Spray tip selection for Backpack sprayer

guys,

Looking to find a good wand and/or boom set up for the Shurflo backpack sprayer I am going to purchase. I plan to treat 10-12 lawns this season, all smaller resi's (under 8k sq ft). Will spot treat some, but will inevitably have to blanket treat a few too due to weed pressure.

Ideally, I want to be able to cover the open turf areas without waving the wand back and forth. (I have heard that the stock wand/tip with the Shurflo would probably not allow for this, and that you cannot change out the tips on this wand.). Wand waving just seems way too variable. Is there a wand/tip setup that will fit this sprayer that you would recommend? Or how about a mini-boom type deal? The one thing I worry about with a boom is that I cannot cover the tight areas or sensitive boundaries (like along landscaping).

Thanks.

GreenDoctor and Ric have recommended a ??TeeJet?? flat fan nozzle set up. Do a search about nozzles and you should be able to find it.

Fan type for sure .
Spray like you are mowing , in strips , best to use a dye marker so you know where you have been, well , if it's a golf course , forget the dye.
I tried a boom one time , not enough flow to support the 2 or more tips .
Besides, the Surflo does not pump enough fluid for big jobs , too slow

Its done all the time. Wave the wand. Its just like spray painting. Skill. Practice with water on cement. After a few minutes you will learn how to apply it evenly, and establish the width of your swath. And determine the gallons per 1000 feet. This way you can do large areas and still reach into tiny spaces. Not much different than using a spray gun and hose. Do not wave a flat-fan type nozzle. Keep the pressure low and you can get more sqft out of 4 gallons. Apply less water and save fill-ups.

I don't blanket lawns with a backpack, but I know you should walk in a straight line. Don't wave it, and keep steady pressure. Use a tee jet. I'll double check what what size, pressure etc for you.

What I like on the end of a wand is an Teejet AI11003 or AI11004. At normal walking speed, you can put down a gallon per 1000 with very good coverage and no overlapped or skipped areas. The coverage and accuracy is near that of a tractor mounted boom. Those nozzles also have the advantage of drastically reducing drift. A conventional fan nozzle mists and is prone to moving off target.

So, what I am hearing is to rig up a different wand than the Shurflo stock wand, and use a teejet flat fat set up (thanks greendoctor). And, don't wave the wand back and forth, correct?

waving the wand back & forth means you'll over and under lap severely .
it's a very poor method of applying to large areas

Walking speed, height of nozzle , uniform overlap. solo model or lesco model backpack. 8004 lp flat fan tip. 80 stands for 80 degree spray angle. 04 stands for opening size. lp is low pressure. at 15 psi this will deliver 4 tenths of a gallon per minute. walk 2.3 miles per hour or 3.4 feet per second. keep 18 to 24'' off the ground or about knee high. spray 2 and 1/2 feet apart and overlap 6''. this will provide good even coverage.

Never use a TeeJet flat fan nozzle on a backpack or handheld..You can get away with it for awhile but its a horrible method..The TeeJet cone nozzles are far better in that type of app
