The Various Types of Weed Eater Heads

The Bump Feed

There are several types of weed eater heads on the market, but just as you will guess, they almost function in the same way. Among the most common is the bump feed system, which gets its name from the need to bump or tap the tool’s bottom rightly on the ground.

Most gardeners actually prefer the bump feed over any other type – they are convenient and easy to use. However, the constant bumping eventually takes a toll on the head, eventually needing replacement.

The Fixed Head

As opposed to winding an entire line length around a spool, this system needs the loading of individual lengths. This makes your task easier – no need to spend a significant amount of time winding and this explains why it is favorable for commercial weed eaters.

Fixed heads are sufficiently thick and rugged, and you don’t need to replace them continually – it saves you time and money. It is also ideal for people that consider line winding too much of a hassle.

Automatic Feed

This is another variety common among current machines. Just like the bump feed, the automatic feed utilizes a spooling motor, but unlike its counterpart, the process is automated – the name even tells you that much.

The automatic feed heads are easy to use and make your task of subduing the brush around the homestead quicker. The only shortcoming with this variety is that replacement is quite expensive.

Factors to Consider when Selecting a Weed Eater Head

The weed eater head is one of the most important since this is where you place the line that whacks the weed – without the head, there would be no weed whacking.

However, surface debris, little stones, and metallic objects are likely to come in the way as the machine works. This only means that you will need to replace it eventually – it’s a certainty.

But you can reduce the costs associated with replacement by purchasing the best weed eater head you can get.

  • Power: with all the fuss about reducing greenhouse gases and fast-paced technology characterizing contemporary life, electric trimmers are thus quite common – their convenience and ease of use are other important factors behind their success. Despite their eco-friendliness – we are not saying it is a bad thing – they cannot match the gas-powered trimmer heads regarding power and durability. The gas trimmers heads and machines are resilient and will go a long way in trimming the weed, giving you a significant amount of service – after all, reliability is what everyone looks for.
  • Size: the size of the trimmer head you choose is based on the size of your yard. The bigger your yard is, the bigger the machine you’ll need – as simple as that! It would not make sense to go for a smaller one, and your yard is expansive – it would mean spending a lot of time on it to cover every ground surface.
  • Smaller heads may appear cheaper and more durable, but that’s not the case. Their small size means that they may not be in a position to overcome the obstacles along the way. Bigger heads are, thus, more durable, besides making brush clearing easy.
  • Compatibility: you can never choose the wrong trimmer head for your machine regardless of its high-end features – where would you use it? Typically, the specifications and features will tell you whether it’s the right head for your weed eater.
  • The Type: we have mentioned the various types of trimmer heads available on the market. Ideally, you should go with the trimmer that effectively serves your needs – there’s usually no need to go with the flow and choose a trimmer like a bump head only to put it away since it is hard to master its usage.
  • The Cost: when it comes to such accessories as trimmer heads, don’t go so much with the cheap, or you will regret your purchase. Best is not always cheap – keep that in mind.


Having a decent weed eater helps control weeds and grass on your lawn. With that, you need a good head to compliment it. All the listed products are a feature for a good reason – they are among the best. However, Shindaiwa 78890-30000 Feed Trimmer Head steals our top spot for a pretty good reason.

The machine features improved speeds, and its compatibility levels with most of the major blades are something notable. Loading and use is a breeze, and the only thing you might regret is not finding it earlier.
