  • 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

    5 INITIAL INSPECTION AND SET-UP AERATOR ATTACHMENT __________________________________________________ CAUTION Always attach and remove the aerator on firm level ground. NOTE: If the tractor three-point hitch is a Category I and Category II type hitch, refer to the tractor manual to set the three-point hitch for Category II operation.

  • Page 25: Pto Shaft Guard

    Keep the tractor and the aerator guards in position and fastened. The aerator operates with a PTO speed between 400 and 540 rpm. Jacobsen recommends that the aerator is operated at 500 ± 10 rpm. Do not operate the aerator with a PTO speed higher than 540 RPM. Most tractors indicate a 540 rpm PTO speed on the tachometer.

  • Page 26: Tine Installation

    5 INITIAL INSPECTION AND SET-UP 5.10 TINE INSTALLATION_______________________________________________________ WARNING Before you install the tines, disengage the PTO, completely lift the aerator, engage the parking brake, stop the engine and remove the key. Put supports under the aerator frame. Lower the aerator onto the supports. To prevent injury, make sure the aerator frame sides are on the supports.

  • Page 27: Operation 6

    OPERATION 6 6Operation OPERATING PROCEDURE __________________________________________________ CAUTION To prevent injury, always wear safety glasses, leather work shoes or boots, a hard hat and ear protection. Always start the engine with the operator in the seat, never while next to the tractor. Never start the engine with persons near the aerator.

  • Page 28: To Stop And Park The Tractor

    6 OPERATION TO STOP AND PARK THE TRACTOR _________________________________________ To stop and park the tractor in normal conditions: Lift the aerator and disengage the PTO. Drive the tractor to a flat and level area to park. Remove your foot from the traction pedal and place gear selector in neutral. Lower the aerator to the ground.

  • Page 29: Aerating

    OPERATION 6 AERATING _______________________________________________________________ WARNING To prevent serious injuries, keep hands, feet and clothing away from aerator when the PTO is engaged. When you install, clean or remove the tines, wear gloves to prevent injury. Use a brush to remove dirt and debris. Tines edges may be extremely sharp and can cause serious injuries.

  • 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.

  • Page 31: Aerator Removal

    OPERATION 6 AERATOR REMOVAL ______________________________________________________ Remove the tines from the aerator. Lift the aerator and drive the tractor to an area to store the aerator. Stop the engine and remove the key. Adjust the two stands (G) on the front of the frame so aerator will rest on the stands and the roller. Completely extend the top link and disconnect the PTO shaft from the tractor.
