Bobcat planetary augers expand lineup with increased torque and digging depth

Bobcat Company — the leading designer and manufacturer of attachments for compact equipment — introduces the Bobcatฎ 35PH and 50PH planetary drive augers. The new units are compatible with approved models of Bobcat skid-steer loaders, compact track loaders, all-wheel steer loaders and compact excavators.

Expanding the lineup of Bobcat augers, these units are designed with a high-torque gearbox, allowing them to deliver more power for difficult installations at deeper digging depths and for working in tough conditions such as rock, clay, coral and frost. Greater torque can be especially beneficial to excavating, grading and site development contractors, as well as beef cattle producers and landscape professionals installing fence, anchors and screw pylons.

Both the 35PH and 50PH planetary augers are 11.5 inches wide and 39.6 inches long and can dig to depths of 73 inches without an extension. An optional adjustable inner extension is available to increase the digging depth an additional 48 inches. The 35PH planetary auger provides 4,177 foot-pounds of torque at 3,500 psi, while the 50HP offers 5,291 foot-pounds of torque at 3,500 psi.

Increased digging performance

With the additional torque that a planetary drive delivers, it can dig deep holes more efficiently to outperform a direct drive auger in tough applications. Featuring an efficient displacement design, the 30PH and 50PH augers have smaller drive housings — less than 12 inches long. This smaller housing allows it to follow the bit all the way into the hole to achieve deeper depths. The two-piece shaft design ensures maximum side load ratings without increasing the load on bearings, protecting productivity and uptime.

The longer heavy-duty and rock bits also contribute to deeper holes. At 61.5 inches long, these bits are at least 12 inches longer than current Bobcat auger bits. The new PH auger also has a longer and stronger 2.5-inch hex output shaft to handle the increased torque output.

Versatile mounting system

The 35PH and 50PH planetary augers are designed with a versatile mounting system that helps Bobcat operators switch the auger between loaders and excavators. Bobcat skid-steer loaders, compact track loaders and all-wheel steer loaders can accept the planetary augers with the Bob-Tach™ attachment mounting system. The planetary augers can be fitted to the compact excavator mounting frame using the Bobcat X-Change™ mounting system.
