Took a new New Holland Discbine to a gent this afternoon. He now has two and makes a lot of hay for both himself, and neighboring farmers. Traded in an older New Holland Haybine. The older unit has been pulled a few hours by my 185 diesel tractor. He replaced it with a new New Holland tractor last year as engine was needing freshend up and I liked it so was priced fair to me.

Have the discbine’s improved over the years? They were just coming onto the market when I transitioned from a farmhand, to a business owner. I recall a couple of the biggest complaints about them at the time was they required a lot more horsepower to operate effectively, and the ‘sheared off’ alfalfa took a week to ten days longer to sprout back, vs the ‘clean cut’ of a sickle bar haybine.

I tried to follow the science, but it was not there. I then followed the money, and that’s where I found the science.

While I cannot say with definitive answers, I would have to say "yes" given the amount they sell in comparison to the old sickle bar style. I have no direct experience myself of usage; only repair from damage. I will ask about power requirements and results of processing till "sprout" back. I have only heard from farmers they really like them, and I don't think any have been complaint ridden. The same gent has purchased a new accumulator, and square baler also to go with the round baler purchased a couple years back. I gather he likes the New Holland offerings citing much of what has been purchased new is that brand.
The party I delivered this newest unit to has a mixture of farm equipment. Some New Holland, some A-C, and of course some John Deere.
I have heard these things are a bit on the expensive side but again, I really don't know.e

A discbine can take a tremendous amount of horsepower depending on the material going thru it especially if it has the flails instead of rollers we had both in years past
Had a 489 new holland conditioner years ago and got into some secondary growth hay that it wouldn’t cut thru even with the stub nosed guards the hay was so thick we were pulling it with a 185 cousin had just purchased a JD discbine said he’d bring it over and cut it for us was pulling it with a 1066 so we put the 185 to it and it made that 185 grunt
We ended up purchasing one with rollers and another with flails the flail one pulled harder and in thick hay and 1000 rpm pto it made our 7010 holler

They pull hard in thick, down and tangled tall grass hay with lots of under-growth. Not so much if the crop is standing well. Been mowing with my 200 and JD 530 discbine (9'9" cut) with rollers and sometimes it's all it wants on a hot day with the AC running. The direction the hay is leaning can make a significant difference on how hard it pulls. The "Re-growth" theory was started by New Holland back when disc mowers/Discbines first hit the market (70's-80's?) because they were drastically hurting sales of their Haybines and NH had no disc cutters at the time. In the following years, several Universities conducted trials and found that re-growth was basically the same. 3 weeks ago, we mowed 20 acres of alfalfa with the discbine and NH 2450 swather (sickle type) in the same field and today the re-growth looks identical. That's my thoughts for what's it's worth.

Sharp blades help and the correct cutting height matters. Especially in grass because you are able to cut low with them but grass prefers a few inches of stubble. If concerned with regrowth it helps to limit wheel traffic and remove the crop as soon as possible.

My brother runs a New Holland HW365 with a 15' 416 header, 225hp or 15hp per foot. Yes, it burns through the fuel but will also cut 15 acres an hour in heavy grass. It has a quick change on the knives, uses a special tool to push down a spring clip on the rotor. Blades are reversible, and usually get either reversed or changed every 100 acres or so. When the self propelled disc mowers first started showing up in our area alfalfa growers didn't like them because the would leave strips in lighter cuttings, but that doesn't seem to be an issue now, possibly because it is so much easier to keep fresh cutting surfaces on the machine.

If you push all the hay through it that the machine will take, you’ll be needing horsepower on a width to width comparison to a sickle bar mower. A guy can usually back down a gear and get by just fine. If you leave the blades on forever and a day you don’t get the best cut but I’ve never seen an issue with regrowth.
All things considered, I would NEVER go back to a sickle bar mower.

It’s all about speed these days, mow faster and cover more ground with a disc mower with sharp knives. I have seen farmers pushing the limits by running too fast. That causes skips, crop damage, and tearing of the crop versus a clean cut. We ran a AC 390 up until last year, sickle mower and conditioner also. Started having issues finding parts so we stumbled upon a nice used MoCo. We run the shoes all the way down to keep a 3”-4” stem. Speed is determined by the crop density not by having a huge hp tractor to over compensate. That’s hard on the disc mower which will lead to damage and also damages the crop. I don’t see a regrowth difference between sickle and disc mower.
