Quoting from the Nebraska Tractor Test No 594, done on the John Deere 720 Diesel (the 730 used the exact same engine) lest "L"-OPERATING MAXIMUM TORQUE:

% of rated rpm (engine) / % of rated speed torque

100/100
95/108
90/112
85/112
79/114
75/115
70/116
65/116
60/113
54/111

My apologies for not being able to format this so that it is easier to read.

I do not have the figures for the 560D- my book only lists the 450D so feel free to list any figures for the 560. Here are the ones for the 450D, however:

Nebraska Test No. 608 Test "L":

Engine rpm/ % of rated speed torque

1450/100
1377/102
1305/102
1232/103
1160/103
1073/101
1015/97
942/95
884/93
797/91

At least THIS IHC Diesel engine doesn't match the torque rise of a John Deere.
