operating cost savings

If you’re thinking about converting your commercial lawn mower to propane, don’t forget to take into consideration total operating costs. Here are 3 ways that landscape contractors are finding cost-savings:

– Virtually eliminating fuel spillage
– Virtually eliminating fuel leakage
– Virtually eliminating fuel theft

golf courses and the use of propane

According to a recent article from Golfdom, (an online magazine whose primary readership are superintendents-the people who manage and maintain golf courses), the Propane Education and Research Council (PERC) has teamed up with 8 golf courses across the country to test propane-powered lawn mowers on their grounds. These 8 courses are currently recording performance data, which includes fuel savings, during their trial period, and have reported favorable results thus far. Jeremy Wishart, PERC’s deputy director of business development, stated, “Many of the superintendents are already reporting significant operational cost savings with the propane equipment—some in the thousands of dollars range—compared with their gasoline and diesel-fueled equipment.”

One of the courses chosen to participate, located in Tacoma, WA, is a course that has earned the Audubon International’s Cooperative Sanctuary certification. This is an award-winning education and certification program that helps golf courses protect the environment and preserve the natural heritage of the game of golf. It’s easy to see why propane-powered mowers are an ideal choice for this course, since propane uses less energy, creates less air pollution, and cause the mowers to run at a lower cost.

One of the concerns the golf courses had regarding the use of propane-powered mowers, was that of power loss. This concern was tempered quickly after the trial period began, when the mowers did not have a negative influence on power saving. What we’ve learned from this trial thus far strongly suggests that propane-powered mowers greatly benefit companies.

When companies use propane-powered mowers, there are a lot of benefits from the tanks alone. If a company is using gas or diesel, there can be plenty of confusion between the tanks. Since propane is a sealed tank, it is impossible to confuse it for another type of fuel. Propane tanks are made from steel or aluminum, and are therefore 20 times more crash resistant than plastic gasoline tanks, plus these sealed tanks also prevent spillage and fuel theft.

The benefits of its tank aside, propane is also a nontoxic material, meaning it is not harmful to water, air, or soil. If propane leaks, it doesn’t puddle on the ground like gas or diesel and kill the grass, but instead safely vaporizes and dissipated into the air.

Additionally, there are lower maintenance costs when using propane as your primary fuel source. Propane is less expensive than gas or diesel and if you are located in an area that has ozone action days, propane mowers are safe to run on those days. Furthermore, more than 97% of propane that is used in the United States comes from U.S. soil.

These benefits have always been apparent, but thanks to this recent study, we’re learning even more about the advantages of propane as a fuel source. If you are thinking that propane might be the answer to your high fuel costs and want to shrink your carbon footprint, we have conversion kits for the most popular gas mowers out there. Converting to a new fuel source has never been easier; contact us to start saving money on fuel today!

8 common questions regarding converting to a propane mower

Question 1:

A number of questions, concerns, and honestly, rumors have been flying around regarding propane conversions on commercial mowers. Like most things in life, there is a right way to do things and a way that, if we cut corners or leave out a few steps, we might save a bit of time initially, but we don’t necessarily get the results that we want.

We receive questions from time to time regarding problems with other propane conversion kits from other suppliers. And we are surprised at some of the stories that we hear from other folks out there—folks trying to do propane conversions.

Here’s one call we received recently:

“Propane conversions for mowers seem pretty difficult to install. I don’t know what to do about all the parts in the box. I have some fittings and parts left over. Are they really necessary?”


Response by: Todd Hendrix, President, Hendrix Industrial Gastrux/Progressive Fuel Technologies

 “All Hendrix propane conversion kits are built to fit the specific engine used on the mower. All wiring, cabling, tubing is cut and fit, with all connectors securely attached with heat-shrink tubing to protect from the environment. Each component and part is ready to attach and secure to prepare for final adjustment. An easy-to-use Installation Manual gives you step-by-step instructions that if followed, will provide optimum power, performance, and fuel economy. It is also essential that the air/fuel ratio and final adjustments be made and adjusted with a proper exhaust analyzer.”  

Moral of the story:

  • Don’t cut corners
  • Don’t buy bargain kits
  • Use kits made specifically for engine (no one-size-fits all)
  • Must use proper calibration procedure
  • Must use CO gas analyzer for final adjustment



cutting costs the propane way-8 reasons to convert

Just because oil prices have lowered, doesn’t mean you shouldn’t convert your commercial lawn mowers to run on propane. Here are 8 good reasons to convert:


  • lower operating costs

Propane is still less expensive than gasoline. It’s typically 30%-40% less expensive

than gas. Also with cleaner burning propane, service intervals can be increased

because of decreased carbon buildup and no gumming of engine parts from

ethanol-based fuels.


  • proven performance

Properly tuned to the manufacture’s guidelines, propane mowers offer the same

power and work capabilities as gasoline-fueled commercial mowers. Propane mowers

offer approximately the same length of mowing time per fuel cylinder, and even

better performance on steep slopes because vapor fuel will reach the engine even

when the mower is at a steep tilt.


  • fewer emissions

compared to gasoline, propane exhaust creates 60%-70% less smog-producing

hydrocarbons, yields 12% less carbon dioxide, about 20% less nitrous oxide, and as

much as 60% less carbon monoxide. It cuts emissions of toxins and carcinogens like

benzene and toluene by up to 96%.


  • easy on-site refueling options and less down time

the on-site bulk tank offers the convenience of your own propane filling station, or

the propane company will come to your facility and fill empty tanks. These options

eliminate time consuming trips to the gas station.


  • reduced fuel spillage and theft

using propane virtually eliminates fuel spillage, leakage and theft.


  • abundant fuel supply produced in the United States

propane is an affordable, clean, America-made fuel.


  • Lower maintenance costs

With cleaner burning propane, service intervals can be increased because of decreased carbon buildup and no gumming up of engine parts from ethanol-based fuels.


  • incentive programs

The Propane Education Research Council (PERC) has a $1,000 incentive program for

aftermarket conversion kits for commercial lawn mowers. There are also state

propane gas associations that have incentive programs. Check with your state to find

out if programs are available.


Use the Propane Calculator tool to find out how much money converting to

propane could save your business. Simply input a few numbers and the calculator will

show how you the cost savings of a propane-powered mower compared to those that run

on gasoline.


Cutting costs the propane way is simple, but when  you see the cost savings with your

own eyes, it becomes impossibly hard to resist. See for yourself here.







Lawn mower double money back incentive program

I am excited to announce the Propane Education & Research Council’s (PERC) double incentive program for lawn mowers.

Starting October 1, 2014 and running through March 31, 2015, the Propane Education & Research Council will be launching an exciting, limited-time promotion for the Propane Mower Incentive Program. The incentive program will feature a “Double Your Incentive” opportunity for applicants. During this limited time, the program will reward landscape contractors with $2,000 per qualifying new propane mower purchase or $1,000 per qualifying mower conversion. In return, participants provide feedback and performance data for one mowing season.

This is a great opportunity not only to save you money, but also for PERC to gain important performance data. With October upon us, and the mowing season in some parts of the US winding down, now may be the perfect time to start thinking about next year’s cutting season. If you are thinking about how you can cut down on costs, converting your mower to propane may be the answer. With this PERC program combined with your state’s incentive program, (contact your state’s propane gas association for incentives they may offer) the cost of a conversion could be minimal. For example, if you convert your mower through the PERC program in Illinois you could receive $1000 along with the Illinois Gas Association program rebate of $750 per mower. (The combination of the two rebates is more than the cost of our kit in most cases). The funds are available on a first come first serve basis—so don’t delay.

It has been said from customers that have purchased our kits that the instructions were easy to follow and the kits were easy to install. Customers also noted that the kits came completely assembled, with minimal adjustments needed, and that all components were received promptly. We also offer training classes at our facility or your own if that is something you may be interested in.

If you think this opportunity may be of interest to you, but have more questions than answers, please call or email Hendrix Progress Fuel Technologies and one of our technicians will be happy to answer any questions you have.
