Propane powered trimmers??

[Slackdaddy]

A few years back propane powered trimmers and yard equipment was everywhere,, now nothing?

What happened to them? was there an issue besides the small green propane canisters could not be re-filled??

Looking for a small 4 stroke propane trimmer engine,,, for a project with my son.

Most small gasoline engines are easily converted to propane. That would be just one more project on top of a project.

Now, I am pretty old, and have seen a lot of things, but I have never seen, nor heard of a propane powered string trimmer. Or any other lawn and garden power tool...It is as if you had said , "back when I was a kid the sun came up in the west". Or something similar.

Can't say that no more:

Eco Friendly Zero evaporative emissions.
Easy Start No choke, No priming, No winterizing.
Economical More cost-effective to use & maintain. 2 hours run time on one canister.
Powerful Four Stroke engine. 110 octane.

Technical Specifications
Egine: 25cc 4-stroke
Fuel Type: Propane

All I see is new though, not something you'd want to scavenge the engine off of for a hobby.

So why would anyone want to spend 3 or 4 times as much for propane fuel and lug around a heavy 4 stroke engine with a steel cylinder hung under it and create all of that landfill waste? No wonder I had never heard of them. Who would buy one? I sure wouldn't. Yes, I know the little cylinders could be refilled, but most people do no know how, and it is difficult to completely refill them, and it takes time, and you really need a freezer to put the cylinder into etc. But at least I can say I have seen one now. Or at least an image on one. With the proliferation of battery powered yard tools, I bet those propane ones sell like hotcakes.

Right. What would be the point? Not like you are using it indoors. Less bang for the buck.

Curious now that I think about it. It would require oil injection for a 2 stroke or be four stroke.

Apparently a 4 stroke, which means more weight.. And lets see... would need to remove cylinder after use and store in a non enclosed space because if the fuel hose ruptured (under pressure) and emptied the cylinder it would fill your garage with a nice fuel/gas mixture, and one light switch spark, and it blows your garage out. .. could happen.

14 to 15 lbs WITHOUT the fuel canister.. depending on which model.

I have actually worked on that exact trimmer, and may even have one in the bone yard that somebody ran without oil.

You are not alone James, I had never heard of such a thing either. I find it odd that while being a "tool connoisseur", I never ran across one but nevertheless.........

More so than the Lp trimmer

They make refillable containers. Three years ago I paid just shy of $10 for one so the price is crazy high right now. I use them camping in my RV as I prefer to cook outside. At one time I had a propane battery shower when I had just a pop-up. Yep, never knew they made propane trimmers.

I really loved driving two ex police cars, one factory propane (Dodge Diplomat) and the other a converted Malibu.

Loved the smell, and just the thought. Engine oil always looked like the day it went in.

Never heard of one either. When i use my weed burner on my drive, i have 20 pound cylinder on a hand truck. Even with that, still not a lot of fun.

 

[Slackdaddy]

So, to answer a few questions.

I am building a propane powered "outboard" for his kayak.
I can get a min outboard "lower end" that accepts a standard weed wacker motor, cost 40-50 bucks.
I don't like gas outboards for a million and one reasons.

If I can find a used propane weed wacker, pull the engine and bolt it on the outboard lower, then replace small cylinder connection with a hose,, I have a few 4# refillables.

So I would have a 1hp propane outboard for the kayak for ~100 bucks

Ok, so that should be a build thread, all by itself. I'll subscribe.

soon as I find a propane string trimmer, I'll get a thread started

Have you looked into getting a propane carb for a replacement for the gas carb?

Here is one from ebay:
