Kooima Ag® Trner® Komposter

Composting offers several key benefits:

• Reduces organic waste and landfill use.
• Creates nutrient-rich soil amendments.
• Improves soil health and crop yields.
• Helps manage manure and agricultural byproducts efficiently.
• Supports sustainable and environmentally friendly farming practices.

A compost turner is a piece of equipment designed to mix, aerate, and reshape compost windrows. By turning the material regularly, the machine accelerates decomposition, ensures consistent moisture distribution, and produces uniform compost more efficiently.

Turning compost is essential because it introduces oxygen into the compost pile, which speeds up the decomposition process and prevents odors. A properly turned compost windrow breaks down faster, produces more consistent material, and creates higher-quality finished compost.

A Trner composter is Kooima Ag’s branded compost turner system designed to aerate and mix compost windrows efficiently. These machines are engineered for durability, performance, and ease of use in agricultural and commercial composting operations.

Kooima Ag compost turners and Trner composters can handle a wide range of organic materials, including:

• Livestock manure
• Crop residue
• Food waste
• Yard waste and green waste
• Biosolids (depending on application)

The main differences between Kooima Ag compost turners come down to size, capacity, and output:

• Skid Trner – Best for smaller operations or tight spaces.
• 10’ Trner Compost Trner – Ideal for medium-sized operations and comes with 3 hook-up options: a skid steer, payloader, or tractor.
• 14’ Trner Compost Trner – Built for large-scale, high-volume composting.
  • Choosing the right size depends on your windrow size, available horsepower, and production goals.

Yes—“Trner composter” and “compost turner” refer to the same type of equipment, but “Trner” is Kooima Ag’s branded product line.

• Because customers often search for “compost turner,” it’s important to understand that Trner composters are professional-grade compost turners designed for agricultural and commercial use.

To operate a compost turner or Trner composter, you typically need:

• A tractor or skid steer (depending on the model).
• Adequate horsepower for the size of the machine.
• A compost site with space for windrows.
• Additional equipment like loaders or screeners can help improve workflow but may not be required.

The best compost turner for your operation depends on:

• Volume of material you process
• Size of your windrows
• Available equipment (tractor horsepower or skid steer)
• Desired production speed
• For smaller farms, a skid-mounted unit may work best, while larger operations benefit from 10’ or 14’ turners for maximum efficiency.
