I am getting ready for the maiden run with my new 60 gallon sprayer. It has 5 nozzles spaced at 30" on a 12' boom. With 30" spacing, the nozzle height above the crop canopy should be 30". So, I am thinking about re-plumbing and setting the nozzles at 20" spacing. This would allow me to lower the height of the sprayer down to 20". So, given the following factors:
- Novice Operator
- Small tractor
- Four acres of gently sloping terrain (but not hilly)
- A few holes here and there that I plan to fill in, but they do look a bit dangerous if I hit one with a full tank on terrain that slopes toward a hole that a rear tire dropped into.
- I can keep the payload down to 30 or 40 gallons and adjust my chemical content so that one tank would cover one acre.
- I can keep the speed down - I have lots of time.
So, what is the crowd wisdom? Should I just make the mods, or give it a go with the 30" spacing and see how it works? (30" puts the 3 point hitch just about all the way up.)
Re-plumbing would only cost about $60. (two nozzle bodies, and a set of smaller nozzles.). It seems like cheap insurance to reduce the risk of a rollover, but then maybe I'm overthinking this and the risk isn't that great. I will probably do all of the above: re-plumb, use a partial tank, and adjust my tank concentration so that I can keep the speed down around 2 MPH.
Thoughts? Additional advice?
