The reaper is a tool that is used by farmers to harvest the crops that the farmers planted as soon as they became ripe. Steel plow farming is a tool that's used to break up the soils so it can be used for planting.

Both of these tools improve the productivity of the farmers and help them in fulfilling the orders that they got in time.
