Does plastic twine stretch?

[big a]

Been running 9000' sisal in my old Oliver 620 and it's always done with it. Was scared to try plastic twine, but the price difference, and poor consistency of Sisal finally persuaded me.
To my surprise, it worked perfectly, no adjustments needed, but I notice my bales all seem pretty loose about 24 hours later.
Making bricks tight enough it's hard to get fingers under the twine, about 60-65 pound bales.
Hay type, and moisture content don't seem to affect it....powder dry to "should I really bale this" wet. Alfalfa, Brome....they are solid coming out of the baler, and loose a few hours later.
Never had this with Sisal.
Any ideas?
Using Orange Bridon twine from Orschelns.

I have never noticed that type of problem. You might just need to tighten up the chute adjustment a tad bit and see if that helps. My self I will not try to do a bale over 40lbs but I'm old and have back problems. LOL

I used the 9K for a while and switched to the 7K. Less breakage, and easier on the hands....

I use the same type of twine in my new Holland 278 and running little over 110 lbs bales and not have that type of problem, I do think having the side to side tension equal is important. might want try turning the tension down a little more and see how that works but in know nothing on a Oliver baler. dad and uncles all had new Holland balers and that what I grew up with and now I am doing the same.
good luck

I use the poly twine in my Oliver 62-T baler because that was what was in it when I bought it.Makes a great tight consistent bale best bale I have ever gotten out of a square baler and I baled with JD and NH balers.The most curious thing about the baler is it has hydraulic mechanism that pumps while the bale is being pushed thru the chamber to keep tension on the bale
no screw down tightners on the baler.Bales tight stays tight.

I've never noticed any stretch to it. Try tying off both ends and see if you can stretch it in the middle. Maybe it does.

The twine does not stretch much at all. It is your hay. The hay is springy and as it sets after being baled it loses density. It has to do with the year. Some years it is worse than others. I have it happen with round bales too. So tight you can't spear them and two days later squatting and you can stick your arm in them.

Baling with a JD 328. Similar experience as far as twine seeming loose a day or so after baling. Not huge problem but wish they would stay as tight as when they come out of the baler. Also don't recall this being much of a problem in the past. Held off for years switching to plastic but finally did it last year. This year pushed out nearly 2000 bales with only two misses(except when I wasn't paying attention and let it run out of twine once).

I have a JD348 and use 9600/210 twine (with a pan kicker) and don?t see any stretch. However, our bales are spankin? tight when they come
out of the baler.

doing a little scientific testing.
Got an IH suitcase weight suspended from my cherry picker by a doubled up strand of twine.
Will measure stretch after 24 hours.

As nd seller said. Shrinkage in the hay not the twine.

Awesome idea. Love the scientific approach. Please report
findings.
I mean, granted, even if twine did stretch, it still wouldn?t loosen on a bale unless the hay shrunk. But I like that we are getting an answer here

I'm sure you'll get some stretch by hanging 100lbs off the twine, but that proves nothing. The twines in the bale have nowhere near that much tension on them.

It's hay shrinkage, plain and simple.

they sure didn't stretch much at all.
1/4-3/8" at most.
Got to be shrinking hay.

Back in the early mid 60s, when black plastic twice came out, our bailer man bought some. We helped him put up his hay. It was a hot day of course. I could at 16 lift the string up to my chin and the bale, being in a U , in the middle would be on the ground. That was a pain.
