There are over 40 million acres of lawn across the United States, made up, primarily, of residential lawns, roadsides and golf courses. While many Americans maintain their own lawns, a growing number of contractors, landscapers and lawn care consultants are hired to do the job. For these working men and women, the more lawns maintained during the day, the more successful their businesses become. To mow faster and longer, specialized mowers are used to mow more grass with more precision.Transmissions: a driving force
As with any machine, a commercial mower’s primary function is to make a task easier, in this case, mowing grass. Via a network of hydraulic, mechanical, electrical and chemical processes, a mower is propelled by a simple push or pull by the operator. One such process is performed by transmissions, located near each wheel of the mower. These integrated drive systems pull power from the engine and create the torque and speed required to get a mower moving and to keep it moving. A combination of a hydraulic pump and motor can also be used if space allows.
For a smooth and comfortable ride, a quality drive system is required. Otherwise, the mower can begin to cog when the drive is placed under too large a load. Cogging can ruin the user experience and potentially result in a stuck mower. Nothing will set an operation back like stuck equipment.
Cogging can create problems for a user as the mower starts to move, but once the mower is in motion, the drive system’s job is not done. To maintain a fast, effective cut, a drive system must provide consistent power throughout a job. UCLA legend John Wooden said, “Be quick, but don’t hurry”. He used this sentiment while coaching his championship basketball teams, but the same can be echoed in the turf industry. Speed is important, but an ineffective cut, caused by an inferior drive system, wastes time.The gold standard
Parker’s HT Series is the pinnacle of drive systems in the turf industry. By coupling a Torqmotor and variable displacement pump, the HT Series delivers more power to the cutting deck, decreases fuel cost, and eliminates cogging. When used with Parker formulated HT-1000 transmission oil, oil change intervals are increased to 1000 hours; 2x longer than competitive drive systems.

The OEM landscape is continuously transforming. In a service industry that once focused on the tactical side of product function, the new shift now emphasizes on how to become the strategic revenue generator and competitive differentiator through the utilization of modern technological systems, such as IoT.
This pressure enhances the competitive environment, putting OEMs on a constant mission to expand their offerings and provide the best in class equipment to their customers to build new partnerships and enhance their current relationships. The key metric of this strategy is ensuring customer satisfaction. But we cannot simply neglect the importance of increased productivity, efficiency, and achieving appropriate returns on investment (ROI).
According to Bain’s projections, 6.8 million connected heavy construction machines will be shipped between 2018 and 2025. It is clear that the future largely depends on the Internet of Things (IoT) to power further data collection and analysis and overall innovation in the field. Yet this investment into IoT, like any strategic investment, must be assessed and the ROI is a critical measure before determining whether your organization should invest.
The top performance indicators for measuring the success of IoT for heavy equipment OEMs are:
Let’s take a look at how IoT can enhance an OEM's performance in these specific areas and how they connect back to the ROI attainment.
In today’s day and age, one of the most crucial aspects of obtaining an exceptional customer experience is to make sure that you are valuing and prioritizing the customers’ time. Predictive service helps address this problem. By utilizing IoT to forecast when a piece of heavy equipment may need repairs or service, even under unexpected circumstances, OEMs can better manage and accurately schedule downtime on machinery and equipment, ultimately delivering a better service experience to customers.
Better servicing not only leads to more satisfied customers, but it also provides operational gains. The benefit of an IoT solution for heavy equipment is that it helps the user better understand exactly what the problem is that needs to be examined from a remote location. This gives the technician a heads up and ensures they will have the right equipment, parts and skills to solve the issue and get things up and running again faster.
Providing accurate updates to service technicians also smooths over the process of meeting compliance requirements for companies with service level agreements. The embedded IoT sensors not only help with the predictive servicing on machinery, but they also enable automatic reporting on asset health and communicate when thresholds have been reached. This feature dramatically improves the chances of meeting SLAs.
In addition to remote monitoring, predictive maintenance detects possible failures ahead of time, so an OEM can take corrective action at the right time to avoid unscheduled maintenance and unplanned downtime, thus mitigating project risks and reducing costs. For an OEM, predictive maintenance data is useful in terms of quality issues. An OEM can track historical failure data so corrective action can be put in place to avoid unnecessary downtime for additional customers due to unforeseen quality issue.
Combining, storing, and analyzing heavy equipment data is the kind of ‘deep learning’ required to take predictive maintenance to the next level. Data gathered on a piece of heavy machinery allows OEM to go from predicting when a known failure mode might occur to preventing it. This new learning is then incorporated to improve engineering knowledge that in turn helps build better models. Taking this to the next level, as we better understand failure modes and their predictors, and collecting even more precious data on a per machine basis, can enable OEMs to model performance for individual machines in terms of operator utilization and environmental impact.
In addition to improving engineering and design concepts, OEMs can leverage data from an IoT solution for heavy equipment to create different types of equipment, with less simulation and modeling required. Using the real data from existing infrastructure, the options for finding new designs or even new uses for equipment can lead to new markets and new product lines for an OEM. This presents a massive opportunity for the OEM to ensure that they stay ahead of the competition.
OEMs realize that connected off-road equipment can help their customers reduce costs, increase productivity, and improve safety. These services not only add value for an OEM customer, they also increase brand loyalty, as other brands of equipment are not integrated with an existing IoT solution. Parker offers a customer-centric IoT solution, Mobile IoT, to meet the specific requirements of heavy equipment OEMs. As a result of implementing Parker’s Mobile IoT, OEMs are able to generate additional revenues not only from its data-driven offerings, but also from its core business through increased equipment sales and aftermarket services.
For OEMs, building an IoT platform in-house can be costly as well as require years of development. Working directly with Parker enables OEMs to benefit from comprehensive technology integration and data analytics expertise to create valuable machine designs for customers without the cost or risk of building out a solution in-house.

When it comes to hoses and cold weather performance, force to flex is not as important as actual hose construction. In harsh winter temperatures, hose construction materials can be a major contributor to hose failure. Over time, cold temperatures and UV rays dry out the core and jacket of a hose. This embrittlement of materials results in cracks. Cold sluggish fluid or low temperature fluids not compatible with the core materials can also add stress and cause damage.
Parker engineers have been working closely with machine and vehicle designers for more than 30 years on the selection of optimal hoses. The added stress of colder environments, led them to design the new, low-temperature hydraulic hoses which operate in temperatures as low as -70°F/-57°C with pressures operating up to 5,000 psi (345 bar).
This new technology for low-temperature hydraulic systems has proven itself in a variety of different low and high-pressure applications, especially forklifts and aerial lift equipment or used in commercial freezers in harsh winter conditions. Applications range from low pressure fluid transfer, over-the-sheave, and steering lines to high-pressure hydraulics.
Parker low temperature thermoplastic hoses are built with a proprietary blend of materials specifically formulated to withstand repetitive flexing in cold temperatures. The 563LT and 594LT offer the same abrasion resistance as Parker's standard hose but decrease component downtime in low temperatures. The ability of these hydraulic hoses to perform repetitive flexing in a cold environment opens a new range of possibilities for the industry while increasing product life. For the customer, excelling in cold climates means reduced change outs, reduced warranty maintenance and replacement costs.
Each hose is reinforced with either synthetic fibers, steel wire, or a layer of each, which enables assemblies to handle up to 5,000 psi (345 bar) working pressure (depending on hose selection). Available core tube options have a low coefficient of friction while maintaining excellent flexibility and a premier, abrasion resistant cover. This maximizes efficiencies and minimizes pressure losses to ensure long service life.
Temperature deformation of the product does not affect the assembly’s chemical compatibility, technical performance or functionality. In addition, hose covers are durable and insensitive to UV or ozone exposure and thus, resistant to environmental stress.

Battlegrounds Coffee is a small, community-oriented coffee shop in Haverhill, MA. The owners were challenged to find a more efficient and consistent way to deliver Nitro Coffee to their customers.
Nitro coffee is the new smooth brew
According to Battlegrounds Coffee, Nitro coffee is the new trend.
It has a soft smooth mouthfeel. It’s like sipping on a Guinness. It gives the sensation that you’ve added cream to it but you haven’t. It looks fantastic poured and cascading in a glass. Nitrogen gas enhances some of the complex coffee flavors that you find in our blends and roasts at Battlegrounds Coffee. Prior to using the generator, we were using pre-charged food-grade nitrogen tanks.
"Tanks were the most difficult aspect of making and maintaining nitro coffee. The pressure gauges on the regulator were faulty indicating you had more nitrogen that was really left. As owners, we would get calls in the middle of the day saying 'Hey, we are out of nitrogen!'
For us, it was a hassle getting those tanks refilled. We had to drive to the local welding shop. We change out the tank 3-4 times per week so you had to assure that was done right and that there were no leaks. It wasn’t an efficient system and was becoming a hassle. The supplier was charging more than $50 per tank for food-grade nitrogen so my payback was very quick."

Nitrogen Generators with on-board compressors for low flow applications provide safety, savings, and convenience.
Parker nitrogen generators completely eradicate the danger, inconvenience, and high costs of truck delivered nitrogen. The hassles of changing high-pressure tanks and the routine interruption of nitrogen supply are eliminated. They offer long-term cost stability by eliminating vendor price increases, contract negotiations, long term commitments, transportation issues and hazmat charges.
Once installed, a continuous supply of high purity nitrogen is available within a few minutes of startup. Nitrogen, unlike CO2, imparts a small bubble that creates an attractive cascade down the side of a glass. More importantly, the small size of the nitrogen bubble creates a smooth, creamy finish on your palate. Consumers report that it is even sweeter than conventional iced coffee.
Watch the video interview with Battlegrounds:
Meeting the needs of retail coffee establishments
Building on Parker’s history of over 35 years of producing Nitrogen Generators for beverage dispense, we are pleased to offer a nitrogen gas generator specifically designed to meet the needs of retail coffee establishments. Parker Nitrogen Generators eliminate the danger, inconvenience and high costs of truck delivered nitrogen. There is no need to rely on an outside supplier. The hassles of changing high-pressure tanks and the routine interruption of nitrogen supply is completely eliminated.
Parker Nitrogen Generators are also good for the environment because delivered nitrogen is manufactured using an energy-intensive process and then distributed in smog generating trucks. Parker generators offer long term cost stability by eliminated vendor price increases, contract negotiations, long term commitments, tank rental fees, delivery fees and hazmat charges. Once the generator is installed, a continuous supply of high purity nitrogen is available within a few minutes of startup.
Cold brewed coffee may be enhanced with nitrogenation. Nitrogen becomes infused into the coffee, much like a nitro beer. Nitrogen, unlike CO2, imparts a small bubble that creates an attractive cascade down the side of a glass. More importantly, the small size of the nitrogen bubble creates a smooth, creamy finish in your mouth. Consumers even report that it is sweeter than conventional iced coffee. Imagine the reaction of your customers to a creamy slightly sweet coffee without the need for added cream or sugar! Parker nitrogen generators are ready to operate as delivered with carefully matched components engineered for easy installation, operation and long term reliability. The generators are free-standing and housed in an attractive cabinet with casters.
The Parker DN-6NA Nitrogen Generator is designed to provide a constant supply of nitrogen gas, at a pre-selected purity, flow, and pressure. The system uses proven Pressure Swing Adsorption (PSA) technology with a Carbon Molecular Sieve (CMS) to separate N2 from the atmosphere and deliver it at high purity. The installation consists of simply connecting the plug to a standard outlet and connecting the nitrogen outlet to your coffee dispenser.
The onboard compressor means that there is no need to connect to a source of compressed air. Simply turn it on, and the air is then prefiltered, compressed, and passed through a 0.01 micron filter rated at 99.99%. The air is then passed through the CMS separation bed which captures the oxygen, creating a stream of high purity nitrogen. Lastly, the stream of nitrogen is passed through a sterile grade filter rated at 99.99999+% at 0.01 micron and then sent to the coffee dispenser. The CMS bed is regenerated to remove the captured oxygen and the cycle repeats.Nitrogen generator package includes
"The Parker DN-6 provides nitrogen without any interruption. It’s always ready. Saved us at least four man-hours per week. It is awesome! We use nitrogen to push Kombucha too. Plug and play. It’s always working and saves us a lot of time. We also pour wine and we keep the wine bottle purged with nitrogen to keep it fresh. We are also looking at using it to pour our beer too.”
— Sal DiFranco, Battlegrounds Coffee
"We were always fighting with the tanks to work properly to pour the perfect pour for a nitro cold brew. Since we’ve had the nitrogen generator it has been easy breezy. With a generator, you don’t have to worry about it. You set and forget. We never have to tell customers 'Sorry we aren’t pouring today.' The pour looks great, tastes even better.”
— Dana, Battlegrounds Coffee
