How did new inventions make frontier farming both easier and more difficult

The correct answer is: frontier farming became easier because there were new tools that helped break the soil faster. However, even though there were many useful tools for farming, it was also difficult for people to get a job since the machines were taking their places.

For example, there were new machines such as farming with windmills, steel plows and reaping machines which made harvesting quick and easy.

Nevertheless, it was hard for farmers to pay for these tools and put them in debts. They dealt with economic problems as crop prices dropped and their debts grew.
