Changing blades on GrassGator Models 3600, 4600 and 4700

Lock the shaft

The instructions on how to remove the head depend on your trimmer and which installation method you followed to install the head

If:

You have a curved shaft, followed the curved shaft installation instructions, and/or you still have the original spool housing on your trimmer then hold the spool housing in place, don't let it move. That will lock the shaft and will let you unscrew the GrassGator head off.

You have a straight shaft and/or you don't have the original spool housing on your trimmer anymore then follow the same instructions as when you removed the original head.

With the shaft now locked, keep turning the GrassGator head to unscrew it. It will work as a wrench on the recessed nut or bolt. If it's been on the trimmer for a while and is hard to remove, spray some lubricant or solvent right where the recessed fastener is and let it soak for 30 minutes. That should help loosen the nut or bolt. Be careful not to force it or you'll end up rounding up the hex-shaped recessed hole which will ruin the GrassGator head.

If you need additional instructions on how to lock the shaft of your straight-shaft trimmer, check the straight shaft installation instructions:

Straight shaft installation

Pull the head apart

Re-install the head

Pull the head apart

The GrassGator head consists of two halves. One half has pins and the other one has holes to accommodate the pins. With the GrassGator head off your trimmer, pull on either half and it should come apart.

Install new blades

Re-install the head

Pull the head apart

Remove the old blades and install the new blades on the pins. Doesn't matter which side is facing up (flat or beveled) as long as all the blades are facing the same way.

Re-install the head

Press the halves together to close the head. Make sure all three pins are completely inside the holes. Screw the GrassGator head back into the shaft.
