AGCO - 4351267M1 - Multi-Ribbed Belt 4PK x 1159 Massey Ferguson

This multi-ribbed belt drives the air conditioning compressor from the engine crankshaft. It sits in the belt path on the front of the engine, transmitting power to the compressor pulley. A worn or glazed belt slips under load, reducing compressor speed and causing weak cooling output. The original belt matches the pulley groove profile and tension characteristics of the host tractor's drive system, ensuring proper engagement without squeal or excess vibration.
