I need to know your rpm and your tire size and what gear you need speeds for.

16.9-34 2377 rpm
1st std, 3rd std- 1st=2.96, 2nd=5.23, 3rd=7.33
1st fast, 3rd std- 1st=3.4, 2nd=5.23, 3rd =7.33
1st std, 3rd heavy- 1st=2.96, 2nd=5.23, 3rd=6.56
1st fast, 3rd heavy- 1st=3.4, 2nd=5.23, 3rd=6.56

I can email you an excel copy if you would like.

If you could give me the speeds for 1, 2, 3rd with both size tires it would be greatly appreciated.

The 560 was available with a standard 1st gear and a fast 1st gear. It was also available with a standard 3rd gear and a heavy tillage 3rd gear package that also effected the 4th gear speed. The heavy tillage package slowed down both 3rd and 4th. So hopefully I can explain this so that you understand. All speeds are at 1981 engine rpms.

18.4-38 tires
std 1st and std 3rd- 1st=2.76, 2nd=4.88, 3rd=6.84
fast 1st and std 3rd- 1st=3.17, 2nd=4.88, 3rd=6.84
std 1st and heavy 3rd- 1st=2.76, 2nd=4.88, 3rd=6.12
fast 1st and heavy 3rd- 1st=3.17, 2nd=4.88, 3rd=6.12

16.9-38 tires
std 1st and std 3rd- 1st=2.63, 2nd=4.64, 3rd=6.51
fast 1st and std 3rd- 1st=3.01, 2nd=4.64, 3rd=6.51
std 1st and heavy 3rd- 1st=2.63, 2nd=4.64, 3rd=5.82
fast 1st and heavy 3rd- 1st=3.01, 2nd=4.64, 3rd=5.82

hope this helps
