Engineered to minimize the risk of hydraulic overheating when mowing and mulching, the new SK Rooftop Cooler from Diamond Mowers is the latest addition to the company’s line of skid-steer attachments and accessories. Exclusively compatible with select Bobcat R Series and John Deere models, the specialized cooling system mounts to the roof of skid-steers and CTLs.
Diamond’s rooftop cooler provides operators with cooling capabilities to help reduce downtime and increase operating hours per day. With a heat rejection capability of 140,000 BTU per hour, the cooling system enables the carrier to maintain optimum hydraulic temperatures.
“Mowing and mulching applications are among the most demanding on a hydraulic system, with high loads accompanying high heat,” explained Dan Stachel, executive vice president of Diamond Mowers. “If this heat is not dispersed effectively, it can lead to fluid degradation, reduced performance, overheating and even equipment failure — all of which can negatively impact productivity. To help keep operators up and running, we built a solution that ensures optimal cooling performance and extends the life of expensive hydraulic components like valves, pumps and motors.”
Keeping the system cool are two, 12-inch auto-reversing electric fans and a heavy-duty, laser-cut lid promotes adequate airflow and protects internal components from branches and debris.
“This system works by using a fan to draw air through a cooler, which cools hydraulic fluid as it passes through,” added Stachel. “The cooled oil is then recirculated back into the system to ensure the equipment remains operating within an optimal temperature range.”
Diamond Mowers’ new rooftop cooler can be purchased individually or as part of a Forestry Package combined with Command Couplers and a Safety Glass kit. Featuring an exclusive threaded design to improve attachment performance, reduce downtime and enhance security, the Command Couplers create a strong connection that delivers superior resistance to repeated pulling and pushing of hydraulic lines and eliminates the need for hydraulic coupler replacements.
