Tuber bruising occurs when individual tubers receive mechanical impact exceeding the potato cell wall&#8217;s elastic limit \u2014 the point at which cellular damage occurs, producing the brown discolouration beneath the skin that reduces Grade 1 classification and accelerates storage deterioration. Stone-cleared fields reduce bruising through three mechanisms:<\/p>\n<div style=\"display: flex; flex-wrap: wrap; gap: 14px; margin: 14px 0 28px 0;\">\n<div style=\"flex: 1 1 200px; background: #fff; border: 1px solid #e0e0e0; border-top: 4px solid #2d5f2d; padding: 16px 18px; border-radius: 0 0 6px 6px; box-sizing: border-box;\">\n<p style=\"font-weight: bold; color: #2d5f2d; margin: 0 0 6px 0;\">Mechanism 1: No stone-to-tuber contact<\/p>\n<p style=\"margin: 0; color: #555; font-size: clamp(12px,1.3vw+8px,14px);\">On stone-cleared fields, the EP-AWB-1600 share lifts soil and tubers without stone fragments entering the soil stream. No hard stone surfaces in the lifted material means no high-energy tuber-to-stone impacts in the web separator zone. This eliminates the most severe bruising category \u2014 the direct impact bruise from stone contact that produces large, deep brown areas affecting significant proportions of the tuber surface.<\/p>\n<\/div>\n<div style=\"flex: 1 1 200px; background: #fff; border: 1px solid #e0e0e0; border-top: 4px solid #2d5f2d; padding: 16px 18px; border-radius: 0 0 6px 6px; box-sizing: border-box;\">\n<p style=\"font-weight: bold; color: #2d5f2d; margin: 0 0 6px 0;\">Mechanism 2: Consistent share travel<\/p>\n<p style=\"margin: 0; color: #555; font-size: clamp(12px,1.3vw+8px,14px);\">Stone deflection of the share on un-cleared fields produces sudden depth changes and brief deceleration events that throw tubers against the web at higher-than-intended velocity. Consistent share travel on stone-cleared soil maintains tubers in a steady, predictable flow through the web separator \u2014 reducing the velocity variability that produces bruising even without stone contact.<\/p>\n<\/div>\n<div style=\"flex: 1 1 200px; background: #fff; border: 1px solid #e0e0e0; border-top: 4px solid #2d5f2d; padding: 16px 18px; border-radius: 0 0 6px 6px; box-sizing: border-box;\">\n<p style=\"font-weight: bold; color: #2d5f2d; margin: 0 0 6px 0;\">Mechanism 3: Web separator free-flow<\/p>\n<p style=\"margin: 0; color: #555; font-size: clamp(12px,1.3vw+8px,14px);\">A clean, stone-free soil stream allows the vibrating web to run at optimal separation efficiency \u2014 tubers flow smoothly across the web without congestion. Stone accumulation on the web (from un-cleared fields) creates local congestion zones where tubers pile up and contact each other at elevated velocity \u2014 producing tuber-to-tuber bruising in addition to stone-contact bruising.<\/p>\n<\/div>\n<\/div>\n<p>Korean highland studies consistently show that stone-cleared field potato harvest produces 15\u201330% lower bruising rates than un-cleared field harvest at the same working speed and soil moisture conditions. For fresh market potato where bruising is a Grade 1 disqualifier, this difference directly translates to 15\u201330% more Grade 1 tubers reaching the market from every harvested hectare \u2014 a revenue improvement that compounds the yield and grade benefits of stone clearing described in the stone clearing ROI article.<\/p>\n<h2 style=\"font-size: clamp(20px,2.8vw+10px,30px); color: #1a1a1a; border-left: 5px solid #f07c00; padding-left: 16px; margin: 48px 0 20px 0; line-height: 1.3;\">EP-AWB-1600 Maintenance Between Seasons \u2014 Keeping Harvest Readiness<\/h2>\n<p>Unlike the THOR 2.4 and PSW-3200 which are used intensively in spring, the EP-AWB-1600 operates in a concentrated August\u2013September harvest window after 5\u20136 months of storage since the previous season.

On un-cleared fields: embedded stones deflect the share intermittently, producing variable harvest depth and stone-to-tuber contact in the share path. The vibrating web handles mixed stone-and-soil loads \u2014 stone fragments cannot fall through the web like soil particles, accumulating on the web and progressively reducing effective soil separation.

(2) Wet clay-silt soil during wet harvest conditions \u2014 Korean highland silt-rich soils become sticky when wet, adhering to web chains rather than falling through. (3) Large organic matter chunks from incorporated green manure or crop residue in the soil \u2014 incompletely decomposed plant material forms mats on the web surface.
