The IMER - TERRA CUT 500 SAW - 20” Blade - 1188863 is a high‑performance walk‑behind floor saw engineered for professional concrete and asphalt cutting, combining a 20‑inch diamond blade capacity with a powerful 13 HP Honda GX390 engine for deep, precise cuts on demanding job sites.

Overview of the IMER Terra Cut 500 20" Saw (1188863)

The IMER Terra Cut 500 is a compact, lightweight, and easy‑to‑handle floor saw specifically designed for cutting large concrete and asphalt surfaces efficiently and accurately. The 20” blade capacity allows operators to reach a maximum cutting depth of approximately 7.5 inches, making it ideal for roadwork, slab cutting, repair joints, trenching, and surface removal. Model package 1188863 is typically configured with a 13 HP Honda GX390 gasoline engine and a 20" diamond blade, giving contractors a versatile, job‑ready solution for heavy‑duty flat sawing.

This machine is built around a welded steel chassis that delivers high structural rigidity, helping maintain straight, true cuts even in tough conditions and on uneven surfaces. Despite its robust construction, the Terra Cut 500 is designed to be maneuverable and easy to control, so operators can work longer with less fatigue on large floor and pavement projects.

Engine, Power, and Drive System

At the heart of the IMER Terra Cut 500 1188863 package is the 13 HP Honda GX390 engine, a proven commercial‑grade powerplant known for reliability and fuel efficiency. The engine runs at a maximum speed of around 3,850 rpm, providing ample torque for driving a 20" diamond blade through cured concrete and dense asphalt materials. Starting is manual via recoil, which keeps the system simple and reduces maintenance compared to electric‑start packages.

The Terra Cut 500 uses a manual forward drive, meaning the operator walks behind the saw and controls its forward motion directly. This manual drive layout keeps the machine light, compact, and easier to transport while still delivering excellent control over cutting speed and direction. Combined with the engine’s power, it gives the operator a balanced feel between cutting performance and handling.

Blade Capacity, Cutting Depth, and Blade Options

One of the key advantages of the IMER Terra Cut 500 is its 20" blade capacity and generous cutting depth.

• Blade diameter: 20 inches (500 mm).

• Blade bore: 1 inch (25.4 mm).

• Maximum cutting depth: approximately 7.5 inches (190 mm).

• Maximum blade speed: about 2,900 rpm, with a peripheral speed up to 75 m/sec.

This depth range makes it suitable for full‑depth cuts on many slabs, partial‑depth repair cuts, and joint widening. IMER provides dedicated 20" premium diamond blades for both concrete and asphalt applications, allowing users to choose the ideal blade for each material. The IMER USA listing references reorder part numbers for blades such as:

• 20" premium diamond blade for concrete, part #1193921.

• 20" premium diamond blade for asphalt, part #1193925.

By matching the blade to the material, contractors can increase cutting speed, extend blade life, and improve overall finish quality.

Key Design Features and Patented Systems

The Terra Cut 500 stands out due to a series of ergonomic and safety‑oriented design features that support day‑to‑day professional use.

• Fast handwheel locking/unlocking system: A patented mechanism allows the operator to set the cutting depth using the handwheel and then quickly lock or unlock it, ensuring that the cutting depth stays consistent during operation.

• Double vibration damping system: The saw uses vibration dampers beneath the engine plate and under the handle support, significantly reducing vibration transmitted to the operator and improving comfort during long cuts.

• Automatic parking brake: Another patented feature links the parking brake to the blade lifting wheel, automatically engaging or releasing the brake based on the height of the machine. This improves stability and safety during setup and transport.

• Polyethylene water tank with quick joint: A large‑capacity (around 30 L) removable water tank made from durable polyethylene is fixed with a quick‑joint system for easy positioning and removal. This tank supplies water to the blade to control dust and cool the cutting zone.

• Welded steel chassis: The rigid welded steel frame with reinforcing ribs maintains structural stiffness, ensuring precise cutting geometry under load and across rough job sites.

Collectively, these features make the Terra Cut 500 not only powerful but also comfortable and safe to operate, even for extended shifts.

Dimensions, Weight, and Handling

The IMER Terra Cut 500 is designed to balance stability with portability.

• Weight: approximately 287 lbs (around 130 kg depending on engine configuration).

• Dimensions (width/length/height): about 24 in x 54 in x 48.5 in with the blade mounted and guide raised.

• Noise level at operator’s position: approximately 91 dB(A).

These specifications make the unit robust enough to stay planted and stable while cutting, yet compact enough to load into standard work vehicles and move around job sites. The adjustable, vibration‑damped handlebar further improves handling by letting different operators choose a comfortable working height and angle.

Applications: Where the Terra Cut 500 Excels

The IMER Terra Cut 500 20" floor saw is built for heavy‑duty professional applications in concrete and asphalt cutting.

Typical uses include:

• Cutting expansion joints and control joints in concrete slabs.

• Sawing asphalt pavement for road and highway repair work.

• Trenching for utilities, pipes, and conduit in concrete or asphalt surfaces.

• Surface removal and partial‑depth repair cuts in parking lots, driveways, and warehouse floors.

• Creating clean, straight edges around patches or demolition sections.

Because of its combination of power, depth, and maneuverability, the Terra Cut 500 is ideal for contractors, municipalities, and concrete cutting specialists who need a reliable, mid‑sized walk‑behind saw for frequent site work.

Comparison to Other IMER Floor Saws

Within the IMER floor saw lineup, the Terra Cut 500 sits as a heavy‑duty, 20"‑blade class machine oriented to larger surfaces and deeper cuts. Smaller IMER floor saws may use smaller blades and offer reduced cutting depth, making them better suited for lighter or thinner slabs, while the Terra Cut 500 offers more capacity and a more substantial chassis.

Other IMER saw families, such as the Masonry saw series (Masonry 500, Masonry 750), are designed primarily for bricks, blocks, stone, and precast units rather than floor cutting. By contrast, the Terra Cut 500 is optimized as a walk‑behind floor saw for horizontal surfaces, and its blade, water delivery, and chassis reflect that specialization.

Benefits of Choosing the IMER Terra Cut 500 20" (1188863)

Choosing the IMER Terra Cut 500 with 20” blade and Honda GX390 engine under part number 1188863 offers several practical advantages to professional users.

• High productivity: The powerful 13 HP engine and 20" blade allow deep, fast cuts in dense materials, increasing daily output.

• Consistent cutting depth: The patented fast locking handwheel system keeps the cutting depth set throughout the cut, helping avoid uneven cuts and rework.

• Operator comfort: Dual vibration damping on both the engine plate and handle reduces fatigue and improves control during long passes.

• Safety and control: The automatic parking brake linked to blade height helps secure the machine during setup, parking, and transport.

• Effective dust and cooling management: The large polyethylene water tank with quick joint connection provides continuous blade cooling and helps control silica dust on site.

• Durability: The welded steel chassis and high‑quality components are designed to withstand tough construction environments and frequent transportation.

For contractors who frequently cut both concrete and asphalt, pairing the saw with IMER’s premium 20" blades for each material rounds out a complete and efficient cutting system.
