The first and only Laverdan cylinder combines were the MX 240 and MX 300 introduced in 1986. The model number indicated the power rating in horsepower. Both models had a 13.8-liter engine, with the more powerful one being turbocharged. The drivetrain was hydrostatic. The cutting width was 480, 540, 600, or 660 cm. The cutting height adjusted automatically, and as an optional extra, the reel speed could be linked to the forward speed.

In Laverdan’s solution, instead of a threshing drum, there was a 260 cm wide cylinder positioned transversely. The grain was directed to the right edge of the cylinder, which had a 104 cm wide threshing reel section. The other edge of the cylinder replaced the walkers and was 155 cm wide. From there, the grain traveled a long way through the straw walker conveyor, a 4-meter auger, distribution augers, an acceleration drum, and a pre-cleaner before reaching the sieve area. The purpose of the distribution augers was to spread the material evenly across the entire width of the sieving area. Under the acceleration drum was a pre-cleaner, which was claimed to remove most of the straw and debris. Below that was a traditional sieve area, tilted at 20 degrees for slope threshing.

The structure left plenty of space for the grain tank, which had a capacity of 9,000 liters. The cab included, among other things, air conditioning, a threshing loss monitor display, and a control system with 29 functions. Sales of the MX apparently remained limited, as they have not appeared on sales lists.
