Bobcat launches next-gen augers and trenchers

Bobcat has expanded its attachment lineup with the launch of new auger attachments and trencher attachments designed for compact equipment. The new generation includes five auger drive models and five trencher models compatible with a wide range of Bobcat machines.

For contractors using skid steer loaders, compact track loaders, mini excavators, compact wheel loaders, small articulated loaders, and telehandlers, this release focuses on three things: hydraulic performance, deeper digging capability, and better operator control.

This article breaks down:

• The new Bobcat auger models and specifications
• The new Bobcat trencher models and digging depths

Bobcat new auger attachment specs

Bobcat introduced five new auger drive models:

• 11H
• 28H
• 28LH
• 33H
• 55LH

These drives are designed to work with a broad range of Bobcat machines, including:

• Bobcat skid steer loaders
• Compact track loaders
• Mini excavators
• Small articulated loaders
• Compact wheel loaders
• Telehandlers

Hydraulic flow range

The new auger drives operate across hydraulic flows from 30 to 200 l/min, depending on the model. This wide range allows compatibility with:

• Standard-flow compact machines
• High-flow skid steer loaders
• Larger telehandlers

High-flow hydraulics are critical because torque output directly depends on oil flow and pressure. More flow means:

• Faster penetration
• More consistent rotation under load
• Reduced stalling in dense soil

For contractors working in clay, compacted ground, or mixed soil conditions, this is a major productivity factor.

What makes these Bobcat augers different?

The new auger range includes several technical improvements.

1. Integrated motor design

The motor is integrated into the drive unit, which:

• Reduces overall size
• Lowers weight
• Minimizes leak points
• Reduces the number of components

Fewer components typically mean improved durability and easier maintenance.

2. Extra digging depth

Bobcat states the new drives allow up to 30 cm additional digging depth because the entire drive unit follows the auger bit into the hole.

This matters when drilling:

• Fence post holes
• Foundation piers
• Utility pole bases
• Sign installation holes

Deeper reach without repositioning increases job speed.

3. LED alignment system (LH models)

The 28LH and 55LH auger drives feature an integrated LED alignment system.

How it works:

• Full green ring = auger perfectly vertical
• Green and red mix = misalignment
• Green on one side = direction to correct

This helps operators maintain plumb-line accuracy without external tools.

For contractors installing structural posts or foundation supports, vertical accuracy reduces rework.

Bobcat new trencher attachments specs

Bobcat introduced five new trencher models:

• LT90
• LT90 HD
• LT120
• LT120 HD
• LT150 HD

These trenchers are now available for Bobcat mini excavators, in addition to loaders.

Digging depth range

The new trenchers cover digging depths from: 450 mm to 1500 mm

This allows use in:

• Irrigation installation
• Electrical conduit trenching
• Fiber optic cable placement
• Drainage systems

What features improve trenching performance?

The new trenchers include several heavy-duty features.

1. Heavy-duty crumbing system

A spring-loaded crumber:

• Maintains constant contact with trench floor
• Removes spoil effectively
• Leaves a clean trench

It can also be folded away when not required. This reduces the need for secondary cleanup passes.

2. Planetary drive system

The trenchers use a powerful planetary drive to deliver:

• Higher torque
• Better load distribution
• Increased durability

Planetary drives are preferred in heavy-duty attachments because they:

• Distribute stress across gears
• Extend service life
• Reduce premature wear

3. Adjustable skid foot

The adjustable skid foot allows up to four preset digging depths.

This means operators can:

• Change depth quickly
• Use one attachment for multiple trench requirements
• Avoid manual recalibration each time

4. Side-shift capability

The trencher frame can shift sideways.

This allows digging directly next to:

• Foundations
• Kerbs
• Walls
• Permanent structures

This is especially useful in tight urban jobsites.

Do attachments increase the resale value of skid steer?

Yes, but only if:

• Hydraulic system is healthy
• Attachment is well-maintained
• Mounting system is compatible

A loader sold with high-demand attachments like augers and trenchers may attract stronger resale interest.

Conclusion

Bobcat’s next-generation augers and trenchers focus on hydraulic performance, deeper digging capability, and operator precision.

Key improvements include:

• Hydraulic flow range from 30–200 l/min
• Up to 30 cm additional digging depth (augers)
• LED alignment system for accurate drilling
• 450–1500 mm trenching depth range
• Heavy-duty crumbing system
• Planetary drive torque system
• Side-shift trenching capability

For contractors using skid steer loaders, compact track loaders, mini excavators, and telehandlers, these attachments increase machine versatility and productivity.

As compact machinery continues to dominate urban and utility projects, attachments like augers and trenchers remain critical productivity tools.

FAQ

1) What hydraulic flow is required for Bobcat augers?

Flow requirements range from 30 to 200 l/min depending on the model and machine.

2) What is the maximum trench depth of the new Bobcat trenchers?

The range covers 450 mm to 1500 mm depending on the model.

3) Are the new Bobcat trenchers compatible with mini excavators?

Yes, the new generation trenchers are available for Bobcat mini excavators.

4) What does the LED alignment system do?

It visually indicates vertical alignment using green and red LED signals to improve drilling accuracy.

5) Do high-flow hydraulics improve auger performance?

Yes. Higher hydraulic flow increases torque and reduces stalling in hard ground conditions.
