  • Page 33: First Use

    FIRST USE It is recommended to do the procedures in this chapter together with your authorized Lely dealer. Adjust the Length of the PTO Shaft To avoid damage to or reduction of the lifetime of the PTO shaft, the PTO shaft must not be extended over its maximum permissible length.

  • Page 34: Adjust The Rake During First Use

    Deburr and clean the safety guard tubes and the PTO shaft halves. Slide the two PTO shaft halves into each other. Slide the inner and outer safety guard tube over the PTO shaft. Connect the PTO shaft to the rake. Figure 10.

  • Page 35: Operating Instructions

    OPERATING INSTRUCTIONS Ensure no-one is near the rake at the moment the PTO is engaged. If anyone comes near the rake immediately stop the tractor and disengage the PTO. Switch off the tractor engine and remove the key before leaving the tractor cabin.
  • Page 36 Adjust the tractor’s three-point hitch arms to an equal height. Fit the lower arms of the three-point hitch to the linkage pins (4) (cat II) of the headstock (1) (see figure 12 on page 6-3). Attach the top link of the tractor to the headstock of the rake with a top link pin (2) (cat II).

Put the rake in the working position as follows: Pull out the locking pin, move it to the top position and release it to unlock the steering device.

  • Page 41: Lift The Rake To Turn On Headlands

    Slide the swath curtain outwards and secure it with the locking pin (see figure 24 on page 7-2). Lift the Rake to turn on Headlands Never drive the rake through the crop while the rotor is on the ground and is not rotating. This may damage the tines and the tine arms. If the rake is lifted in a turn, it will swing to the central position automatically.

    Start raking Make sure no people are near the rake at the moment the PTO is engaged. Keep safe distance from people. If a person comes near the rake, stop the tractor and disengage the PTO. Switch off the tractor engine and remove the key before leaving the tractor cabin.

  • Page 46: Take The Rake Out Of Operation

    Move the three-point hitch of the tractor upwards to lift the rake from the ground. Disengage the PTO. Wait for all moving parts to stop. When leaving the field: Put the rake into the transport position (see page 6-3). Take the Rake out of Operation To work safely it is important to take the rake out of operation before doing maintenance, troubleshooting, making adjustments or before certain operations.
