3-pt Mounted Sprayer Recommendations

My questions are:

Do you folks buy your sprayers or fabricate them?

How large of a tank should I consider? My tractor is 38 pto hp.

I would like to kill the undesirable weeds and brush, leaving the grass unharmed. Any recommendations for the type of spray would be appreciated and it's implications on potential hay later in the season.

Lastly, I do know my weeds, but there is one particular type of weed that grows everywhere in our fields. When I was a kid, we called it a "stick weed"! It grew about chest high, had about a 3/8" stem with half-hand size leaves on it and the whole plant was green. Any idea what this plant might have been called? We use to strip all of the leaves, except for the top, and toss them around like little spears!

Any advice would be appreciated.

Thanks in advance,
Bill

We tend to use 10-20 gallons per acre for good coverage & mixing, Decide on how big you want, 50 gallons would be fine, you probably can use a 100 gallon if you wieght your front end at all.

If you have alfalfa or clover, that is DIFFICULT to find a spray solution to weed problems. If it is all grass hay, then you want a broadleaf spray. Different ones handle different weeds better or worse. The real good ones that really kill off the bad weeds are costly. On the other hand, 2,4D is very cheap & kills or supresses most broadleaves. I'd ask for local advise on what works well for the weeds you have.

Mostly you end up buying 2 gallon jugs of chemicals, and can use as little as 4 oz per acre (up to a quart for the cheaper ones), so you might be shocked at the outlay, esp. if you are only covering a few acres every year.

Some chemicals do require you pass a course & recieve a licence to spray, different states are slightly different on that. And you are liable, if a neighbor has a garden nearby, understand drift & all that. :)
