‘15 model 8240, feeder reverse has decided not to work for some obscure reason. 🤷🏻♂️
You can hit the reverse in the feeder switch, then push it forward, then hit minus on feeder speed button, but no reverse action happens.
I’ve looked for fuses ...... can’t find any. Is there some sort of solenoid that’s not clicking in?
Help & ideas appreciated.

Does the computer show that it's in reverse mode? You're getting the instructions on the screen about reversing? Does the feeder variable speed work in normal operation? Finally does the feeder calibration procedure run?

Feeder shows reverse on the screen but there’s obviously no RPM.
Doesn’t have variable speed feeder.
Feeder Calibration ....... good question. I’ll run it again & see if that has any affect.

Are you sure your feeder isn't variable speed? If you've got the plus/minus buttons to reverse the feeder house, don't those affect the feeder speed when you're running normally? And is the feeder operating at the same speed it used to? Depending on what head you have attached, the computer might lock out the variable speed and demand a certain feeder RPM. My FD75 does that. You could unhook the header cable and see if that changes the way it behaves. It's possible the hydraulic portion of the CVT isn't working. I am not sure how it is supposed to behave, whether at full speed the hydraulic motor is stopped, or turning forward a bit.

Ah yes .... good point. I'm thinking the "head selection" will define what you can & can't do insofar as feeder speed. It probably needs a corn head recognition module to make available the vari-speed option.
I'll do some more thinking.
And speaking of thinking ....... I recently did a "feeder calibration" & it may just be a coincidence ....... BUT ..... from my fogged up & sleep deprived harvest memory ....... after that is when the green stuff hit the fan!

My last CaseIH combines both had feeder switch failures, possibly that might be the issue?
Some bean counter decided they could get that switch from another supplier and there was widespread problems to the point nobody could even get replacements anymore, every unsold machine on the lots was raided for parts and they even figured out how to make a similar switch from an autoparts supplier work. Another example of penny-wise and pound-foolish...

Just unplugging the head should be enough. |

I wonder if there's a place in diagnostics to get a readout from the button itself. There might be. If so, then could easily determine if the button has failed. rod, when in reversing mode can you push the feederhouse forward with the + button? If so then that would point to the - side of the button failing. The feeder should go in either direction in reverse mode. |

Nah ...... no action either way. I’ll do the feeder calibration again & see if that changes anything .

Found the culprit....... Wires rubbed through because they were cable tied behind the connector against a steel hydraulic line! 🤷♂️   |

How did you manage to find that ?

How did you manage to find that ? By using 135cfm compressor to clean machine down after doing carrot seed ........ & it just popped! I looked all over the 🤬 thing for hours beforehand - trying to find the problem. |

....... & for those who don’t know about carrot seed harvesting, here’s a few pics.  .....nearly a bin full of carrot seed & trash above ....... & the spickey bearded bit in the blue circles below is the carrot seed. All this crap is graded by a specialist seed grader & we're left with about 25-30% of what you deliver is actual carrot seed. Then it’s purity & germination tested. There’s reasons why carrot seed & others are high priced. Because they’re temperamental bastards to grow!  |

I know nothing about growing carrot seed, but have heard that it takes two years for a carrot to produce seed, is that true? Just heard people talking about their gardens is where I heard that. Then do you harvest the vegetable after or is it past it's prime?

Then do you harvest the vegetable after or is it past it's prime? Carrots for seed, take about 10 months to grow & then harvest. The actual carrot root - the orange bit you would buy in the supermarket - is like a piece of wood by this time! |
