I am a Grower and I want a tool to water my fields easily

Often, water supply is domestic with low pressure. Therefore, only few stationary sprinklers can be used at a time requiring lots of shifting of sprinklers down a planted area. The result is that to water a newly planted area, a lot of effort and time is used. Watering is not consistent as sprinklers make a round profile and beds are rectangular. They need to overlap creating areas which are watered twice while other sections are missed.
