I have an older (80s?) lawnboy mower. The air filter cover is
constantly coming off and the filter gets dragged out.

Is there a source for cheap "doors"/covers for it?
Is there a replacement air filter assembly that won't disassemble
under evergreens?

The new filter cover will have a hole in it that a clevis pin goes
through to keep low branches from removing it. You should go to a
Lawnboy dealer and buy the oem cover and pin. Cheap aftermarket covers
will not solve your problem.
