Product Overview

The TGEC box-style rock picker is a hopper-type attachment built to sweep rocks from farm fields, construction lots, and pasture ground. A rotating tine reel lifts rocks from the soil and deposits them into a large-capacity hopper; the full-open rear door dumps the entire load quickly into piles or hauling equipment.

Model TG-RP1830(72IN)-MP1140 delivers a 1,830 mm (72 in) working width, a 1,200 kg safe working load, and bi-directional rotation for clearing material in forward or reverse. The 1-inch thick high-carbon steel tines and No. 60 heavy-duty roller chain drive handle continuous field work. For operations that need soil screening alongside rock collection, our rotary rock picker offers a drum-based alternative. Browse the full Skid Steer Rock Pickers category for the complete lineup.

How It Works

Hydraulic flow from the skid steer auxiliary circuit drives a heavy-duty roller chain that rotates the tine reel at the front of the hopper. The tines sweep through the soil, lifting rocks and debris up and over the reel into the collection hopper while soil falls back through the tine gaps. Bi-directional rotation lets the reel run in reverse to clear jams or work in tight spaces, and the full-open hopper door releases the entire load in one motion when the skid steer arms raise the attachment.

Application Scenarios

  • Agricultural field rock removal before planting and tilling

  • Construction site cleanup and lot preparation

  • Pasture and rangeland rock collection for livestock safety

  • Road base and driveway preparation

  • Land reclamation and post-demolition debris sorting

  • Orchard floor cleanup and vineyard row maintenance

  • Farm drainage field and tile line rock clearance

Installation & Mounting

The TG-RP1830(72IN)-MP1140 mounts to any standard skid steer universal quick-attach plate (MP1140) without adapters. Connect the auxiliary hydraulic couplers to the picker's motor circuit, confirm that flow and pressure match the 75 L/min and 21 MPa specifications, and cycle the reel in both directions before entering the field. For machines with high-flow auxiliary circuits, install a pressure-reducing valve or set the in-cab flow limiter to avoid overspeeding the chain drive.

Wear & Service

The highest-wear components on a box-style rock picker are the tines, the roller chain, and the hopper floor. Inspect tines for bending or cracking before each shift, and check chain tension every 50 operating hours by deflecting the chain midway between sprockets. Lubricate all grease points daily, and inspect hydraulic hoses for abrasion near the mounting frame. Replace worn tines in matched sets to maintain balanced rotation, and keep spare chain links and hydraulic couplers on hand for field repairs.

OEM & Bulk Supply

TianGe supplies the box-style rock picker as a standard model and supports OEM customization including private-label branding, custom paint colors, alternative mounting plates, and modified tine spacing. Dealer and distributor bulk orders ship in consolidated containers with volume pricing, and each unit undergoes pre-shipment inspection including hydraulic pressure testing and reel rotation verification.

Which Rock Picker — Box-Style or Rotary — Fits Your Skid Steer and Field Work?

What's your primary job — hauling rocks off the field in bulk, or screening soil while collecting rocks? And what's your skid steer's auxiliary flow rating?

Frequently Asked Questions

What type of material is the Skid Steer Box-Style Rock Picker designed to collect?+

The box-style picker collects rocks, stones, and similar hard debris from soil surfaces. Its rotating tines lift material ranging from small gravel to large field rocks, and the hopper retains the collected load until dumping. It is not intended for fine soil screening or liquid slurry handling.

What skid steer hydraulic flow is required for this rock picker?+

The TG-RP1830(72IN)-MP1140 requires 75 L/min of auxiliary hydraulic flow. Verify that the skid steer provides the required 75 L/min auxiliary hydraulic flow. High-flow machines should use a flow limiter or pressure-reducing valve to prevent overspeeding the chain drive and premature wear.

What operating pressure does the rock picker require?+

The rock picker operates at 21 MPa system pressure. Verify that the skid steer auxiliary circuit meets the required 21 MPa operating pressure before use. Excess pressure can damage the hydraulic motor and chain drive, while insufficient pressure reduces reel torque and picking performance.

How does the bi-directional rotation system work?+

The hydraulic motor drives the tine reel in both forward and reverse directions through the roller chain. Forward rotation lifts rocks into the hopper during normal picking. Reverse rotation clears material jams, backs out wedged rocks, and allows operation in confined spaces where forward-only movement is impractical. Direction is controlled from the skid steer cab via the auxiliary hydraulic circuit.

How does the full-open hopper assist with dumping collected rocks?+

The full-open hopper uses a rear door that swings completely open when the skid steer arms raise the attachment. This eliminates restricted discharge openings found on some hopper pickers, allowing the entire rock load to exit in one motion without hang-ups. It reduces dumping cycle time and prevents material from wedging inside the hopper, especially useful with large, irregularly shaped field rocks.

What type of steel is used for the rock picker tines?+

The tines are manufactured from 1-inch (25.4 mm) thick high-carbon steel in solid, one-piece construction. High-carbon steel provides the hardness and abrasion resistance needed for continuous contact with rocks and soil, and the solid cross-section resists bending under heavy loads. Tines are replaceable and should be inspected regularly for wear and cracking.

What mounting system does the rock picker use?+

The picker uses the MP1140 universal quick-attach mounting system, designed for standard universal quick-attach systems on skid steer loaders. No adapter plate is required for standard machines. For skid steers with non-standard mounting interfaces, TianGe can supply custom adapter plates through its OEM program.

How should the tines and drive chain be inspected during operation?+

During operation, listen for unusual knocking or grinding from the reel area, which may indicate a bent tine hitting the hopper frame or a loose chain. Stop periodically to visually inspect tines for bending, cracking, or excessive wear at the tips. Check chain tension by pressing on the chain midway between sprockets. If the chain slaps the frame or the reel jerks under load, stop and retension or replace the chain before continuing.

What operating conditions can affect rock-picking performance?+

Performance is affected by soil moisture, rock size and density, ground speed, and reel rotation speed. Wet or clay-heavy soil can stick to tines and reduce separation, while very dry, loose soil may allow small rocks to fall back through. Ground speed should be matched to rock density; slower speeds in heavy rock fields allow the tines to fully engage. Excessively high reel speed can throw rocks out of the hopper rather than depositing them, while too little speed fails to lift larger stones. For guidance on matching configuration to conditions, see our rock picker selection guide.

What wear parts should operators monitor on a box-style rock picker?+

The primary wear parts are the high-carbon steel tines, the No. 60 roller chain and sprockets, the hopper floor and rear door hinges, and the hydraulic motor seals. Tines wear fastest at the tips and should be replaced when they show excessive wear. The chain stretches over time and should be replaced when tension adjustment reaches its limit. Sprockets should be replaced with the chain to prevent accelerated wear. Hopper floor abrasion can be addressed with wear plating, and hydraulic seals should be replaced at the first sign of leakage. For a complete service schedule, refer to our configuration comparison which includes maintenance notes for both picker types.
