  • Page 9: Information About The Machine

    Information about the machine 1.4.1 Intended uses The RA-RAKE wheel rake has been designed exclusively for use in agriculture, for haymaking, swath formation and forage turning. The machine is towed by a tractor by means of a two point hitch attached to the lift bars. The working parts are driven by friction on the rear idler wheels which, as the tractor moves forward, rotate and allow the forage to be collected by the front idler wheels which start to rotate.
  • Page 10 1.4.2 Description The wheel rake works like a rake with continuous central delivery. Its main function in haymaking is to form and turn swaths. The machine has 6+6 (mod. 12+12 VS) or 7+7 (mod. 14+14 VS) double star wheels fitted with rake tines, mounted on two load-bearing frames, which are in turn supported by a central frame.

  • Page 29: 3- Transport On Public Roads

    TRANSPORT ON PUBLIC ROADS If you have to travel on a public thoroughfare, you must strictly comply with the Highway Code and pay particular attention to the choice of speed. Before entering a public thoroughfare from a non-asphalted or dirty area, you must thoroughly clean any residual mud from the tractor tyres.
  • Page 30 The weight of the machine alters the stability of the tractor-rake unit and affects the steering and braking capacity, especially on sloping or uneven roads. Therefore, drive at a moderate speed according to the road and weather conditions. In particular, bear in mind that the front axle must always be loaded with at least 20% of the overall weight of the tractor-rake unit.

  • Page 31: 4- Machine Operation

    MACHINE OPERATION Make sure that all machine parts are functioning properly during work. Most of the problems and breakdowns which may occur during use of the machine are caused by fastening components which come loose. Since all the mechanical parts and hydraulic connections need running in during the initial stage of the machine's life, it is essential to check the machine with utmost attention.

  • Page 32: Controls And Instruments

    Controls and instruments All controls are marked with special signs, which show their function and indicate their action and position with pictures (see Figure 13). Connect the RED “+” and “-” pipes to a double-acting distributor to operate the raking unit opening/closing system.

  • Page 33: 5- Hitching The Machine To The Tractor And Changing Set-Up

    HITCHING THE MACHINE TO THE TRACTOR AND CHANGING SET-UP Hitching the machine to the tractor The machine must be hitched to a tractor of suitable weight and power, in compliance with the legal requirements in force in the country of use. Before hitching the machine to a tractor, check the machine specifications, and compare them with the power, weight, etc.
  • Page 34 In order to hitch the tractor to the machine, the operator must reverse the tractor until the machine's hitch comes into line with the rear lifting bars (see Figure 14). Apply the tractor's parking brake, switch off the engine, remove the ignition key and climb down from the driver's seat.
