Stihl 510 vs Husqvarna ProFlex Mower

with 2 comments

My “job” has me defining-providing-managing energy solutions for telecom at difficult locations, and so I am exposed to a vast array of technologies for energy storage and power production. In this role, I constantly validate the effectiveness and performance of power and storage solutions.

So with this eye, I decided to look at what are the benefits and are their real gains with the new battery electric mowers versus my traditional mower?

In short, the answer is yes – get a Stihl!

lawnmower_DSC3057

The attached picture reflect 1/3 of the property I maintain (I am not including the woods behind the raspberry and blueberry bushes well beyond what we can see (on the other side of the house)).

Husqvarna ProFlex 18 with a 42″ Deck and Articulate Steering

The Husqvarna is a well made (fair design) 1999 riding land-mower with 18hp Briggs Stratton Gasoline Engine with Hydrostatic Transmission that supports a garden trailer.

  • With its 42 decks, I can cut the lawn in under 90 minutes.
  • I can consume 3+$ in fuel on a cut.
  • Generate 0.009 Metric tons of GHG (Green House Gas) with each cut.
  • My annual maintenance – from oil changes to overhaul – averages ~ 200$ a year.
  • My fitbit erroneous says I walk 8000+ steps once I am done bouncing around.

Stihl RMA 510 with 1 80 AHr Battery purchased this summer

Is a well made and well design lawnmower. As I see traditional mowers – including the premium brands, such as Honda – making their units cheaper – I appreciate Stihl focus on quality and ease of use.

I also considered Stihl’ service network, so I do expect in 10 years, when I need a new battery, it will be there.

  • Depending upon length and wetness of the grass, I need 2-3 charges to cut the property, which requires about ~200 minutes.
    • It is a slow recharge, so the activity- unless I buy another battery – takes two  sessions (afternoons) that last 50-70 minutes each,
    • Husqvarna is 2.5x faster
  • My cost to cut the property is about 0.15$, based on a burden cost of 0.17$ kwh, as measured by an un-calibrated energy meter.
    • I was surprise how low it was, so I have since calculated (again using my  experience in doing similar work (as my profession)) and confirmed this.
    • Husqvarna is 20x more expensive to operate
  • I generate less than 0.0002 Metric tons with week cut.
    • Husqvarna generates 40x more GHG
  • I expect my annual maintenance will be less than 60$ a year, allocating 40$ a year for battery replacement and an occasional blade replacement.
    • I would expect the battery support 2000 cycles (assuming I do not let it freeze in winter). As I am cycling the battery twice a week with a cutting season less than 8 months, I am generating 80 cycles a year, thus my battery life will be more function of aging chemistry (versus cyclic life). It is reasonable to assume 7+ years (10 is possible), and with the battery after taxes close to 280$, I am allocating 40% a year for battery replacement.
    • Husqvarna maintenance cost 3x than the Stihl.
  • And I am generating about 13000 real steps to cut the lawn.
    • I was once nudged by a old local farmer on an adjacent property to use a push hand mower to cut the lawn for ones health.
  • And the quality of the cut is very good (I would argue, better).

Summary

Unless you need a tractor mower, your first choice should  be a good battery operated lawnmower.

I can foresee the day, when gas is frowned upon – rightly so – as quality electric (battery)solutions are available.

Disclaimer

I am not on any podium saying you must, should or need to go to an battery operated lawnmower.

I have no sponsors and nothing has been provided for free. I am just a “power-energy” engineer, who can confirm this is a wise decision.

Zeiss Milvus and more

leave a comment »

There are several different formats of art I appreciate – watercolours, print and very much photography. Of the three, it is photography that is a continuous draw.

So yes, I have made the migration to digital, though trying to hang onto to Black+White on film, but this issue is time.

After many years using the Nikon D600 there are a couple of features on the higher end cameras that I would like – wifi interconnectivity and more focus points – that I had no anticipated when I bought the Nikon.

In this journey, I have settle on the Zeiss (prime) Lens as I want the precise manual focus control, but really like the transition from sharp to soft. And of recent, I completed my collection with the purchase of the Milvus.

So a sampling of my images of recent and some old, illustrating what I like to do with my “seeing”. In all cases, I have cropped and reduce the image to 700pixels, but otherwise no other photo-editing.

For those images not in my backyard, I have identify the location.

The Milvus 50mm Macro

From Yesterday, a tree frog on the sheets last night. Here, I keep the depth of field short to put emphasis on the eyes.

and earlier, showing a sharp image across the sensor, and ability to hold a strong edge.

and continuing with black and white and using what the camera and lens can do

BW DWW_0831

and from my initial experiments showing the blend from sharp to soft. The fancy term is describe this is bokeh.  You need to pick which you prefer.  Judy uses the third image as her background on here computer.

and my background?

Zeiss Distagon 25mm

Then there is my 25mm Zeiss lens. In the world of  high end lens, this lens does not get a lot of love, but I picked for its strength of great wide close-in images, which I did in the following pictures.

And returning home, the Zeiss Distagon is not a slouch for landscape

But when I look for grand landscapes, I look for wider, so my new acquisition

Between storms 3 days ago, which I have to transform to Black & White.

Marketing and Reliability

with 2 comments

Wow, which would you believe?

  • Traditional Philips Tungsten Longlife Bulb that will provide only 1 1/2 years life
  • The Philips LED light for 10 years.

philips reliability

Sadly, I still have bulbs – tungsten – in use after 13 years in our house, but I have yet to see a LED or Compact Fluorescent last 3 years. Sadly, the current generation seem to fail sooner too.

There are many Youtube clips identifying why LED bulbs fail early (as they race to be cheap). Myself, I rather buy a more expensive bulb that will last me of 10 years of use.

NO to iTunes

leave a comment »

So on my last venture, I decided to confirm how many of my purchased songs cannot be played when I am not on the network – 60+%.

Nearly 2/3 of my purchases are not available on my travels – whether in a plane or remote locations through-out the world.

itunes pain

wow!

what a waste, and so the lesson with these arbitrary digital leasing rights from Apple and the publishers ….

.. NO to Apple iTunes

and buy the Media and own the song for you life – whether you are at home, in a place or in the desert is the Middle East.

Yesterday, I bought a CD from Stockholm’s First Aid Kit.

first aid kit

so, I continue to be a consumer of music, but I want to listen to the music on my terms.

Home Hardware ~ shrinkflation

with 2 comments

thread_DSC1926

In the 80s, when Judy and I lived in the Annex (Toronto), we used the Home Hardware store on Bloor. It was small and amazing what they had in there. The tools we bought then are still in use today, as quality tools.

But with time, as Home Hardware chased the Walmart model of “rollback the price”, we have seen and experience rollback the quality. Though this is a trend that we all have seen appliances, et cetera, it is a trend I try not to get sucked into.  So, we learnt to not buy tape, hand-tools and now screws at Home Hardware, and hence, we infrequently go there.

I keep a stock of Robertson #8 and #10 Wood Screws at hand in bins (from 3/4″ to 3″), and buy in bulk (100+). Here are two screws bought at Home Hardware recently (on the left) and a decade ago (on the right).

thread closeup _DSC1928

The two threads on the recent screws – what is important to hold your work together – are poorly formed, misshapen and the second thread is nearly non-existent. Seriously, is this any better than a spiral nail?

Oh yes, it is smaller and with less metal. If you put it on a fine scale, you will find the new “wood” screw is 12% lighter (less – shrinkflation)!

So, a cautionary tale – beware of companies passing on poor materials, as they chase Walmart – versus differentiating themselves as a supplier of good materials.

Albums please

leave a comment »

Okay, I earlier announced my migration from iTunes to albums given the complexity-inconsistency of the application of digital-rights as time moves on. In the past week, I have found another reason – I like listening to albums, as I walk-run.

So I finally getting back to a balance life and getting to spend time doing some long-distance walk with limited running.  My cardio is hanging in, but my leg muscles need some work. So after my 7th consecutive day, I am finding I prefer to take my 60+ minutes pushing my body listening to an album that is well-strung together, such as

  • Chris de Burgh – Spanish Train or Crusader
  • Alan Parson Project – Eve, I Robot

I still think (suspect) great albums are being made, but as the focus has shifted to tunes, I am not sure the same focus is on a theme for many album, but a collection of pop songs.

So I need to rethink-return to Album listening and build a new library, that appreciates well crafted albums.

fitbit

Todays’ work-out in Johannesburg.

Oh yes, I really enjoy listening to many classical pieces, especially some of the more modern interpretative work – think Quiet City by Aaron Copland – but it is not music for me to walk-run hard to.

Same for Oscar Peterson, enjoying listening to it, but not when pushing myself.
