    • There is a shear to suit all suitable machines and purpose.  Our Muther Kutter shears are great for hedging and can be specified with rotation.  Not much in the UK grows straight so having a rotator on a shear is not a luxury it is almost essential.

            The Muther Kutter is nimble, compact and fast.  The cut capacity is upto 12 inch.  We will be honest here,  don't expect a 12 inch cut in hardwood! The Muther Kutter tree shear can be specified just as a shear with intergrated brackets (keeps weight down for small machines) , A bolt on headstock, or with either an AVS unbraked rotator or a Liebherr worm drive.

    The RSL "Lite" shear and "standard" shear are true beasts in their fields.  The capacity is from 12 inch to 20 inch cut.  The shears are designed so what you get in the jaw you cut regardless of wood hardness.   These shears differ from the fixed blade Muther Kutter as these shears grab the wood then cut.  This process which is delivered on one auxiliary circuit makes the Lite and Standard shear far safer to use compared to the fixed blade type of shear such as the Muther Kutter. 

    Rotation 

       We offer 3 types of rotation for the shears:

    • The Ram Pivots cost is limited rotation.  170 degrees.   That is 85 degrees either side of centre.  For the majority of applications this is more than enough.  The Ram Pivot is also priced exactly the same as a worm drive unit which makes it one tough outfit.   
    • Liebherr worm drive, 360 degree continuous rotation.  Maximum 2 RPM
    • Liebherr Slew drive  (like your diggers turntable).  Maximum 4 RPM and almost zero maintenance




    Protection Valves

    RSL's Tree Shears are an very effective and efficient method for reducing and felling trees and hedges. Our shears are designed to run at 200 bar max pressure.  This is important as your excavators auxiliary hydraulics are designed by the manufacturer to achieve approximately  200 bar. (we find results on excavators from 150-210 bar is normal).               
               We add the protection valves to make the shears plug and play.  Over the years we sent shears out with instructions for the owners to set their flows and pressures. Some did, most didn't!   The reason for this is in most cases the machines were not able to be set up.  Most modern machines flows can be set from the cab, the pressure cannot be changed though.  We added these valves and set them in our workshops on our testbed to the maximum values.  Your machine can put excess pressure to the shear but the valves will not let it through.  Hopefully with these valves and the onsite training we provide when you buy a Standard or Lite shear from RSL.   You will be able to relax and carry out one of the most fun jobs you can do with a digger!

    Flows and pressures

    Requirements for the RSL Shears are as follows:-

    The Muther Kutter

    1x double acting service upto 80lpm and MAX 200 bar for the shear

    1x double acting service upto 45lpm and MAX 320 bar for an unbraked rotator (if required)

    1x double acting service upto 25lpm and MAX 70 bar for a worm drive rotator (if required but don't really recommend this option on this shear)


    The Lite shear and standard shear from 12 inch cut to 16 inch cut

    1x double acting service upto 100lpm and MAX 200 bar for the shear and grab circuit.

    1x double acting service upto 25lpm and MAX 70 bar for the worm drive rotator (if required but we do recommend this)


    The standard shear 20 inch cut

    1x double acting service upto 120lpm and MAX 200 bar for the shear and grab circuit.

    1x double acting service upto 45lpm and MAX 70 bar for the worm drive rotator


    If you do not have the correct hydraulic services on your machine we can do valve packages that can be added to the shear to correct the requirements.  Please contact us for details.

    Onsite Training

    At RSL, we don't just sell you a shear.  Once the shear is ready it will be dispatched to you.  When you are ready Our MD will come along and check your machines pressures and set up flows for the rotation and grab.  He will then go through maintenance and training.  All this usually takes just a couple of hours.  Richard designed the shears and has been using them for many years, so can advise on any query.   Many people who have been through the training have mentioned how beneficial this has been.  From RSL's point we have also cut out 95% operator errors.  The training and shear protection valves have made an enormous difference to shear reliability.
