The New Holland 9000L Series mod for FS25 is an optimized version of the New Holland 9070L combine harvester, with improvements:

New 9090L engine for increased power.
Included medium and wide tires that meet the manufacturer's specifications.
Cornering angle changed to 90° (real car angle), making it easy to move between lanes without having to back up.
Corrected tank size - now 240 liters instead of 270 liters as stated in New Holland's specifications.
Corrected rear indicators - they are now orange, as in the real model, instead of white as in the original.
