Lawnmowers

That is buffalo grass which is very similar. They use kikuyu as grazing as it can handle a good drought. Subsequently it sucks in colder places. The farmers used to throw chopped kikuyu outside the cowsheds so the cows would walk it back to the paddocks for them.

Not familiar with buffalo grass but my understanding it was brought in for the coastal dune farms, for its drought resistance and summer productivity on the drought prone coastal strips It subsequently spread and was I guess spread as well. But is hard to manage and keep at a high feed value. I understand it chokes out other grasses unless it is hard grazed. Its a three season grass, basically winter dormant. in the nineties at least there was a lot of research done by the DRC, AgResarch, Dairyboard, LIC plus a group in Northland etc. They used to recommend to mulch in the autumn and oversow with Italian rye.

Lawnmowers.
Has anyone else noticed the remote-control mowers that the council is using?
Saw one being used on a steep bank next to the motorway, with the "driver" standing next to the road and the mower doing the work at the top of the hill.
I wonder if they can GPS it's movements then just hit "repeat" the next time the area needs a haircut?

You'd need some on board sensors as well, GPS is only accurate to 6 feet. Sounds pretty accurate until you think about that as a scale.

Pretty sure I don't want a hover lawn mower coming to within 4 feet of me... give or take 6 feet.

I still can't fathom why a chap of your stature is up for pushing their own mower.

I know why I mow my lawns and not the wife, It would be more painful than standing there watching her wash my bike.

What is this "feet" thing? it sounds like it might be some quaint form of measurement.

Yes... gps standards are in feet.
Because 'merika, fuck yeah!
Plus, I always read your handle as sideboob.

Sorry BD but nuts.....

GPS standards are converted from the GPS receivers 'Earths centered solution location' into latitude and longitude first....For the simple like me its how it works out where it is in the world....This is a Global mathematical measurement.

So the Inaccurate distance on one set point for the GPS unit standard is measured in Latitude and Longitude....The user of the unit decides if he sees this measurement in feet or meters by selecting an option for the unit to display(One reason why you need to select a country when your first boot up you shiny new GPS......In the USA it will read 10 miles to your destination in NZ 16kms

So if yah saying feet here in NZ then your just old a yank or both

I stand corrected. Last time I read the standards they were in feet and yards.
The current published standards are in fact in meters.
Oddly the required accuracy to say your device meets specification is no longer as high.
I wonder if this means Mil spec is now a seperate spec?

A very good question.....I am not sure but now want to find out.

Latitude and longitude is pretty spot on measurement wise.I think its the satellite moving/Time lag thing that's leads to inaccurate GPS locations.
There must be a different spec standard for Military use for accuracy/security reasons....A miss of 6ft...1.8mtrs could be the difference in finding your buried supply dump in the dark or Abduls house or not.Just like our lawnmower here.

The military train in lensatic compass map readings so Mills not degrees.....Thousands not hundreds as this is more accurate...180degrees....1600mills.
Get your compass maths wrong by 2degrees over a 30km walk and miss your target by kms walking right past it.

Correct Comrade Akzle.

At high school a hike leader got his maths wrong and lead us up the wrong mountain. He started believing me about the same time the doc track stopped. From there we could see the hut we were supposed to be staying in.
Probably only a km as the crow flies. Somewhere between four and six hours walk was the difference between true north and his calculation for deviation from magnetic north at our latitude.

I still question his leadership that in spite of a track forking and not marrying up with his calculations he didn't check his maths.

well, to be fair, the poles are shifting...

[Big Dog]

And 2 degrees is a long way off on an 8 hour walk.

You can get A sub 1 meter system self drive for tractor is called something star. (Can't remember what)

I seen a road test where the tester drove the tractor to the pub and set the swath width, to the width of the road and the tractor then drove him home again, hands free.
After the council mower had been used the first time (by remote control) if the system was decent, it should be able to mow it without remote control next time.
It could also be ran from a system similar to a geofence.
