As a matter of fact, in the back of my ford 951 rotary cutter book, it lists torque ratings for grade 2, 5, and 8 1/4 inch thru 1-1/8 in foot pounds, and newton meters.
I'll list them across as follows:
size grade 2 fp nm grade 5 fp nm gr8 fp nm
1/4 6 8 11 15 14 19
5/16 13 18 21 28 25 34
3/8 23 31 38 52 55 75
7/16 37 50 55 75 80 110
1/2 57 77 85 115 120 165
9/16 82 111 125 170 180 245
5/8 111 150 175 240 230 310
3/4 200 270 300 410 440 600
7/8 280 380 450 610 720 975
1 350 475 680 924 1035 1400
1-1/8 450 610 885 1200 not listed
hope that helps
