normally towed by a tractor.   The machine comprises a finger bar with a reciprocating knife operated by a crankshaft and connecting-rod, driven by a bevel pinion from a cross shaft which is geared to both wheels.

2. Free-wheel mechanism is fitted to the drive, from the wheels to the cross shaft gear wheels, to free the drive on either wheel when turning the machine; the cutter bar is fitted to the right-hand side of the machine.

3. Three control levers, grouped together on the draw bar, provide the following actions: -

   1. Engage or disengage the knife bar drive.

   2. Tilt or level the cutter bar.

   3. Raise or lower the cutter bar by mechanical action, when operating the machine.

An additional lever, fitted to the main frame of the machine, is provided to raise or lower the cutter bar by hand.

4. The coupling on the end of the draw bar incorporates a spring release which automatically disconnects the mower from the tractor when the machine is obstructed; the spring release can be made inoperative by turning a capstan nut which is fitted to the side of the coupling.

5. During transit, or for storage purposes, the cutter bar can be raised to a vertical position, to reduce the width of the machine; a holding-up rod secures the cutter bar in the vertical position

Ransomes, Sims and Jefferies, mole-drainer, Model CIE

1. The mole drainer is employed to make passages below the surface of the ground for drainage purposes.  The implement is mounted on wheels and provided with a shin to which is attached the mole for making the drain hole; a disc coulter being provided to sever the turf  and leave an opening for the shin.  The depth at which the drainage hole is to be made can be set in any position down to 20 inches by means of a hand screw and the mole is then raised or lowered into the working position by a self-lift mechanism operated by cords from the tractor.  The mole can be fitted with an enlarger to increase the diameter of the hole so that the  main drain can be made larger than the subsidiary drains leading to it.

2. In addition to using the implement for making drainage passages it may also be employed to lay telephone wires etc, below the ground without disturbing the surface by trenching.  The wires to be laid are attached to the rear of the enlarger and are drawn through the hole which is made as the mole moves forwards.  The wires are run off from a drum or spool; the start and finish being at short trenches, which also serve is junction pits.
