Many crops are traditionally planted as small plants rather than from seed, either to extend the growing season by starting plants indoors, to avoid thinning, or to get more crops planted in one year. The Japanese have developed perhaps dte most energy-efficient transplanting mechanism, which they use largely for rice and tobacco. It is a two-wheel tractor with an automatic steering mechanism which guides the tractor while one man feeds plants into the transplanting mechanism.

We in North America are familiar only with tractor-drawn units. They can plant from one to lii or mere rows at a time, with one or two people feeding the transplanter per row. Often, a water tank is mounted on the hauling tractor, and plants are watered with either a continuous or intermittent flow as soon as they are set and firmed into the ground. One unit just described makes the planting hole with a water spray. Additional equipment might include cultivators or a fertilizer distributor.

A Semiautomatic Device For Planting Cassava Stem Cuttings on Ridges

From the Agricultural Engineering Depart ment at lie, Nigeria, G.A. Makaujuola reports the development of a mechanical device for planting cassava stem cuttings on freshly made ridges.

This device is a machine consisting of a disc ridge and semiautomatic planter which can be built as a multirow unit. It can be manufactured entirely locally (Nigeria) with the exception of the ridger discs ami bearings.

A two-row ridger in operation, pulling a planter behind it with a pipe joint.

Investigations revealed that cassava stem cuttings can be successfully planted on an unridged field with the New Holland transplanter, but it cannot be easily modified to plant on ridges.

The newly designed planting mechanism consists of a disc on which are mounted three rubber pieces cut from 75-millimeter, flat belting material. These rubber pieces serve as hands for holding the stem cuttings in position as the cuttings are pushed into the newly made ridge.

When cuttings reach the erect position they are released. The hands are kept closed by means of a roller which moves along the surface of a curved member. The cuttings are prevented from slipping during the planting process by a combination of the grip of the rubber hands and stops welded toward the center against which the top of the cuttings bear as they are pushed into the soil.

The planter is pulled behind the disc plow and planting discs are mounted on sliaits which are driven by chains directly from the implement land wheels. The sprocket on each of the land wheels is mounted on a sleeve which is bolted to the wheel hub. The sprockets on the planting disc shafts are mounted on a hub provided with a pawl arid ratchet device which allows power transmission in one direction only. This is to

make reversing possible. By varying the number of teeth on both sprockets, it is possible to alter the spacing along the rows. By moving the planting discs along their shafts and adjusting the (enter distance of the land wheels, it is possible to obtain different sparing«,between two adjacent rows,

Deluxe models are available with positive gauge wheel drive. The operators place the plant at the right depth while the machine sets the plant in the furrow, waters the roots, and packs the soil around the roots and stem. Models are available with a one- to four-row capacity,

A continuous or intermittent water supply is available with all Ellis Automatic Transplanters. The system uses two valves mounted on the seat bar between the operators. One valve is used to adjust the amount of water applied per plant while the other shuts the water

Mechanical Transplanters

The Mechanical Transplanter Company has a number of models ranging in size from a one-row to a four-row unit which can be attached to any tractor drawbar with a single pin. Everything is adjustable 011 these units, including seats, footrests, plant spacers, and water valves. The Flo Check watering system turns water on and off at the instant of setting. Water is not lost between plants and the amount oi water given each plant can be set by a wing nut adjustment control.

Plans for this home-built Texas Potato Transplanter we*e provided by the Texas Agricultural Extension Service of the Texas A if M University System in College Station, Texas. Bolting directly to a standard tractor frame, the unit digs a trench, has seats for two people to feed plants and soil compressors to fill in around plants and compact the soil. No -watering system is provided.

Holland Transplanters

All Holland Transplanters have adjustable packing wheels, a Start-rite water valve, blunt- or round-point digging shoes, plant stands and plant boxes, plant holders, and back-rested seats as standard equipment. Available units range in site from a special one-row, one-seater unit for garden tractors, to eight-seated, four-row planters. They are available as either tractor-mounted or tractor-drawn units with or without watering tanks, cultivators, and fertilizer distributors.

Kennco Plant Setters

Available in one-, two-, or three-row models, the Kennco plant setter passes over a completed bed (with or without plastic covering), punches a hole for a plant and a stake (if required), then waters the hole completely, and allows a riding attendant to place a hothouse seedling or seedbed-grown plant directly into the watered hole. Attendants ride at a comfortable position with all plants and controls directly available for rapid but thorough plant setting in each row. Experience has shown that using this method, replanting due to young plant attrition is extremely minimal. Watering controls consist of metering valves and on-off valves handled by the attendant.
