In "Follower", Heaney uses words such as "globed" and "strained". These are words which show that life in the country is difficult and that the work involved can be strenuous. They do however, produce good images about the country, because "globed like a full sail strung" conjures up many ideas of the hard work involved in life on the farm, and "strained at his clicking tongue" not only shows the difficult job of the horses, but through the effective image produced, it shows the reader how skilled Heaney's father is.
Other words which show the skill involved in country life include "expert", "without breaking" and "exactly". These all show the reader what an accomplished farmer Heaney's father is, but they also have another use. They show us what country life is like, as mentioned previously, by illustrating how much skill goes into a seemingly mundane task such as ploughing a field, but they also produce very effective images.
"The sod rolled over without breaking" not only illustrates skill in the country, but also beauty. The idea of freshly ploughed soil, perfectly formed adds to the readers perception of the country as a beautiful place, and so country life is also portrayed as very happy.
However, despite these nice images, Heaney also uses such words as "sweating" and "stumbled" alongside them. This means that he wants to show country life from both angles and explain to the reader that while it may look nice and the visual rewards may be great, it takes a lot of effort to get to that stage in the first place. The images which he uses to show this are effective because "the sweating team" can be pictured by the reader as man and horse working together in harmony to produce a perfect field,
