Lots more out today, it really is beginning to be easier in the mornings with 60 or so feeding themselves and not needing bedding, just the bigger half to get out now.

No, that one didn't have quads, just a responsible mum looking after the babies whilst the others (and several calves) went off at escape velocity.

They do look happy in the sun though, this lot are all just over a week old.

Very interesting. Why the big gaps between rows, does it need to be replanted every year. How much does a bale weigh. What's the weight of the harvester?.

These are dryland ( ie - not irrigated ) crops. Basically grown on stored sub soil moisture ( which is why we are so big on zero till & stubble retention ), rather than relying on in crop rainfall. The "skip row" areas are to provide a reserve of soil moisture for later in the season, as the plant roots grow across into it. It is quite possible for us to grow a crop on no or very little in crop rainfall, given our soil types ( heavy clay ) & appropriate management. But - we won't plant a crop if we don't have a full profile of moisture to start with ( generally, at least a metre of depth ).
It is all about trying to maintain consistency from year to year, good and bad - rather than chasing the biggest yield & just always hoping for a "good" year . . .

Cotton is planted annually. Planted Spring, picked / stripped in autumn. In a dryland situation it is usually part of a rotation with cool & warm season cereals & legumes as well . . .

Err, a "bale" in cotton speak is 227 kg of pure cotton fibre after it has been ginned, removing all the seed & trash. That is the unit of measurement used for yield, marketing etc. The round yellow bales - "modules", or "rounds" vary a bit depending on crop, conditions etc, but would average around 2 - 2.5 tonne. Each module averages about 3 - 3.8, 227kg "bales", depending on ginning results & turnout percentages. The seed is also a valuable commodity

The stripper itself weighs about 25 tonne I think & the 12m front weighs about 5 or 6

The front literally strips the bushes, using rotating nylon brushes & rubber bats. This takes everything, including a lot of trash, leaf, bracts etc. This is the main difference to a cotton picker.
Looking at the above pic, the cotton is then blown up the feeder house, through that first skinny tube behind the cab, into the gin or "cleaner". This has a series of revolving saw teeth & nylon brushes that remove a lot of this trash & drop it on the ground under the machine. From the gin, the cotton goes into the accumulator, before going into the bale chamber. The accumulator holds cotton, allowing the machine to continue harvesting while wrapping a round module & while the baler is open ejecting a completed module. Effectively, the only time you have to stop stripping is when you have to change a roll of plastic wrap. The round module cotton pickers work on the same principle, minus the gin & with completely different front & heads. They have a much larger accumulator as they are generally used in higher yielding irrigated crops
The bit right at the back is the module handler, which folds down & carries the module after it has been ejected, until you choose to drop it somewhere appropriate, as shown it that video I posted earlier
The round modules are 2.4 m in diameter
These ARE a big machine & run a 500 hp engine
In a light crop I'm currently using about 54 l / hr fuel, but am doing about 10 ha / hr, so only using around 5 l / hectare, which is a lot better than a header ( sorry - combine :) )
These & I think the CP690 - the equivalent cotton picker - are about the only JD machines in Oz currently that run adblue & DPF
f**k me, they generate some heat when that big BBQ on the side does a burn . . .
