Cuts up to 250 mm
TMK 250 has been designed to cut all the way up to 250 mm (9,8") trees.
One grapple design
TMK Tree Shears were the first guillotines in the market to utilize only one moving grapple arm. This provides superior strength for the frame and better alignment for the blade. It also allows us to make our shears lighter and easier to maintain than the two grapple equivalents.

Hanging Tilt
TMK 250's Hanging Tilt allows it to be used on forest machines and tractor cranes. It features a "pocket" for the trees to sit in at the top of the linkage and it has a center of gravity that is optimized for cutting and handling forces.
Optimized grapple & blade geometry
The grapple and the blade on the TMK 250 are a little bit different from the rest of the shears.
The bottom piece of the grapple is curved more to allow better cutting action when the shear is hanging and it isn't possible to push with the machine. The blade features a deeper "pocket" for the trees to sit in so it doesn't slide from the optimal cutting position.

Clean cuts with Brushgrapple
It allows “scissor”-like cutting, that provides much cleaner cutting results for small shrubs instead of twisting and ripping them from the ground with roots.
Modular design
Some say our Tree Shears can be assembled like Lego’s; you can build them up piece by piece from the basic shear to a professional piece of kit that can accumulate, de-branch, extend and rotate.
)
Optional attachments
Our powerful attachments will make your work more efficient. All TMK 300 attachments are designed for easy and simple retrofitting.
Coupler options
Many boltable rotators fit directly to top of the TMK Hanging Tilt.
For quick connect rotators we have several different connection adapters available.

Cutting cylinder options
The versatile cylinder options for main cylinders of the TMK Tree Shear allow you to adapt the shear to your existing machine, both in terms of cutting power and operating speed. Because of various cylinder options, the shear can be connected to just about any machine.

Control method options
All that the base model TMK Tree Shear needs to function is one double-acting hydraulic circuit. Any attachments can be controlled with our innovative valves & kits, up to 4 functions from just one double acting hydraulic line!
By default, the electrical wiring kit or pressure-control valving is included in the price of the attachment. The pressure-control valving is plug and play, and the electrical control version can be upgraded to plug and play setup with the additional relay box which includes button strip and plug for the 12V outlet, or by fully upgrading to the wireless radio control with TMK Wireless Kit. The TMK Wireless kit is extremely useful in certain situations, such as using the product with a tiltrotator, or between multiple different machines.
It is also possible to use separate hydraulic lines for any of the different functions, if you wish to do so.

It’s a simple product which works. We can cut and hold the material safely and lie it down windrow so our chipper can come through and clear it easily.
