Electrical operated MANIFOLD valves (optional equipment) One or more MANIFOLD valve(s) can be electrically operated via a control box in the tractor cabin. These can only be operated manually if the power to the valve motor is disconnected.

  • Page 20: Hardi Filler

    The operating unit is constructed of modules and is electrically controlled via a remote control box. The built-in HARDI-MATIC ensures a constant volume per hectare of the liquid (l/ha) at varying forward speed within the same gear when the number of P.T.O. revolutions are between 300-600 r.p.m. (pump 540 r.p.m) or 650-1100 r.p.m. (pump 1000 r.p.m.).

  • Page 21: Boom

    3 - Description Boom Boom and terminology The sprayer can be fitted with VHY or VHZ boom. Both booms are supported by a trapeze which is fitted to the tank frame. The trapeze helps the boom to stay horizontal when unfolded and it protects the boom against vibrations and shocks when driving on uneven ground.

  • Page 22: Equipment

    3 - Description Equipment Driving technique for STEER and SELF TRACK A trailer with articulating drawbar (TRACKER) behaves differently than a normal trailer. In tracking position the vehicle centre of gravi- ty is displaced further more compared to the vehicle centre line of a normal trailer.

  • Page 23: Platform

    The actual tank level in the main tank can be observed on the tank level indicator. The scale is displayed in litres or Imp. gal/US gal. (cer- tain countries). ATTENTION! If extra high accuracy are needed HARDI FILLME- TER can be fitted as optional equipment. Remote pressure gauge The remote pressure gauge is integrated in the platform.

  • Page 24: Mudguards (Optional Equipment)

    3 - Description Mudguards (optional equipment) Mudguards can be fitted on the trailer wheels by means of a sup- porting frame which is bolted to a mounting on the wheel axle. Mudguards are available for all wheel configurations. Stop wedges (optional equipment) Before driving, remove the stop wedges and place them in the stor- age brackets.

  • Page 25: Sprayer Setup

    4 - Sprayer setup General info Unloading the sprayer from the truck For the unloading of the sprayer, you need a crane. When unloading with a crane please observe the lifting points as shown on the pictu- re, and make sure that the straps or belts used for lifting are strong enough.

  • Page 26: Jack Up The Sprayer

    4 - Sprayer setup Jack up the sprayer When the sprayer needs wheel mounting, wheel changing, brake or wheel bearing changing etc. then jack up the sprayer under the axle as shown. DANGER! Be sure to place sprayer at level and firm ground to avoid sprayer falling down from the jack.

  • Page 27: Mechanical Connections

    4 - Sprayer setup Mechanical connections Drawbars - Mounting the drawbar extension The drawbar extension piece is inserted into the opening of the drawbar, fastened by two main bolts through the two holes (A) and secured by two linch pins. Following drawbar extensions are available.
  • Page 28 4 - Sprayer setup First installation of the transmission shaft is done in the following way: 1. Attach sprayer to tractor and set sprayer height in the position with shortest distance between the tractor and sprayer pump P.T.O. shafts. 2. Stop engine and remove ignition key. 3.

  • Page 29: Hose Package Support

    4 - Sprayer setup 8. To ensure long life of the transmission shaft, try to avoid working angles greater than 15°. Hose package support To prevent hoses and wiring from being damaged by the tractor wheels, P.T.O. shaft etc. all hoses, cables and wires are held by the hose bracket fitted to the sprayer platform.

  • Page 30: Fixed Drawbar

    4 - Sprayer setup Fixed drawbar Make sure the drawbar points straight ahead from its position on the trailer. If not, the two turnbuckles (A) can be adjusted till the drawbar is centred. STEERING drawbar transport lock (optional equipment) The transport lock is a safeguard that will keep the drawbar in a centred position in case of hydraulic leakage during transport on public roads.

  • Page 31: Hydraulic Systems

    4 - Sprayer setup Hydraulic systems General info Ensure that snap couplers are clean before connection! After having operated the boom and the system has been filled with oil, check tractor’s hydraulic oil level and top up if necessary. DANGER! Test of the hydraulic system should be done very cautiously. There may be air trapped in the system which can cause violent movements of the boom.

  • Page 32: Open Centre Hydraulics (Optional Equipment)

    Certain tractor models are able to use Load Sensing using an external sensing line (1/4” hose) directly from the tractor to the boom hydraulic block. If fitted, the LS outlet on the boom hydraulic block must be restricted using an 1/4” niple with an 0.7 mm orifice (Hardi part no. 146851).

  • Page 33: Electrical Connections

    4 - Sprayer setup Electrical connections Power supply Power requirement is 12V DC. Note polarity! The wires must have a cross sectional area of at least 4.0 mm to ensure a sufficient power supply. For the operating unit the tractor circuit should have an 8 Amp fuse.

  • Page 34: Road Safety Kit

    4 - Sprayer setup Road safety kit Connect plug for rear lights to the tractor’s 7-pin socket, and check function of rear lights, stop lights and direction indi- cators on both sides before driving. The wiring is in accordance with ISO 1724. See section in “Technical specifications”. Before transport on public roads the front warning boards with position lamps must be folded out (fitted in certain coun- tries only).

  • Page 35: Liquid System

    4 - Sprayer setup Liquid system Self-cleaning filter - Choice of restrictor It is important to have a large flow through the filter. This is achieved by choosing the restrictor size in relation to the liquid consumption of the spray boom. 4 restrictors are supplied. Use the green one with largest orifice (A) first.
