New Holland Haybine Roller Question

I've seen a goodly number of New Holland haybines with rollers cracked and with rubber chunks missing. Was looking at a haybine yesterday and noticed the top roller especially and bottom roller to a lesser degree is exposed to rain and sun. FWIW, the rubber roller on my Hesston 1110 sets under a piece of sheet metal, out of the sun/elements. I've always thought maybe the chunks of rubber were from obstacles, i.e. rocks going through the rollers. I've also been taught that plastic/rubber and the sun don't mix. Sooner or later there's going to be hardening and with it inflexibility and from there cracking.

Is it possible haybine rollers crack, delaminate and loose chunks of rubber from to much sun?

Anyone have an older New Holland haybine that forever sets out, uncovered, in the sun and even after hard use, some rocks passing through and 365 days of sun, the rollers are still intact?

Just curious.

Thanks,
Bill
 
Have a 490 doesn't look like it has ever seen a shed. Rollers have a few cracks but no chunks missing, or separating. I did manage to run a few elm tree stumps through it in one field. Rollers still look fine
Sounds awful when it hits the back of the machine. This is in Colorado, where we have more sun then clouds.
 

I had a NH 411 with rubber rolls for about 10 years. It always sat out but the sun could get at the rolls only if the sun were low in the sky and the mower was parked just right. I am certain that the cuts in mine came from woodchuck holes. You always have a good idea about where they are and you can raise the mower to go over them, but there are still going to be some new ones. The sharp edged stones will cut the rubber. I checked mine periodically for embedded stones and dug them out. I would also pry larger cuts open a little and drip a little rust converter in there to kill the rust and slow the delamination. Even when cut it takes a long time for any pieces to come off.
 
Weather and sun is not good for any rubber material. But I believe that some of the rolls on New Hollands have bad batches of rubber. I have seen newer 472's with cracked rubber missing large pieces, that have been in the shed most of the year. Also seen older 477's that have never seen a shed and the rolls were perfect. Same with the 9 ft models. Either way they not any good once the rubber has started to come off. And its too expensive to replace to rollers.
 
I've seen later model discbines missing rubber too.

I'm thinking the only (subject to a change of mine - like the weather) senario I would change the rollers would be if I had a new or like new haybine that I knew 100% of its history and knowing first hand the condition of the haybine, how it was serviced/maintained from the get-go, would I consider the expense of new rollers.
 
So the bottom roller can high center on a woodchuck hole? The rollers on my Hesston 1110 are way off the ground, don't think that could
happen. Now the cutter bar could slice off the top of a woodchuck hole or get under a stick or worse log and the reel sweep that stuff into the
rollers. Now that I think of it, the 488 haybine I was looking at yesterday was very low profile, much shorter in height than my Hesston.

I know Hesston offered a center shoe kit for their cutterbar, don't know if that's available for the 9ft 488.

No, it isn't that the roll touches the ground, it is that the knives (discbine) will be hitting the stones and a few will kick up and be carried with the grass between the rolls. This is even with the high clearance shoes, of which my 10 footer had at least four. I always tipped the header back when passing through wood chuck neighbor hoods, but that is sometimes not enough. The rolls of course try to crush the stones along with the grass but instead the rolls are cut. I am sure that a sickle bar machine is much less likely to throw stones into the rolls than disc mocos are.
 
I've had a New Holland 477 for over 20 years (and I bought it used), never been under cover and the rolls have never even cracked. I've noticed that if a stick or bottle is in the field and I don't see it, as soon as it gets to the rollers, the rolls spit it out the front. If I don't see it in time and it hits the rolls again, it spits it out again. A neighbor has the same machine and always been under cover but I don't know the condition of their rolls. I keep my machine well greased and chains oiled and the only problem I've ever had was replacing the sickle drive belt about 10 years ago. It's been a great machine and mostly trouble free. It's ugly with some rust but sure does work good.

I've heard that Sun will do it , but my 492 sits out for the 3 years I've owned it and previous owner said she'd never been inside . Rolls in good shape.
 
In 1990 I bought a new 488 New Holland Haybine , and it has cut thousands of acres of hay , while the rubber on the rolls shows some cracks, none has peeled off. I always keep this old haybine in under cover when not in use, as I try to do with all of my equipment, and why wouldn't anyone? Nothing causes rubber to deteriorate like constant full exposure to sunlight .
 
Cracks = no problem. Missing chunks (small) usually objects, (big) drives worn out and one roller driving or being driven by the other. Rollers should never touch. Last rollers I sold before I left the NH dealer (2004)were about a grand so the rest of the machine would have to almost perfect to invest that much.
 
Hi Bill, My 1209 I keep in the shed and tarped to keep the light/sun off it. If its in the field away from home I tarp it also. I've had mine for 18 years now bought it used in great condition. The rollers have small cracks but over all no major chips or cracks.. I Dont know what the sap, juices from grasses and alf does to the rollers..
