Fitment note
Check the old filter, air cleaner housing label and parts book before ordering if the tractor has had an engine or intake-housing change.

Clean loose dust from the air cleaner housing before pulling the filter. Never run the tractor with the filter removed, even for a quick test.
Massey Ferguson 4840 Air Filter FAQs
Why should I compare the old Massey Ferguson 4840 filter before buying?
If the old filter is missing, use 7068311M91 plus the housing measurements as a two-step check. If either the seal or cover depth is wrong, do not run it.
Which Massey Ferguson 4840 air-filter parts should be changed together?
For a full parts check, separate the service element from the safety element: buy the outer/primary service element first, then buy the inner safety element only if it is dirty, damaged or due. Do not accidentally order 2127378K1 when you meant the safety filter, or 3703704M91 when you meant the outer filter.
Why does the full Massey Ferguson 4840 air-filter number matter?
Multiple numbers are useful only if each one is tied to the correct element position. Wrong element in the right brand is still wrong.
What symptoms point to air restriction on a Massey Ferguson 4840?
This is a higher-airflow class, so restriction matters fast. If it is working in dust, inspect before the 500-hour planning mark instead of waiting for visible power loss.
Why are there multiple air filter numbers for the Massey Ferguson 4840?
The presence of both outer and inner numbers means you should order carefully. A kit can be convenient, but only if it contains the correct service element and safety element.
