About this product
📘 Overview
The ANBO GR300-12 is a root rake for dozer rated to 300 horsepower, supplied in 3 widths from 93" to 119" on 12-inch tine spacing. It is built for wheel loaders, dozers and high-horsepower tractors up to 300 horsepower. 12-inch spacing is the widest spacing ANBO offers in this series — it drops nearly all soil and fines, so the load that reaches the pile is timber rather than dirt, which makes the GR300-12 the choice for stumps, large timber and high-volume land clearing. The GR300-12 uses heavy rake-bar tines in 1.25" AR400F steel, with a clamshell top grapple that closes over raked material so a load can be back-raked, gripped and carried in one pass. The choice you make on this listing is width — 93", 106", 119" — and it drives attachment weight from 3,988 lb up to 4,711 lb, so pick the widest unit your loader can still lift full. Every ANBO grapple is built in Colville, Washington from American AR400F steel, ships with a mount fabricated for your own machine plus hoses and couplers, and carries a two-year attachment warranty with three years on the cylinders.
⚙ GR300-12 Key Features
- Rated to 300 horsepower — ANBO sizes each model to the machine, so the GR300-12 is matched to loaders and tractors up to 300 hp rather than sold by width alone.
- 12-inch tine spacing — drops nearly all soil and fines, so the load that reaches the pile is timber rather than dirt.
- 1.25" : 1" AR400F tines — outer to inner tine thickness on the GR300-12, in steel with a 150,000–180,000 PSI yield strength against 32,000 PSI for A36.
- 90" grapple opening — the jaw span of the GR300-12 when the clamshell is open.
- 4"x 14" hydraulic cylinders — fully welded, rear mounted and rated to 3,000 PSI, with a built-in pressure relief valve on the larger units to protect the machine's hydraulics.
- Clamshell design with a top grapple — the top bar closes over raked material, so the unit rakes, digs, grips and back-rakes without an attachment change.
- Greaseable, accessible pivot points — every pivot takes grease and can be reached without dismantling the rake.
- 2-wire R-16 hoses rated to 5,800 PSI — routed securely, with hose wrap offered to protect the supply lines.
- Two-piece mount, engineered position — most ANBO mounts are two-piece, keeping the center of the rake open for visibility; mount location and angle are set to work on both tractors and skid steers.
- Made in the USA from American steel — designed, fabricated and assembled in Colville, Washington.
🔑 Why Buyers Choose the GR300-12
- A 3,988 lb attachment on a 300 hp machine leaves lift capacity for the load — AR400F is five times stronger than grade 36, so ANBO reaches the required strength without the extra plate thickness that a mild-steel grapple needs. The 93" GR300-12 weighs 3,988 lb; the weight you do not spend on the attachment is weight you can still pick up.
- 12-inch spacing decides what stays in the load — on the GR300-12 it drops nearly all soil and fines, so the load that reaches the pile is timber rather than dirt, which is why this spacing is the one to pick for stumps, large timber and high-volume land clearing.
- The top grapple lets you back-rake and carry in the same pass — material raked up is clamped and moved without swapping to a bucket, which removes a machine trip per pile.
- Greaseable pivots instead of sealed or welded ones — the wear points on the GR300-12 can be serviced on schedule, which is what decides whether a grapple lasts a season or a decade.
- Three years on the cylinders, one more than on the attachment — ANBO warrants the highest-wear hydraulic component for longer than it warrants the frame.

This listing covers the GR300-12 — tine spacing is fixed at 12" Tines across every part number on the page. The width option is the selection you make at checkout:
- 93" — part number GR300-12-93, 3,988 lb attachment weight
- 106" — part number GR300-12-106, 4,346 lb attachment weight
- 119" — part number GR300-12-119, 4,711 lb attachment weight
A wider GR300-12 covers more ground per pass but adds 723 lb between the narrowest and widest unit. Match the width to what your loader can lift full, not to the widest unit offered.
🔗 What Is the ANBO GR300-12 Used For?
ANBO builds the Grapple Rake line for stumps, large timber and high-volume land clearing. On the GR300-12 specifically, the jobs it is bought for are:
- Wheel-loader and dozer land clearing
- Heavy stump and root removal
- Large timber handling
- Bulk debris and slash moving
- Large-scale site preparation
The GR300-12 ships complete and ready to run — the grapple, the mount built for your machine, hoses and couplers.
Buyers shop this class of attachment under several names. Root grapple attachment and skid steer rock rake both describe what the GR300-12 is — a clamshell rake that grips. If your search started with root rake grapple, root grapples or root rake for tractor, the GR300-12 is the 300-horsepower unit in that family.
🚜 Which Machines Fit the ANBO GR300-12?
The ANBO GR300-12 is built to order with a mount made for your specific machine. It is not a fixed-interface attachment: ANBO fabricates the mount to the loader, tractor or skid steer you name when you order, so fitment is confirmed at build time rather than assumed from a standard.
Fitment factor ANBO GR300-12 Machine horsepower Up to 300 hp — this is the primary fitment limit on the GR300-12 Machine types Wheel loaders, dozers and high-horsepower tractors up to 300 horsepower Grapple opening 90" — the largest single piece the GR300-12 will close on Mount Custom-built to your machine. Universal skid steer quick attach and John Deere are the common options; ANBO builds most other mounts as well Mount construction Two-piece on most units, which keeps the center of the rake open for visibility. Build-backs reduce lift capacity and are only used where a machine requires one Hydraulics required One double-acting auxiliary hydraulic circuit to open and close the grapple. Cylinders are rated to 3,000 PSI Supplied with Mount, hoses and couplersHorsepower is the deciding number, not width: ANBO names each model for the machine size it is built for, and running a 300-hp-rated grapple behind a bigger machine is what bends attachments. You do not need to check with us first: the order page asks for your machine make and model, we build the mount to it, and we verify fitment before the unit ships.
❓ ANBO GR300-12 Questions, Answered
What size machine does the ANBO GR300-12 fit?
The ANBO GR300-12 is rated for wheel loaders, dozers and high-horsepower tractors up to 300 horsepower. ANBO names each model for the machine size it is built for, so a 300-hp rating is a ceiling rather than a suggestion: putting a larger machine behind the GR300-12 is the most common way a grapple gets bent.
Which width of the GR300-12 should I order?
The GR300-12 comes in 3 widths from 93" to 119". Attachment weight runs from 3,988 lb at 93" to 4,711 lb at 119", so the limit is what your loader can still lift once the grapple is full. A wider unit clears more ground per pass; a narrower one leaves more of your rated capacity for the load.
Why does the GR300-12 use 12-inch tine spacing?
12-inch spacing is the widest spacing ANBO offers. On the GR300-12 it drops nearly all soil and fines, so the load that reaches the pile is timber rather than dirt. That is what makes this the right unit for stumps, large timber and high-volume land clearing — spacing decides what stays in the load and what falls back on the ground.
What hydraulics does the ANBO GR300-12 need?
The GR300-12 needs one double-acting auxiliary hydraulic circuit to open and close the clamshell. The cylinders are fully welded, rear mounted and rated to 3,000 PSI, and the hoses are 2-wire R-16 rated to 5,800 PSI. The larger ANBO units include a built-in pressure relief valve to protect your machine's hydraulic system.
Does the GR300-12 come with a mount for my machine?
Yes. ANBO builds the mount for the specific machine you name at order time and the GR300-12 ships complete with mount, hoses and couplers. Most ANBO mounts are two-piece, which keeps the center of the rake open so you can see the load. Tell us what you are running when you order and the mount is built to it.
What is AR400F steel, and why does ANBO use it?
AR400F is an abrasion-resistant alloy with a yield strength of 150,000–180,000 PSI against 32,000 PSI for A36 mild steel — roughly five times stronger. The F is for formability: it is less brittle than standard AR400, so it bends rather than cracking under shock load. Because the steel is stronger, the GR300-12 does not need the extra plate thickness a mild-steel grapple uses, and the weight saved stays available as lift capacity.
What warranty comes with the ANBO GR300-12?
ANBO provides a two-year manufacturer defect warranty on the attachment from the date of delivery to the original purchaser, and three years on the cylinders. The warranty does not cover use beyond rated capacity, misuse, unauthorized modification, or normal wear on ground-engaging tines. For a warranty question on a GR300-12 bought from us, email support@eskidsteer.com.
What servicing does the GR300-12 need?
Grease every pivot point on schedule — ANBO makes all pivots greaseable and accessible on the GR300-12 so this can be done without dismantling the rake. Check the hose routing and the hose wrap for abrasion, and inspect the tines for wear. Tines are ground-engaging parts and wear is not a warranty item.
Should I get the 12" GR300 or a wider tine spacing?
eskidsteer.com stocks the GR300 in 12" as well as 8". The 12" GR300-12 drops nearly all soil and fines, so the load that reaches the pile is timber rather than dirt. A wider spacing sheds more soil and fines, which is what you want when you are moving timber and brush rather than picking rock. Spacing does not change the machine rating — every GR300 is built for machines up to 300 horsepower.
Can my loader actually lift the GR300-12?
The GR300-12 weighs 3,988 lb at 93" and 4,711 lb at 119" before you pick anything up, so check your machine's lift capacity at full reach, not just its horsepower rating. Machines in the 300-horsepower class carry it; if you are near the bottom of that range, order a narrower width.
How big a piece can the GR300-12 pick up?
The GR300-12 has a 90" grapple opening, which is the largest single piece the clamshell will close on. Anything larger has to be cut or handled in the rake rather than gripped.
Is root grapple attachment the same thing as the GR300-12 grapple rake?
Root grapple attachment and skid steer rock rake are two names for the class of attachment the GR300-12 belongs to — a loader-mounted clamshell that rakes and grips. ANBO calls the GR300-12 a grapple rake because the lower tines rake and dig while the top grapple closes over the load. If your search started with root rake grapple or root grapples, the GR300-12 is the 300-horsepower unit in that family.
How is the ANBO GR300-12 shipped and how much is freight?
The GR300-12 ships by LTL freight. Shipping is calculated at checkout — add the width you want to your cart, enter your delivery address, and the shipping charge is shown before you complete the order. Lift gate service is available for residential deliveries and can be selected at checkout.
How do I order the ANBO GR300-12?
Add the GR300-12 width you need to your cart and check out online — that is the whole process. The order page asks for your machine make and model; we build the mount to that machine and verify fitment before it ships, so there is no need to call ahead or wait on a quote. If you would rather ask something first, use the chat button on any eskidsteer.com page or email support@eskidsteer.com.
