The GrassGator Trims and Blows Model 8050 is a Multi-Tool head that works as a Pre-Cut line head or as an efficient blower. The 8050 takes 2 short lines (6" to 8" long depending on the cutting ratio of your trimmer) and 6 blower blades. You can use .095 or .105. It comes pre-loaded with GrassGator Shaped .105 trimmer line. There is no line to wind or spools to bump to advance more line.
To remove the old line simply pull from the inside part of the head.
The 8050 takes 2 pieces of line about 6" long. Originally it comes pre-loaded with .105 shaped trimmer line but it also takes .095 or .105. You can buy our pre-cut line model 8070 or you can cut your own.
Push the new line in from the outside making sure to leave about half inch sticking through the 2 small square holes on the inside part of the head.
The instructions on how to remove the head depends on how the head was installed originally.
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, alan 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. Remember, most straight shaft trimmers are on a reverse thread so try unscrewing the head to the LEFT first.
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 Allen wrench instead. Insert the whatever tool you are using into the slit and turn the head a few times. The tool will sink deeper and the head will offer some resistance once you try to turn it opposite to how it normally spins. Remember, most straight shaft trimmers are on a reverse thread so try unscrewing the head to the LEFT first.
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.
With the shaft locked in place unscrew the GrassGator head and remove it off the trimmer.
Loosen and remove the 4 screws and washers that hold the two halves of the head together (circled in red).
Do not open the head yet.
Hold both halves of the GrassGator head tight and flip the head upside down (domed side of the head facing up, the holes for the screws facing the ground) to avoid losing the cams and springs inside the head. Now you can remove the bottom cover of the head.
Before we go any further, there are some things you need to know about the blower blades (model 8060):
Remove the old blades by first pushing them an inch or so in the direction of the arrow printed on the blade until the back post clears the hole on the housing. Then, holding the blade by the back post, lift and pull to remove. Do the same thing for both blades. Do not discard the old blades yet. Save them for the next step.
As mentioned before, each pack of replacement blades (model 8060) comes with 2 sets of blower blades: one for right hand threaded trimmers and one for left hand threaded trimmers. The easiest way to determine which ones you need is by looking at the marks on old blades.
Now that you have selected the correct blades, it's time to install them:
Make sure that the blades, cams and springs are all in place. (See picture above).
Make sure the notches on the top part of the head align with the grooves on the bottom cover.
Keeping the head together, flip it over and replace the 4 screws and washers.
Screw the head back onto your trimmer
Your GrassGator is now ready to use!
