    Looking for the forward speed on a Kubota 4310 HST with 21.5x16.5 tires on it. I have found a couple of sites that give me a speed but I think the tires are not as big.

    We have a Deere 1250 with the same tire make up, that would be my other option. I know I have seen at other courses I was at that Deere has a chart to help convert and find the speed with different tires, I just have to find our manual if it's still around.

    We need to know the speed for spreading fertilizer.

    Thanks, Mel

    Do you have the tractor or are you looking to buy one? If you have the tractor find someone with a portable automotive gps unit or one on their cell phone and go for a ride. The gps unit will tell you how fast you are going.

    Thanks Jack,

    Yes we are trying to find how fast it goes. We have it from one of our other courses doing deep tine and thought maybe while it's here we could fertilize with it.

    Mel,

    The most accurate way would be to do some time trials. Find a straight 200 or 300 feet and time it. You can find a conversion template by Googling " timed distance to miles per hour". Should only take a few minutes

    Mel,

    Nothing against Jack's GPS suggestion, but my portable GPS seems to update only every 15 seconds or so. I'm with Sam, only because you and your guys should always remember the basics, by going way back in time.

    First of all, determine the speed that you can safely navigate your course. That may be 6 mph, or 3 mph. I don't know your course. But that is the MOST important information that you need. The safest speed that you can navigate your course.

    Then.....find a section of road where you can mark off at least 500 feet. The longer the better. But let's assume 500 feet. Does your watch have a timer on it, or better yet, can you get a true stop watch? Once you've timed that distance....and found your true ground speed, (forget the damn manuals) write down the RPMs, low-high, which gear, the color of your socks, at FULL foot pedal. Then repeat, and repeat, until you ascertain your desired speed. Change gears, change engine RPMs, whatever....but find that 3, 5, or 6 mph speed you're looking for.

    But if everything fails on you, including that cute knob to lock down your accelerator pedal, you'll now have a book that will tell you that at such and such a gear, with your engine cranked to say, 2000 RPM, with the accelerator all the way to the floor.....you will know your ground speed is what you want. And all your operator needs to do is get the gears in the right position, the engine racing at the correct speed.....and make sure he keeps that "pedal to the metal".....at ALL times.

    I like setting up my transmission gears, setting my engine speed, and keeping my boot to the floor at ALL times. If one of your guys says his leg is getting tired, then he's trying to push the pedal through the floorboard, and is probably on meth. The amount of pressure required to put that pedal to the floor is nothing.

    Man, I'm getting goose bumps. I love calibrating sprayers, and tractors, and spreaders, and other stuff.

    Are you sure you don't want me to fly there and lend you a hand? My Gulfstream G280 is full of fuel. (You should really check out their website. She's sweet.) I just need to know where to land. If the airport is more than 200 miles away, I would expect to be provided with nothing less than a '68 VW bus. If it breaks down, I can pull the engine and rebuild it on the side of the road. I've only done that 11 times.

    Thanks Sam and Jeff, we did the time trials and got the machine dialed in for our needs. We did choose the 500 foot track.

    Jeff we are only six miles from the airport, so the VW bus shouldn't break down to many times.....We see one in our neighborhood, might have to check with them to see if it's running.

    Thanks for all the suggestions.
