JAK-300C is a new type of tree shear in our collection, where the cutting force is concentrated on the side of one clamping jaw.
This solution enables a lighter structure to allow smaller excavators to utilise this system, at a budget price.

This multipurpose tree shear model is the result of long-term product development and research. During the development, the design of the grapple has taken into account know-how based on real experience from our own solid experience in wood harvesting, as well as thoughts from real-life professional users. This tree shear has gone through a demanding testing process in fences and demanding conditions. With this, we can be sure of its functionality also with new end users in mind.

We use hardness-classified Hardox® steel in manufacturing! Domesticity and the use of top-quality materials also contribute to a structure and reliability that lasts even in the toughest situations and conditions.
