High tensile (H-T or HT) fencing
If it is not possible to avoid cutting high tensile fencing, consider first de-tensioning it.
Cattle grids
Hydraulic spreaders or cutters may be required in order to create sufficient space in the cattle grid for the entangled animal to be manipulated or lifted out of the grid.
If the animal is entangled in a heavy-duty cattle grid, specialist rescue equipment may be required, such as a hot cutting torch that can cut through thick steel.
