So I talked to the dealer techs and they said it isn't making any noise. They fixed the scored cylinder on the rock shaft. We shall see. They said the hydro pump was within specs. Time will tell!
Did they say why the cylinder was scored and if it was bad enough to cause further issues? I searched the rock shaft and found a few posts about it, accompanied by pictures of metal debris.
So when they first delivered my tractor I checked the hydraulic oil and to my surprise it was bright green and foamy as hell. The hydro was so jerky it was uncontrollable. The fuel tank leaked all over my shop floor. The rock shaft didn't have full range. The 3RD SCV wouldn't bleed off pressure. So they recalibrated all those things, changed out the utility pump and I had them to drain the fluid and change the hydro filter. They didn't say why the piston and rock shaft was scored. My front drive shaft sleve had gotten warm enough down by the pinion bearing that it deformed and it was broke in three places. So maybe with the new front end and rock shaft fixed it will be ok. When they bring it back I will put the rotary cutter on and see. Oh and one more issue, I was back in the field mowing with a sicklebar mower, put the range selecter in neutral to let it run while out of the seat, got back in the tractor tried to put it in gear and the linkage fell off! But even after all of these problems I still like this tractor.
The foaming could have caused all kinds of issues. I hope it's all sorted out and no further problems happen. The dealer stated the tractor is lifting total capacity, and mine is rated for 1500 lbs with the forklift attached. He did say the manifold was dry-rotted and would be replaced under warranty. I'm not sure how that could even happen in such a short time. I sent them this video, but they said my tractor would not lift it. I told him I bought it based on videos of users picking a ton of pellets, and he said it was impossible and I needed to buy a 5s.
At practically idle speed as well, the one in the video has a healthy hydraulic pump. According to the specs in tractordata, which has 3 loaders for some reason, any of them should be able to lift a 2000lb pallet with the lift arms, with not with much capacity left, or more easily with the curl function. I wonder why the fluid is foaming? Wrong fluid or overfilled?
Mine is the 440r, so I can't understand where the 1500 lbs comes from per the dealer. I will measure the height from which I tried lifting.
The pallet is 48 inches; I only need to lift it to 48 1/2 to 49 inches.
My best guess is it was a form of contamination, as they are all designed to negate that issue from the factory. But it's so hard to say how that would occur.
I guess your machine has a separate HST filter too? Odd noises when moving and lower hydraulic pressure, maybe the HST has been fed foamy oil too? Probably not a big deal for a little bit if you haven't been working it hard? I think the hst is most sensitive part to bad fluid, but I'm not a mechanic. There are a couple hydraulic pressure ports on a HST and I would ask them to take a reading on the charge pressure and high pressure relief, just to make sure the HST is fine, and maybe do a slippage and power test on a steep hill when you get it home. A new tractor shouldn't creep much at all with the hst in "neutral" in Low or Mid range on a steep hill with no brakes, and in mid range, the hst should push the tractor up a hill you are worried about going over backwards on.
So Kromc5 did you get your tractor back, mine is still at the dealer really need it, my x758 is taking up the slack lol! It's a shame you can't buy a tractor and depend on it.
And that's exactly the height where the loader has the lowest lift capacity.
So after mowing for 3 hours and driving down the road, no noticable noise but the draft arms still won't go down without an implement on them. Annoying!
We use a pellet stove for supplemental heat.
That does not make much sense; I would question the timeframe for breaking in. I sat in JD's on the lot with just a couple of hours, and they were functioning.
I agree Kromc5, would like to get in touch with John Deere. How did you contact JD CCMS or who did you contact for them to get back with you. Maybe John Deere can give them so training on this. Thanks John
I filed a case number on the leading site but will send you the email address.
Thank you
