Perfect! And is the manual sprayer a Field King?
Donât know
The Field King at Amazon looks good
The carrying straps are whatâs important. If theyâre not robust with padded hip straps and a chest strap you wonât be comfortable working. The Field King has half a dozen pictures that look very good.
Field King Max 190348 Backpack Sprayer for Professionals Applying Herbicides Amazon.com
I made my first backpack sprayer for WFP many years ago. I took the cheap piece of crap straps that came with it off and put the straps from an old backpack I had for hiking on.
Three pumps per window to wet the glass and about three pumps to rinse after scrubbing. Canât clean the frames not enough water. Traditional guys never clean the frames anyway. Youâll use about a quart per window.
No shut off valve needed. You pump when you want water. I had a shut off valve just to stop it from leaking out in the truck.
