The main difference between 1/2 and 3/8 is the diameter of the steel wire. Different outer diameters of steel wires correspond to different diameters of steel wire ropes. 3/8 inch will be thinner and the overall spring will be softer, while 1/2 inch will be relatively hard.
It is recommended that you use the 3/4 inch heavy-duty machine. However, for tree roots, we don’t know how thick they are, so we cannot 100% guarantee whether they can be cleaned. It is recommended that you clean them multiple times.
