Combines dusty cab

We blow the cab filter every day, when blowing the rest of the combine. Makes averything easier to service when it's cleaned off.

The place to check is where the wiring harness comes in to the cab behind the access panel ( right hand side as you sit in the seat),other areas are on top of the door evertime you open it,also if your 21 is fitted with the fold down rear window besides the manditory dump when you open it check for leaks around it.

We had trouble with the updated filter plugging after only a few hours of combining. As soon as the filter plugged, the cab would get dirtier because it would suck air and dirt in through other places. Our solution was to put new latches and some weatherstripping on the right hand cover where you access the concave eyebolts. Now our filter doesn't plug, and the cab stays cleaner. If you're filter isn't plugging up, I guess this isn't the answer you need. One place to check is where the throttle_hydro cables go through the rear of the cab.
