Sprayer set up

I have recently bought a used Hardi pull type sprayer. 300 Gal tank, 30 foot boom. It has a hydraulic roller pump on it now, not sure if that is a good thing or bad (I'm thinking bad as I'm not sure my old tractors have the hydraulic capacity to run it) The nozzles on the sprayer are incomplete, local teejet dealer didn't even recognize the brand of nozzle currently on it, either could the Hardi dealer. I'll likely change out the nozzles to teejets, I can do this for about $200. My question is about nozzle spacing. I see most sprayers have 20" nozzle spacing for 30" rows. This allows much overlap which I understand is exactly what you want. I drilled my beans in 14" rows this year. Could 20" nozzle spacing work with 14" rows?? Other uses for the sprayer will be hayfield burndown, and I may also try spraying a foliar fertilizer on some hayfields just to experiment a bit. In future years, I'll likely use a planter with 30" rows for my soybeans or any other row crops.

Also, with 14" rows, that doesn't leave much room to get a tire through the row when it comes time to spray. I'm thinking about using my Farmall C to spray with as it has 10" rear tires, all my other tractors have 15" tires or wider. Does the C even have a chance at running a hydraulic pump on this sprayer? Is 2" clearance between the tire and soybean plants enough to not cause trouble? Thanks for any help you may be able to offer on these questions.

There is NO WAY you are going to run a hydraulic motor with a C! Nor is there any way you are going to stay in the rows. Spray them diagonal.

ok, forget using the C with the hydraulic pump. Would the C get the job done with a PTO pump? I wouldn't have to fill the tank full, I only have 50 acres to do, my largest field is 12 acres.

put a pto roller pump on it

On a field sprayer, nozzle spacing has nothing to do with row width. The nozzles are spaced for solid coverage. I have never had a hydraulic pump, but don't think I want one.

Need 10 gallons per acre to get a good kill on most herbicides. 300 gallon tank will do 30 acres. 300 gallon sprayer is probably too big for a C. The beans will pop back after being run over.

My beans are on 15 inch rows and the sprayer tractor has 18.4 tires---sprayed twice per season (RR's) and very rarely see any damage by harvest--just don't drive right on top of the row.

I think the C will be ok with a 300 gal. pull type sprayer. My dad had a 300 gallon sprayer and he used his D-14 Allis with no problems and we had some hills also used his 820 Deere utility tractor. I like the idea of a pto pump much better than the hyd pump. Tom

A guy I worked for used his Honda rancher to spray beans with a 300 gallon sprayer and a 12 volt pump, did all his pasture too. He ran 300 momma cows and about 1200 acres row crop. The C is plenty big to pull it, not sure on the pto pump, I've never had to use one.

I have a roller pump, pto driven, by a 540 pto Allis,on my sprayer. The pump doesent turn fast enough, at 540, and will only make around 30 psi pressure. Wish I had a 1000 rpm pto.

No on the hydraulic pump question. A Farmall C will be fine with a 300 gallon sprayer. I prefer a centrifugal pump over a roller pump.

I use a roller pump with a 40 ft sprayer on 20 in centers. Use blue tips. Run 30 psi at 6 mph. 15 gal per acre. But I am belt driving the pump from the PTO. Had it geared up 3 to 1. Would pump more than could bypass had to much pressure at nozzles with by pass open. Geared it down to 2.2 to one. About right. Not hard to do. Just hinge the pump and make pulleys for pump and PTO.farm store will have all hubs and pulleys. Weld together. Will try to post picture. 618 599 8041 if questions. Vic

I gave up on roller pumps long ago. A belt driven Ace PTO centrifugal pump will give you all the pressure and volume you need plus some. Costs more than a roller but abrasive herbicides wont wear it nearly as bad and it will last longer than a roller pump. You will want to replumb to put in a bypass valve in place of the relief valve it might have on it now. I used to pull a 400 gallon sprayer with a 30 foot boom with an SC Case. Put many,many acres through it. I did have to stay away from softer wet spots. Pulling a stuck tractor out of the mud backwards with a full sprayer attached is near impossible without the sprayer jacknifing. On my sprayer i mounted the Ace pump on the sprayer and ran a PTO shaft to it but you could put the pump straight on the tractor PTO and run your hoses to it if you want. It's just personal preference.

You sure you dont mean 30 gallong sprayer? 300 gallons of water is 2400 lbs. Not counting the weight of the sprayer itself. Going down a steep hill, it would pass you.

A "C" on a 300 gallon sprayer is nuts. 2400 lbs of water pulled by a 2800 lb tractor.

That 20" nozzel spacing dates to the time all corn was planted in 40" rows and every other nozzel was a drop tube spraying out sideways to just get the bottom of the corn plant and weeds and not the top of the corn plant as at that time doing over the top spraying would kill the corn. The nozel over the row was replaced with a blank so it was shut off. When you wanted to spray like a wheat field you took off the drops and blanks and put a nozel on each spacing. And you adjusted the overlap depending on the type of nozzel by adjusting the height of the boom. When 30" rows came the normal if the drops were adjustable on boom as with a hose between they were moved to a 15" spacing or on pipe type booms they were drilled at the 15" spacing with more adapters put on and used while the orignal non used 20" spacing outlets were closed off with the blank nozels. You just had to calibrate differently as all nozel charts were set up for the 40" row spacing and for consistance they were kept the same. With todays moddern sprays for over the top spraying and no drops being used it makes no difference.
