2004 HP 23/52 with ultravac ... mowing at deck height of 3.5" and a significant amount of leaves are blowing out of the front of the deck. A 2nd pass usually sucks up the stragglers, but it's a waste of time. I asked my local dealer about the blow-out baffle, but he recommends lowering the deck to 2.5-3". I'll give it a try, but ... 1. Will the blow-out baffle kit improve the performance of the ultravac? 2. Can the blow-out baffle be used year-round with or without the ultravac?
