Operator Comfort
The LED work light package ensures excellent visibility in low light conditions.
Serviceability
The TB257FR forward tilting cabin provides access to control valve, slew motor, swivel joint and engine.
Durability
The TB257FR was built with a heavy gauge steel k-frame, oversized slew bearing and ring gear to provide an outstanding operating platform.
Performance
The TB257FR comes with a long arm with integrated thumb mount and a boom holding valve with lift overload alarm.
TB257FR
Compact Excavator
The newest excavator in the FR series, the TB257FR mini excavator features a side-to-side (STS) offset boom coupled with the tight tail swing for unmatched visibility to the work equipment and enables it to rotate fully with very little overhang. With an operating weight of 12,930 lb, a bucket breakout force of 10,431 lb and multiple hydraulic auxiliary circuits makes the TB257FR an outstanding attachment platform and perfect for limited space job sites. Its low center of gravity and optimized counterweight placement creates an extremely stable platform with lifting capabilities similar to that of a conventional machine.

Function and Efficiency
- The variable displacement axial piston pump delivers smooth, harmonized control of the work equipment with no reduction in speed.
- The standard long arm with integrated thumb mount provides you with a wider working range, dig depth, and simplifies thumb installation.
- Having three auxiliary circuits allows you to run a wide range of hydraulically driven attachments and have a dedicated hydraulic coupler circuit.
- High flow capabilities of the primary auxiliary circuit will allow you to operate a broader range of hydraulically driven attachments, such as mowers, mulchers, and plate compactors.
- Load sensing, two speed travel down shifts from low torque/high speed mode to high torque/low speed travel automatically when turning, pushing dirt, or traveling up an incline.
- Large slew bearing provides greater longevity and stability over the life of the machine.
- Cushioned cylinders improve longevity by reducing shock and they reduce felt recoil to the operator for greater comfort.
- Available case drain line kit is recommended for use with an excavator mulcher.
Increased Protection
- All steel construction ensures body integrity through greater strength and rigidity and protects key components from damage.
- Heavy duty counterweight protects vital engine and hydraulic components from damage.
- Triple flange track rollers improve track life by providing greater support, and they feature multiple contact points that reduce the risk of de-tracking.
Operator Focused
- Deluxe high back adjustable suspension seat reduces operator fatigue while providing greater visibility to the work equipment and surrounding job site.
- Multifunction, LED monitor provides the operator with machine vitals, flow adjustments, and attachment presets.
- Electronic dial type throttle control allows the operator to quickly adjust engine speed, and the automatic engine idle feature will reduce engine speed to low idle automatically should the machine idle more than several seconds.
Peace of Mind
- The safe start system requires the safety lockout lever be in the raised position in order to start the excavator ensuring hydraulic functions are inactive at start-up.
- The boom holding valve and overload alarm are designed to keep the boom from dropping if there is a sudden loss in pressure, and the overload alarm will sound (when ON) if you exceed hydraulic capacity.
- Available drop-in 1/2″ poly carbonate glass or heavy duty 1/2″ poly carbonate window guard with steel frame, and steel front guard group provide the added protection you need when using hydraulically driven attachments.
