D6N LGP vs XL

Looking for some input from anyone with experience with these tractors D6N LGP or D6N XL? . Quite a bit of difference in the two machines when it comes to the blade. LGP has the 13.4 wide blade and sets out from the tractor quite a bit more for the longer tracks than the XLs 10.7 wide blade. I do farm work mostly clearing -ditch work- building pads -ponds exc. Needing a dozer that will work well with a 320 excavator.
