JD F441m monitor fault

Agri Spec Solicitor · Jul 1, 2023

We have a 2018 baler with the basic monitor.
It intermittently just turns itself off, and so the first you know is a lot of grumbling as a supersize bale is created. It has to be dumped and then rebaled, or if I notice it earlier I just turn the monitor back on and manually wrap. It happened 3 times over 11 acres.
I think it has been like this since we purchased, but I was blaming myself for not operating it correctly.
We had the supplier to it last year but it performed well over half an hour operating it.
Tractor same age so not thinking it is to blame with intermittent electric supply. Other monitors are ok.
I am thinking along lines of:
1. Monitor to David King. If no fault then
2.Renew harness from monitor to the baler

I wondered if anyone else has had a similar problem and found a solution? These intermittent electrical problems are a nightmare.
Thanks in anticipation.

I had similar on a 575, eventually discovered the spade connection had pulled off inside the D plug.

As above, open up the D plug and check the connections. People pull the cable when unplugging and it pulls the terminals off the spades.

Thanks for that: start with the easy though not so obvious fixes.
A job for later on today.

Turns out the D coupler is ok and there is JD advice about the netting process taking a lot of current and causing the problem. My O level physics doesn’t follow that but end point is we are getting a D coupler on tractor wired direct to the battery.

Only just seen this thread but this is what id have advised you to check, alot of balers and things have electric rams on them which require a fair bit of power so needs decent sized wires taken straight off the battery to avoid problems.

We are now waiting for some harvest weather to test the theory.
The D coupler going to the battery is installed after we obtained a proper harness. Routed tidily so it looks like it was done on purpose.

I'm sure that will sort it. I friend I used to bale for bought himself a John deere 580 I think, with that sort of monitor on it. Maybe he felt a bit awkward about it I don't know, but after a season I asked him how he had got on, and the story of all the problems he had with it came out. The guy he bought it off came out to see it and ended up saying he'd take it back, they had the dealer out a couple of times a still couldn't sort it. Having worked on a place with several jd balers over the years I remembered the service guy saying they needed a good power supply and they would fit a harness on the baler tractors if they were changed. So I asked my friend if he had a good power supply and he said he wished he'd asked me in the first place as the first couple of fitters to visit had never been to balers, it was the third one that put a harness on and it had been good since.

We finally did some more baling yesterday and over 20 acres we had no power issues so I am fairly sure the suggested fix was spot on. Just to make up for it we had plenty other problems caused by a dodgy sensor on the net roller. The most miserable day’s baling ever, netting each bale one revolution at a time whilst a screaming beeper kept telling me what I already knew

and used a lot of net.
Parts came today. Back to normal at last.
