Why ABI Ground Drive Outlasts Competitors: Five Construction Advantages
ABI makes a direct claim that the horse manure spreader will outlast any competitor. Here's how the construction backs that claim:
What Makes 12-Gauge Corten Steel Better Than Mild Steel?
The answer is corrosion resistance and structural integrity.
Most competitors build with 16-gauge farm-grade mild steel and bolt-together frames. ABI uses 12-gauge Corten steel throughout, which is:
- Corrosion-resistant even when unfinished and exposed to the elements
- Fully welded rather than bolted, eliminating joints that loosen under vibration and daily stress
- Significantly heavier: The ABI Ground Drive weighs nearly a third more than equivalently sized competitor spreaders because of this construction
Key Fact: That extra weight is tangible evidence of better materials and better build quality. Heavier means more durable.
Why ABI Chooses PPG AUE-370, Not Rust-Oleum or Powder Coat?
PPG AUE-370 is the better choice for combining field repairability with commercial-grade coating chemistry.
Here's why:
Powder coat disadvantages:
- Requires specialized equipment (electrostatic gun, oven re-bake) to re-powder-coat. Field touch-ups are possible only via a separate liquid repair system, not the original coating process.
- Larger chipped areas typically need full stripping and recoating rather than a spot repair
- If moisture reaches bare metal through a chip, corrosion can spread underneath the coating
- Color-matching a field touch-up is difficult without specialty products
Rust-Oleum disadvantages:
- A one-component (1K) alkyd enamel, which cures through a slower air-drying oxidation process rather than the direct two-component chemical reaction used in polyurethanes
- One-component alkyd systems generally offer lower chemical and abrasion resistance than two-component polyurethanes
- Lower gloss and color retention over time compared to two-component polyurethane systems
- Formulated as a general-purpose retail coating, not an OEM-specified commercial coating system
PPG AUE-370 advantages:
- Two-component polyurethane chemistry, chemically crosslinked for superior chemical resistance, abrasion resistance, and film integrity versus one-component enamels
- Liquid, direct-to-metal application supports field touch-up without an oven or specialty equipment
- Part of PPG's Commercial Performance Coatings line, used by custom coaters and equipment manufacturers
- Applied after sandblasting per its technical specification, for proper adhesion
ABI's process: All steel components are sandblasted before coating, per AUE-370's technical requirement for an abraded, contaminant-free surface. The coating used is PPG AUE-370, a direct-to-metal two-component polyurethane, not powder coat or a single-component retail enamel.
What Is Coal Tar Epoxy and Why Does It Matter?
Coal tar epoxy is an industrial-grade liner that protects against the acids in manure and urine.
The inside of the spreader box is coated with the same material that lines:
- Underground sewage tanks
- Industrial pipelines
- Ship hulls
What it does:
- Seals the box interior against manure acids and urine
- Provides industrial-grade abrasion resistance
- Adds a third layer of protection on top of Corten steel and PPG AUE-370
Key Fact: This is the same coating used in the harshest corrosive environments. It's overkill for a manure spreader, which is exactly why it lasts.
Why Does the Floor Have a Lifetime Warranty?
Because it's built from polyvinyl lumber that will not rot, rust, or warp.
The floor construction uses:
- Thick tongue-and-groove polyvinyl lumber
- Tongue-and-groove locking system that prevents warping
- Lifetime warranty on the flooring material
Why this matters:
- Warped floors bind apron chains on cheaper spreaders
- Polyvinyl reduces wear on the apron web over years of daily use
- You'll never replace a rotted floor
Key Fact: The tongue-and-groove construction locks individual boards together, eliminating the warping that causes maintenance headaches on competitor models.
What Does "Hand-Built by Skilled Craftsmen" Actually Mean?
It means each ABI Ground Drive is assembled by experienced spreader craftsmen who validate quality at every step.
Here's what that looks like in practice:
- Mechanical components chosen for durability and serviceability, not just cost
- Overall construction standard validated by unit weight: heavier means better materials and better build
- At nearly a third more weight than comparable competitors, the difference is something you can feel when you look at the machine
Key Fact: ABI doesn't automate assembly to cut costs. Each spreader is built by craftsmen who know how these machines fail in the field and build them not to.
Spreading Performance: How the ABI Ground Drive Works
A small horse spreader isn't just about hauling manure, it's about spreading it in a way that supports pasture health. Here's how the ABI Ground Drive delivers controlled, consistent performance:
Four-Speed Variable Flow Control
What it does:
The apron chain that feeds manure toward the beaters runs at four adjustable speeds, independent of how fast your tow vehicle moves.
Why it matters:
- Slow the feed rate for light, controlled applications on pastures you want to protect
- Speed it up to empty fast across a larger field
- Adjust for different manure types: consistency changes with bedding material, stage of decomposition, and weather
Key Fact: Having four speeds gives you the adjustment range to handle wet manure, dry manure, and everything in between without clogging or uneven spreading.
Two Beater Bars With 32 Shredding Blades
What it does:
- First beater: 32 shredding blades with a shredder hood that forces manure into the blades before it reaches the spreading beater
- Rear beater: Further breaks down material and distributes it evenly over a wide swath
Why it matters:
- Shredded manure exposes more surface area to sunlight, accelerating decomposition
- Reduces clumps that burn vegetation, breed flies, and prevent pasture regrowth
- Enables eco-balanced pasture management (see next section)
Key Fact: Owning a spreader that shreds before it spreads and controls application rate makes it possible to actively manage pasture health rather than just dispose of waste.
Advanced Ground Drive System
How it works:
- Right wheel drives the apron chain
- Left wheel drives the beater bars
- Both wheels work in unison for maximum traction, similar to a locking differential on a truck
- Ratcheting hubs allow wheels to move in reverse without engaging mechanisms
Why it matters:
- Prevents damage when backing up and keeps chains on sprockets
- Maintains consistent operation during tight turns
- Works on frozen or uneven ground without slipping or binding
Key Fact: This independent dual-drive system is what allows the ABI Ground Drive to maintain consistent spreading performance in conditions that would stall or damage simpler spreaders.
Eco-Balanced Pasture Benefits: Why Spreading Quality Matters
What Is an Eco-Balanced Pasture?
An eco-balanced pasture is one where manure is applied in a thin, evenly shredded layer that decomposes quickly rather than sitting in clumps.
The benefits:
- ✓ Reduces colic risk by minimizing parasite loads in pastures
- ✓ Increases how quickly pastures are available for grazing after spreading
- ✓ Produces more vigorous grass growth by distributing nutrients evenly
- ✓ Reduces flies and odor around the barn and in pastures
How Does the ABI Ground Drive Support Eco-Balanced Pasture Management?
The answer is controlled application rate and consistent shredding quality.
Here's how the features work together:
Four-speed apron control:
- Lets you apply thin layers instead of dumping heavy loads
- Prevents over-application that burns grass and creates anaerobic clumps
Dual 32-blade shredding beaters:
- Break manure into small particles that decompose in days, not weeks
- Expose more surface area to sunlight and oxygen
- Eliminate clumps that smother grass and breed flies
Key Fact: Properly managed manure isn't waste… it's a pasture fertility tool. The ABI Ground Drive Manure Spreader gives you the control to use it that way.
Easy to Maintain, Easy to Use
How Do Greaseable Bearings Make Maintenance Easier?
Greaseable bearings can be maintained regularly to significantly extend their useful life.
The difference:
- Bearings without grease zerks have a fixed service life and cannot be extended
- Bearings with grease zerks can be serviced to last years longer
ABI's approach:
- ✓ Greaseable bearings throughout the spreader
- ✓ Clearly marked grease zerks on the machine
- ✓ Extension tubes on hard-to-reach locations so maintenance stays practical
- ✓ Safety shields designed to allow access to grease points without removal
Key Fact: Regular greasing takes minutes and can double or triple bearing life. ABI makes it easy enough that you'll actually do it.
What Makes Daily Use Easier?
Swing-away jack stand:
- Makes hooking up and unhooking effortless
- No wrestling with the hitch
Easy-pull engagement levers:
- Simple to operate
- On some tow vehicles, can be operated from the seat
Rear bumper bar:
- Protects beater paddles when backing into storage
- Prevents damage from accidental contact
Customer support:
- Available Monday through Friday, 8 a.m. to 8 p.m. Eastern
- After-hours support available
- All parts kept in stock
Key Fact: ABI designs for the reality of daily use, not just the spec sheet.
Optional Accessories for Barn Use
Three options are available for facilities where barn layout makes loading and maneuvering more challenging:
Wheel Jack Stand
What it does: Allows the spreader to be moved by hand in and out of a barn or into a tight storage area
Best for: Facilities with narrow barn aisles or limited tractor access
Manual Ingate
What it does: Closes off the back of the spreader to prevent spillage during loading and transport through the barn
Best for: Operations that load inside the barn and need to move the spreader through clean areas before reaching the field
Fines Pan
What it does: Catches small manure particles that would otherwise fall out before reaching the beater bar
Best for: Facilities that need to keep barn aisles and driveways clean during transport
