If you have an older Toro 3250-D with DPAs that's doing this (photos) when the cutting units are lowered, check to see if you have the lift chains instead of the Hook-lift, offset (1.25") 110-2397 which come with the newer DPAs.
It took us over a year to figure this one out. It's not in any service bulletin but it should be. Just sharing this in case someone else is having this problem.
