Wheel Skidders Typical Application Description (relative to work application) Low

Intermittent skidding for short distances, no decking. Good underfoot conditions; dry floor, few if any stumps, flat/level terrain with low skidding resistance. Medium Continuous turning, steady skidding for medium distances with moderate decking. Good underfoot conditions; dry floor with few stumps, gradual rolling/moderate terrain with medium skidding resistance. High Continuous turning, steady skidding for long distances with frequent decking. Poor underfoot conditions; wet floor, numerous stumps, steep terrain with high skidding resistance. Skidding loads less than 4536 kg (10,000 lb) in flat terrain (0-8% grade) with low skidding resistance. Medium Skidding loads up to 4536 kg (10,000 lb) in moderate terrain (8-30% grade) with medium skidding resistance. High Skidding loads over 4536 kg (10,000 lb) in steep terrain (over 30% grade) with high skidding resistance. Load Factor Guide — D SeriesWSK Low Skidding loads less than 6350 kg (14,000 lb) in flat terrain (0-5% grade) with low skidding resistance. Medium Skidding loads up to 7257 kg (16,000 lb) in moderate terrain (5-10% grade) with average skidding resistance High Skidding loads over 8165 kg (18,000 lb) in steep terrain (over 10% grade) with high skidding resistance. Load Factor Guide — 527 Low Skidding loads less than 6360 kg (14,000 lb) in flat terrain (0-8% grade) with low skidding resistance. Medium Skidding loads up to 6360 kg (14,000 lb) in moderate terrain (8-30% grade) with medium skidding resistance.
