BX23 dandelion killer

[Berniep]

Got my sprayer out last weekend so I thought I would post a few pics in case anyone else is interested in doing this.
I Made an atv sprayer into a pull behind sprayer in a utility trailer to be pulled behind my lawnmower.
Then I got my BX so I decided to build a 3ph carrier for it.
Here is the frame made from some old chain link fence posts and scrap metal I had laying around. The only thing I had to buy for the frame was the pins.

Here are a few pics of the sprayer setup.

Now to properly calibrate a sprayer you need to be able to duplicate ground speed. I have a little bottle thingy that I hang under a nozzle and drive a specified distance and it gives me gallons per acre. A tachometer would be best but I don't have one yet and I was walking through Wal-mart one day and saw a 10 dollar elecronic bicycle speedometer and thought that I could get it to work.

I put the magnet around the front drive shaft and the sensor is attached to the skid plate.
It only works to 4mph or so because the little computer in it is not made to update so fast. And it tends to get out of alignment pretty easy. But it served its pourpose.

Great job!

If I were doing it, I'd add a deal to allow stands at four corners, and you could sit it down easier, but it looks great as is!

Other thought: Tiny Tac--I put one of my 2200. Works Great and was $60 (IIRC). You might have to do some ciphering to match ground speed w/ engine speed, but you could easily do low range/full pedal forward at different RPMs to have a good idea of ground speed.

Hope this helps.

A car tach from the auto parts store like AutoZone sells for about $25-$30. It'll have it's own housing, mounting brackets and only two wires to hook up /forums/images/graemlins/wink.gif.

Yeah I want to get a tiny tach for it. You are right I just need repeatable settings.
I would set an rpm for full pedal travel in low range.

The tachs at auto supply houses won't work(wish they would) they need an ignition system which I don't have on this diesel engine.

I was going to put some casters on it or maybe a coulpe of runners but it's very light and I haven't had a need to remove it when its full

I tried a bicycle speedometer on my dirt bike. The vibration from the motor was too much for it and made it inaccurate. Most are adjustible for wheel size but you'd have to try different settings to get it accurate seeing you have a differential to contend with.
