Full cab or just a roof that mounts to the ROPS?
Where does your exhaust pipe exit the tractor? Straight up out of the hood or low to the side or front?
Is it a rattling noise? If so, can you tell from which direction?
Does it happen at all RPM's?
Just the roof mounts to the rops.They say alot of noise comes up the rops from the hydo unit some fill the rops tube with expanding foam.I might try that.
No chance it came with the tractor.I took it off because no way to remove quickly for trailering tractor.I modified it so it came off easy but the noise was awful.
