I have a hammer line on my machine, is that double acting?
Not necessarily, some machines don’t have double acting hydraulics as standard. Double acting is where you can pressurise both hydraulic lines going down your boom. On the machines which do have double acting, there will be a switch in the cab or a leaver on the hydraulic valve block, quite often accompanied with a drawing of a breaker or a grab to denote what is single acting or double acting.
Can I cut branches off without having a hydraulic tilt mechanism?
Yes, you can crowd the tree shear back so it is facing 90º, allowing you to cut the branch. You need to be facing the branch to get the right angle, and we advise you cut the branch in two or three stages, rather than cutting the branch in one go, which may cause damage to your machines hydraulic lines.
Does the TMK tree shear cut and hold the trees you are cutting?
Yes, the TMK tree shear cuts and holds the tree or vegetation, providing it is within the cutting diameters of the shears capability. When cutting with the TMK shears the operator needs to ensure that the pressure is kept on, until the tree is securely held in the V clamp of the shear.
Are the blades replaceable?
Yes, the blades are replaceable. If the fixed blade needs to be replaced, this can be done by cutting out the damaged section and re-welding a new blade in its place, in the same way as can be done with excavator buckets.
Is there a lot of maintenance on the shear?
No, the shear is a really basic concept, having only four grease points, either end of the ram and two on the main axel pin. The blade needs to be kept sharp. Any notches will need to be buffed out. The best way to do this is with a flap grinding disc, however be careful not to put to much heat into the blade as this can weaken the steel.
