Big Ben - 12/25/2022 20:35 booms are steadier despite being 10’ longer.
That is a function of width not boom design..


The booms on our R4045 and R4060 followed the ground better especially when turning compared to our older sprayers. Funny part was they were EXCATLY the same width.  120ft 

Talking about boom width and IT'S effect on stability, not boom height control systems.



Ok.  The boom on the R series is steadier and more stable than the older sprayers especially when turning.  Does that do for you??  How many R series have you run?  How many acres??

I have not run any but I understand physics. There is a reason that a tight rope walker uses a 30 foot balance pole rather than a 6 foot one. As far as acres go, I do +- 60,000 acres per year with a 4830, 1 sprayer, 1 operator, two water trucks. Sprayer bought new in 2012 has 650,000 acres on it and has run 100'(one season), 120' (one season) and 125' booms (8 seasons and counting). Exact same machine, different boom lengths, no auto boom height. The wider you go, the more stable they are. Physics.


So explain then how an R series has a more stable boom then a 30 series when both are the same width.  


Better auto boom height control. Be that as it may, my main point is that physics dictates that the wider you go, the steadier they will get. However, I will concede that I misspoke when I suggested that design and construction "has nothing to do with it". Case in point is the JD Carbon fibre boom. Even at considerable width, and likely BECAUSE of the considerable width, they are the most unstable boom I have seen on any sprayer. No, I have never run a set but I have watched them going up and down the fields a LOT and they look like an albatross trying to take flight. In a world where we want to keep the distance from nozzle to ground as consistent as possible, JD comes out with a boom that will wave its tips up and down what appears to be 5' or more on flat ground. Meanwhile, the Europeans are making booms that articulate up and down at points down the boom so it can hug the ground OVER a mound or terrance ledge or up a sloped draw. At any rate, my point was and still is, the wider one goes the more stable the booms get (all other tings being similar) but I will correct my first post by adding that there are some things that can be done to make minor differences or in the case of carbon fibre booms and major difference in the wrong direction.
