Floor Saw for Sale: Complete Guide to Buying a Concrete Floor Saw

Searching for a floor saw for sale usually means you need a professional machine capable of cutting concrete, asphalt, reinforced concrete, pavement, road surfaces, or slabs more efficiently than a handheld saw. Also called a concrete floor saw, flat saw, road saw, slab saw, or walk-behind concrete saw, these machines are designed for straight, controlled cuts at depths that can range from a few inches to well over a foot on large commercial models.

Floor saws are available in push and self-propelled configurations with gasoline, diesel, and electric power. Smaller machines are ideal for repairs, sidewalks, driveways, and utility work, while high-horsepower self-propelled saws are built for highways, airports, industrial slabs, and major concrete-cutting projects.

The best floor saw for sale is not necessarily the machine with the most horsepower. Buyers should compare required cutting depth, blade diameter, material, engine type, drive system, water delivery, transportation requirements, maintenance, and expected daily production.

What Is a Floor Saw?

A floor saw is a walk-behind cutting machine designed to cut horizontal concrete or asphalt surfaces using a large diamond blade.

Unlike a handheld power cutter, the machine's frame supports the engine, blade shaft, guard, wheels, and other components. This allows the operator to guide the saw along a predetermined cutting line.

Floor saws are commonly used for:

• Concrete slab cutting

• Asphalt cutting

• Road repair

• Expansion joints

• Utility trenches

• Concrete removal

• Parking lots

• Driveways

• Airport pavement

• Industrial floors

• Bridge decks

• Highway construction

Husqvarna's current flat-saw lineup, for example, ranges from compact 14-inch push saws to diesel machines accepting blades as large as 60 inches.

Floor Saw vs. Walk-Behind Concrete Saw

The terms floor saw and walk-behind concrete saw usually refer to the same general type of equipment.

Other common names include:

• Flat saw

• Slab saw

• Road saw

• Concrete saw

• Asphalt saw

• Walk-behind saw

“Floor saw” and “flat saw” emphasize horizontal cutting, while “road saw” is commonly used when the machine is intended primarily for pavement and asphalt.

Regardless of terminology, the important specifications are blade size, cutting depth, horsepower, propulsion, and material compatibility.

Concrete Floor Saw for Sale

A concrete floor saw for sale should be selected according to the concrete being cut.

Small repair work may require only a compact push saw.

Heavy reinforced concrete can require considerably more power.

Professional concrete saws typically use diamond blades engineered around variables such as:

• Concrete hardness

• Aggregate

• Reinforcement

• Blade horsepower

• Cutting depth

• Wet or dry application

The saw and blade work as a system. Installing an inexpensive or poorly matched blade on a powerful floor saw can reduce productivity and increase operating costs.

Walk-Behind Concrete Saw for Sale

Walk-behind saws are popular because they provide much better depth control and straight-line accuracy than attempting long slab cuts with a handheld power cutter.

There are two major configurations.

Push Floor Saw

The operator physically pushes the machine forward.

Push saws are generally:

• Smaller

• Lighter

• Easier to transport

• Less expensive

• Well suited to shorter cuts

Husqvarna's current push range includes machines such as the FS 309, FS 400 LV, FS 413, and electric FS 600 E. Maximum cutting depths range from approximately 4.9 inches on the FS 309 to 7.8 inches on the FS 600 E.

Self-Propelled Floor Saw

A self-propelled saw uses a drive system to move the machine.

This reduces the amount of physical force required from the operator and improves productivity on long cuts.

Self-propelled saws are commonly preferred for:

• Highway work

• Long slab cuts

• Large commercial projects

• Deep cutting

• High-production concrete cutting

Small Floor Saw for Sale

A compact floor saw can be the best choice for contractors performing repairs and smaller concrete projects.

One current example is the Husqvarna FS 400 LV.

It uses an 11.7-hp gasoline engine, accepts a maximum 20-inch blade, and provides up to 7.5 inches of cutting depth. Husqvarna currently lists the machine at $3,349.

The FS 400 LV also includes an integrated water tank, adjustable handles, depth indicator, and folding handle design.

This class of saw works well for:

• Driveways

• Sidewalks

• Small road repairs

• Parking lots

• Concrete slabs

• Asphalt repair

A smaller floor saw is also much easier to load into a truck or trailer than a large diesel machine.

Husqvarna also offers the FS 7000 DL, which can accept 48- or 60-inch blades and cut as deep as 25 inches.

This range demonstrates why identifying the application before buying is so important.

Gas Floor Saw for Sale

Gasoline-powered floor saws are extremely common.

They provide good portability because they do not require an electrical connection.

Gas floor saws work well for:

• Outdoor construction

• Road repair

• Driveways

• Parking lots

• Utility work

• Concrete slabs

• Asphalt

Smaller gasoline machines are often equipped with commercial Honda engines, while larger machines can use higher-output gasoline powerplants.

For example, the Husqvarna FS 3500 G EFI delivers 37 hp and is self-propelled. It accepts blades up to 30 inches and cuts up to 12.25 inches deep.

Diesel Floor Saw for Sale

Diesel floor saws are designed primarily for heavy professional production.

A good example is the Husqvarna FS 5000 D.

The current model uses a 47.6-hp Yanmar diesel engine and accepts 26-, 30-, or 36-inch blade configurations, providing cutting depths of approximately 10.5, 12.5, or 15 inches.

This machine is designed for high-performance asphalt and concrete cutting.

Large diesel saws are typically appropriate for:

• Highway construction

• Airport work

• Bridge decks

• Heavy commercial concrete

• Infrastructure projects

• High-production cutting

The current 36-inch FS 5000 D carries a manufacturer list price of $49,999, illustrating how far professional floor saw pricing can extend beyond compact push saws.

Electric Floor Saw for Sale

Electric floor saws are useful where combustion-engine exhaust is undesirable or electrical power is readily available.

Husqvarna's current lineup includes machines such as the FS 600 E and larger FS 3500 E.

The FS 3500 E is a self-propelled corded saw rated at 30 hp. Depending on configuration, it accepts 26- or 30-inch blades and reaches maximum cutting depths of approximately 10.5 or 12 inches.

Electric saws can be particularly valuable for indoor renovation, industrial facilities, warehouses, and other environments where gasoline or diesel exhaust presents a problem.

Electrical requirements must be verified before purchasing.

Floor Saw for Cutting Asphalt

Asphalt requires a blade designed for abrasive material.

Because asphalt is generally more abrasive than cured concrete, using the wrong blade can cause rapid segment wear.

Floor saws are commonly used for:

• Pothole repair

• Utility trenches

• Road patching

• Driveway repair

• Parking lot work

• Pavement replacement

For frequent asphalt cutting, look for a machine with good straight-line tracking, sufficient horsepower, water capability, and easy depth adjustment.

Floor Saw for Reinforced Concrete

Reinforced concrete can be significantly more demanding than ordinary concrete because the blade may encounter steel reinforcement.

For this application, choose:

• A sufficiently powerful saw

• A reinforced-concrete diamond blade

• Appropriate blade diameter

• Adequate cutting depth

• Reliable water delivery

Large commercial projects may justify moving from a small push saw to a self-propelled machine.

More horsepower helps maintain production as cutting resistance increases.

What Size Floor Saw Do I Need?

Start with required cutting depth.

A compact 14-inch saw may provide roughly 5 inches of depth, while a 20-inch saw can reach around 7 to 8 inches depending on machine design.

Larger equipment goes considerably deeper.

Husqvarna's current lineup demonstrates the progression clearly: the 14-inch FS 309 reaches 4.9 inches, the 20-inch FS 400 LV reaches 7.5 inches, the 24-inch FS 524 reaches 9.7 inches, and certain 36-inch FS 5000 D configurations reach 15 inches.

Do not buy a much larger machine than the job requires.

Larger saws increase purchase price, transportation requirements, blade cost, fuel consumption, and maintenance.

14-Inch Floor Saw

A 14-inch floor saw is useful for relatively shallow cuts.

Typical applications include:

• Sidewalk repairs

• Driveways

• Asphalt patching

• Small trenches

• Residential slabs

Compact machines are easier to transport and maneuver.

They are a practical entry point for contractors who do not regularly need deep cuts.

20-Inch Floor Saw

A 20-inch floor saw is one of the most versatile sizes for general concrete work.

Current Husqvarna 20-inch machines provide roughly 7 to 7.8 inches of cutting depth depending on model.

This makes the 20-inch class suitable for many:

• Commercial slabs

• Road repairs

• Parking lots

• Utility cuts

• Driveways

• Concrete removal projects

It offers substantially more depth than a handheld 14-inch power cutter without requiring the size and cost of a large diesel floor saw.

24-Inch Floor Saw

A 24-inch floor saw moves into deeper professional cutting.

The Husqvarna FS 524, for example, combines a 20.8-hp gasoline engine with a maximum 24-inch blade and approximately 9.7 inches of cutting depth.

This class works well when contractors need additional depth but still want a relatively manageable machine.

30-Inch and 36-Inch Floor Saws

Large blades are generally paired with high-output self-propelled saws.

The FS 3500 G EFI supports blades up to 30 inches and reaches 12.25 inches deep.

The FS 5000 D goes further, accepting blades up to 36 inches and reaching approximately 15 inches.

These machines are intended for professional concrete-cutting companies rather than occasional residential projects.

Floor Saw Price

Floor saw prices vary enormously.

A compact professional push saw may cost several thousand dollars. Husqvarna currently lists the FS 400 LV at $3,349.

High-production equipment can reach tens of thousands of dollars. Current Husqvarna starting prices include approximately $48,999 for the FS 5000 D, $62,099 for the FS 7000 D Tier 4, and $82,099 for the FS 7000 DL Tier 4.

Price is influenced by:

• Horsepower

• Blade capacity

• Cutting depth

• Drive system

• Engine

• Frame design

• Controls

• Tracking technology

• Transmission

• Accessories

For professional contractors, productivity and operating cost can matter more than purchase price alone.

New vs. Used Floor Saw for Sale

Used floor saws can provide excellent value, but they should be inspected carefully.

Check:

• Engine condition

• Blade shaft

• Bearings

• Belts

• Pulleys

• Drive system

• Wheels

• Tracking

• Water system

• Blade guard

• Depth adjustment

• Hour meter

• Maintenance records

A worn blade shaft or neglected drive system can turn an inexpensive used saw into an expensive repair project.

For large diesel machines, service history becomes particularly important.

Push vs. Self-Propelled Floor Saw

Choose a push saw when portability, lower cost, and shorter cuts are priorities.

Choose a self-propelled saw when productivity and operator comfort matter more.

Self-propelled machines become increasingly valuable when performing long cuts because the drive system controls forward movement instead of requiring the operator to continuously push a heavy machine.

Husqvarna specifically positions its large self-propelled flat saws for demanding concrete and asphalt cutting.

Floor Saw Blades

A floor saw is only as effective as the blade installed on it.

Diamond floor-saw blades can be optimized for:

• Green concrete

• Cured concrete

• Reinforced concrete

• Asphalt

• Abrasive materials

Blade diameter, arbor, horsepower range, segment bond, and maximum RPM must match the machine.

Husqvarna, for example, lists dedicated floor-saw blades for its machines, including concrete-oriented VARI-CUT and ELITE-CUT options.

Using the correct blade can increase cutting speed while reducing unnecessary wear.

Wet Cutting with a Floor Saw

Water is commonly delivered directly to the blade during concrete and asphalt cutting.

Water helps:

• Control dust

• Cool the blade

• Flush cutting debris

• Improve operating conditions

Some compact saws include integrated water tanks. The FS 400 LV, for example, incorporates a large water tank and a quick connection to deliver water to the blade guard.

Larger machines may use external water supplies or optional pump systems.

What to Look for When Buying a Floor Saw

Before purchasing, compare the machine against your most common jobs.

The key questions are:

• What material will you cut?

• How deep must you cut?

• How many feet will you cut per day?

• Do you need push or self-propelled operation?

• Is gasoline, diesel, or electric power best?

• What blade diameter do you need?

• How will the machine be transported?

• Are replacement parts readily available?

• Is dealer service available?

• What diamond blades fit the saw?

Buying based only on horsepower can lead to unnecessary cost.

The machine should fit your workload.
