Looking into the Department of Agriculture specification for machines under TAMS, some controversial decisions have been made. Most notably the 700mm clearance requirement for cultivation equipment – it essentially rules out 90% of the discs on the market today.

All machines must be fitted with appropriate road lighting for road use. For fertiliser spreaders, weight cell machines or machines with similar rate controls are eligible. The wording in the specification suggests that the global positioning system (GPS) must be exclusive to the fertiliser spreader. The wording also suggests that the GPS unit must be capable of controlling the spreading rate and width. The width control is common with many section control machines working already, but rate-controlled GPS is not all that common yet.

Tractor steering control

All GPS shall be of proprietary manufacture. The GPS steering control may be fitted to either a new tractor or retrofitted to an existing tractor.

The units shall be able to control the location of the tractor to within a distance of 200mm of the intended location. Systems with higher accuracy are permitted. The system shall be able to automatically guide the tractor along the correct path down the field parallel to the previous pass at the required distance. It is not required to be able to turn the tractor on the headland.

The GPS steering control unit shall include a display screen, GPS receiver, control unit and tractor steering control. The tractor steering control shall be either a steering wheel spinner system or connect directly into the tractor’s power steering system.

A steering wheel spinner is a unit that is connected to the steering wheel of the tractor and causes the steering wheel to turn.

For systems connected directly to the power-steering system, the steering wheel will not rotate during operation.

The control unit shall be able to record the path of the tractor and be able to link to external devices to upload relevant data, such as the path of the tractor and field details.

Lightbar systems or systems that do not control a tractor to within 200mm of the intended location are not acceptable for grant-aid.

Yield monitors for combine

All yield monitors for combines shall be of proprietary manufacture. The yield monitor systems may be fitted to either a new combine or retrofitted to an existing combine.

The units shall be able to record the location of the combine to within a distance of 200mm of the actual location and record the mass of grain being harvested. Systems with higher accuracy are permitted.

The yield monitor unit shall include a display screen, GPS receiver and control unit.

The control unit shall be able to record the path of the combine, width of cutting head and be able to link to external devices to upload relevant data, such as the path of the combine, field shape and dimensions, crop yield.

Sprayers

All sprayers shall be fully compliant with the European standard EN ISO 16119-2:2013 and also EN ISO 4254 and shall be fully CE marked. The CE mark shall be shown on the sprayer identification plate. In addition, all sprayers shall have the following elements:

  • Electronic control from within the cab.
  • Hydraulic boom height control.
  • Wash tank with minimum 10% capacity of main tank.
  • Clean water hand wash tank of minimum 15l capacity.
  • Chemical induction bowl with container wash.
  • Internal rinsing nozzle for cleaning the inside of the spray tank after spraying is completed.
  • Minimum of three boom segments.
  • The actual overall volume of the tank shall exceed the nominal volume by at least 5 %.
  • All GPS-controlled sprayers shall have boom segments not exceeding 3m and, at the end of each boom, the segments shall not exceed 750mm (three nozzles) in length. The GPS shall be capable of turning individual sections on and off during operation to prevent overlap of spraying.

    The GPS unit shall be able to record the path of the sprayer to within 200mm of the actual location and the control unit shall be able to record and upload information on application rates and locations to external devices.

    It is strongly recommended that all sprayers are fitted with triplet nozzle holders and low-drift nozzles. All sprayers shall be fitted with suitable road lighting.

    GPS for fertiliser spreaders

    All GPS shall be of proprietary manufacture or exclusive to the manufacturer. The GPS shall be an integral part of the new fertiliser spreader.

    The unit shall be able to control the rate of fertiliser application and the width of spread of the fertiliser to both left and right independently. In addition, the system shall control the turning on and off of the fertiliser spreader when approaching and leaving a headland.

    The unit shall be able to undertake all controls while the fertiliser spreader is in operation in the field. The GPS units may be fitted to either trailed or mounted fertiliser spreaders.

    The GPS shall include a display screen, GPS receiver, control unit and weighing system on the fertiliser spreader. The units shall have at least four nominal application widths, which can be switched between while in motion.

    The control unit shall be able to record the location and path of the fertiliser spreader to within a distance of 200mm of the actual location and record the application rate and spreading width across the field. Systems with higher accuracy are permitted.

    The system shall be able to upload relevant data to external devices so that a record of the fertiliser application rate and location may be made.
