Lawn Boy knowledge needed

That is a fantastic collector's piece.

Cordless electric could be the future of mowers since both electric motor and battery tech have improved so much in the last few decades. This mower is way ahead of its time but it's safe to say that today's batteries (Li-Ion) and engines (think Tesla) offer much more performance at a given weight.

BTW, you're really lucky that it takes generic motorcycle batteries. I think many, if not most, new cordless electric mowers have proprietary batteries (so, if you're lucky, replacements will just be expensive [only one source], not unavailable ).

I like the look of the mower -- very much like the two-cycle LBs of the mid-1970s.

Thanks for posting the photos.

I posted a short video of the mower running on you tube.

Thanks for posting that.

It seems loud -- or is it just me? Is there a gear box? I'm trying to figure out where all that noise is coming from. :confused2:

And what does the "start" position on the key switch do? I'd think on/off would be all that's needed.

I think it's very quite. It sounds like a large fan. Most of the noise is wind noise from the blade. There is no gear box , the blade is direct drive off of the electric motor. The operation of the mower page will explain the key better then me.

I haven't found any info on your model....but I wouldn't think a prototype would come with an owner's manual.
I would also think a prototype would have a very low serial number....you may also find parts that appear hand fabricated on a prototype machine.
Whether yours is a prototype or not, I couldn't tell by the info so far.
But I can say this....you don't see many of them so I would say it is surely a rare machine and a great buy at $40.

Lee , thanks for your input. I knew the moment I googled the model # and nothing came up it was special. In the future when someone googles it, my mower will come up. Pretty Cool !
I purchased my first Lawn Boy on 5-27-16 . (Model L21ZPN) I love to tinker with engine's . I now have 14 mowers and one excellent condition model1820 lawn boy snow blower from the original owner. My intent was to buy low, fix them up and sell for a quick buck. And if along the way I find a few special ones to keep , 2 or 3. Well my problem is I'm finding to many special ones. I don't have the room and my wife is going to kill me. LOL.

(Special to me, 8222 Automower, 8223 Automower , 6276 commercial , 6253 Commercial , 1820 snow blower, 1013 lawn boy Edger and now 5800 cordless )

Very nice, my 8222 is very close to that condition, the 8223 was seized when I got it . I completely disassembled it this past weekend. Piston took all the damage , cylinder lining is in great shape . When I'm finished with it I will post a few pics.

I just found a little info from an old mechanics illustrated magazine. http://www.myelec-traks.com/mi4-74.pdf

Interesting PDF, it would seem to suggest that your machine would have been produced for a limited test market, if I understood it right.
Also interesting was the Articat with the Wankel rotory engine.

Well I just had a very interesting phone conversation with Lawn Boy / Toro. They have no record of my mowers model number or Serial number in there production line up. (Mod.# 5800A & Ser. # 4950) There production model number for the 36 volt cordless mower is 5801 & 5802 ( made from 1974 to 1976) my serial number starts with a 4 . They tell me thats a 1973 model serial number but the mower wasn't produce for market till 1974. It this point I truly believe I have one of the test marketing mowers. Lawn boy sent this mower to larger dealerships to see how the public would react to a cordless electric mower as state in the article I found. I'm going to send a few pictures to Lawn Boy and see if the will respond in an email what they told me over the phone.
