Construction Equipment Outlook: Bobcat 331 and 334 Excavators



When you’re looking for construction equipment to move a lot of earth quickly, you need an excavator. Excavators are powerful machines that are essential for construction projects all across the country. These machines come in three sizes: compact excavators, mid-size excavators, and large excavators.

American-based Bobcat Company (a Doosan company) has produced construction equipment like the Bobcat 331 and Bobcat 334 for over 70 years. These mini excavators have Kubota engines, providing you with the power you need to get the job done. Let’s take a closer look at the Bobcat 331 and Bobcat 334 specifications. We’ll look at some of the relevant numbers, like size, speed, capacity, and so on. Then we’ll talk about the different attachments available for your mini excavator, as well as some information about the final drive travel motor in these models.

Bobcat 331 Compact Excavator

The Bobcat 331 mini excavator is a powerful and efficient machine that is a staple within the construction sector. These compact excavators come standard with rubber tracks and a long arm, as well as an auxiliary hydraulic system. The Bobcat 331 mini excavator is more versatile than a skid steer. It can be equipped with a number of different attachments thanks to the built-in quick coupler and can be turned into a loader by attaching a dozer blade. Your Bobcat 331 also comes with soft-touch joystick controls, allowing you full control over your equipment.

Bobcat 334 Mini Excavator

The undercarriage is also very similar to the Bobcat 331, and it comes with an included quick coupler and ability to convert from a backhoe to a loader with a dozer blade attachment. Also like the Bobcat 331, this model comes with soft-touch joystick controls to prevent fatigue. Overall, this excavator is very similar to the Bobcat 331, except this mini excavator has more power.

Excavator Attachments

Unlike a skid steer, both of these compact excavators can accommodate a number of different attachments to function as a backhoe, a loader, and more. For instance, you can attach a hydraulic thumb, which converts your excavator from a digger into a material handler.

There are also a number of different dozer blades available to accommodate whatever task you’d need your loader to perform. Finally, you can purchase and install a ROPS (roll over protection system) cage to ensure your operators stay safe.

Final Drive Travel Motors

Again, make sure your machines are equipped with fully functioning Bobcat final drive travel motors for maximum performance. If you’re searching for final drive motors and want to emphasize Quality, Value, and Service, there is only one place to go: Mini Final Drives.

One more note about the Bobcat 331 and 334 excavators — when it comes to Bobcat final drive travel motors, final drive gear oil should be checked at least once after every 100 hours of operation or once a month. Additionally, Bobcat final drive travel motor gear oil should be changed once a year.
