this is a little bit off topic of your small square baler, but it's related to what rw said.
As I posted above, I hope to put about 10,000 big square bales through mine in a year. Of that a large portion is silage hay and I have 2 hay wrappers, one inline for round bales and one individual for square bales. I run John Deere round baler also and hope to get 5-10,000 on it in a years time also. Before I bought the big square baler though I wrapped with both wrappers for several different balers and still do.
Bale shape and form is everything when wrapping. I wrap a lot of hay that other farmers or custom operators bale, we wrapped about 25,000 total between the round and square last year. Our best day, the guys and I wrapped 1000 bales in one run without sleep and baled a good share of them.
There's nothing like a Hesston bale on the square bale wrapper. The top corneres are solid and the bales flip and roll. We can wrap more in an hour when they are shaped well. The Hesston bales are nice every time. The New Hollands seam to have a 30% chance of makeing good ones, the tops just are not filled like the Hesston does. Sometimes you can't tell what baler they came out of and sometimes it's easy to tell. Running the squeezer, you can tell how dense the bales are, it depends on the type of hay, some of it just is squishy no matter what. Sometimes we can't get to the wrapping right away and depending on the type of hay, moisture and temp. the bales get pretty soft before they get wrapped. I have a lot of issues with soft bales not flipping on the wrapper table, with the Hesston bales even when they sit long enough to get soft they still flip. You can also tell in the stack after the plastic has shrunk on them, the corners are firm and the bales are square.
I think it has more to do with the shape of the stuffer chamber, and how fast the stuffer cycles. The Hesston has more taper from top to bottom of the stuffer, to allow for more hay on top of the charge. The linkage and drive for the stuffer also lifts the charge to the plunger in a progressively faster motion. starting slow and speeding up as it lifts.
The new series Hesstons when they came out, 2150 massey, 7433 agco balers at first had a fixed stuffer chamber on the side plates. My neighbor has one. I've got the old 4760. The new one will not make as nice of bale as the older ones in some conditions, but then the stuffer side plates came slotted after the first year of production, so more adjustment is allowed now which cured the problem. The new ones stroke 47 times a minute and the older ones are at 41. The new ones have a lot more capacity, and should make a better bale with more plunger inertia.
What I've seen over the years, all the jobs and places we have worked though is that the Hesston balers just plain work. When I bought one there was only two choices. A used Hesston or a new Hesston.
