Features

STIHL 4-MIX® engine
You can always rely on STIHL to keep setting new benchmarks this time with 4-stroke mixed lubrication technology. unlike a 2-stroke, offers the benefits without the compromises of 4-stroke power.  The STIHL 4-MIX® engine technology provides fast acceleration, more power, added torque, lower noise, reduced emissions and increased fuel efficiency.

Air filter with long service life
The easily accessible paper filter with a long service life means it can go for long intervals without  needing to be changed.

Manual fuel pump (Purger)
A small fuel pump delivers fuel to the carburettor at the touch of a button. This reduces the number of starting strokes required following extended breaks in operations.

Bike handle
When used in conjunction with a harness, the bike handle enables a smooth mowing action. The bike handle allows the machine to be easily guided, making it ideal for working on large areas and thus reducing fatigue.

Anti-vibration system
Intense vibration at the handles of power tools can lead to long-term effects on blood vessels in the hands and arms. STIHL has therefore developed an effective anti-vibration system whereby the oscillations from the machine’s engine are dampened which significantly reduces vibrations at the handles.

Multi-function handle
All the engine and speed controls are easily accessible and at your finger tips.

Tool-free handle adjustment
The handle bar can be easily adjusted to suit the users working position via the tool-free handle adjustment clamp.

ADVANCE Universal Harness
Soft padding makes work more comfortable during longer jobs.

Stop switch
The multi-function control handle features a stop switch which automatically reverts back to the start position for a quicker, simple restart.

    Good service from Radmore and Tucker. Early days using the brushcutter but very happy with the purchase thus far.

  2. PDB (verified owner)

    Early days but so far I’m very pleased with brushcutter and service from R&T

  3. Neil Sammons (verified owner)

    Used for three hours solid great tool very well balanced and the 4mix engine is a powerful motor great on fuel and surprisingly quiet.

  4. Heather Hawley (verified owner)

    Very efficient service from RT. Products came the next day, all assembled and fuel in the tank.
    This brushcutter is very easy to use. Being a short, smallish female, sometimes these sorts of machinary can be heavy to use. However, due to the excellent harness supplied, the cutter can be well balanced making it lightweight and easy to use. The hip pad is a great idea. Starts easily. It will be used by a few people within our village hall committee and I am confident it will suit all of us and will be a great help at keeping the field ground maintained.

    Brush-cutter arrived as agreed and well protected. Very pleased with the quality of the materials. It is fairly easy to start and runs very smoothly; the usual 2 stroke issues of getting a cold motor to kick in apply but I’ve owned 3 and this was the easiest to start. There is a minor issue in that the strimmer starts as soon as the motor runs and if I had the steel brush cutter attachment attached and close to the ground, could cause an injury; carb prob needs resetting. The accessories that arrived with the strimmer are excellent; again, good quality stuff that is well worth the money as they will last. The last harness I had from another supplier lasted less than 3 months because of bad workmanship! The full bar is a pain to store because it is so long but I think you will be less likely to damage the drive as there is a lot of torque and this is a weak point in most, it gives good reach though and the balance is excellent. Really happy!

    Stihl fs 91
    Excellent service from R & T. Out of the box a couple of pulls and away. Used 3 or 4 times for a minimum of 4 hours and runs great, plenty of power. Good size fuel tank so less downtime refueling. Harness is fantastic, so comfortable hardly know you have the strimmer attached to it. Should last a good few years with regular servicing. Early days but very happy with purchase so far.
