A Land Remembered by Patrick D. Smith

I just sat around the house reading all day, mainly on the stool in the kitchen that I always sit at, closest to the big sink, made obvious by the big grooves worn into the tile underneath from it sliding, and only going outside twice.  I of course read the paper in the morning with breakfast, then finished up that last article in the National Geographic.  I skipped through a few not-worth-much magazines before getting sick of them and picking up “A Land Remembered,” which I'd been reading a little of every night and read through about 200 pages today.  The day was long, in a good way.  I didn't get much sleep last night so figured that I should take a nap and when I woke up, I was surprised at how high the sun still was and how much of the day was still available.  I'd also usually start getting tired and tell myself to go to bed around 10p, but it's past midnight now as I write this. 

The book also contributed to my weird feelings of the day.  Being taken through the rough lives of a few generations of Florida’s first settlers and seeing how different their life was from mine despite all of us living on the same land, only separated by a century in time.  The first generation of MacIveys in the book came down from Georgia into the unknown of Florida, building a place to call home out of the scrubs in north central Florida and after some bad luck there, moving again along the Kissimmee River for another generation.  I find it hard to imagine wondering into an endless woods with the thought that you would be staying there permanently, not just a little exploratory hike, but to be self sustaining.  But this book put you there.  As three generations of the family are followed, there were deaths, many of them under circumstances unknown to us and as with any good book, I cried after every family member died, as I could not imagine the family being able to continue with that person now missing, impossible.  But, they always did.

A man runs the cattle drives for 40 years, assembles the crew that sticks together through everything, from outlaws to gators and becomes best of friends with his family over that time.  He'll help anyone out and during that time period he saw whites, blacks, and Indians as all the same.  He always sits at the head of the table for dinner.  His wife has been with him through everything.  She's the cook during all of this, a fixture in the kitchen and dining table and during the drives on the prairie, and the men surely would not be able to do what they do without her.  And then they, the matriarchs, die.  And what did they do?  What did they accomplish?  Even after everything that they went through and accomplished, my feeling was still that they didn't have a complete life, they missed out on something, they just lived along a river in the middle of nowhere.  The book later also followed the third generation of the family, who lived more in my time, and caught the land boom in South Florida and became an agriculture grower and seller and very wealthy.  And yet when he died, I thought exactly the same thing, there was an emptiness.  The only way to judge life is happiness.


I get sad knowing that the way of life in the book is forever gone in the US and much of the world and I never knew it and never will.  I look at satellite images nowadays on the internet over the state of Florida and its hard to find much land at all untouched by people which makes thinking of driving a herd of cattle from the east coast to the west coast unimaginable.  I don't know if the MacIveys, the folks that lived during this time period and through that great change ever got sad about the change, but I feel sad to never know that way of life.  I know that our lives nowadays are much easier maybe, but I still can't help wondering what my life would have been like to live in those times and also feel like I'm missing out on something.

Health Insurance in the US

This is my hypothesis.

Up to the mid 1900s, doctors charged a reasonable amount of money for care; nobody needed to go into debt for a minor injury and no one certainly needed to pay two weeks salary or more for a few stitches. Then, the health insurance industry grew and doctors started thinking, "This isn't some poor family paying the bill but a billion dollar insurance company, I think that they can afford me to raise the rate a little this one time."  The insurance companies didn't put their foot down and then this process was forever repeated  and allowed the rates to beat inflation a hundred fold and now we are in the situation that we now have, where doctors charges are inflated, tied hand in hand with health insurance rates.  I am not a doctor and I don't know one personally and there are probably more factors, but this is my hypothesis of at least partly how this country's problem came to be and will be very difficult to solve.

Just found this article from the New York Times:  http://www.nytimes.com/2013/08/04/health/for-medical-tourists-simple-math.html?pagewanted=all&_r=1&

The gentleman was offered the hip replacement in the US "at cost" at usd14000, then the hospital wanted usd65k to install.  "FU, I'll go to Belguim and get the whole thing done for usd13k."

America has a Spy Agency!?

From the BBC, July 2 2013, (http://www.bbc.co.uk/news/world-latin-america-23158242)

"Mr. Snowden is wanted by the US on charges of leaking secrets he gathered while working as a contractor for the National Security Agency (NSA), America's electronic spying agency."

Man, I feel like shit seeing that written out, "America's electronic spying agency."  From the time of our birth, our politicians tell us that we live in the greatest country on earth, where we will be as free as possible and have the best chances to better ourselves, a tradition of America's leadership and politicians probably since the inception of this country.  Yet, we have a spying agency, just like Hitler's Germany and Stalin's Soviet Union and many other countries written about very unfavorably in the history books.  Incidentally, these countries also had warrantless surveillance and secret courts, and spying agencies...I don't like where this is headed...

Fortunately, three countries, Nicaragua, Venezuela, and Bolivia, have declared that they will offer asylum to Snowden.

Hydraulic Lawnmower Pump/Motor Unit Rebuild



My slightly pre-2010 Swisher 60" mower, with about 310 hours, has been experiencing poor performance from the hydraulic drive units, so I decided to do something about it.    The mower advertises, "Driven by Eaton" but I was unable to find any identifying marks on the unit's cast case, maybe for a reason, though internet research points to them in fact being made by Eaton.  My mower has a model 778014 pump and motor unit on the left hand side and a 778046 on the right, though both units appear to be identical once removed from the mower, only the removable fluid reservoir differentiates them (and which boss is tapped for the bypass valve lever).

The units had a few symptoms that there were problems.  The top speed had reduced over time.  The units would "load-up": after going on flat ground at constant speed, the mower would come to a stop with the power levers still on WFO, only to start going again after a second or two.  Lastly, the units didn't like to climb hills.  They'd completely stall and if the levers were left at WFO, they'd get some nasty power pulses, but if they were feathered a little, usually the mower would get up the hill.

I first looked up new units, just to see the cost, before I spent my time taking them apart and Sears had them for about $800...way too much for the ole mower.  The cheapest that I found was Amazon in the $500s, linked below.



$500 was still a bit rich so I pulled the two hunks of metal out of the mower, put them on the bench and started ripping them apart.  My first thoughts were that the fluid looked pretty nasty, very thick and always with a silver shine, not good, though it had been the same fluid that the machine had started life with.  I started on the wheel end, which exposed two planetary gear sets stacked on top of each other, probably making about a 10:1 reduction to the wheel, and a clutch system.

After that is the hydraulic motor, a radial piston type, bores arranged radially on a rotating "drum" with a ball acting as the piston in each bore that rides on an eccentric race thereby causing them to move in and out of the bore, which in the case of a motor, the pressurized fluid behind each ball with cause the drum to rotate.  http://en.wikipedia.org/wiki/Hydraulic_motor and an image search should be helpful.

The drum still in the case, the eccentricity can be seen at the bottom

The drum can be seen to the left still attached to the output


Next I pulled apart the pump side to find what appears to be exactly the same design as the motor, dimensionally.  Here of course, the drum is driven and the balls moving in and out of the bores is what pressurizes the fluid.  A big difference from the motor side was that the piston's race is movable, altering the eccentricity, which could reverse the suction and pressure lines, and makes for your reverse mechanism.

That's about it, I disassembled everything, used a bunch of brake cleaner, and put it all back together.  I didn't replace any hard parts, other than having to cut a new gasket for the motor side, and did not find anything in the unit that gave me alarm.  I refilled each unit with ATF and actually Mopar ATF+3 at that because I already had some on the shelf, and stuffed them back into the mower.

So how is the mower working now?  I still have not done much besides some test cruises, but I'd say damn near brand new!  Hell yeah!  The top speed is back to normal, which I had a hard time remembering, the stalling problem is gone, and I haven't tried to climb any hill yet, but doing a zero radius turn on concrete, the reversing tire can be made to squeel!  All of the problems that I'd experienced with the units just came down to the fluid.
