Motor on right might be pressuring the sprinkler water also----- Motor on left is lifting water to surface sending volume this and maybe more smaller motors to pressure sprinkler.
Otherwise hobby's got er nailed. As he says the fertilizer injection pump is there behind the horizontal black water discharge pipe running between the two motors.
it doesn't look like a large capacity sprinkler. Not 10 inch pipe out of the top elbow. But it might not be in the system.
Diesel is high priced choice, so may be in an area without natural gas or electricity. Does not look to be in US. Guessing middle east or eastern europe.
Neat instalation. any more shots of it??

Second look I would say Hobby had it. The right motor may be just generating the elec to drive the sprinkler and the fertilizer pump using the same diesel supply. Expensive water .

Also notice the huge wasted area around the well/pivot site.
Probably as SW said not in this country.
When I enlarged the photo there is a good sized grain bin and other buildings in the background just beside the right leg of the pivot.
Forgot there is a shower shed over the generator.
anything else we missed?

Just the hole in the ground under that gray gearhead behind the air cleaner of the left motor. Wonder how deep that water is.
The sprinkler control box is different and the collector ring is Valley style.
Come on justnow give us the story.

Looks like Cat yellow on the pump module and genset. The engines for these units are typically sized for a specific task. Quite a difference in the size of engines for the two units. Load requirements and fluctuations from a genset can put unique demands on an engine. Best to have one dedicated to that task.
Location is the curious question. May be just the time of day but that sky looks like the desert southwest. Hard to make out the lettering on the generator base.

Isc76cat says it pretty well. I look at one regularly in a spot where elec. is not close. This is the poor mans way, we drive a generator off the gearhead end of the drive line to pull all the power from one motor. Much more reasonably priced but takes a motor with 35+ extra horsepower.
1. The generator needs a constant 1800 rpm or close. The water lift needs 180 hp in spring and 210 hp in August. So we have to change pulleys on the generator at least monthly----- not a simple thing keeping everything matched.
2. Isc76cat nailed another issue. When the sprinkler needs to run at 90+% speed the pull on the generator requires more Hp. So a single motor setup limits the sprinkler to lower speeds.
3. Seperate gen set motor lets you move the sprinkler without water in it. One motor pumps water every time you start up to move the sprinkler.
4. More gearhead wear from the side belt drive of the generator.
5. Diesel ----- probably drinking 16+ gallons an hour for the two motors.
Agree Isc76cat, seperate is best but probably adds $35-40K to the cost. The picture is a top notch layout. Probably crowding 400K investment for 125- 300 acres. The other way to water a crop is buy Iowa farm land ----- another expensive answer.
