| I would probably take the 8320 given those options and those jobs. Planting ivt would be nice but not necessity. Fall tillage pst is fine. I really don't feel the 30's had any cab advantage. In fact our 30 has more dust in cab and sloppier steering column and door opens harder than the 20 with double the hrs. Really the biggest difference is 8.1 vs 9.0 engine. Both work well, 9 L has potential for EGR valve problems and variable vane turbo issues. Love driving the 8430 but I really like the 20's too.
Again with info given I'd take 8320.
Edit to add: check hyd flow on both. 20's came with 43 gpm being biggest factory pump option. 30's had 60 gpm factory option. Is your planter ccs? If it is you might consider the 30 over the 20 if the 30 has big pump. For a 16 row hopper planter a 43 gpm pump keeps up easily even with hyd drive.
