New Holland 411 Discbine problem

BOL has 411 discbine that quit cutting yesterday. You can hold PTO shaft and turn disc cutters. We suspect a problem in shaft from main gear box to cutter bar. Probably have to drop cutter bar to fix. Has anyone here experienced this? How bad a job is it to drop cutter bar?
 
I don't know about NH, but my JD1460 did something similiar last year; it was the 'driver' between the gearbox and cutter bar. It wasn't cheap, but really not a bad repair. Just a bit tough to get to, and the coupling rubbers were just a bit pricey.
 
OH boy! YES! I bought one of those when it was only 2 years old. A trade in on a bigger hydra swing. I got it home,thought it was awful loud,cut for an hour and a half and it quit. There was a bearing out in the shaft from the gear box to the cutterbar. Ruined the shaft. The dealer said he'd stand behind it,said he should have checked it over better before he sold it.
Took him 10 days to fix it. I used it five days and it got loud and quit again. Mostly quit again that is. The first cutter disc would turn,the rest wouldn't. Apparently some pieces got down in the cutter bar and took some gears out down there.
I told him to keep it that time. He let me take a new Hesston 1120 conventional for just the cost if shipping and setup on it,even trade otherwise.
Ended my desire to have another discbine.
 
The NH 411 machine can be real problem units. I used to get quite a few in on trade and half of them had serious troubles. I finally quit trading them in. They can be real costly to repair.
 
Ya,I gave $9000 for the one I bought. A month after I took it back,he had it advertised for $10,900. So I figured it wasn't cheap to fix.
 
I forget now which bar the 411 has.... but I don't think you would need to drop the bar to fix a shaft problem above it. FInd out if the problem is in the shaft drive line or the gear box above the bar... or in the shaft between the bar and gearbox. I've had the drive splines go bad on that drop shaft on my Deere. It's an expensive annoyance to repair. Also make sure the gearbox is appropriately attached above it...

I would strongly disagree after what happened to that one I had. That has that continuous gear drive with one running off another all the way across. I would completely disassemble that bar,flush everything out thoroughly,then go over it very carefully with a good strong magnet and try to find every little bit of shrapnel that might have found it's way down there. If not,you'll be tearing it all apart and doing even more major repair to it after just a few hours running.
 
I'm not even talking about opening the bar and I doubt the problem is in the bar. It's somewhere in the driveline to the bar...

I've only ever drained a bar once and never cleaned one. My Deere shits a module or two every year either due to a broken shaft or a bad bearing. I just refill with oil and keep going since this bar was leaking...

Again, I'm not sure if the 411 has the modular Kuhn FC bar or the older Kuhn GMD bar that needs complete disassembly... but I find little need to do much cleaning on the FC unless there's been a major catastrophe like gears losing teeth.

I'm thinking if you pull that shaft out of that housing,if there are any pieces in between the shaft and housing,they can drop in to the cutter bar.
Not trying to be a smart alec,but after what happened to that one I had,I'm thinking it's probable.
 
I dunno. On the Deere the bars are sealed from that drive so there's no worries. It's all external parts. The NH... I really don't know if it's sealed or not. If it isn't then yes, the chance is there that pieces could drop I suppose...

so guys, I recently bought a NI 5209. How does it compare in reliability with the JD and NH types?Mine has a new shaft, I replaced 1 disc drive bearing and checked the rest. All good.
 

I would start off looking in the bevel gear box, and see where the rotation is not making it through. I would not drop the header unless I could see that the vertical drive shaft down to the bar is turning. The right end drops with just four bolts just under the cover, the left end would be more complicated. I don't know how pieces would get from the bevel box down to the cutter gearbox. There is a seal at the bottom of the bevel box to hold the oil in.
 
I bought a NH 411 a couple years ago cheap.The first time I went to my dealer for parts he told me to get rid of the thing,he didn't care if I bought another brand but sell that thing and the farther away from him the better.He said they are way overpriced to work on and poorly built machines.I still have it but the first major problem and it goes to scrap.
 
In our area, the 3309/5209 seem to be the longest lasting discbines. Even with an abusive operator they seem to be cost effective to repair.

I've got a old one I picked up cheap to fix up, haven't got to it yet. Still running my Pottinger 10 ft'er.
 
yes I have a new Holland 411 discbine and the pto shaft turns but the main long shaft does not and suggestions
