KD Modding and Borrowed Parts Modding have teamed up working on this IH 856 for fs25.

They not only transformed it, but also added some features, so instead of just calling it IH 856, they named it the IH 56 series, adding 756, 1256, and 1456.
They didn't add the 656 because it's a slightly smaller tractor and they would have had to make it smaller as the others are quite similar in size.
It has: an animated fan, an IH front loader, 6 brands of rear tires, 2 variants of front tires, twin tires, 3 exhaust pipe options, front loads, 3 cabin options, cable and awning, animated sensors and original 22 functions.
Redesigned parts: front IH logo, rear 3-point transmission, gearshift levers, pedals, parts of all cabins, new front discs, new sensors. front weights and new specification cards.
