Claas Trion: combine harvester series, power classes and what to look for when buying
Claas Trion — a series of combine harvesters for medium and large farms, produced since 2021. In this article, we review the main versions, the threshing system, and what to check when buying a used combine harvester.
Trion in brief
Trion — conventional combine harvesters with walker straw walkers. They are designed for harvesting grain, rapeseed, corn (with the appropriate header) and other crops.
The series partly replaces the previous Tucano and Avero series. It offers several power classes — from smaller to very powerful models, whose class is indicated by a three-digit number (e.g., 530, 730 or 760).
Which version to choose
Smaller Trion models are suitable for medium-sized farms that need a versatile combine harvester with a relatively low price compared to larger models. They often have a smaller grain tank and narrower cutting width.
Larger classes (700 series) are designed for large farms and service providers. These models are more powerful, usually have a more powerful engine and a larger grain tank. Tracked Terra Trac versions are also available, which cause less soil compaction.
Engines and threshing system
The engines meet Stage V requirements, which means SCR with AdBlue. Always check the exact power and engine type according to the specific combine harvester's documents.
The threshing system is based on a cylinder and walker straw walkers. Additional yield and moisture measurement systems, GPS control, and automatic setting adjustments are also offered.
What to check when buying a used Trion
Since the series is new, there aren't many used examples around. The key thing is the engine and cutter bar hours. Ask for the readings of both meters and compare them with the usage history.
Inspect the cutter bar and concave: wear should be even. Check the belts, grain unloading slide, and tension of belts and chains.
For header versions, inspect the headers and reel. Ensure the cutter bar (if purchased together) is compatible with the combine and has no damage.
Versions and Series
Names and equipment vary by market and year; we provide a general overview by power classes.
Trion 500 serija
From 2021Lower power class combines for medium-sized farms.
- Often — a smaller grain tank
- More compact dimensions
- More affordable price
Trion 600 serija
From 2021Mid-range power class — a versatile choice for large and medium-sized farms.
- Greater efficiency than the 500 series
- Often — a wider cutter bar
- Often — enhanced automatic features
Trion 700 serija
From 2021Highest power models — for large farms and service providers.
- The most powerful in the series
- Often — a larger grain hopper
- Often — an extended control system
Trion Terra Trac
From 2021Tracked version — lower ground pressure, better traction.
- Tracks instead of front wheels
- Lower soil compaction
- More expensive maintenance
Comparison of three series
| 500 serija | 600 serija | 700 serija | |
|---|---|---|---|
| Who it's for | For medium-sized farms | For medium and large farms | For large farms and service providers |
| Power | Average | Higher | Largest |
| Tank | Smaller | Average | Largest |
| Control | Standard | Extended | Extended, more automation |
| Price in the used market (relatively) | Mid-range | High-end | High-end |
For average-sized farms, opt for a 500 or 600 series model, while larger plots might benefit from the 700 series if the budget allows. Terra Trac is ideal for those who prioritise traction.
Pros
- New generation with Stage V engines
- High efficiency and automatic setting adjustment
- Wide range of models to choose from
- All-wheel-drive version available
Cons
- Few used examples mean high prices
- Complex electronics — repairs are expensive
- Long wait times for parts and services possible
Frequently asked questions
How does the Trion differ from the Tucano?
The Trion is a newer series that partly replaced the Tucano. It features updated engines to meet Stage V requirements, a more modern control system, and more automated functions.
Is the Trion suitable for corn harvesting?
Yes, with the right corn header, the Trion can harvest corn. Before buying, it's worth checking if the combine and header are compatible.
Is it worth choosing the Terra Trac version?
Terra Trac tracks put less pressure on the soil and perform well in wet conditions, but they are more expensive and require additional maintenance. If soil condition is important in your operation, it's a good investment.
