  • Page 16 65 Series Rotary Tiller DRIVELINE DIMENSION – cont’d. Pull the driveline apart and cut 1/2 of the dimension determined in step 5 from each end. Add another ½ inch (12MM) to each cut off segment. Be sure to use a hacksaw to cut 1/2 from each end of the separated shaft. Cut both the plastic tube and the metal cores.

  • Page 17: Attaching/Unhooking

Be sure the tractor 3 point hitch is in the Category 1 configuration and the lift arms are in the non-sway configuration (See tractor manual).
  • Page 18 65 Series Rotary Tiller ATTACHING/UNHOOKING – cont’d. Attach the PTO driveline: Check that the driveline telescopes easily and that the shield rotates freely. CAUTION: Be sure that the driveline does not bottom out when going through its working angles.

  • Page 19: Field Operation

    65 Series Rotary Tiller FIELD OPERATION Buhler Farm King 65 Series Rotary Tillers are designed with the inherent flexibility of operating well in almost any kind of soil and terrain conditions. However, the operator has the responsibility of being familiar with all operating and safety procedures and following them.
  • Page 20 65 Series Rotary Tiller FIELD OPERATION - cont'd. Offset: The Category Pin Brackets can be moved 3 to 4 inches along the Deck Assembly to either side of center if required. Center the machine for normal operation. Offset if the tire tracks are wider than the machine or when tilling around trees, bushes or other areas.
  • Page 21 65 Series Rotary Tiller FIELD OPERATION - cont'd. Operating hints: Determine the moisture content of the soil before starting. Soil that is too wet will "ball-up" in the rotor blades making tilling impossible. Sandy soils normally can be worked better than heavy clay or loam soils. It is the responsibility of the operator to determine the soil type and moisture content before starting.
