Question 1

What is a CVX transmission?

Accepted Answer

The CVX (Continuously Variable Transmission) is a continuously variable transmission system with no fixed gear ratios. It combines a hydrostatic variator with a mechanical epicyclic gear train to provide perfectly linear speed progression from 0 km/h up to maximum engine speed, without any loss of traction. The operator sets a target travel speed; the system automatically adjusts the hydrostatic/mechanical ratio based on load and engine speed to reach it with optimal efficiency. On Case IH tractors (Puma CVX, CVX 130, Maxxum 130 CVX), this translates to optimized fuel consumption during plowing and reduced operator fatigue during transport. TMC Bejenne stocks used CVX gearboxes from these models, inspected before shipment.

Question 2

What is a Powershift transmission?

Accepted Answer

A Powershift transmission is a load-shift gearbox allowing gear changes without interrupting traction. It uses electronically controlled wet multi-disk clutches that engage and disengage sequentially during gear shifts, eliminating the need for the driver to operate a clutch pedal. The result is almost seamless shifting, maintaining traction even under maximum load. Case IH Maxxum (ActiveDrive 4) and higher ranges (ActiveDrive 8 / DKT) feature Powershift managed by the gearbox electronics (TCU), selecting the optimal gear based on speed, load, and operator input. These gearboxes require rigorous oil maintenance (Hy-Tran Ultra) and regular clutch calibration to preserve performance.

Question 3

Why choose Case IH for your tractor or combine?

Accepted Answer

Case IH is one of the leading brands in large cereal farms and French CUMA cooperatives, offering a comprehensive range covering tractors from 60 to over 400 horsepower (Farmall, Maxxum, Puma, Optum, Magnum series) and Axial-Flow combines (AF 5, AF 6, AF 8, AF 9). The Axial-Flow longitudinal rotor design is especially valued on large plots for its high throughput and reduced losses on dense cereals. The AFS platform (Advanced Farming Systems) integrates GPS guidance, yield mapping, and remote telemetry since the first models in the series. For farms already equipped with Case IH machinery, the logistical advantage of shared parts (transmissions, axles, hydraulics) across models is significant. TMC Bejenne has stocked Case IH used parts for all these ranges since 1945.

Question 4

Which is the most powerful Case IH tractor?

Accepted Answer

Among the current lineup, the most powerful Case IH tractor is the Magnum AFS Connect, with top versions delivering around 400 horsepower including temporary boost. This large six-wheel-drive row-crop tractor (optional) is designed for deep tillage, strip-till, and heavy equipment transport. Previous generations include the Magnum 250 (available in our used transmission stock), a common reference for large farms. For combines, the Axial-Flow 9240 is the brand’s premium reference, with header widths up to 12 meters.
