BX23 dandelion killer

Bernie - looks great! Is that a quick-coupler on the hose line to the boom? I'd be curious where you found that, particularly if it has an internal diaphram to stop flow when disconnected. Also, do you have any problems with your pump when reducing nozzle pressure by closing your in-line shut-off slightly? Thanks.

BernieP, that is a good looking setup(and a good looking lawn

. Great idea using the bicycle speedo. I was using a stopwatch to time a paintmark on my tire to set a speed I calculated based on tire diameter, but since the speed changes with terrain, I have to keep checking it and adjusting. Your way looks far less difficult to work with

I have basically the same 25 gallon Fimco sprayer except mine has a "Y" gate to control spray pressure by allowing you to send excess pressure back to the tank. This "Y" also allows you to mix the tank contents with the pump. So far I have kept it in the trailer behind the garden tractor. I am going to put it on it's own smaller cart so it is a little easier to maneuver in tow. I use mine with a 2 nozzel boom kit also from Fimco that has 80" coverage. I am planning to add a third nozzel to get 120" as the pump will handle it. Where did you get your spray boom/nozzels and how wide is the coverage?

On the speed and calibration issue, I use a handheld GPS to calibrate for speed. Works great.

On the bicycle speedo: It is programable in millimeters traveled per revolution of the bicycle tire. What I did was hang a plumb bob off the tractor, rotate the drive shaft one turn and note the distance traveled. 137 mm if I remember right. Now again if I remember right this thing was set from the factory for around 2200 mm, so you can see it is going to get a pulse from the sensor much more frequently in my application than on a bicycle and the little computer can't keep up past about 4mph

that is a brass quick coupler made for garden hose, there is also a male coupler attached to the top left of the frame so I can click it on there when the boom is off. I found some adaptors at tractor supply that have a barb end for the hose and a threaded end that match hose end threads, no check valve. With 4 nozzles I get 20 psi so I haven't needed to reduce nozzle pressure.

That lawn is not that good when you walk over it and look down/forums/images/graemlins/grin.gif
I saw that tank at Tractor Supply( or one of those stores around here I have been to all of them lately) That would be a nice setup
I just stick the boom hose into the tank to mix.
The tank just came with a wand and pump and I built the boom and plumbing myself with parts from Tractor Supply. It would have been cheaper to buy a boom setup but they didn't have them when I bought this tank except the ones that came with a trailer. The boom is a little more than 6 feet because thats how long the square tubing was /forums/images/graemlins/grin.gif The nozzles ended up about 24 inches apart. I wanted to be able to keep it relatively close to the ground to help keep the drift under control. I was thinking about building a new folding boom and upgrading the pump but it seems to work fine as is. the dandelions are dying as well as some of the other broadleaf weeds in the yard. I have something that looks like ivy except without the vine growing all over and the tramec899 didn't seem to touch it.

Wow thanks, that's the excuse I have been looking for.
What brand/ model do you use?
