Modifying the PTO Shaft-if required
The PTO Shaft included with your new MIGHTY MAC Chipper may be too
long for your tractor. To shorten the Driveshaft, proceed as follows:
Tools and Supplies Needed:
• Hacksaw
• Bench Vise
• Tape Measure
• File
• General purpose Lithium Grease
• Philips Head Screw Driver
1. Separate the PTO Shaft Halves by pulling them apart.
2. Remove the 3 Philips Screws from the PTO shaft Halves (Figure
16) . Remove the PTO Guard.
3. Measure and cut the ends of both Guards the required amount (Figure
17).
NOTE: If you put the Guards in a vise to hold them, be careful not to
clamp it too tight because it could crack the plastic.
4. Measure and cut each Shaft Tubes to the required length using the
hacksaw
(Figure 18).
5. File or sand any burrs from the Shaft ends.
6. Grease both Shaft Tubes and under the Bearing Rings of each Shaft
(Figure 19).
7. Re-install the PTO Guard and tighten the 3- Philips Screws.
8. Slide the two PTO Shaft Halves together.
NOTE: When inserting one half of the PTO Shaft to the other you must line
up the splines correctly (two pointed splines and one flat spline).
