been reading old posts but still undecided on whether to look for 16.9r30 or 14.9r34 for an 8000jd. tillage like plowing and field cultivating, then baleing. possibility to use it for row crop cultivating in the future w/ some side hills. also, would you rather have a 97 8100 with 8.1 or 95 8300 with 7.6, same hours 8300 a little cheaper. thanks
