What to Look for in a Silage Trailer (NZ Farmer’s Guide)

When it comes to modern farming in New Zealand, efficiency and reliability are key. One piece of equipment that makes a big difference during harvest season is the silage trailer. Whether you’re working with maize, grass, or other forage crops, the right trailer helps you transport feed quickly and safely.

What Is a Silage Trailer?

A silage trailer is a purpose-built farm trailer designed for carrying chopped forage from the paddock to the storage site. Unlike standard tipping trailers, silage trailers are built with high sides, large capacity, and strong construction to handle bulky loads without spillage.

For New Zealand farms—where efficiency during short harvest windows is crucial—silage trailers help keep operations moving smoothly.

Key Features of a Good Silage Trailer

When choosing a silage trailer in NZ, here are a few things to look out for:

• High Sides & Capacity – Most silage trailers in NZ range from 20–40 cubic metres, giving plenty of room for forage.
• Strong Chassis & Build Quality – Built to withstand New Zealand’s tough farm conditions and heavy loads.
• Hydraulic Tipping System – For quick unloading at the silage pit.
• Wide Tyres or Flotation Tyres – To reduce soil compaction when operating in wet paddocks.
• Safety & Stability – Braking systems, sprung drawbars, and proper balance are important when towing on hilly terrain.

Why Farmers in New Zealand Use Silage Trailers

Silage trailers are more than just a convenience—they’re an investment in farm efficiency. Some benefits include:

• Faster Harvesting – Large-capacity trailers mean fewer trips between paddock and pit.
• Better Feed Management – Designed for bulk forage, reducing wastage and spillage.
• Durability – Made to last for many seasons under heavy use.
• Adaptability – Can be used for other bulk materials like straw, woodchips, or compost when not in silage season.

Silage Trailers vs Standard Farm Trailers

While standard tipping trailers are versatile, they’re not always the best for forage. Silage trailers have higher sides and greater volume, making them more efficient when handling light but bulky crops. This means fewer trips, less fuel, and less time spent on the job.

Choosing the Right Silage Trailer in NZ

When deciding on a silage trailer, consider:

• Farm size and cropping area – Larger operations often benefit from high-capacity trailers.
• Terrain – If you farm on rolling or steep country, stability and braking systems are crucial.
• Tractor horsepower – Make sure your tractor has enough pulling power for a fully loaded trailer.
• Local service and support – Buying from a trusted NZ supplier means access to parts and backup when needed.
