3 point sprayer help

[Spike56]

For anyone interested: After advice in the forums and a few calls, I purchased Camlock fittings for the 3-point sprayer. Makes the hookup and clean up a breeze compared to without them. I can now easily fill the pump with RV anitfreeze when done and store by itself. Just sharing

Tie the chain around drawbar to hold pump while on.

Are these pumps stainless? From my experience cast iron pumps should be treated as disposable.

LOL, Yes, I did ! Was just showing the connections for the pump in / pump out.

Hypro 7560XL (8 roller). Not sure what you mean by disposable ?

That looks like a good pump. The basic cast pumps rust like no tomorrow especially when spraying glyphosate. What I was saying is the cast pumps are essentially a throw away item. They won’t last. Expect to buy a new one each season as they will corrode.

Oh boy, You hit the nail on the head !
The ENTIRE purpose of my original post was exactly what you mentioned = the cast iron pumps were giving me fits. I could NOT ever keep the pump from rusting / corrosion to the point of failure. One reason was the inability to COMPLETELY drain / flush the system "enough". That is, I suppose I could have run multiple 100's of gallons of clean water, followed by gallons of anti-freeze..... otherwise, .... the pump was almost "disposable".
So, I upgraded to the Silver Series, AND added the camlocks. Makes it easy to drain and fill the PUMP with anti-freeze (the manufacturer said "no diesel").
