They cannot deny the warranty claim due to you installing it yourself. That is againist the law. If you pushed the issure they would fold. They need to prove it was the conversion that caused the engine failure or your installation.

do not have to be certified to do you own installs by anymeans, only if you are going to sell kits to public.

Well my unit is up and running now I can start collecting some information. I had to get some help since that governor shaft had to be modified to go around the gas inlet tube. Had to have expert to do that. Bottom line a lot more to this than just strapping on some parts. It sure does seem to have more power but maybe that is partly because they adjusted the top speed. Now I am ready for the leaves. No more stalling when the right side of the
machine is high or going over bumps. And should fix the cold warm ups necessary with gas. It ain't pretty but was cheap.....I always go for cheap over beauty. Now maybe we move on to get our trucks converted. Kinda hard decision now that gas is rocketing down.

ed2hess the conversion looks good. is that from a kit if so what company or is it through parts that you pieced together? Also what was the cost?

is this your first propane mower?

No it isn't a kit I begged some parts but had about $300 for the carb, regulator, and switch. Dealer provided probably another $100 worth of fittings, and hoses and some weld work. It is the third unit we have a sentar, a turf tiger on propane.

I just put a short block in this unit it has 2000 hours and I am going
thru it and changing out bearings etc etc. Got a little extra time
these days since no mowing.

AND if you still want your unit's warranty to be effective.

Is this hard to do? No. Is it hard to do correctly? No. Folks, if you don't know gas, know your gasman.

Don't judge the merits of propane by the experience of some backyard mechanic choosing the cheapest of methods. I assume many here purchased commercial equipment. I also assume you take excellent care of your investment.

Why scrimp now? If you want to try it then for goodness sake do it RIGHT!

FWIW we have distributors re-adjust factory units before they are delivered. Why? Because we want our customers to judge their investment under the best circumstances we can provide. THAT is the reason we are so successful in this endeavor. Compare apples to apples...

I don't work out of a backyard.....and if we decide to put propane on our diesel trucks I will let a professional do it. But not on a six year old machine...And by the way I had a guy looking over my shoulder all the way that is probably one of the best propane install guys around. So what is your point?

For the bold it would need to be a fuel related failure to deny warranty (to lean or rich). If a lower end bearing goes out it would still be covered unless the mfg can prove the conversion caused it. That is the law.

For the red what distributors for factory units? Pace for Scags? Or your propane mowers on your site.

The only thing Ed is missing is an exhaust analyzer to make sure it is running properly. Plug readings, and checking exhaust temps could also make sure it is running right. He got the carb from Kohler directly so it should be pretty close from the get go.

The post wasn't referencing anybody in particular, Ed. I'm speaking from experience.

Let's face it, you can make a mower run on propane with a hose and a needle valve. Is that the best way? No, and it isn't fair to judge propane conversions using this as an example.

We recommend ALL factory units be readjusted before delivery. As far as warranty is concerned that would be between you and the dealer and, honestly, I'm not a lawyer so I can't argue the lawful point. Again, that is between you and the dealer.

An exhaust gas analyzer is fine but how would one set WOT without a Dyno? Our techs use a specialized pressure gauge to set initial and load pressures.

Really, I'm not here to argue with anybody. If I asked a question about lawnmowers or lawnmowing I wouldn't question your authority on the subject. You have too many years of practical application and experience.

I can only share my experience here. How it is used is up to the reader.

By the way, what WOULD the EGT at stoic? I'm curious...
