Bobcat says it has introduced improvements to the undercarriage of its compact track loaders, with a new solid-mount and optional “Roller Suspension” system available for the following models: T550, T590, T630, T650, T740, T750 and T770.
Dual-flange front idlers now ride on the rubber track’s roller way. These new front idlers, along with wider rollers, help reduce vibration, Bobcat says, not only improving operator comfort but also reducing wear on the inside of the track. Single-flange idlers are still found on the rear of the machine to help minimize de-tracking.
The optional Roller Suspension system has also been changed. It also incorporates the dual-flange front idlers and wider rollers, as well as mono-leaf springs, for smoother action. Bobcat says the front idlers have been relocated to enhance machine operation.
A horizontally mounted tension cylinder opens more room between the carriage and track for easier cleanout. In the improved design, Bobcat says, the undercarriage is sloped on both sides to shed material, such as sand, dirt, mud and debris more effectively. Also, a raised cutout between the rollers allows for easier cleaning.
Bobcat says ground clearance at the center of the undercarriage has been improved by up to 29 percent, enabling the machine to travel through mud, sand and other soft soil conditions more easily. Meanwhile, clearance at the rear of the machine has been increased, enhancing the loader’s ability to travel over curbs and other obstacles without catching on them.
Depending on the model, Bobcat says operators will see an increase in fuel capacity of up to 45 percent with the improved undercarriage.
