The Extendo 1258X takes rugged Pettibone performance to another level. Offering 12,000 pounds of load capacity with its 4-section boom, the 1258X is the ultimate machine for tough jobs.

Drivetrain and axles have been optimized to provide greater tractive effort with minimal tradeoff on top end speed.

• Dana 223 Series high steer axles provide excellent tractive effort.
• Tight steer angle capability provides efficient turning radius.
• Dana VDT12000 Powershift transmission offers 3 speeds, forward and reverse.
• Full time 4-wheel-drive with limited-slip front axle differential.

The 4-section boom features formed boom plates that offer greater strength with less weight.

• Boom deflection minimized for better control and accuracy placing loads.
• Boom overlap nearly doubled to provide smoother operation and reduce contact forces on wear pads.
• Fastener-less wear pads simplify service.
• Bottom-mounted external extend cylinder significantly reduces load on wear pads; cylinder location also provides better service access to internal boom components.
• Compression tilt design allows for a smaller bore cylinder with same tilt force.
• Heavy-duty extension chains help ensure stable boom functions and longevity.

Axle-mounted outriggers come standard on the 1258X.

• Machine chassis will sway independent of the outrigger system.
• Outriggers positioned to provide clear visibility out to the fork tips.

The Extendo's hydraulic circuit delivers exceptional controllability, efficiency and cycle speeds.

• Cylinder cushioning dampens the end of strokes – both extending and retracting – to prevent hard, jarring stops and avoid both wear-and-tear and potential load spills.
• Single lift cylinder provides operator with clear sight lines.
• Twin lines for tilt and auxiliary plumbing.

The operator cab includes ergonomic seat, pedal, joystick and steering wheel positions. Available as an open canopy or enclosed cab, it features an all-steel interior with water-resistant components for easy washdown.

• New analog/LCD gauge cluster.
• Enhanced climate control system.
• Split door design allows upper half to lock in the open position.
• Flat, bolt-in glass can easily be removed or replaced.
• Openable rear window improves air flow while keeping cab dry.
• Lockable storage area under seat for manual, gloves and tools.

• Split-system electrical panels allow for easier service of individual circuits.
• Heavy-duty bright LED lighting.
• Weather-sealed connections.
• USB accessory plug in cab.
• 12-volt accessory plug in engine bay.

• Easy access to all filters and fluid level indicators.
• Lockable fuel-fill in clean, accessible location.
• Inside of boom easily accessible for service.
• Non-tensioned boom hoses offer long service life.
