Chain Selection:- Tooth every station (TES): Designed for standard digging conditions in light to moderately compacted, sandy, loam soils and loosely packed gravelly soils. Typically good digging conditions.- Tooth every other station (TEOS): Designed to be the most productive in wet, sticky conditions such as wet clay, gumbo, etc. TEOS allows sticky soils to be discharged as it comes around the headshaft sprocket allowing the auger to pick it up and discharge spoil to the side of the trench.- Rock and frost chain 50/50 (50% R&F teeth/50% cup teeth): Gives highest production in frozen ground, highly compacted or rocky soils. Bullet shaped rock teeth break tougher soils and rock allowing the cup teeth to pick it up and clean the trench. Aggressive in tough conditions but not as productive in lighter normal conditions.- Shark tooth chain 70/30 (70% shark teeth/30% cup teeth): The 70/30 chain should be used in compacted soils, light frozen ground, baked hard clay, shale or rocky soils. Shark teeth will slice, break and relieve the tough soils allowing cup teeth to follow and clean the trench. Not as productive as TES chain in normal digging conditions.- Full shark tooth chain (100% shark teeth): Full shark tooth chain isrecommended for fracturable rock, shale, caliche or conditions with little or no loose soil. Will not efficiently clean the trench in sand, silt, and high moisture clay conditions.
