Stens Tiller Tines aggressively dig through compacted soil and thick roots to prepare the ground for planting. Because of the nature of the work they do, tines are subject to quick wear and frequent breakage when digging into hard ground and striking rocks. While no tine can promise to completely eliminate these problems, Stens tiller tines are heat treated to slow down wear, preserve sharpness and reduce breakage. Quality tines that do more of the work reduce stress on tiller engines and make work easier for tiller operators.
