    My 2009 Z spray had a Garmin Forerunner 100 GPS. If you left it on, it would eat a steady diet of batteries.

    They now install an aftermarket speedometer designed for motorcycles, ATV's, etc... It is made by a company called TrailTech. It runs off the power supply from the machine.

    I used a bicycle speedometer on my spreader. Cost about 16 dollars from Schwinn.
    See my old post from years ago. You have to put in the wheel circumference, when you first install it.
    I could also calculate average speed and maximum. It also includes a trip-meter; you can use that to calculate how many sqft you covered.
    Watch battery--lasts two years. The unit snaps off in case of wet weather.

    thanks for the replies,

    on the bicycle or motorcycle style, they all seem to utilize wheel sensors
    to monitor speed, i just dont see any way to attach these items, a fork sensor
    and the little magnet piece that goes on the wheel

    seems like a gps type would be better for this ?

    i downloaded a gps speed app onto an old ipod i have so ill try that for now,
    but i want something more perminant, i certainly dont want to have to charge or change batteries daily- i know i would nt keep up with that

    So true--no spokes to attach the magnet. I put the pickup on the frame near the wheel.
    I used a magnet glued to the tire with rubber cement. It took a couple tries to get the north and south pole right. Then it was fine. Use silicone if you need to.
    My speed was usually about 2.6 mph.

    thanks riggle,

    i actually put one of those on my bicycle couple years back and it works good.

    and its cheap enough to try any ways. dont know about glueing the magnet on, i predict with the amount of abuse ride-on tires take it will fall off
    pretty quick and be lost, we'll see

    I used rubber cement to hold a magnet on the wheel of my push spreader. Silicone tub sealer would probably also work. Mine lasted at least 3 years. If you lose a magnet--just glue on another one.
    On my Permagreen--I had trouble finding a place to mount the "pickup". Looked like I would have to drill a hole in the base and put in a small bolt.

    Keep in mind--I put a brake light switch from an old car on mine. It allowed me to use it to calculate the sqft I covered.
    I found the link.

    riggle if the switch could be coupled to the hopper turn on or sprayer turn
    that would be pretty cool.

    anyhow, i was searching for the schwinn speedo online last night and found something else, im gonna give a try 1st, its got a 12 v power supply so i can hard wire it in, and its got a battery so i can remove it to use on other equipment if needed

    ill post back how it works out when i recieve it,
    my ipod app thing didnt work, so i tried on an iphone it works ok,
    but im not gona spray with my cell phone attached to sprayer lol

    This should be interesting. I hope it is suitable for low speeds. Remember I averaged about 2.6 mph.
    Using the trip meter you can find the approximate sqft covered if your swath width is consistent. Just remember to start the trip meter when you start spreading and switch it off when done. Or adapt a mechanical switch.
