If you haven't already you might want to take a look at some of the boomless nozzle setups available . Can do a wide swath with just 2 nozzles set in the center of your track. And it puts it fairly high to get over the top of blackberry tangles.
I'm planning on a long range spray gun for the thickets. How well they work is another question. I'm replacing the pump with an identical 8 roller pump with an advertised 300psi max output.
Supposedly has a 35' range, but that's shooting a tight stream. Don't figure that's going to work too well...........use up 100 gallons in a heartbeat, and won't give good coverage. Zee plan is to use wind drift. We can have some high wind days in Oklahoma. A medium coarse spray will travel quite a distance in the wind.
One problem I see, is working from ground level, or at most.......from the tractor operator platform. It doesn't give good height for getting the most bang for the buck out of wind drift.
During the intervening years, while this mess was building up, I built this thing. Mostly for limbing trees.......but would have been handy to buy me a bit more height. Lord Knows when I'll get to rebuilding the motor for this, or the other, 190XT.
I could borrow a tractor with pallet forks to use this thing...........but the guy's one of K'kins bosses. I don't believe I want to do that. I've borrowed it twice, and I'm a nervous wreck until I deliver it back to him.
Anyways, for now, it has to be a spray gun at ground level I guess.
Guy at COOP says that he has a few business cards from drone outfits. I'll check them out when I pick up the Cimarron. I'm pretty sure there's a minimum charge for this kind of thing (spot spraying), but it doesn't hurt to ask.
The thing about using contractors....................it's money out the window. At the end of the day the money is gone, and if you need the service again.......it's more money. Spend money on your own equipment, you build equity(if you want to call it that). Spend on my sprayer, and I have the sprayer to use when I need it. This thing is going to be in stages. And it's probably not a one-and-done.
Speaking of contractors..................... I had a guy build fence...........at 2 times during the job, he upped the price, and said he'd walk if he didn't get it. You can't shoot the guy, that won't get the fence done, and it puts you on track to wearing orange. It's a lose lose.
Hired another guy to cut cedars...............took a full day to cut maybe 40-50 WITH A SAW LIKE I BOUGHT. Every time I went to check on him, the sucker was on his phone. Ran him off after one day. That little deal worked out to about $10 per tree.
My take on the situation.................... I believe a lot of these guys that start their own business around here are guys that don't like working for someone else........mainly because someone else requires them to ACTUALLY WORK. Or maybe I just had a run of bad luck.
K'kins probably woulda shot both of them (she was not happy), but it would be a shame to have to visit her at McCalester.
Be a lot of driving at $4/gal gas.
