Dymax Tree Shear Range

Why Buy a Tree Shear Attachment?

Simply,  why use chainsaws if you can do the job cheaper, quicker and safer working from the warm and comfortable cab of a machine in almost all weather conditions?

Tree Shears have become the most cost-effective and safest way to fell trees since Practicality Brown Ltd introduced them to the UK in 2005.

Why buy a Dymax Tree Shear and not another make like Westec, Tigacut, TKM, etc?

Dymax Tree Shears are designed for felling proper trees ranging from 3” to 20” diameter, and they are the strongest and most robust tree shear in manufacture.

Any other tree shear with only one shear cylinder and one blade is relying on that cylinder having the torque to push that blade the whole way through the trunk, which on hardwood like Ash takes some doing, and invariably can end up suffering from metal fatigue and downtime before long.

Dymax Tree Shears are fitted with two flat blades and two high torque large cylinders which cut through hardwood with ease, no chomping required!

Lighter weight Grapple Shears are cheap and useful for trimming farm hedgerows and felling small trees, but are not designed for safely holding or cutting tall trees on a windy day! 

Having taken note of the competition and customer feedback, Dymax have now added a heavy-duty well-engineered 180-degree rotation option to the range; Its arrived at last!

Like ‘Horses for Courses’, its ‘Shears for Trees’!

Here are the details of the full Dymax Tree Shear range for 2020:

Grapple Tree Shears

These are the most popular models that grip, shear and control trees until released

Dymax Grapple Shears are the most reliable, most ruggedly built heavy duty tree shear in the world.

Ideal for site development, tree clearance, utility maintenance, fire breaks, heathland restoration, forest thinning and removal of diseased trees caused from such infestations as the Pine Shoot Beetle, Phytophthora and Ash Dieback.

Dymax Tree Shears are two bladed Grapple Tree Shears offering twice the cutting strength of single bladed tree shears.  Dymax Tree Shears cut the same diameter hardwood as softwood, at the same speed in one cut and are therefore the best for Ash Dieback Clearance.

Grapple arms operate in conjunction with the shear arms through the use of a sequence valve. Dymax Tree Shears are easy to switch between different excavators as they just need a shear circuit and a rotation circuit( for rotation models) which most late excavators have as standard fitment.

Excavator/Skid Steer FG Models:

Dymax FG Grapple Shears are an excellent long lasting entry level tree shear attachment for occasional or seasonal use contractors, and ideal for the normal site clearance application.

The 14” models feature Replaceable Dymax 3/4” (19mm) AR400 cutting knives and Two powerful 5” (13cm) hydraulic cylinders.
