  • Page 22: Pto Shaft Length Adjustment

    5 INITIAL INSPECTION AND SET-UP PTO SHAFT LENGTH ADJUSTMENT__________________________________________ The PTO shaft can be longer than needed for your tractor. If necessary, decrease the PTO shaft to the correct length. • Always cut equal amounts from the PTO shaft tubes and the cover. Make sure that when cut the tubes overlap by at least 1/3 of the tube length in the maximum extended position.

  • Page 23: Pto Shaft

    INITIAL INSPECTION AND SET-UP 5 10. Assemble cover shields onto appropriate PTO halves. Cut the safety shields so there is 1 in. (25.4 mm) of PTO shaft extending past the end of the shield. 11. Assemble the PTO shaft. Replace any decals that were damaged by cutting PTO tubes and shields. 12.

  • Page 24: Aerator Attachment

  • Page 30: Hole Spacing

    6 OPERATION HOLE SPACING ___________________________________________________________ The front to rear hole spacing is a function of tractor gearing. Some tractors will allow as low as 1 in. (25 mm) spacing. Spacing greater than 8 in. (203 mm) is not recommended in order to achieve proper aeration/ cultivation. Because forward travel speeds and PTO speeds are both directly tied to engine RPM, hole spacing should remain constant for each gear, regardless of engine speed.
