does anyone in this group have specific idea on how big or what size motor

Thanks,

A 60 or 75 horsepower electric well motor would be a common size here in
eastern Nebraska. The well motor size depends on the operating pressure
needed for the pivot and the static water level of the well. Typical
operating pressure nowadays is about 35 psi. Older pivots used to run about
75 psi. Add about 6 horsepower for the drive motors and endgun booster
pump motor on a standard (1/4 mile) system. The local well driller is the
best source of information for motor sizing.

I took a quick look on a couple manufacturer's websites for pictures of
sprinkler heads. They had mostly sales propaganda and not much useful
information. There are a few pictures he

The major brands of pivots are Valley, Zimmatic, and Reinke,
(Electrogator). All three companies have websites. You might be able to
request sprinkler package information directly from them. All three of the
companies sell their systems through dealer networks. There are getting to
be many used pivots for sale also. You could find them through farm sales
circulars or through local pivot dealers.
