For longevity concerns AIM Command adds:

• A bunch of AIM Command solenoids. They last a long time but in my opinion, if you want to fertilize with your sprayer you need to
  • Remove all of the AIM Command solenoids and replace them with on/off check valves
  • Put weatherpack plugs on the wiring where you disconnected the AIM solenoid so that you protect the wiring
• Quite a bit more wiring
  • For every AIM Command solenoid there is a sprayer half to the weatherpack connection and there is a solenoid half to the weatherpack connection. Unfortunately the two wires that go into the sprayer half of the weatherpack connection are not protected in any way. The insulation on them cracks with enough exposure to the sun and that is a recipe for getting corrosion going in the harness. The harness is not cheap.
  • There are AIM Command modules and they can fail.
  • There is an AIM Command pressure transducer in addition to the other pressure transducers
  • There are more switches and wiring to the cab

I think AIM is a good deal but it’s not all roses. You need to keep one or two spare solenoids in the sprayer. You should take a solenoid apart and study the individual parts of a solenoid that you can purchase. You should have some of those parts on hand.

You should examine all of the extra harnesses and you should consider protecting the exposed wires from the sun in some way. You should keep close track of zip ties that are holding those wires on and replace/supplement them regularly to prevent damage to the expensive harnesses.

If you keep on top of it and do proper repairs when you have issues, it will treat you well for a long time.

If you do “good enough” repairs and if you neglect it, it can become less reliable with time.

I do feel it is worthwhile to have a second nozzle body and a set of nozzles that will allow you to finish your load if AIM fails in a way that prevents you from finishing.

Most AIM equipped sprayers have two nozzle bodies. One has the AIM Command solenoid on it and one has an on/off check valve. If you have a failure and if you’re set up correctly you can just shut AIM off and open your on/off check valves up and you can keep spraying without AIM.

If I was looking at two equal condition sprayers and one had AIM and the other did not I would probably pay 5 or 10K more for the AIM equipped sprayer. There are hassles but I think it’s worth it to have control over your pressure over a wider variety of speeds.

That being said, if I stumbled upon a sprayer that was in really good condition and was priced well but did not have AIM and I thought it was unlikely I would come within $10K of that price on an AIM equipped sprayer of equal condition and hours...well heck, I guess I feel that I can survive without AIM.
