Would think 3-4 plow, 10 ft tandem disc, 4-6 row cultivator, 6-7' brush hog, 8-10 ft grain drill, 3 tooth subsoiler for starters.
That model was a good size (not the biggest) farm tractor in its day. If running in good condition and all available HP is there, should handle most attachments you find for its mid-60's day.
More about what you plan to do with it and what kind of field or forest you plan to tackle for food plots would help with answers.
