Instructions for installing the Grass Gator Rebel
Before Installing your Grass Gator, please check the kit to insure that all of the parts are included. In addition to the grass Gator replacement head the kit should contain 4 adapters, 6 nuts and 1 bolt. Check that your model is listed on the adapter chart below. If it isn't then verify that your machine is compatible (straight shaft trimmer, 30cc or more with a 1" male threaded shaft) and try adapter #5 first or call us at 1-800-210-9949.
Remove Original Head
In order to expose the threaded shaft needed to install the GrassGator head, you must remove the original head as a complete unit. Do not take it apart in pieces. If you do that, you'll leave the "spool shaft" on. The "spool shaft" is a long hollow cylinder threaded on the inside that works as an extender to accommodate the original head. If left on, the shaft will be too long and there will be too much play between the top of the shaft and the GrassGator head.
In order to remove the whole head as a complete unit you must lock the shaft before you can unscrew the original head. Most of the trimmers follow one of three styles:
Metal collar with a hole cut on top
Right on top of the original head there should be a metal collar with a hole cut on top. Use the tool that came with your trimmer and drop it down the hole. If yours didn't come with one you can use a nail, hex wrench or drill bit. Turn the head a few times until the locking tool aligns with the hole on the plate inside the collar. The tool will sink a little bit deeper and the head will offer some resistance once you try to turn it opposite to how it normally spins. Unscrew the original head as a complete unit. Remember, most straight shaft trimmers are on a reverse thread so try unscrewing the head to the LEFT first.
U shaped slit cut on the side of the plate
Right above the original head there should be a plate or metal collar with a hole or u-shaped slit cut on the side. If your deflector shield covers the plate, look for a hole on the deflector shield. Your trimmer may have come with a tool to lock the shaft (usually a metal rod). If yours didn't come with one then use a nail, screw driver or hex wrench instead. Insert whatever tool you are using into the slit and turn the head a few times. The tool will sink deeper locking the shaft. You'll notice that now the head will offer some resistance once you try to turn it opposite to how it normally spins. Unscrew the original head as a complete unit. Remember, most straight shaft trimmers are on a reverse thread so try unscrewing the head to the LEFT first.
"Nut" above the original head
Finally, some brands like Weedeater have what looks like a pot metal "nut" right on top of the original head that wraps around the handle of the trimmer. If that's the case with yours then hold the "nut" in place, don't let it move and then unscrew the original head off as a complete unit.
If:
- The original head of your trimmer is a fixed line then the GrassGator 12200 Rebel is not going to fit. You can exchange it for our model number 8010.
- If you unscrewed the original head as a complete unit and the shaft is longer than 2" then the GrassGator 12200 Rebel is not going to fit. You can exchange it for our model number 8010 .
Each of the adapters in the kit is marked with a number. Select the correct adapter using the chart here. If no adapter is listed and you confirmed compatibility then start with adapter #5 which is the shortest adapter.
Place the correct nut or bolt from the kit into the hexagon recess area of the adapter.
Locate the bottom of the GrassGator head. The bottom is the side with the hex shaped recessed hole. While the top side is the one with the screws.
Insert the adapter with the nut in it into the bottom of the Grass Gator head with the hexagon area of the adapter pointing towards you as you press it into place.
Slide the Grass Gator head onto the trimmer shaft with the nut or bolt facing away from the machine and screw the head onto the shaft.
Congratulations Your Grass Gator is now ready to use.
