But among them, the ECHO SRM 280S and the ECHO SRM 280T stand out the most. And it is because of their qualities and performances.

The Differences Between SRM 280S And SRM 280T

There are not many differences between the SRM 280S and the SRM 280T models. So you may not find them out in the first place. But these few differences may affect the main work of trimming.

1. Special Feature

The SRM 280S and the SRM 280T may look very similar, but their work differs a little. They have different features and specialties. The SRM 280S is famous for its steel drive shaft, and the SRM 280T is for its high-torque function.

Since the drive shaft of the SRM 280S is solid steel, it provides a less weight to the trimmer. And so, the acceleration increases and also it is easy to carry.

But, the SRM 280T has more torque. It is different from other SRM 280 trimmer, for it provides 50% more torque. SRM 280T also gives more grunt to the sound while trimming the grass.

2. Cutting Head

The most significant difference between SRM 280S and SRM 280T is in their cutting head.

SRM 280S have an ECHOmatic Pro trimmer head, where SRM 280T comes with the ECHOmatic one. Both the ECHOmatic cutting heads are best for home lawn owners, commercial gardeners, and experts.

These trimmer heads are almost similar but still have differences in some parts.

The ECHOmatic cutting head comes with some extra parts where the ECHOmatic Pro head is simple in structure.

The additional elements that the ECHOmatic trimmer head has are:

  • Two eyelets,
  • Three bolts, and
  • Three studs.

But the ECHOmatic Pro reduces these parts and has a smooth structure. And so, the attachments of the cutting head differ a little in both trimmers.

Thus, the installation of the cutting head is easier in SRM 280S than in SRM 280T.

3. Drive Shaft

The main difference between the SRM 280S and SRM 280T is their drive shaft.

As we have mentioned before, the drive shaft of the SRM 280S is of steel. And the features of the shaft are:

  • Steel body
  • Hollow shaft
  • 00 mm in diameter
  • Lightweight
  • Come with a self-lubricating bearing

The body is solid and rigid. So it gives more acceleration when you are trimming the grass.

On the other hand, the drive shaft of the SRM 280T is of cable-layers. Its features are:

  • Four-layer cable body
  • Flexible
  • 35 mm in diameter
  • Comparatively heavyweight

Since the material of the drive shaft is cable-layers, it has more flexibility than that of SRM 280S.

4. Additional Accessories

We all love accessories. And both the SRM 280S and the SRM 280T have many of them. But both of the trimmers may come with some different tools or equipment.

Some extra accessories of SRM 280S:

  • Universal Blade Kit
  • U-Handle Blade Kit
  • Tiller/Cultivator

Some additional tools of SRM 280T:

  • Speed-Feed 375 Trimmer Head

Best Choice For you

After reading the differences above, you may have a good idea about both the SRM 280S and the SRM 280T trimmers. Now, it’s on you to choose what is best for your lawn.

But we can give you some suggestions to select a suitable trimmer.

The steel drive reduces weight and provides more speed. And so the SRM 280S has more acceleration.

Where the SRM 280T has more torque. But to increase the torque, it decreases the head speed.

So if you want high speed, you should go for the SRM 280S. And if you want more torque, you can buy the SRM 280T.

The SRM 280S drive has a steel body. So it is more durable.

The cable drive shaft of the SRM 280T is not as durable as that of SRM 280S. But if you maintain it properly, it may last for a long time.

And so, if you want your trimmer to be long-lasting, you should opt for the SRM 280S.

Since the drive shaft of the SRM 280S is steel, it is sufficiently rigid. So the vibration while trimming is close to none.

On the other hand, the flex drive of the SRM 280T may vibrate now and then. And many people may not like it.

Now you can look for all these factors to choose between SRM 280S and SRM 280T.
