How to re-load the GrassGator Bump & Feed model 3630

Open the Bump & Feed head

There are tabs on the side of the GrassGator head. Push one of the tabs towards the head to open it.

Remove the spool

Once the head is open, remove the spool from the spool housing. Unwind any leftover line and remove it from the spool.

Get the new line ready

Cut the piece of line you will be loading into the GrassGator head. The GrassGator Extra Heavy Duty Bump & Feed head (model 3630) can hold up to 10ft of .105 line or up to 14ft of .095. Fold the line in half.

Determine which way to load the spool

The 3630 spool has 3 concentric rings. If you look between the rings you should see two things: two holes or eyelets on the body of the spool one on top of the other (red arrows) and a u shaped slit on the edge of the middle (2nd) ring (yellow arrow). The line will go through the holes on the body of the spool and the center loop will be held in place by the U-shaped slit on the center ring but first you need to determine which way you should install the line.

• If your trimmer has a right hand threaded shaft (most curved shafts do) then you will setup the line this way:

• If your trimmer has a left hand threaded shaft (most straight shafts do) then you will setup the line this way:

• If you don't know which one you have, try unscrewing the GrassGator head off your trimmer. If it follows the lefty-loosey / righty-tighty rule then it's a right hand threaded shaft. If the housing unscrews to the right then it's a left hand threaded shaft.
• There are 2 sets of eyelets opposite to each other to accommodate a left hand or right hand setup.

Re-load the spool

Take the new piece of line and insert one end in each of the holes on the body of the spool following the setup determined on step 4. Pull the line evenly and snap the center loop in the U shaped slit on the middle ring. Wind the line around the spool in the direction indicated by the arrows on the spool: left hand thread is winded clockwise while the right hand thread should be winded counter-clockwise. Keep each section of the line on its own half of the spool (top or bottom). Leave about 6" of line loose.
