Our Marsh Buggy Fleet & Other Equipment

Getting people, tools, and material into a marsh jobsite takes more than a pickup truck and optimism. Our fleet is built for soft ground, floating access, tight right-of-way corridors, and the kind of terrain that turns “quick mobilization” into a comedy show for anyone who shows up unprepared.

Below is a detailed look at the equipment we keep ready, what each unit is good at, and how we pair machines and attachments to match real field conditions.

Our marsh buggy fleet and support equipment

Our marsh excavation and airboat transportation fleet includes: 9 airboats, 1 Bobcat 442 excavator, 5 Wilson marsh excavators (3 Bobcat 337 units and 2 Bobcat E63 units), Gator Foot amphibious vehicles, 2 commercial hydroseeders, plus a full spread of specialty attachments (tillers, saw blades, bush hogs, and Denis Cimaf grinder/chippers).

If you want to see the machines working (instead of sitting still for nice photos), our YouTube channel is the place to look.

9 Airboats

Airboats are our “no roads needed” move. When a jobsite is across open water, behind a wall of vegetation, or in an area where conventional access is a non-starter, airboats keep the schedule from getting eaten alive.

What airboats do well

  • Crew transport to remote sites for survey, inspection, construction support, maintenance, and repair work.

  • Light material hauling: gear, small tools, consumables, parts, and supplies that need to arrive dry and on time.

  • Shallow water travel where prop boats can’t run and trucks can’t float (for obvious reasons).

Typical use cases

  • Pipeline and utility right-of-way access

  • Survey line access and staking support

  • Environmental and spill response support (moving crews and equipment fast)

  • Pre-work reconnaissance and “let’s go look at it” trips before the big iron shows up

Airboat work looks simple until the wind shifts, the water drops, and the route turns into a maze of grass and mud. We run routes that are picked for safety, speed, and repeatability, because “we’ll just wing it” is a great plan right up until it isn’t.

5 Wilson marsh excavators (3 Bobcat 337 + 2 Bobcat E63)

Marsh excavators are the backbone of wetland production work. We run Wilson marsh excavators powered by Bobcat excavator units (337 and E63). These are the machines that let us dig, trench, clear, shape, reclaim, and maintain in soft ground where standard excavators either sink, stall, or become an expensive lawn ornament.

Why marsh excavators matter in wetlands

Wetlands are a mixed bag: peat, muck, floating mats, submerged stumps, root balls, and soft soils that don’t forgive heavy ground pressure. Marsh excavators are built to operate with reduced ground pressure and better flotation so we can move, work, and reposition without tearing up everything in sight.

Common tasks for marsh excavators

  • Marsh excavation for restoration and maintenance scopes

  • Marsh trenching for pipe, fiber, and utility installation

  • Pipeline clearing and right-of-way maintenance (cutback, access, and cleanup)

  • Tree grubbing and vegetation control where permitted and required

  • Levee and berm shaping for flood control and protection projects

  • Disaster cleanup support, especially when debris is scattered across soft ground and shallow water

How we set them up for your scope

A marsh excavator is only as useful as the tool on the stick. We keep multiple attachments staged and ready so we can match the job to the right setup instead of trying to “make it work” with the wrong iron.

1 Bobcat 442 excavator (dry land support)

Not every project is 100% marsh. Access roads, staging pads, upland tie-ins, spoil placement, and transition zones often need conventional digging and grading. That’s where our Bobcat 442 excavator fits.

Where the 442 shines

  • Upland prep work and cleanup

  • Tie-in areas where you need solid footing and tighter machine control

  • Supporting marsh crews with onshore tasks so the wetland units stay productive

  • Handling work that is “marsh-adjacent,” not truly marsh

The 442 also plays well when we need a dry-land unit to support grinding and clearing work on firm ground.

Gator Foot amphibious vehicles (amphibious personnel carriers)

When the scope calls for moving people and gear through swamps, marshes, flooded ground, snow, sand, or other “pick your problem” terrain, Gator Foot vehicles are a strong option. They’re designed for amphibious operation and can handle a wide range of site conditions.

What we use them for

  • Wetland reclamation and restoration: These vehicles are built for tough reclamation and restoration projects in utility, pipeline, and construction work.
  • Disaster cleanup: After hurricanes or river flooding, amphibious carriers help reach flooded areas and move through debris fields to support cleanup.
  • Material handling and personnel transportation: With a rear cargo bed, they can haul materials and move crews like pipeline maintenance teams and survey crews into hard-to-reach areas.

Capability that matters in the field

Our Gator Foot vehicles offer over 8,000 pounds of pulling capacity, which is a big deal when you’re moving equipment, freeing stuck gear, or handling loads that don’t want to cooperate.

If the job needs a carrier that can crawl through soft ground and still keep moving when conditions change, these are worth a serious look.

2 commercial hydroseeders (erosion control support)

Once earthwork is done, the job usually isn’t “done.” Slopes, disturbed soils, and new grades often need stabilization to control erosion and protect the finished work. We keep 2 commercial hydroseeders available.

Hydroseeding is especially helpful when a project includes:

  • Levee construction or repair

  • Land reclamation and restoration work

  • Erosion control requirements tied to permits or environmental commitments

  • Fast coverage needs on disturbed soil

Attachments that turn “a machine” into “the right machine”

Attachments are where production happens. A marsh excavator with the wrong head is like bringing a butter knife to a pipe rack. It technically exists, but it’s not helping anybody.

Here’s what we keep in the lineup.

5 tiller attachments for marsh excavators

Tiller heads are used for soil conditioning and surface prep. They help when you need to:

  • Break up root mats and soft material for grading and restoration

  • Prep areas for stabilization work

  • Blend disturbed soil to reduce uneven settlement

  • Improve access paths by conditioning the surface

In wet ground, the goal is controlled disturbance; enough to accomplish the work, not so much that you create a bigger problem than you started with.

4 saw blade attachments for marsh excavators

Saw blades are for controlled cutting where standard buckets and thumbs aren’t the tool. These are useful for:

  • Cutting woody vegetation and problem growth along corridors

  • Clearing access lanes in tight spaces

  • Supporting pipeline and utility right-of-way maintenance

  • Controlled removal where you need cleaner cuts and better reach

If you’ve ever watched someone try to “muscle through” with the wrong attachment, you know why saw blades earn their keep.

2 bush hogs for marsh excavators

Bush hog attachments handle heavier vegetation management and cutback work. When the corridor is overgrown, this is how we get back to a workable ROW without turning the schedule into a slow-motion slide show.

Typical tasks include:

  • ROW maintenance and vegetation control

  • Clearing for survey access and staking

  • Prepping areas for trenching or excavation

3 Denis Cimaf grinder/chippers for marsh excavators

Grinding and mulching in wetlands is its own category of headache. Denis Cimaf grinder/chippers help us process vegetation and wood material efficiently using the excavator platform.

This is especially useful for:

  • Clearing with less hauling of bulky vegetative debris

  • Reducing material for easier handling and disposal

  • Supporting land reclamation scopes where mulch is part of the plan

  • Site prep where you want material managed, not just moved around

How we match fleet + scope in the real world

A fleet list is nice, but the part that matters is: what shows up, in what order, and why.

1) Access first

If crews and materials can’t reach the work zone, everything else is paperwork. Airboats and amphibious carriers typically solve early access problems so staking, layout, and pre-work can happen fast.

2) Production iron next

Marsh excavators come in once access and staging are figured out. We’ll choose the machine and attachment combo based on:

  • Soil type and water depth

  • Vegetation density and root mat thickness

  • Required trench depth/width and spoil placement needs

  • Restoration requirements and environmental constraints

3) Finish and stabilize

Once excavation, trenching, or clearing is complete, we support finish work and stabilization. That can include grading, cleanup, and hydroseeding/erosion control where the project requires it.

Industries and projects this fleet supports

Our equipment lineup is built to support work where conventional equipment struggles or fails. It fits well for:

  • Pipeline and oilfield services (ROW access, clearing, trenching, maintenance support)

  • Utilities and communications (including wetland access and installation support)

  • Surveying and engineering support (transport and access to remote lines)

  • Government and public works (restoration, levees, cleanup, and maintenance scopes)

  • Disaster response and recovery (flooded access, debris fields, rapid mobilization support)

We’re based in Louisiana and provide service beyond the state when the project calls for it.
