Reynolds 572A Dirt Pan Scraper Design Function and Field Adaptation

[MikePhua]

The Reynolds Legacy in Earthmoving Innovation
Reynolds Scrapers, founded in Texas in the mid-20th century, built its reputation on durable, field-adaptable pull-type scrapers for agriculture and construction. The 572A dirt pan is part of their mid-size lineup, designed for precision land leveling, general earthmoving, and laser-controlled grading. Unlike self-propelled motor scrapers, the 572A is tractor-drawn, making it ideal for farms and contractors who need flexible, cost-effective solutions.
By the early 2000s, Reynolds had shipped thousands of units across North America, with the 572A becoming a popular choice for 100–150 hp tractors. Its compact footprint, hydraulic sequencing, and rugged build allowed it to operate in tight fields, soft soils, and tandem configurations.
Core Specifications and Mechanical Layout
The Reynolds 572A is a single-axle, rear-eject scraper with a heaped capacity of approximately 10 cubic yards (7.7 m³). It features:

• Cutting width: ~84 inches (2.13 meters)
  
• Transport width: ~99 inches (2.52 meters)
  
• Tire size: 13.5 x 16.1 (4 tires)
  
• Shipping weight: ~6,800 lbs (3,090 kg)
  
• Tractor requirement: ~130–180 hp
  

Its hydraulic system includes a front gate, bowl lift, and rear ejector, all sequenced to allow smooth loading and dumping. The cutting edge pivots with the bucket, maintaining consistent depth and reducing wear.
In one farm in Nebraska, a 572A was used to reshape terraces after spring runoff. The operator noted that the scraper’s compact width allowed him to work between fence lines without removing posts.
Hydraulic Plumbing and Tandem Operation
The 572A can be configured as a lead or trailing unit in tandem setups. When used as a lead scraper, its hydraulic system must be plumbed to control both its own functions and those of the trailing unit. This requires:

• Dual hydraulic outlets on the tractor
  
• Sequencing valves or diverter blocks
  
• Pressure-compensated flow control
  
• Return lines routed to a common reservoir
  

Operators often install quick couplers and color-coded hoses to simplify hookup. In one tandem setup in Iowa, a contractor ran two 572As behind a 200 hp tractor, using a custom manifold to synchronize gate timing and ejector speed.
Cutting Edge and Soil Behavior
The scraper’s cutting edge is replaceable and designed to penetrate compacted soils without excessive draft. It pivots with the bowl, allowing the operator to maintain grade even on undulating terrain.
Recommended edge materials:

• High-carbon steel for clay and loam
  
• Tungsten-carbide overlay for abrasive soils
  
• Serrated edge for sod and root penetration
  

In one project in Mississippi, a 572A was used to remove topsoil before pad construction. The operator switched to a serrated edge to cut through grass and roots, reducing clogging and improving fill quality.
Maintenance and Field Durability
Routine maintenance ensures long service life:

• Grease pivot points weekly
  
• Inspect hydraulic hoses for abrasion
  
• Check tire pressure monthly
  
• Replace cutting edge every 500 hours or when worn below 50%
  

Common wear points:

• Gate hinge pins
  
• Ejector slide rails
  
• Bowl lift cylinder seals
  
• Tire sidewalls from stubble or debris
  

A technician in Alberta extended the life of his 572A by installing bolt-on skid shoes and reinforcing the gate hinge with a gusset plate. After 2,000 hours, the scraper showed minimal structural fatigue.
Laser Grading and Precision Control
The 572A can be paired with laser grading systems for precision land leveling. This involves:

• Mounting a laser receiver on the scraper mast
  
• Connecting to a hydraulic valve controller
  
• Calibrating slope and elevation targets
  

Laser grading improves water runoff, crop uniformity, and pad accuracy. In one vineyard in California, a 572A was used to create uniform rows with ±0.25 inch elevation tolerance, improving irrigation efficiency.
Used Market and Retrofit Potential
Used 572A scrapers typically sell for $6,000–$12,000 depending on condition and configuration. Buyers should inspect:

• Hydraulic cylinder response
  
• Gate and ejector timing
  
• Cutting edge wear
  
• Frame welds and axle alignment
  

Some owners retrofit GPS receivers, LED work lights, and upgraded tires for better performance. In one case from Kansas, a farmer added a hydraulic accumulator to smooth gate movement during high-speed loading.
Conclusion
The Reynolds 572A dirt pan scraper remains a versatile and durable tool for land shaping, grading, and earthmoving. Its compact design, hydraulic sequencing, and adaptability to tandem and laser systems make it a valuable asset in both agriculture and construction. With proper maintenance and smart upgrades, the 572A continues to deliver precision and productivity across a wide range of soil conditions and terrain profiles.
