Machine History and Background
The Bobcat 873 represents a significant evolution in Bobcat’s loader lineup, marking the transition towards larger frame sizes equipped with vertical lift path designs. This design enhancement improved lift capacity without increasing overall machine weight, offering a powerful solution for lift-and-carry tasks in construction and industrial applications. The 873 emerged in the late 1990s as part of the G-Series, building on Bobcat’s legacy of skid steer innovation dating back to the 1960s.
Engine and Power
Given the machine's history of use in challenging environments such as fertilizer factories, rust and corrosion can affect components, especially final drives and hydraulic lines. Maintaining cleanliness, especially around pumps and hoses, is critical:
New owners transitioning to Bobcat from other skid steers often appreciate the 873’s performance balance, though unique maintenance challenges may arise:
The Bobcat 873 skid steer loader stands as a durable, mid-sized machine optimized for lift and carry tasks in diverse worksites. Its robust Kubota engine, vertical lift design, and versatile hydraulic system offer performance and productivity. Owners should proactively address rust and maintain hydraulic components to ensure longevity and reliable operation on the toughest jobs. With proper care, the 873 continues to be a valued tool for contractors transitioning into Bobcat machinery.

Engine and Power
- The 873 is typically powered by a robust engine around 73.5 horsepower, often a Kubota diesel, delivering reliable torque and efficiency suited for demanding job sites.
- Engine displacement is roughly 166 cubic inches (2.7 liters), providing a balance of power and fuel economy for mid-sized skid steer applications.
- Operating weight is approximately 6,885 pounds (3,123 kilograms), offering stability and maneuverability.
- Its length measures about 11.7 feet, width near 6.1 feet, and height close to 6.5 feet, ideal for both confined and open worksites.
- Tire specifications are commonly 12x16.5, 10-ply rating, chosen for durability and traction across various terrain types.
- Rated operating capacity (ROC) is roughly 2,300 to 2,400 pounds depending on configuration, enabling efficient material handling.
- Hydraulic flow ranges vary: standard models feature about 18 gallons per minute (68 liters per minute), suitable for general loader attachments, while high-flow options (up to 30 gpm) accommodate more demanding hydraulic tools.
- Travel speed maxes near 8 mph, balancing work pace with control.
Given the machine's history of use in challenging environments such as fertilizer factories, rust and corrosion can affect components, especially final drives and hydraulic lines. Maintaining cleanliness, especially around pumps and hoses, is critical:
- Applying rust inhibitors or penetrating oils can prolong component lifespan.
- Regular inspection of hydraulic hoses is necessary to prevent leaks and failures; when replacements are needed, careful routing avoids damage from rubbing or contaminants.
- Serial number gaps due to wear or hose contact can complicate parts identification, highlighting the importance of thorough service records or consulting specialized dealers.
New owners transitioning to Bobcat from other skid steers often appreciate the 873’s performance balance, though unique maintenance challenges may arise:
- The vertical lift path enhances lift performance compared to earlier radial lift models.
- Kubota engines are generally praised for durability but require proper maintenance.
- Familiarity with Bobcat-specific hydraulic and mechanical systems is valuable for troubleshooting and repairs.
- Vertical Lift Path: Loader arm design offering a straight upward lifting trajectory for improved load control.
- Rated Operating Capacity (ROC): Maximum safe load the machine can carry at full reach.
- Hydraulic Flow: Volume of hydraulic fluid delivered, influencing attachment speed and power.
- Final Drive: The gear system transmitting engine torque to the wheels/tracks.
- Penetrating Oil: A lubricant used to loosen rusted or stuck parts and protect against corrosion.
