Donaldson P821575 Air Filter, Primary

This fit my Briggs 39 HP Vanguard. It looks to be of equal quality of any OEM filters I’ve ever used. Metal outer protective screen, good filter pleating material and good soft rubber end caps. This same filter also happened fit my 49 HP Kubota Diesel tractor. So it seems to be a pretty common size for gas or diesel motors with 2-3 cylinders and 39-49 HP range that take a cylinder shaped air filter.

Hard to go wrong with a Donaldson filter. Work great on my zero turn mowers.

Arrived on time and fits.

OEM replacement for the 48” gravely mower with the Kawasaki motor.

You pay for what you get!

This is an exact fit for my 2016 Polaris Brutus HDPTO machine. Great price from amazon.com Dealerships want almost twice the price.

This is the correct filter for my 2018 Branson 3015R. Thanks for great service!

Perfect fit for my New Holland Boomer 40 T4B tractor.

Same as original I replaced

Fit perfectly in my Kubota L2501HST. Looks just like the original. I had heard that Donaldson makes these for Kubota.
