7520 air filter

kRM1976 · May 6, 2015

We have 7520 4x4 tractor that the air filter light comes on and stays on. I put a new filter in and 2 hrs later the light is on, blow it out and it isn't dirty, its like it isn't getting enough air. Any one else have this problem, or suggestions? Thanks

Has the tractor been washed recently? The sensor can get water inside and short out. Deere is very proud of that sensor.

I would unplug it, and keep an eye on the filter as you go...they didn't work well from the start...

I pulled the filter and the light went out. It's like it's not getting enough air, but I can't figure out why.

Have you ever replaced the secondary air filter? Have you inspected pre-cleaner for blockage?

It sender is too sensitive,, if the filters are clean that's about as good as it gets..There is always a bit of suction at the filter and when you remove the filter there is less so at that point the sender is satisfied..

Have you checked the cyclonic pre-cleaner to see if the plastic tubes have self-destructed inside or are clogged?
