mt5000 spray control

I was wondering what the speed range a Micro-Trak 5000 is. We seem to have a speed range of 2-2.5 mph when using it on our sprayer. Is this all of the speed variance we can achieve? If not, what are some things that can be causing this lack of variance?

Here is a link to a operators manual for the controller. You should be getting a wider speed range. Do you have plenty of pump capacity and flow?? If either is low then the controller will not be able work correctly.

Is the monitor counting feet OK? 5280 feet when driven a mile? Ground wheel speed sensor or radar or GPS? Flow meter calibration # OK? valve calibration # OK? What kind of pressure can you get it up to when you are sitting still with the monitor switched to manual? Just went through the whole nine yards with my Raven after I switched from wheel sensor to GPS. Neighbor was asking me why I was driving the sprayer up and down the road repeatedly. Jim

Yes I have all the capacity I need with the hydraulic pump. I have 1.5 inch feed line to the pump, 1 inch line to the valves, 1 inch to the agitation, but only 3/4 return line that I am going to change to a bigger line, I only have a 25 pound range so I thougt with going to a bigger bypass, return line it will probably help give me more range. I just am not sure how much range they are designed to have. Thanks again

Magnetic pickup off the wheel for the distance. I may not have the distance dead on, but will that affect my pressure ranges? We have Raven on our anhydrous applicator, and that is sweet.

To provide speed control of a pnumatic cylinder,
or motor, you put a flow control,(needle valve),
on the exhaust, as a piston with pressure on one side, can only move as fast as exhaust can get
out the other side.In a hydraulic woodsplitter,
hoses must be sized so as not to restrict the
exhaust flow from returning to tank, as that
would cause backpressure and slow cylinder speed.
an undersize return line can restrict speed.

The distance calibration would have to be way way off to cause your symptoms. When I changed mine to GPS the monitor told me the tractor was going 65 MPH! That would definitely throw things off! Usually too small of a bypass would prevent you from getting the pressure down far enough, in theory. If you have a separate agitation line along with the bypass hose you should have enough pressure relief between the two. I don't know, I'm just throwing out ideas. Is the controller valve working right? Something tells me you have something electronic going on that's not right. It's probably embarrasingly simple. Wrong wires hooked up? Jim

Verify that your regulating valve is opening and closing all the way by switching it to manual operation and increasing/decreasing the pressure all the way in both directions. You should be able to run the pressure up well past what you usually spray at. I had a problem last year with a bad valve on our raven system. It would work in a narrow speed range but would not adjust to changes in speed. Also maybe check your filters for obstructions... besides what others have said, nothing else comes to mind except maybe a computer problem.
Good Luck,
LonM
