I've had my Big Yella for a few years now, I very much prefer it to a 175 or "swing machine"as I've always called them.
After about 30 years on the "swinger" my back was a shocking mess.
Since getting Big Yella, and no more "swinging", I've virtually no more back problems.
Regarding vibration, with Big Yella I have no problem.
I also have an Sprayborg, whilst this machine is slightly quieter than Big Yella, it does vibrate that little bit to make it annoying.
With education from many of you here and elsewhere, I've learned where I can get the best clean from each machine.
One main feature of Big Yella for me is the shower feed of solution as opposed to the spray jets on other machines.
With the shower feed there is noticeably less airborne solution to ingest,
and working in confined spaces, this can really get to the operator at times when one is using the spraying system.
As my main focus is now on commercial, Big Yella is the one most often rolled down the ramps, although in some cases I will revert to the Hos.
When S.W.M.B.O. comes on commercial work, we will use both to cut the time down dramatically.
