PorkChop, I think that the YM1300D is the same tractor as the YM155D. And on the 155 about half way through the production life, the factory started to offer an optional better filter. That is the one that has the clear cleanable cyclone type pre-filter. It was a bolt-on kit for the 155, so maybe it would work on the 1300....though I think some of the 1300s got that filter too
