Bad pump on 45 gal sprayer

Rule #1 with sprayers whether it be electric, PTO or airblast, make sure it is running/working before loading chemicals.

You say about 5 volts is getting to the pump motor? Doesn't the motor require 12 volts?

So, when I bought my 1025R last January, one of the attachments I purchased was the 45gal sprayer that attaches to the 3pt hitch. I've used it twice, and love it, however, this week I loaded it up to spray and the pump wouldn't turn on. I checked that power was getting through the on/off rocker switch to the pump, which it was. (About 5v) So, I'm assuming it was a bad pump.

Anyone have any experience with this? I'm probably going to haul it to the dealer since it is barely 6 months old. Is this a common problem? If so, I'll probably buy an extra pump to keep on hand in the future.

Biggest lesson learned here was to test your pump before you fill up your sprayer. Not fun having to off-load 45 gal of pesticide mixture and apply it with a 5gal backpack sprayer. Feet hurt for 2 days.

Make sure the connections are good. With water in the tank And tractor engine running so you have full voltage, turn on the pump with valve set to the spray wand and recirculate. Rap on the pump with a wrench. When mine sticks, that fixes it. Be sure to fully rinse the tank and run the pump to clean spray nozzles, spray wand, and recirculation line. rinse tank and flush the systems three times. Get pump rinse fluid at Tractor Supply for the final rinse.
If the pump still doesn't run, remove it from the tank, carefully disassemble it, remove pump from motor, rinse the pump (not the motor). Reassemble the pump and motor, test run it dry (briefly). If it works, reinstall it and don't forget to completely rinse/flush the system after you use it.
All that has worked for me with the same sprayer.

Should have 12 volts at pump. Try to bypass rocker switch. I have replaced quite a few especially if exposed to any moisture. I changed my pumps to Remco 5500 5.3 gallons per minute they work great. They also have smaller versions.

Same happened with mine. Used it a couple of times, then pump was dead. It goes a long time between uses and I thought perhaps liquid froze in the pump, damaging something, but have no confirmation of that.
Ordered a new pump from Superior-Tech (they make the 45-gallon sprayer for Deere).

I've had them melt the rocker switch and cause it not to work while I had fire on the ground. I've also had the diaphragm on the pump go out. Haven't had much issue since switching to Northern Tool sprayers.
