I'll guess that a larger deck will tend to load up more quickly..not too positive on that one. Also the obvious don't mow wet or damp grass... A couple of other ideas about mower deck anti-sticking and longevity; Rhino lining, Arma-coating, or whatever local pick-up spray bed liner company is in your area will spray your deck for cheap if they are doing a batch and your deck is clean and ready to be sprayed, i.e., no prep needed. Be sure you've got any threaded holes that you're going to use plugged with a bolt or taped off. Eastwood company sells a spray undercoating used for car restoration for about $11.00/can that worked for me as well. One can covers about 7 sq. ft.
