Less Labor

It’s a simple propane cylinder switch out—no trips to the gas station. Your propane supplier sets up and maintains your fuel supply so you don’t have to.

No Fuel Spills

Propane is a closed, secure fuel system.There’s no fuel spillage or pilferage.

CLEANER Operation

Propane has minimal emissions (EPA Clean Air Act) so engines last longer and require less maintenance (less oil and filters). Your crew and community benefit from a clean operation.

Frequently Asked Questions

How does a propane mower work?

A propane canister is attached to the mower, connecting it to the engine through a fuel line. While the lawnmower is running, the propane gas heats up and combusts, creating the energy necessary to run the mower. There is also a pressure regulator that keeps the propane’s pressure in the canister at the appropriate level.

Are propane mowers worth the conversion?

Propane is a great fuel source for lawnmowers because it burns very efficiently, and using propane is better for the environment, and will save you money on fuel and maintenance. A propane mower will consume fuel more efficiently, it will last longer between fill-ups.

Are propane mowers safe?

Propane is nontoxic, has a lower flammability range than conventional gasoline, and odorized for easy detection. The containers are equipped with safety devices, including pressure-relief valves, shut-off valves that detect fuel line ruptures, and overfill protection. As well as being constructed from carbon steel and are 20 times more puncture-resistant than conventional gasoline and diesel tanks. 

Ken Dykstra, product strategy manager for Kawasaki Engines said –  “Those propane tanks are far more robust than any gasoline tank and don’t have to vent like a gas/diesel tank have to. It just takes education and familiarity with propane to show it’s safe on a commercial mower.”

What size propane tank goes on the mower?

The propane tank that is typically used on a mower is a 33 lb. cylinder; they hold just over 7.5 gallons of propane.

How long can I mow on a single tank of propane?

Due to the size of the propane cylinders, mowers can run from three to six hours per single fill. Some crews have dual-cylinder mowers, allowing for even longer run times.

What operator safety issues had to be addressed and/or overcome?

There are relatively no added safety concerns created by running and engine on propane compared to gasoline. The only added safety measure put in place was instilling a lock-off switch in the pressure regulator that allows the engine to cut off fuel delivery to the injection system if pressure becomes low.  

Is propane a clean alternative fuel?

Yes, the EPA considers propane a clean alternative fuel under the Energy Policy Act of 1992.

How is propane cleaner than gasoline?

Propane cuts significantly more NOx (Nitrogen oxides) and greenhouse gas emissions compared to diesel and gasoline. The EPA considers propane a clean fuel. Propane is known as the number one alternative fuel around the world.

Frequently Asked Questions

Can you convert a gas mower to run on propane?
How much does it cost to convert my lawn mower to propane?

A mower conversion starts out about $800-$1500 approximately.

Is propane hard on the mower engine?

No, a propane mower engine runs on gaseous (vapor) propane like a barbecue grill, thus doesn’t create carbon build-up often seen in gasoline engines – meaning longer engine life with fewer maintenance issues. 

Is there a reduction in horsepower with the EFI/propane vs. gasoline powered units?

Engines fueled by gaseous propane typically do not produce as much hp as a gasoline fueled engine of equivalent configuration.  A general rule of thumb is that a carbureted propane engine will produce 10% less hp than an equivalent carbureted gasoline engine.  A propane EFI system however, is able to substantially reduce this loss of hp. 

What is the average oil change interval for a propane mower?

On average, you should change your oil every 300 hours using the recommended oil and filter for a propane mower.

Is there funding available to help me make the transition over to propane?

Yes, the Ohio Propane Gas Association offers a $1,000 rebate to Ohio residents that are either buying a new propane mower OR converting their mower to propane.

Infrastructure Options

Propane has convenient refueling options for small, medium, and large mower fleets. Typically small to medium sized fleets set up a cylinder exchange where cylinders are replaced by their propane supplier on a regular basis. Larger operations often work with their propane supplier to install on-site dispensing stations at their business. Contact your local propane supplier to discuss which option is best for you.

Onsite Standard Private station

  • Best for a fleet of less than 5o 
  • Onsite 1,000 – 3,000-gallon tank

Option 1: Propane Supplier Owns Infrastructure

The fleet is responsible for site preparation: crash protection and electrical.

Cost for Fleet: $1,500-$15,000 (site preparation)

Option 2: Fleet Owns Infrastructure

The fleet will need to account for purchasing the propane tank, pump, motor, and dispenser.

Cost for Fleet: $20,000-$60,000 (infrastructure) + $1,500-$15,000 (site preparation)

Onsite Advanced Private station

  • Best for 50+ vehicles
  • Larger gallon tank, canopy & multiple dispensers

Option 1: Propane Supplier Owns Infrastructure

The fleet is responsible for site preparation: crash protection and electrical for a two-dispenser setup.

Cost for Fleet: $5,000-$75,000 (site preparation)

Option 2: Fleet Owns Infrastructure

The fleet is responsible for site preparation: crash protection and electrical for a two-dispenser setup.

Cost for Fleet: $60,000-$225,000 (infrastructure) + $5,000-$75,000 (site preparation)

Private or Public Network

Fleets with limited space, or fleets needing more fueling locations along their routes can take advantage of this option with no infrastructure investment. Network refueling stations are accessible 24/7 through a card lock system.

If a network is not currently available in your area, a propane supplier may create one for your fleet, if it’s large enough. Alternatively, multiple fleets can team up to provide adequate load for requesting a refueling network.

Frequently Asked Questions

How do you refuel propane-powered mowers?

Propane has convenient refueling options for small, medium, and large mower fleets. Typically small to medium sized fleets set up a cylinder exchange where cylinders are replaced by their propane supplier on a regular basis. Larger operations often work with their propane supplier to install on-site dispensing stations at their business. Contact your local propane supplier to discuss which option is best for you.

What is the storage life of propane?

Unlike diesel’s one-year shelf life and gasoline’s 3 to 6 month shelf life, propane can be stored indefinitely so it is highly effective and convenient for both residential and commercial sectors.

How do I start my own private fueling station?

Contact your local propane marketer and they can offer an inexpensive lease of the tank, pump, and dispensing equipment in return for a fuel supply contract or they can contact an infrastructure manufacture to help you purchase your own fueling equipment and shop around for propane fueling prices.

Is there any storage and fueling considerations when it comes to propane?

Landscapers must be aware of local ordinances for the storage and transportation of propane tanks. Check with your local propane distributor and they should be able to guide you through transporting your mowers with propane tanks on them.
