ANBO Grapple Guide: Understanding the GR75, GR120 & GR140

The ANBO GR75, GR120, and GR140 grapple rakes share a very similar overall design—and that is intentional.

Each model is built around the same proven GR-series concept. As machine horsepower, weight, traction, and attachment forces increase, the grapple is reinforced with thicker USA-sourced AR400F steel tines and additional cross bracing.

The goal is not to make every grapple as heavy as possible. It is to match the attachment to the machine so it can withstand demanding use without adding unnecessary weight that reduces lifting capacity.

The Same Design, Built for Different Machine Classes

The GR75, GR120, and GR140 use the same general grapple-rake profile and are designed for many of the same jobs, including:

• Brush and storm cleanup

• Moving logs and limbs

• Forestry work

• Land clearing

• Root and debris removal

• Rock and material handling

  
  

The main differences are tine thickness and structural reinforcement. As the recommended machine horsepower increases, ANBO adds thicker tines and more cross bracing to withstand greater pushing, pulling, twisting, and clamping forces. Each model is named for its recommended horsepower class. For example, the GR75 is designed for tractors and wheeled skid steers up to 75 horsepower.

GR75: Built for Machines Up to 75 Horsepower

The GR75 is generally recommended for tractors and wheeled skid steers up to 75 horsepower.

It is built with:

• 5/8-inch outer tines

• 1/2-inch inner tines

• USA-sourced AR400F steel

  
  

The thicker outer tines provide additional strength along the sides, while the 1/2-inch inner tines maintain durability without adding unnecessary weight.

For most wheeled machines up to 75 horsepower, the GR75 offers a strong balance of durability, attachment weight, and usable loader capacity. For compact track loaders in the 75-horspower range we recommend the GR120 due to the extra traction the tracks give which adds stress on the grapple rake.

GR120: More Reinforcement for Larger Machines

The GR120 follows the same general design as the GR75 but is reinforced for machines up to approximately 120 horsepower.

• 3/4-inch outer tines

• 5/8-inch inner tines

• USA-sourced AR400F steel

• Additional cross bracing

  
  

The thicker tines and added reinforcement allow the GR120 to withstand the increased torque and structural loads produced by larger tractors, skid steers, and compact track loaders. For compact track loaders from 70 to 85-horsepower we recommend the GR120. For compact track loaders in the 85 to 112-horsepower range we recommend the GR140. 

GR140: Built for High-Horsepower Applications

The GR140 is designed for machines up to approximately 140 horsepower.

It is built with:

• 3/4-inch AR400F steel tines throughout

• Additional cross bracing

• Reinforced structural components

  
  

The GR140 is recommended for larger compact track loaders from 85 horsepower 112-horsepower, skid steers, and higher-horsepower tractors performing demanding land clearing, forestry work, and material handling.

Tine Construction Comparison

Model	Outer Tines	Inner Tines	Material
GR75	5/8 inch	1/2 inch	USA-sourced AR400F steel
GR120	3/4 inch	5/8 inch	USA-sourced AR400F steel
GR140	3/4 inch	3/4 inch	USA-sourced AR400F steel

The progression is simple: as the machine class increases, the tine thickness and structural reinforcement increase with it.

Why Horsepower Is Only the Starting Point

Horsepower is important, but it should not be the only factor used to select a grapple.

Two machines with similar horsepower can place very different forces on an attachment. ANBO also considers:

• Machine weight

• Lift capacity

• Tracks versus wheels (traction force)

• Intended use (ripping roots and digging rocks vs just moving material)

  
  

A wheeled skid steer and a compact track loader may have similar horsepower, but they should not automatically use the same grapple.

Why Compact Track Loaders Often Need a Stronger Grapple

ANBO will often recommend upsizing a grapple for a compact track loader.

For example, a 74-horsepower wheeled skid steer or tractor may be properly matched with a GR75. A compact track loader with similar horsepower may require a GR120.

The main difference is traction.

A tractor or wheeled skid steer will often spin its tires when it encounters significant resistance. This limits the amount of force it can continue transferring into the attachment.

A compact track loader has more ground contact and traction. Its tracks allow it to continue pushing, pulling, and twisting where a wheeled machine may spin out.

That additional traction can place much greater torque and structural stress on the grapple. For this reason, compact track loaders should not be matched to a grapple based on horsepower alone.

Not Every “Heavy-Duty Skid Steer Grapple” Is the Same

Many grapples are marketed broadly as heavy-duty skid steer grapples. However, wheeled skid steers and compact track loaders vary greatly in horsepower, machine weight, lift capacity, traction, and the amount of force they can transfer into an attachment.

A grapple built for a smaller wheeled skid steer may not be sufficiently reinforced for a heavier compact track loader, even if both machines use the same universal skid steer mount.

The term “heavy duty” does not provide enough information by itself. Especially since, in this industry, there is no real guideline for what is actually required to call an attachment "heavy duty". There are grapples out there being marketed as "heavy duty" while using grade 36 steel. You always want to research and not just take a companies word for it. All of our grapples are made from AR400F steel, which is up to 5x stonger than Grade 36 steel.

A grapple may mount to a machine but still be underbuilt for the forces that machine can generate. It may also be unnecessarily heavy for a smaller machine, reducing the amount of material it can carry.

That is why ANBO fits each customer based on the specifications of their machine. This helps ensure the grapple is truly heavy duty and built to perform. 

Standard GR Series vs. High Capacity Models

The GR75, GR120, and GR140 are also available in High Capacity models:

• GR75HC

• GR120HC

• GR140HC

  
  

The High Capacity designation refers to the grapple’s geometry and carrying space. It does not increase its horsepower rating or structural class.

A GR75HC remains in the GR75 strength class, while the GR120HC and GR140HC retain the strength levels of their corresponding standard models. The standard GR series is shown on the left, and the High Capacity series is shown on the right in the image below.

Benefits of the High Capacity Design

More Interior Carrying Space

High Capacity grapples provide more interior room when the grapple is closed, allowing them to carry larger loads of bulky or irregular material.

This design is especially useful for:

• Brush

• Limbs

• Logging debris

• Storm debris

• Loose vegetation

  
  

Longer, More Visible Bottom Tines

The High Capacity models also use longer bottom tines, which can make the tine tips easier to see from the cab.

This can help when:

• Sliding underneath logs

• Approaching brush piles

• Picking up loose material

• Positioning the grapple close to the ground

• Loading and unloading material

  
  

Standard GR Geometry for Root and Ground Work

The standard GR75, GR120, and GR140 use a more rounded bottom-tine geometry.

This shape is generally better for digging, raking, and working around roots because it allows the grapple to roll into and through the ground more naturally.

The High Capacity design uses a longer, flatter tine profile. This improves carrying capacity and tine-tip visibility, but the flatter bottom-tine geometry can make ground penetration less predictable. Rather than naturally rolling into the soil like the more rounded GR-series tines, the flatter HC tines tend to bite or dive into the ground more aggressively. The rounded GR profile gives the operator better control when raking, digging roots, or working just below the surface because the tine angle transitions into the ground more gradually.

How ANBO Fits a Grapple to Your Machine

ANBO grapples are built to order based on the machine and application.

Rather than placing every tractor, skid steer, or compact track loader into the same broad heavy-duty category, we evaluate factors such as:

• Machine make and model

• Engine horsepower

• Lift capacity

• Tracks versus wheels

• Machine or bucket width

• Mount type

• Primary jobs

• Frequency and severity of use
  

Our goal is not simply to provide a grapple that connects to your machine.

We recommend a grapple that is properly reinforced for the forces your machine can generate without adding unnecessary attachment weight. This machine-specific approach helps ensure your grapple is built to remain dependable through many years of demanding use. We also always ensure you are fit with the correct mount for your machine, couplers, and feedlines so that you can get right to work!
