JD, you need to do a little research on this. I think you're a level headed fellow and you probably will.
Here's what I've found if your interested.
1) The cost of the net wrap material is about $300/roll (Vermeer and JD dealer - $289.00)
2) Cost of adding net wrap to the baler is about $4300.00 (Vermeer dealer)
3) Depending on the bale size and number of wraps of net, you will only be able to wrap about 100 bales (maximum) per roll of net
4) Doing the math, that adds a minumum of $3.00 to the cost of the bale.
5) Even the custom balers pass this additional cost ($3 to $10/bale) on to the buyer.
And here's an exerpt from one of the web sites presented above.
"Bale wrapping has some influence
on storage losses of large round bales
stored outside. A Missouri study
showed weathering losses increased as
the spacing between the twine on bales
increased from 2 to 8 inches. However,
wrapping bales with twine spaced
closely together increases costs because
more twine is used and more time is
required for wrapping.
Most studies have shown net wrap
to be
slightly better than twine in
preventing storage losses. Producers
who use net wrap have also indicated
that they can wrap a bale with only
two
to three revolutions and produce more
bales per hour than with twine. Net
wrap has the additional advantage of
stabilizing bales better than twine, thus
making bale handling and storage
easier, but it also
increases cost."
Check this out for yourself, JD. There are folks here who have vested interests in selling you something that make it sound like it's the greatest thing since sliced bread and may even promise you they can save you a bunch of money. But you will probably have to pick the equipment up in East Jesus, Maine.
The only thing that net wrap offers over twine wrap is speed and that
is a biggey as far as I'm concerned. With my old equipment it takes more than a minute to tie the bale with twine. The same could be done in a few seconds with net wrap.
Have a good one.
