Factors To Consider When Installing Universal Trimmer Head
Switching out your trimmer’s cutting head for a Universal Trimmer Head can take your lawn care to the next level. You’ll be trimming your lawn in no time! Before getting started, there are a few factors you should consider.
The Shape and Size of Your Trimmer Head
The shape and size of your trimmer head are significant factors to consider when looking for a replacement. Traditionally, the shape of the trimmer head would indicate the type of line to use on the spool.

The round trimmer head is typically used with monofilament or twisted lines, while square trimmer heads work great with serrated lines.
Ultimately, the size of the trimmer head will also affect your installation. The trimmer head should fit comfortably on your tool.

The price of a trimmer head can vary depending on its features and brand. You should buy one that fits within your budget. However, you should not go for one with cheap quality just because it is cheap. You will end up replacing them in a few days.
Compatibility With Your Trimmer

The Universal Trimmer Head comes in 1″ and 1-1/8″. Measure the diameter of your shaft to know which one to buy.

- Check if your shaft is solid or split.

How To Install a Universal Trimmer Head
Installing the Universal Trimmer Head is a simple task that should take only a few minutes to complete. However, the key to a successful installation is ensuring you use the correct shaft size and that the tip will fit comfortably to your trimmer line. Here is how to install your universal trimmer head.
1. Unpack the Trimmer Head
Before installing your universal trimmer head, you must first remove it from the packaging and check that all its parts are present.
If any parts are missing, contact the company’s customer service team immediately so that they can send you a replacement free of charge.
2. Remove the Old Trimmer Head
Remove the bolt that holds the old trimmer head to the shaft. As a locking nut, this bolt is designed to be difficult to loosen. To loosen it, use a screwdriver or other tool with a flat edge to hold the head in place while turning the lock nut with your wrench.
Once you’ve loosened it enough, continue turning by hand until you can remove it altogether.
Remove the old trimmer head from the shaft of your trimmer. It may pull off easily at this point; however, if your line has been cut off too short (shorter than 1″), it may catch on something inside your machine and need some coaxing out with a tool such as pliers or wire cutters.

3. Install the Universal Trimmer Head on the Shaft of Your Machine
After you have removed the old head, place the universal trimmer on the shaft of your machine. Use the instructions that came with the head to find the correct position of the shaft. Foremost, you will need to use a screwdriver to loosen the trimmer head’s knob.
After loosening your trimmer head’s knob:
- Pull both ends of your string out of one side until they are taut and parallel.
- Find an empty hole on one side and push a fortune into it until it is through to come out another open hole.
- Repeat this step with both ends and tie the two ends together again, just as before.
Then, tie a knot at one end of each string, leaving enough room between them to easily pull apart when installing or replacing the strings later on.
4. Follow Instructions for Tightening and Adjusting the Knob and String
Next, tighten the knob that holds the head-on. Turning it clockwise will tighten the head more firmly, while counterclockwise will loosen it. So tighten the knob by turning it clockwise until it is firm and secure enough to withstand any force when trimming.
Additionally, the string should extend to about 1/4 inch long, but not to the extent that your trimmer may get stuck or tangled in grasses or weeds. In essence, once you’ve tightened the knob just right, try spinning the string around a few times to see if it’s an even length.
If some parts are longer than others, take them off and adjust until each part is equal. However, don’t over-tighten your universal trimmer head, as it can damage the whole tool.
No matter what kind of trimmer head you’re working with—brush cutter, line trimmer, mower, brush hog or other—the installation process is the same. The benefit of using a universal trimmer head like the Husqvarna 537388101 Universal is much easier to use.
It’s compatible with almost any line trimmer on the market; all you need to do is adjust it to fit your needs. And if you already have a traditional trimmer head installed, there are manual tools that you can use to change its mounting position.
