Has anybody converted a Hustler Super Z over to propane, or does anybody currently run a LPG mower. I am thinking about converting because of the efficiency and cleaner running fuel, but I don't know how well it actually works in the green industry.

I've seen one of the manufacturers already offer an LP powered mower, can't remember who. It had a tank like they use on fork lifts.
I've heard one day ALL mowers will be LP. It makes sense to me.

I've had no experience with propane. But my best friend had a delivery service using Chevy pickup trucks with the 350 engine converted to propane. He would expect to get 300,000 miles out of an engine before ever having to put a wrench on the motor. He said when he did tear them down for a rebuild they would be clean inside as if they were new.

I think you're on the right track.

Just think add a 1 burner grill and you could keep your men working through lunch they can both cook and mow at the same time! Or you could have a second income of selling burgers and Dogs to neighborhood kids as you mow!

Knowing propane burns cleaner is great but I am sure DOT will get their hands involved in the transportation aspect. Haveing a limmit of propane avalable on equipment or trucks is next. Licensing of companies for handeling or storage of propane cylinders ect.. what could become a money saver might end up becomeing a money pit for owners. I'll stick with gas for now and see where this goes for future consideration.

We have 2 units on Propane and I am just about to do an install myself on Scag Tiger Cub. I got a protype mounting free so now I need a regulator and carb. The kicker for you may be the carb. My lawn shop convinced Kohler to make some carb after he had several made in an Austin shop. I will do the wiring but will need sensor to open the regulator. On my Tiger Cub they use the oil sensor. Keeping propane to the units is a little pain but we just bought more tanks.

What is the fuel comsuption per hour? What's the cost for fuel per hour? While I understand it burns cleaner with mowings dusty conditions does the oil appear cleaner?

A tank of 10 gallon runs 5.5 hours on the big briggs on turf tiger 61"and
propane cost me $2.79 per gal. I got no numbers on the 17hp sentar yet. The oil is definitely cleaner at the 50 hour point should go 100 easily. I use schaeffer syntheic 10w30. We got into propane by chance when we bought out another guys mowers. I get cheap propane by buying it from dealer where I do business for 35 years. Normal price is higher.

So does the engine run the same as it would with gas? What kind of modifications do you have to do to the engine? By the time its all said and done i think it will come down to what is more available. LP or gasoline.

How do you like running propane vs. gas?

Ill be honest propane sounds like a pain in the ass, I have ran forklifts before and the tanks are heavy take a while to get filled( not everywere here has propane) I can also see carrying around propane tanks in the bed of your truck to be a pain in the ass to!

Well you got to get used to dealing with filling the tanks. We bought enough tanks so we can go one week. I have only one tank on the machine so I keep a second tank in the bed of the truck. So far so good. I was reading about a TT problem with fuel pumps well I don't need to worry about that. We keep thinking that our city will enact ordiances that will force most guys to go to propane. On ozone action days you won't be able to run a gas machine. This winter I am going to install propane myself on a Tiger Cub that I just put a short block on so I'll see how that goes.

I just had my scag 52 vride converted. I signed a contract with my propane company that did the conversion. most of the conversion was paid by the propane assiociation of north carolina. And then I get a better price per gallon and they deliver the propane tanks to my storage unit. I have a 20 pound tank on the vride. Runs great!
Can anyone give me help on posting pics to my posts???

Have you been buying the oil straight from Jim Danklefs in case quantities and saving a little money?

i work for a company that installs Generac generators, the propane is vary reliable and clean power is lots stronger, motor will last longer, amsoil has a oil for the natural gas and propane units, remember gasoline is a liquid that cools in the motor, ur propane burns alot more btu's,a 990v twin is over 270,000btus full load 3600 rpm 2.5 gal per hr, so we tell customers that like a 720cc v twin 19hp 3600 rpm, will run 6-8 days full load on a 500 gal tank remember they dont really get 500 gals due to the make up on fuel it has to boil so probbly 350 gal area. Im a air cooled tech for generac.

um were still looking into it at work look on the amsoil website i think its 15-40 there is a stationary20-40 and a vehicular 15-40 last on motor oil page... if im not mistaken propane is a higher octain then gas if you can covert it..

only 15w-40 can be used in mobile motors LPG and LNG im waiting to see natural gas in this mowers but were gonna lose power, on gen sets we derate b/c the fuel is lower in btu's and dosnt have the qualitys like propane, life span on natural gas motors are good tho

This discussion has me worried that using Schaeffer synthenic 10w30 might not be adequate with propane in the big block Briggs?

I wouldn't worry about the oil. I worked at a ice arena and the zamboni used regular napa oil. They had 2 with 305 chev engines one was 20 years old and ran 15 min max at a time, that is hard on a engine.

remember the chevy has hydro lifters i think, your liquid cooled motors run constant temp air coolers are up and down in temp and there in 60-100+ degree days

There are two things that make engine oil dirty: Dirt from the air, and combustion byproducts. With propane, there are no combustion byproducts.

I just got a ferris is3100zp its made to run on propane. it uses a 32 briggs big block. It is saving me money down in central america cause gas is $12 and propane is $4. a gallon. The mower cuts fantastic ride is great and its really fast it has two 6 gallon tanks on it doesnt quite last all day. will buy 2 more tanks to take with it. I have a hustler z 60" with 27kohler. The ferris out works it and cuts super good in wet grass. I am getting another one this month. Oh I have a toyota v6 truck with over 230,000 miles on it that's been running on propane for its last 130,000 miles, this is the truck that pulls the mowers and work crew. No regulations down here, you can convert whatever you want and its on you. LOL.

I've look into getting into propane but after talking with the service techs at the dealers. They say they about the same dB, same amount of power, they run cleaner, and they'll be more expensive to maintain since if they break, it's newer technology and it'll take the techs more time to fix, meaning higher maintenance bills. As for the cost of operating it he couldn't really tell me alot but from what I've read it'll be more expensive to run. Just remember it's "greener." and by greener I mean more green you wont have.

I have talked to a rep and some owners on propane mowers and the owner says he is getting a $10.00 per day savings per mower on fuel. That would save us $300+ per week. As far as maintenance the only thing different is no carb, just the part to convert to propane which is minimal, everything else is the same as gas so repair cost should not change. We are going to demo one for a week and today is the first day. $300+ per week fuel savings plus the government kick back program makes it a no brainer for us.

No fuel filter and no chance of grass or debris entering the tanks...

I use a 60" Dixie Chopper Propane that has a Generac engine. I save a lot money and time using propane. The tanks are delivered to my business at approx. $20 each. The mower carries two 40lb tanks. When one runs out I just turn the other one on. At the end of the day I switch out the empty one in one minute. No spills, no need to worry if my guys are stealing. The engine runs great. I had one problem that Dixie Chopper fixed at no cost (three year warranty) and I believe improved my machine. The engine oil now runs through the propane converter which cools the oil.
A couple of years ago nobody was making lawn equipment that ran on propane and now they all are. I used to use lehr propane trimmers, but they were heavy and did not like being turned on their sides. They ran about 4 hours for each tank which cost two bucks.
Bottom line is you can save a lot of money and time by using propane.

Ask for Neil. Beam T60 Kits for Kawasaki Twins were about $315 including replacement carburetors or adapters. Ferrell Gas provided our cages and aluminum outdoor equipment tanks manufactured by Manchester and Worthington.

The conversion process is very straightforward and can be done in one to two hours.
