I guess some people have a reason to want a tank that will hold 100 + gallons. And only need a 12 volt pump.. I use a 15 gal per acre mix, I think its the most common. I usally never run it dry, meaning theres always some left in the tank when I refill. If u have a 100 gallon tank,
90 gallons of spray will cover 6 acres,.
I have, and love my 35 gallon sprayer,. i can spray 2 acres before I have to fill again, and get back at it. Takes about 10 min to reload.
Unless u dont have a supply of water handy,. I think, you should consider how nice it is to have just about the right amount left over,..Especially when u might want to switch to another chemical like 2-4-d.
I sprayed 120 gallons today and belive u me I waz real happy, I didnt have to tote around a tank of 100 + gallons in the rough terran I had to run on.
As far as 12 volt pumps go,... they are great,..Even the $100.00 pumps will do a professional job for years. I can spray about 100 inches wide,. And, Iam sure they are good for at least 144" I sprayed all of the 120 gallions today out of a hand wand.
2 each his own,. But lotsa people think they need to spray it all in one shot,.,And thats there choice. But if you dont come out just rite or close on your batch of round up ..where are you going to store 50 gallions ..so you can change to a 2-4-d mix? Unless u are workin in a desert, And didnt bring a supply of water with u, maybe u should rethink your tank size.
