Attaching the Mower to the Tractor

TO PREVENT SERIOUS INJURY

OR DEATH. Back the tractor up to the mower so that the lower draft arms are in alignment with the mower lift pins. Stop the engine, lock the brakes, place the tractor in park, and remove the key from the ignition.

1. Read the tractor manufacturer’s di-rections for P.T.O. connections to the tractor.

2. Shorten or remove the tractor draw-bar so it will not interfere with the up and down movement of the mower.

3. Connect the tractor and stabilizer bars to the lower lift pins. Adjust the top link so it will connect to the top holes in the A-Frame or into the holes in the floating top link.

4. Slide yoke onto the tractor P.T.O. shaft.

5. Move yoke back and forth until lock-ing pin has engaged on the P.T.O. shaft groove. When attaching the driveline yoke to the tractor P.T.O. shaft; the spring activated locking pin must seat properly in the tractor P.T.O. shaft groove.

6. Secure the P.T.O. shaft guard with the chains connected to the main unit.

7. Use stabilizer bars or sway blocks appropriate to the tractor to prevent side sway of the mower.

OPERATING INSTRUCTIONSRead the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this manual including all text under subheadings therein before set up or use of this product.

1. The gearbox of the Mower must be filled with a SAE 90 EP oil before first use of the Mower.

2. Before operating the Mower, put on ANSI-approved safety goggles and other safety gear. Safety goggles and other safety gear are sold sepa-rately.

3. Attach the Mower to the tractor.

4. Raise the Mower and brace it up securely before adjusting the wheel for height of grass desired. Always brace the Mower when it is raised; hydraulic systems can fail causing the mower to fall onto the operator.

5. Start the tractor and allow it to warm up and achieve idle speed.

6. To transport the Mower, disengage the P.T.O. and raise it to full transport height before moving to the mowing area.

7. Lower the Mower. Reduce engine speed and engage the tractor P.T.O. Gradually increase the engine speed to develop full P.T.O. speed of 540 RPM.

8. Enter the area to be cut with the cutter operating at P.T.O. speed. If it becomes necessary to regulate engine speed during operation do so gradually.


9. This Mower is only recommended for light duty use on level lawns. Cutting speed will depend upon the height, type, and density of the grass to be cut. Tall or thick grass should be cut at low speed, while short, thin grass can be cut faster. Grass should be cut when dry; wet grass will stick to the Mower and clog it up.

10. If the mower contacts a hidden ob-struction, immediately stop operation. Raise the mower, turn off the tractor, and disconnect the drive shaft. Se-cure the mower in the upright posi-tion. Verify that the mower is not damaged before continuing.

IN ORDER TO AVOID PERSONAL INJURY OR PROPERTY DAMAGE. When attempting to stop a tractor which does not have a live P.T.O, the momentum created by the blades of a mower can cause the tractor to be pushed forward. Do not operate this mower unless the tractor has a live or independent P.T.O.

11. When finished, move the Mower to the intended storage area, and allow the P.T.O. to rotate to a stop before getting off the tractor.

12. To prevent accidents, disconnect the mower from the tractor after use. Clean, then store the appliance in-doors out of children’s reach.
