This category is built for the Shandong Swan 4MZD-6 six-row cotton picker recorded in the supplier catalog. The current compressor is a 10K15F configuration with a 24V coil, eight-rib clutch near 125 mm, wide mounting arrangement, rear-facing flare ports and foot sleeves. These combined details define the present aftermarket sourcing scope.
Shandong Swan, 4MZD-6 and cotton picker together reduce confusion with generic agricultural compressors or unrelated equipment carrying a similar model family.
Harvest equipment operates in a seasonal maintenance window where a near-match can be costly. A common 10PA17C agricultural unit may differ in body, drive, mounting and hose head from this 10K15F build. Category placement under agricultural machinery describes the sector, while the leaf preserves the specific Swan cotton-picker buying intent.
Tractor, combine and other cotton-picker applications stay separate unless supplier evidence proves the same complete compressor configuration and the user approves broader coverage.
Confirm eight grooves, outside diameter, offset, bearing condition, connector and 24V coil. Inspect belt alignment and the accessory drive before removal. Cotton debris and dust can hide labels or wear patterns, so clean the old unit carefully and retain clear side photographs for supplier comparison.
It prevents one major error, but connector design, lead position, clutch resistance and the rest of the mechanical configuration still require inspection.
Rear-facing flare connections determine hose approach and service clearance. Confirm suction and discharge size, thread, sealing surfaces and head orientation. Do not replace a flare connection with an O-ring style or rely on an adapter without qualified system review, because sealing method and available space are part of the compressor identity.
Sleeves affect bolt fit, alignment and vibration control. Missing or different sleeves can move the compressor or create an installation that looks tight but does not preserve bracket geometry.
Complete technical approval before the harvest maintenance peak. Request a traceable sample, current photographs, configuration sheet, packing, quantity tiers, lead time and claim route. After approval, set receiving checks for clutch, voltage, ports, sleeves and labeling. Stock planning should reflect machine population and service capacity rather than an unsupported universal-fit claim.
Keep the approved sample record, incoming inspection photos, lot identity and application note so urgent field orders can be fulfilled without repeating identification work.
Elecdurauto can organize an aftermarket quotation for agricultural-parts importers, cotton-picker service networks and fleet operators. Provide the 4MZD-6 machine details, old compressor label and photos, clutch and port measurements, required quantity, delivery country and deadline. The supplier response can then address both fitment evidence and seasonal replenishment terms.
Include machine serial context when available, installed orientation, connector, foot sleeves, hose sizes, packaging request and whether a pre-season sample must arrive before the bulk order.
