Originally, the procedure was typically performed with modified wool-trimming metal shears, but now there are similar metal shears designed specifically for mulesing.
Special provisions for seismic load-resisting systems for all engineered wood structures requires consideration of diaphragm ratios, horizontal and vertical diaphragm shears, and connector/fastener values.
Attachments, such as breakers and compactors only need hydraulic flow in one direction, whereas thumbs, shears and grapples need two-direction hydraulic flow.
