Four stage WTS technology:
High performance in varying crops and conditions
The WTS System adds to proven cylinder/walker technology:
An advanced single-drum system with an 11- step walker design and innovative Power Separator helps you thresh the toughest, weed infested crop without hesitation, while achieving excellent grain and straw quality.
A high inertia cylinder separates more grain from the start, minimising grain and straw damage. It’s 10-bar design evens the threshing load (and power demand) and reduces slug-feeding; it’s 660 mm diameter allows higher-impact separation at lower rotational speeds, with more torque for smoother operation and material flow. And because it’s the same width as the feederhouse, you can take full advantage of the entire drum width.
Stage 1: The large –inertia drum and long concave separation area (see preceding pages) can easily be set to perform in a wide range of crops and conditions. A speed differential between the crop and drum speed results in thorough initial separation.
Stage 2: A large-diameter beater provides excellent material handling and additional separation, as the second concave extends the separation area. The concave can also be adjusted to handle a wide variety of crops and conditions.
Stage 3: Long walkers provide excellent separation in difficult crops, gentle handling for higher straw quality, and lower power consumption. It’s the best solution for growers with varying crops and conditions. A grid design (see preceding pages) allows active grain capturing.
Stage 4: The John Deere Power Separator employs the same “pull and release” technique found on Cylinder Tine-Separation (CTS) Combines. As Straw is pulled over the walker grids, the tines comb the crop mat, opening channels for trapped grain to fall to the cleaning shoe. The Power Separator tines comb through the straw mat, accelerating the crop, and thinning out the straw layer. Ideal for heavy and dense crops.
The gentle but aggressive threshing and separation action results in long, easily baleable straw. Optimum straw recovery from the swath is easily achieved; ideal for livestock operations.
The advantages of Walker Tine-Separation (WTS) technology:
- The whole separation length is used to remove grain from the crop
- Full crop flow area used for threshing and separation (maximizing performance)
- Excellent grain and straw quality
- Low specific power requirement, lower fuel consumption
- Simpler adjustments, easy to fine-tune for maximum performance
- Easy to change from crop to crop
