Burns cleaner less fuel related problems, almost Zero carbon... But has about 10 to 20 percent Less energy, and is far less handy to refuel, along with the availability of close at hand sources of fuel... I use to do small & medium farm tractors using LP ... no one ever did large HP tractors with LP.
You will burn more fuel for the same job, but it fuel cost's less per gallon.
A small leak can be much More damaging in an enclosed building, than a small gasoline leak.
I suppose the cleaner burning is it's Largest positive, and that may be enough to consider getting New equipment rigged for it. I don't think I would convert existing although I have converted a few gasoline generators to nat gas or propane... :smile:KennyV
You should have made your user name HANK HILL
It's funny you should bring this up, yesterday I was thinking about a propane conversion while I was mulching the leaves. I don't know how cost effective it would be for a home owner, but around here propane is a full $1/gallon cheaper than gasoline. The thing I really like about propane is its ease of storage. We have several local sources of propane, so refueling isn't a problem either. I don't know how much the conversion kits are, but I'm sure they are priced high enough to make me wonder if they are worth it.
Funny you say that! If you attended the Kawasaki schools where I presented, you'll recognize this: YouTube
I don't know what your mower is but, typically for a residential push mower, around $300-400. It should be OHV though.
If you know what your annual gallons are you can go here to see if it's worth it:
Clean Fuel LPG Propane Conversions, Eco-friendly
The mowers are in my sig. Neat calculator. According to it, a conversion on both mowers would take about two years to break even.
Thanks! I made that!
I'm curious what your five and ten years savings are?
Well, I'd have to go back and refigure, but I'm thinking the 10 year savings were in the $1,500 range. Since I have two motors, it would take two conversions, or roughly $800. My savings for the first two years would pay for it.
I used local propane and gasoline pricing. Around here, gasoline has recently been creeping up towards $3.20, and the last propane I purchased was $2.19, which was about a month ago.
Hi Kenny,
Yup, propane has 10% fewer BTUs than gasoline but has a minimum 107 octane so you get a bigger "push" from each stroke. Go here for an independent study:
http://www.utmb.edu/tstem/tstemutil...Ansis MannieRondina_Propane_Vs_Gasoline_2.pdf
Here in Boise propane holds a 60% advantage over gasoline in price. Availability is better for delivered propane than for gasoline.
I'm surprised to hear you say that propane is less safe than gasoline. In an early 80's study it was deemed 10 times safer than gasoline in that it dissipates rather than pools. As far as using propane in enclosed spaces I need only to point toward propane powered forklifts in use.
There are tons of "old-wives tales" about propane horrors. I've been doing it for over 35 years and I have yet to experience them.
We fear what we don't understand. If you don't know gas - know your gasman...
Cheers!
Higher octane does not give an engine a better performance. It justs burns better and reduces engine ping, but that aint common in mowers.
As for the "old-wives tales" about propane horrors...they sill happen.
I guess I'll have to take your word for it as I am unaware of any propane related accidents for mowers. .
My word for accidents while using propane for mowers???
I do not think it has been used long enough on mowers specifically to have any meaningful statistics...
Gasoline has been used for a Long time and most folks are very use to handling it... but that in itself is not saying gasoline is accident free. :smile:KennyV
And propane has been used as a motorfuel for almost as long. With an excellent track record. As far as octane not contributing to performance, well, to say "it doesn't" is a fairytale. Ask anybody who races. Propane isn't for everybody. There will always be some who don't understand it. Look at the Amish...

If you was to run propane in a race car your just going to ride around in last place.
Alright Terry, trying to keep this as related to mowers...
Like I said: I have ran AG tractors on propane, I've used it, & still do use it but Not for mowing or in any engine anymore...
octane is required in Most fuels, but it is not a condition of higher octane (107) is going to make more HP in a small engine... There are mowers that barely have enough HP running on gasoline, switch them to propane and they will have Even Less.
So as to "ask anybody who races", (I've done that)... as far as I know no one has won many races running propane...
As far as the Amish not using propane, it is Not because they don't understand it!
You are just all over the place trying to defend propane... It dose Not need this type of defense, It's been used for a Long time for quite a few things... If it successfully gets into "common use" as a fuel for lawn mowing is yet to be seen...
it 'could' be used in almost any application, But I don't think you will find it extensively used in Aircraft Or Boats either.
My original thought & experiance was that propane is Not as handy a fuel when compared to the Most common used motor fuels. :smile:KennyV
Ooops! Meet Susan Roush McClenaghan at GIE+EXPO, October 24-26, 2012 | AmeriGas Propane Blog Don't you HATE it when that happens? What else can we discuss that you know absolutely nothing about?
I'm all over the place? I just quote facts, not opinion. If you wish to debate the facts, answer with facts. It's that simple.
There certainly ARE mowers that are put into service for something they are not made for. Are these a good candidate? Hard to say.
Honestly, I really REALLY would like to see your reference as to a drop in horsepower. All I have to go on is seven years hauling a dyno around setting up Schwann's trucks - noting the before and after.
Actually there IS an aircraft application in the works. It's been used successfully in boats for years - four stroke only.
For heaven's sake, if you like using gasoline or diesel, keep using them! Just quit with the fairytales about propane. Sometimes it's best to be silent and thought a fool, than to speak and remove all doubt.
Octane plays a big part in how a engine will Performs.
It really does not give any more hp.
One big thing for a race engine is the high octane gives you a faster throttle response getting you to max rpms faster. And will hold the rpms Gives the illusion of more hp. And with running high compression 14:1 if you run a low octane gas your going to burn a hole in a piston.
Now in you factory car or truck you are not going to notice any difference in every day driving but will get better gas mileage maybe 2 or 3 miles to the gallon.
If you was to run propane in a race car your just going to ride around in last place.
Let's tell the whole story first off she is using a propane mix that we can not get at the local hardware store.
Second it cost her daddy around 1.5 mil for her to win that year. Her team mate who also runs the same set up as her did get second she beat him in the final pass.
We all know that in her class that at one time was stock street legal the one with the money wins. I read that the team saves about 70% using propane over race fuel but still cost more per pass because of the mods to the engine.
She one the points but never had the fast time. The car or the propane did not win the driver won by her skills as her car was never the fastest.
I called my machinist and talked to him. His opinion is my 30 thousand Dollar engine would turn into a 60 thousand dollar engine with the mods to the engine and car. I would lose pull out of the corners and blow more engine because would have to run a wet sump and not a dry sump.
Susan has to do a short build after every run where as the ones using racing gas can get 4 or 5 runs as her class can not run alcohol.
If the info I have found is wrong or not in line with what you think or know then fine
But there is no need for you to be a dick
I do not even use a propane grill
A propane mix? It's HD5 the same as you use in a barbeque. Actually, yes, you are wrong as is your machinist. Actually most of your statement in incorrect. I'd really like to see the references you site. Really! We've just been her sponsor for the last five years...
i got into this BS with him already u guys wont win he will post more crap why its better ,who uses it for what and so on ....I told him here in Canada it was used in the 80s and 90s on cop cars/cabs/sears Canada had over 2000 vans that ran it plus we had trucks that had it also ...They all got rid of it do to cost and availability and maintenance on a ageing fleet ....most went gas and the bigger trucks went Diesel
Ok your right every one else is wrong.
Again I do not use a propane grill
I thought brigs and Stratton recommends to swap out valves when converting to propane because propane doesn't have the lubricating properties that gasoline does,and are these small engine conversion kits a spud in type or just an aircleaner modification,and as we speak CBS is talking about hydrogen powered cars,so I cant wait for the hydrogen powered pro attachment series trimmer from stihl.
OMG did you really just call me skooter? Like you said all the info is on Google but when we read the study's that go against what you are saying you go to throwing out insults. Do you know about propane? Yes. But why is it that what you say is facts but what everyone else has to say is bullshit? For most of the people on here propane mowers are just not going to save us money or timeJust who would be "every one else?" Sorry, Bud! You're just wrong... Talk's cheap, Skooter. Let's see your documentation.

If your aim is to debate your are doing well enough. If your aim is to promote use of propane you stopped making headway back on page two.
I don't understand.
THAT is Exactly your problem!
Your are one of the most self centered that has came along to these forums in a long time.
No one here has any desire to "prove 'it' to you" or 'change' your opinion, Yet you are a broken record with your one dimensional blather.
I certainly hope you are Not in sales of any kind, as any company having You as a representative would have to constantly overcome the Negative taste You leave behind. Your approach here has been as if this is Your pulpit and You are going to Preach At us until we are converted. Anything that doesn't fit into your narrow view has no validity.
You have done No good for propane that I can see, Fortunately you have Not mentioned the company you work for, so you have not drug them down with you.
Your trite & dated innuendos have Not been well received here. Perhaps your form of 'dialogue' is best used where the audience Has No choice and can Not voice any opposing view.

Very well said as always.
You have the skill of putting into words what others are thinking.
Actually, it was suggested to have hardened valve seats back in the late 70s. Not since the advent of unleaded fuel. Gasoline has no lubricating properties. As a solvent, it's just the opposite.
There are many different types of propane conversions. "Spud-ins" haven't been around for some time and I would avoid them. I think their use is part of the problem we are experiencing here.

from what i gather nether do the rest of us that oppose it Hank
This is not facts. Can you post a link to where you found this?
Only I know the real facts.
Thought I would save him time and post this for him.
I'm not going anywhere...
Reference to cylinder head damage tells me this info's at least 15 years old though.
BTW, when you "cut and paste" paste into Word first then copy and paste from there. Just trying to help...
it was from 2008 and up smarty paints And yes u are correct i did copy and paste boy u are smart lol did u go to school for that to ....But as i said I will post links when i get home i found about 30 plus saying its crap
Not many computers at the University of Washington when I attended. Mike, really, you're making it personal with the name calling. Don't let it get to you! I'm not too old to learn something if it's presented correctly. The plain truth is I am ABSOLUTELY interested in ANY study related to propane shortcomings! Many times it's the backyard mechanic who ran garden hose from his grill bottle with a needle-valve throttle swearing that propane is useless. Many studies cite "Propane has 17% fewer BTUs per gallon than gasoline." This is true, but why use "gallon" as the reference? Why not use "pound" or "dollar" or cubic foot which will give propane the advantage of up to 30%? It's all in how you present the "facts". The information I post is NOT mine. I can post as to personal experience but the facts I cite are mostly from customers and Governing agencies. I assume there are those "riding herd" over these folks to present correct findings. Wouldn't you think? I ask for "facts" because I can debate facts. Without facts debate turns to argument. I don't mean to sound arrogant. I'm sorry if I come off that way. I'm used to being the expert - that's what I do. Nothing so far in this debate is "new" to me. I've heard it many times before. I suppose a lot of it is our industry's fault with the technology we had in the late 70s and early 80s. Those conversions had problems but we learned from them. Technology has come a long way since then. Today's closed-loop EFI propane systems get very close to or exceed the performance of gasoline. Clean Fuel USA is making medium duty trucks with higher compression engines that no gasoline engine can touch. It boils down to the physics of the fuel. Ethanol not withstanding. Ethanol is just wrong on so many levels. I have learned many things about mowing perusing this forum. Personally I wouldn't even THINK of questioning the experts here. Believe it or don't I've even learned a thing or two about generators from this "Briggs" guy. I can put that knowledge to use since I distribute Champion Equipment. I'm not too thick to realize that the Good Lord gave me one mouth but two ears...

This link seems to support propane?
Alternative Fuels • View topic - LIke to convert to propane, but what do you think of this ?
Again, there's pros and cons. I really don't understand the continued remarks about exhaust valve recession. What causes it:
"Lead additive in petrol prevented wear (recession) of the exhaust valve seat under the combined effects of heat (due to combustion) and valve closure (hammering on the seat). Lead acted by inhibiting impact welding of the valve on to the valve seat. Such welding, even on a microscopic scale, eventually leads to a significant loss of soft metal from the valve seat in cast iron heads, and allows the valve to sink further and further into the head.
The withdrawal of lead from fuel removes the protection your engine has enjoyed for all its life."
I don't know what else to say. Isn't Canada using unleaded fuel? The only thing I drive there is my Mooney.
Gas 2 | What is the future of fuel? What's new? What's next? Since 2007, Gas 2 has covered a rapidly changing world coming to terms with its oil addiction.
This would be pointed toward reasons NOT to convert. Ok. I agree with some of it but the material is somewhat dated.
I don't know how old you are but I'm 56 and remember as a young man the engines of that age. They were powerful and then some. Then came the age of unleaded fuel. Engines were detuned, compressions lowered and low-lift cams and smaller valves were put into service. Engines continued to be detuned to match the quality of the gasoline mix available. Is it any wonder that propane doesn't perform as well as gasoline?
I wore-out the engine in my 72 Chevy PU at around 300,000. I put in a new longblock at 11:1 with hardened seats and an RV com gained over 100 horses.
I found this statement noteworthy though:
"Of course, BTUs are only one small part of the overall equation. It doesn稚 take into account the thermal efficiency of a fuel, it痴 detonation-resistance, etc. all of which, if optimized, can tip the scales towards an alt-fuel痴 favor but we*e not talking about building an engine that痴 optimized for a given fuel. We*e talking about converting an existing engine that痴 been optimized for gasoline. See disadvantages no. 1 and 2, then start adding up the cost of the turbos, intercoolers, injectors, etc. that you値l need to buy and tune for to optimize the engine you*e trying to convert."

Again, this seems to support propane doesn't it? I found this statement amusing:
" Inhaling propane can be extremely dangerous and potentially fatal." Propane is non-toxic. The one and ONLY thing it does is displace air when you breath it. I suppose inhaling it can be dangerous if you ignite it.
Thanks for bringing up these references! I'm being very serious! NOW we are having a discussion!
if it displaces air then what are going to breath ,,As for the rest yes u have to weed out some of the stuff ...But there is tons more out there ...No we don't use lead fuels anymore ....Pick it apart all u want ..I don't care lol...I could careless if they made a propane unit ..But I do know that after one is made and they start using them it will be nothing but trouble and they will find out its all bullcrap like it was when they said it would be cheaper to heat your house with it blah blah blah ..Been there to went to propane cost 2 times as much as my oil did ...Went back to oil and wood combo ....Oh and I am 40 by the way ....Propane makes a mean cheese bugger I can say that
anyways its been fun ..On to the next this is boring me now ...Enjoy talking to yourself wish u well
Ok, take care and have a great Christmas or Boxing Day if that's your choice! I mean that sincerely. My intent wasn't to offend you Mike. I AM happy that you did some research though. Perhaps others can benefit by this thread by doing their own research. The anonymity of the internet makes us say things we typically wouldn't say face to face. I would like to apologize to Einstein and skooter, you know who you are. I watch too much Ron White...
Ok so explain to me how I will save money because I just don't understand.
My mower has a briggs 24hp twin I put over a 1000 hours a year on it and only keep it for 2 years. I use 16 gallons of gas per day.
So I pay to convert it to propane. How much ?
Then I have to find propane and carry a heavy spare tank with me.
Where do I get the tanks filled?
I know of no place within a hour that fills tanks.
Then have to mount the tank on the mower in a place where the extra weight will not hurt how the mower handles on hills.
Not trying to give you a hard time. I really don't see how it would save me money.
Ok so explain to me how I will save money because I just don't understand.
So I pay to convert it to propane. How much ?
.
Without an exact engine# for Briggs it's hard to say. A 24/26HP Kawasaki with a single tank mount would be around $600. Your propane supplier usually supplies the cylinders.
Commercial mower fuel here last summer was $1.61/gal with gasoline at $3.85.
I'll probably just stick to gas until either the government enforces it, or I see all the comercial opperators using them. Its hard for me to switch when gasoline is proven, it's reliable, and it's easy to get, and it works fine.
