2 acres for a backpack sprayer

[strutbuster_10]

Is 2 acres to much for a backpack sprayer. I will most likely need to do a few blanket apps of a 3 way over the next few years and maybe a blanket app or two of tenacity. After I get the weeds under control blanket apps should be a rarity. I was trying to decide if a 15 gallon pull behind is really necessary?

There is a long thread on the Chapin 20V battery powered backpack sprayer in the equipment forum.

It puts out 0.5 gpm so for a 1gal/ksf that is two minutes, it is 4 gallons so about 8 minutes between fill ups.

It would take 88 minutes of continuous spraying plus fill up time for two acres.

I definitely would not want to hand pump but is two hours or so (depending on how efficient you can refill) too much for you?

How much time you have on your hands???

A typical backpack rate is 1 gallon per 1000 sq ft. Or about 10 backpacks per acre. I don't do a lot of large area spraying with a backpack but I would guess it will take 20 minutes to mix and spray 1 entire back pack. That puts 2 acres into a 6 plus hour event.......

Someone please correct me if you think I have over estimated

Andy use to do an acre with a pump sprayer, so you should probably be able to swing 2 acres with a backpack.

You could do it but I think it would be very difficult. I wouldn't do it. I value my time more than that.

10k square feet takes me about 45-60 minutes with the Chapin battery sprayer. Plan on 4x that amount of time for an acre.

I end up refilling once or twice on my 1 1/2 acres of turf with my 30 gallon pull behind. I can't imagine doing blanket sprays with a 4 gallon backpack sprayer on the whole thing in any normal amount of time I have available. I also question if it is more accurate. To do a quality job for things needing precision you need to go over it several different directions. Think you're up for spraying it two different directions?

I recommend getting a sprayer with pump powered spray wand you can use for the edges. Precision is more difficult on small spots where you don't want to spray adjacent plants - you have to be more concerned with drift. What I find myself doing for things like triclopyr / 24D is blanket spraying everything but the 5 feet in front of stuff it could potentially damage and then stopping to use the pump operated wand sprayer, which has great control and about a 20' reach.

I have a backpack and a tow behind. I have tighter areas I can't even get my tow behind into. I would highly recommend the tow behind and another smaller sprayer. There are also times you only need one or two gallons and the tow behind would be cumbersome.

Yep I still use my back pack sprayer. just not the big blanket sprays.

That's what I was thinking. I'm thinking of getting a 15 gal pull behind but that even sounds a little small. The nice thing is I have access to a 50 gal tractor mounted sprayer that is on a three point hitch. Maybe the best thing to do is use it when I need blanket sprays.

Northern has this pull sprayer http://www.northerntool.com/shop/tools/ ... _200646314 plus you can use a $20 promo code.

I currently have one and have been using it weekly, it only does a 40in path but for the money it's cheap and works.

I have a Fimco 25 gallon pull behind. I agree that for two acres you need that, or bigger.

FWIW, I usually just apply in one direction. Unless I mess up my pace or something, I don't bother adding a second pass, but I have been doing this for a while. I also live on the edge and don't bother with tracker dye.

I do 37k in 3 hours 6 beers. Only put in 3 gallons out 4 due to weight.
