Let’s look at the raw data. The New Holland Clayson M122 is a , but unlike the single-rotor system of an IH Axial-Flow, the M122 uses two parallel, side-by-side rotors. The was a significant model in the evolution

The was introduced as an evolution of the earlier M100 series, offering increased throughput, a more comfortable cab, and improved separation technology. It was designed to compete with combines from Claas (Dominator series), John Deere (1000 series), and Massey Ferguson (MF 500 series). Production of the M122 continued until the late 1980s, when it was replaced by the TX series (e.g., TX32, TX34) and later the CX series.

The heavy-duty poly-V belts driving the twin rotors are under immense stress. If you hear squealing or experience rotor stall in heavy crop, inspect these belts immediately. Replacement is tedious but not complex. Pro tip: Always keep a spare belt in the grain tank. To understand the M122, one must understand the
