Will change fuel filter and hydraulic filter this afternoon to see if that works but stumped on what else to do. It’s hydrostatic so could it also be hydraulic issue when turning blades on and trying to turn? It’s a reel mower and when I try to turn its sounding like it’s dying down. When I put blades on and try to go forward it dies down. Not sure if it’s fuel or hydraulic. Yanmar engine. TIA

Never heard of a diesel lawnmower.

Fuel cap will start to get clogged on diesels, and it puts a vacuum on the tank and prevents diesel flowing into the fuel pump at high RPM, and you get a starvation issue. a $9 fuel cap will fix that. If that makes no changes, of course make sure the air filter is clean, then inspect fuel feed from tank to filter.
