I had the same issue. I posted in this thread and it was resolved - www.acmoc.org/bb/discussion-d72/31498-no...ech-section?start=20

Captain Beans: It looks like you are a "member" instead of "user" now, so you should be good to go. I will message an administrator to make sure you have full access. JM

Some updates so I bought 2 heavy duty batteries and the operators manual! Tomorrow is the big day where I finally start destroying the spiny brush that has encroached my grandfathers pastures! It’s mostly coyotillo or tullidora (karwinskia humboldtiana), granjeno (celtis pallida), panalero (schaefferia cuneifolia), crucero (randia aculeata) and huisache and mesquite (acacia farnesiana and prosopis glandulosa) but these last two I have to spray them first with triclopyr picloram and clopyralid I have been fighting these stupid shrubs for 7 years!  

Save those peppers! I hope the re-prints you purchased are legible. Mine for a U series D4 was decent, but I just opened one up for my Allis Chalmers HD6E, and the photos are terrible. Some manual is better than none. Excuse my ignorance, as I have never taken an applicators test here, but what are the common street names of the herbicides you are using? Our tenant farmers sometimes use a 3x tank mix of some pretty potent stuff; literally see weeds and brush wilt within hours, not days!
I will guess that you will be needing a brush rake next, to make piling the brush easier. Enjoy. JM

I am anxious to see how your disc does on the brush. I built a pin on brush rake for D4. It was good for uprooting and piling mature brush but skipped over and left behind small stuff. I am afraid it just encouraged it. I have seen videos on what those Rome discs with 32" blades can do.

So here in Mexico you dont need an aplicators test but the herbicides avaiable are getting more and more limited.

Tirclopyr is supposed to be sold under the brandname garlon 4 like in the USA but for the last 5 years its out of stock everywhere and there is a herbicide mix called togar max that contains a tiny amount of triclopyr, aminopyralid and a lot of solvents adherents, etc.

Clopyralid which is the only thing that works for distrubed mesquite that resprouts with many twisted branches (because its applied to the leaves with a sprayer) is not sold comercially here in Mexico but I bought 2 liter bottles online in the USA delivered to my mailbox in hidalgo texas and hid them in my moms purse one at a time (mexican style ahahaha but she consented to this lol).

Picloram was sold as tordon here in a mix with 24d amine, but thats being phased out and aminopyralid is replacing picloram but you can still find picloram tordon under generic names, this is very useful for huisache (which without herbicides its the toughest to erradicate mechanically because the taproot is very deep deeper than mesquite) you just spraye the leaves and the shrub dies in like 6 months.

For all the other spiny shrub (non mesquite, non huisache) you can use tebuthiuron pellets for soil treatment (spike) but thats also not available here in mexico since the 90s apparently and it takes a long time to work like 18 to 24 months to kill the plants, it is very useful for randia aculeata because randia is very difficult to pull out of the ground it grows the roots down AND to the sides and roots are very tough. so if you miss some of the lateral roots the damn thing resprouts.

My father hired a backhoe to clear some of the pastures some 10 years ago but the randias are 8 feet tall again, the soil is very deep but its calcaerous the surface is incrusted (like an adobe) because of some sort of chemical reaction with the calcium and the clay and the intense heat its basically like the land is cooking into a huge brick every year, and all the thorns and holes in the ground that were laeft from the backhoe's lousy job made it impossible fora regular tractor to till the land to break the crust so thats the idea of why I got the d4.

Where are you all from?

Capitan: I am from Northern California, near Sacramento, CA. My family has been involved in farming here since the 50's; My brother has been retired full time for 10 years now, but we still drive around the fields to be thankful we do not have to be the ones doing the hard work anymore!
Yes, GARLON is a great product for killing berry vines here (and expensive) my sources tell me there is another product now that works even better at less cost.
Surprisingly, RM43? from the local hardware store or via Amazon works pretty well.
Too bad you can't use your disk to make a firebreak and light up some of that brush.
I have a custom disk that our friend Mr. D4e sold me; very similar build, except it folds and uses SWECO components I believe. JM

tryclopyr picloram and aminopyralid is known as grazon extra. a product of of dow agroscience (now corteva). the companies often change names to stop them being sued(in australia for example commercial quantities of round up brand glyphosate is sold by nufarm agro chemicals not monsanto domestic quantities are a different company again)

point is many products are different ratio mixes of the same actives. some are the same chemical just in a different form. such as 2,4-d ester or amine and then you have the low volatile formulations too. (very important for 2,4-d as it can drift long distances nasa recorded a drift of 700km for 2,4-d several years ago)

always look at the active constituent, the compound type i.e is it ester or amine etc) and the chemical group to compare apples with apples (it also helps you find the generic product that is often a third the price) and it also helps with resistance prevention and management. a group b herbicide works the same way to kill a plant but a group m product works differently so if your getting issues with a group b product a group m might be the choice.

and this is something that many people don't realise you have to apply the right product at the right time using the right method so the plant is at the right life cycle to uptake the product and for it to work properly and get a good kill. locally april to june is the time to spray lantana with grazon yet september to december is the time to spray it with methylsulphuron. most products say to spray when the target is actively growing.

also if the plant is too small or too big it wont work. same if the plant is under stress such as drought or if it has been too wet.

most state dept of agriculture will have data sheets for the economic and environmentally impacting weeds in your state. go on their website to access them for free. you can also get them in hard copy from any of their service centres. the chemical companies also publish a lot of info too dow agroscience for instance has the woody weeds guide. if their is a landcare association near you they can be a great source too.

source I'm a licenced ag spray applicator.

wow ok thanks, i am not licensed because mexico is a huge dumpster (except for grandpas ranch which i love) with no laws, i bought a book about herbicides some 7 years ago or so called woody plants and woody plant management by rodney bovey. It helped understand the complexities of herbicide use mainly why sometimes herbicides dont work. I have made many experiments with herbicides here in this part of the world (which is called tamaulipan mezquital), you are right that the time of the year to apply herbicides is when the plant is storing energy, not when the plant is putting on new growth because of the flow of the nutrients broadly speaking, but i also realized that you have to do the experiments yourself and see what works and what wont work, but I have succesfuly killed mesquite and huisache foliar spray with .5% triclopyr .5% clopyralid .5% picloram and i use a stihl gas engine backpack mist sprayer and it works well especially because i hate pumping the backpack sprayers with my arm and the damn sprayers are getting more and more flimsy made in mexico type of quality hahaha I am mexican but i hate it here sometimes

I managed to advance 3 feet or so with the dozer i wasnt able to steer to the sides because i am afraid the dozer will start moving out of control and run over my corral, but i will try again on sunday!
