Electric Riding Mowers?
 
What is the latest state-of-the-art for electric riding mowers (new and conversions)? All of the threads I have found are old, and the technology is advancing rapidly. In the foreseeable future, I will have 1.5 acres to keep mowed, and I really don't want to burn fossil fuels to do it!

Did you check ecorenovator?

You just need a bigger, better battery to mow a larger area like that...that's where Leaf battery modules would come in handy. Converting a mower would be relatively easy.

I've only seen one factory built electric ride-on mower so far. It was stupidly expensive, and not remotely impressive.

To mow 1.5 acres in a single charge you'll need a lithium pack for sure. As it is I have a 1 acre lot and I have to mow in multiple charges, and to be kind/easy on the batteries which are lead acid. I love the mower but it certainly hasn't been the most economical machine.

Perhaps you could reconsider the idea of mowing the whole thing? Look into prairie/grassland ornamental plantings.

This one's a hybrid, but needn't be:

Has any one tried to quantity how many KwH per acre it takes to mow?
To see how doable and affordable such a rig would be.

Put some goats out there. Then you get free milk too.

From someone like us who has already done some math:
Lawn Mowers I - John Saves Energy

Quote:

My ½ acre lot with ~¼ acre of lawn requires ~0.7KWH of energy from the battery and 1KWH of electricity to recharge the battery. That’s about 10 cents per week to mow my lawn. Since solar panels provide all my electricity, my lawn mower is effectively solar powered.
So...~4kwh per acre. 6 to do his 1.5 acres. Just a rough estimate...YMMV.

That's a fair bit of juice. 60-cents per mow at our electricity rates here...but still a lot less than you'd pay in gas. You'd need roughly an 8kwh battery (as you can't drain 100% of a charge)...enough for an around-town EV!

(If i was doing it, I'd be building a multi-purpose battery)

Thinking "hybrid"...If you were generating electricity, and mowing it in an hour, you'd need an engine putting out 10hp continuously, which would chew through approximately 2.6 litres (2/3rds of a gallon) of gas an hour...at our gas rates, that's about $3.25. You guys at $2.50 or so a gallon would still be paying $1.70.

OP: How much fuel are you using to mow it at the moment?

The only problem with goats is they pull the grass entirely out, including the root. Male goats also tend to stink a lot, unless they're castrated.

My wife tells me that the back half of the property will be mostly garden. Itat will leave an area that is still too big foe my trusty Neuton push mower though.

I mowed and weed wacked around my house in Virginia which had about 1 acre of grass with 120v push mower and weed eater from 2006 to 2011.
After the first few months I devised a good cord layout scheme it it wasn't much trouble after that.

Somewhat like mine, which is mostly garden verging into semi-native* plant areas in the distance. I can do the lawn areas with my B&D electric. Takes more than one charge, but they're smaller "islands" rather than one big lawn, so I don't have to mow the whole thing in one go - and frankly, I don't want to anyway :-)

*Semi-native meaning about anything that takes a minimum of care, and will survive with at most one watering per month. Lots of penstemons, California poppies, flax. Species tulips & bearded iris do surprisingly well.

Vegetable gardens love wildflower gardens nearby.

there are all sorts of things you can plant that look good and replace grass that exists only to be mowed.

I have also been thinking about doing an e Electric Riding Mower conversion.

Has anyone seen what this guy did?
He also sells plans for his build. I have no affiliation with him just wondering what people think. He claims that it will mow up to 2 acres on a charge.

The GE Electrack tractors from the 1970's work well when updated with an Altrax controller and solid state battery charger, I think they are good for about 3 acres.
They can also tow a decent amount.

I did a Google search on the GE Elec-Trak and now I'm hooked!

Elon Musk, here is your next product line, Tesla electric Garden Tractors!

Wow how did I miss the replies to this thread. I have wanted a GE Elec-Trak E16 for a log time but they are hard to find in my area. Also either people want a lot for them or they are very rusty/worn out.
