About TMK 400

vKnown as the Big Boy, the 400 is the largest and strongest in the TMK range. Due to it’s light weight it is suitable to cut down the smaller brush as well as the big logs. The strong capsular structure withstands the tensions of cutting down big trees, it was designed to cut the big trees of central Europe


The collector increases the productivity of the shear significantly. Collector works automatically with open-close motion all the way to the point where the bunch is dropped. When the shear is closed, the collector opens up to the other side of the trees, and when the shear is opened again, the collector first grabs the trees firmly in its grip. This way the trees stay all the time firmly in hand. Only when the bunch is dropped, one electric line is needed to let the bunch go from the grip. Collectors simple operation enables fast and comfortable working. Thanks to its high productivity, the collector is TMKs most popular attachment worldwide. NEW! Collector is now available also without electricity! Ask more from your local dealer, or directly from TMK.


Brackets are on bolt-on extra plates, this makes it possible to use the shear with multiple machines.


With the splitting blade you can finalize the trees cut with the shear, without unnecessary hassle. The splitting blade attaches to the side of the shear with three bolts. Splitting blade works best with the bolt-on-blade models, when you can also load or move the trees with the same shear.


With the heel you get more support and reliability to the shear when moving in any terrain. You can safely take support with it, no matter the size of the machine. The heel attaches to the backside of the shear with bolts offering good support point when moving with the machine.


TMK 400 can be equipped with different cylinder options. 1. Normal main cylinder, recommended pressure 280-300 Bars. 2. TMK Turbo is patented telescopic cylinder, where the smaller cylinder works always first, keeping the motion fast. When the smaller cylinder runs out of power, the bigger cylinder starts working automatically. This way we get really fast motion without sacrificing the strength at all. TMK Turbos’ recommended pressure is 200-220 Bars. TMK Turbo is excellent choices when working with tilt rotators, when the reduced pressure doesn’t affect the maximum cutting capability. TMK Turbo grows your work efficiency up to 15%!


Do you want to cut over hanging branches? Or just operate in unlevel terrain and want to leave the stump as low as possible? Or need a little bit more agility to stack the trees neatly? The tilting unit is just the feature for you. The tilt fits both TMK 300 and TMK 400 and is robust enough to withstand the challenges of hard work in the forest. Tilting unit tilts 90° both ways, so it’s a great tool to cut down over hanging branches, but it also gives more agility to operating the shear and moving the cut down timber. Tilt can be controlled with a separate hydraulic line, or with the same line as the shear with the help of a 6/2 electric valve.
