Why Farms Choose the YK-5552A Round Baler

Unlike tractor-dependent PTO balers, the YK-5552A runs on its own diesel engine. That means you can start baling even when tractor access is limited. The integrated belt conveyor feeds material smoothly, while the PLC control system automates bale formation, wrapping, and ejection.

  • Self-powered: 17HP diesel engine eliminates the need for tractor PTO.
  • Balanced density: 500–750 kg/m³ bale density for stable fermentation.
  • All-in-one: Includes belt conveyor and air compressor — ready to work.
  • Smart control: PLC system with automatic bale counting and wrap timing.

How It Works

Four simple steps from raw forage to sealed silage bale.

1

Feed

Load cut forage onto the conveyor belt manually or from a chaff cutter.

2

Bale

PLC-controlled chamber rolls and compresses material into a 550mm round bale.

3

Wrap

The bale is automatically wrapped with stretch film for airtight silage fermentation.

4

Discharge

Finished bale is ejected onto the ground, ready for storage or transport.

Frequently Asked Questions

A round silage baler produces cylindrical bales that shed water naturally and are easier to wrap and store outdoors. A square baler produces rectangular bales that stack tightly for transport and indoor storage. Round balers are preferred for silage and wet forage because they bale faster and the wrapped round bale ferments evenly.
Yes. The YK-5552A is a combined baler-wrapper machine. It can bale with net or twine and then automatically wrap the bale with stretch film for silage fermentation. The switch between net and film is quick and tool-free.
The YK-5552A is equipped with its own 17HP diesel engine, so it can operate independently without a tractor PTO. This makes it ideal for small farms, cooperatives, and rental services where tractor power is limited.
