Therefore if the rear cutting units have the same ground weight as the front cutting units and are mowing less grass then the effective height of cut on the rear cutting units can be lower causing a height mismatch in the aftercut appearance. Rear cutting units cut approximately 23% less grass due to the overlap of the front Front cutting units cut the full width of the reel Rear cutting unit paths Front cutting unit paths Mowing, equipment safety, equipment maintenance 10 11 ATC Research Facility, 2007 12 ATC Research Facility, 2007 13 Bermudagrass Cynodon dactylon or hybrids of Cynodon dactylon x C. transvaalensis 14 Karnataka Golf Association 15 Jaypee Greens, Delhi 16 Willingdon Sports Club, Mumbai 17 Royal Calcutta Golf Club 18 Seashore paspalum Paspalum vaginatum 19 Seashore paspalum green, Bombay Presidency GC 20 Seashore paspalum tee, Bombay Presidency GC 21 Panya Indra GC, Bangkok 22 Seashore paspalum at Hanoi 23 Manilagrass Zoysia matrella 24 Zoysia matrella at Singapore Island CC 25 Zoysia green at Wack Wack GC, Manila 26 Zoysia matrella rough at Chiba, Japan 27 Carpetgrass Axonopus compressus 28 Carpetgrass at Thailand 29 Carpetgrass rough at Manila 30 Carpetgrass fairway at Thailand 31 Carpetgrass fairway at Thailand 32 33 Kentucky bluegrass fairway, Japan 34 Tools for measuring turf performance 35 Clegg hammer for measuring surface firmness 36 120 clegg 100 80 60 C3 factor(type) C4 37 120 100 5 clegg 5 0.1 0.1 80 60 C3 factor(type) C4 38 Stimpmeter 39 12 11 stimp2 10 9 8 7 C3 factor(type) C4 40 12 11 10 stimp2 5 9 5 0.1 0.1 8 7 C3 factor(type) C4 41 42 Fine fescue Bentgrass Kentucky bluegrass Perennial ryegrass 43 44 45 46 47 Bermudagrass Cynodon dactylon or hybrids of Cynodon dactylon x C. transvaalensis 48 49 50 51 52 Seashore paspalum Paspalum vaginatum 53 54 55 56 57 Manilagrass Zoysia matrella 58 59
