We'll see how it works on pine cones and pine needles the bane of my existence. I have 11 large fir trees and this stuff rains down at times.
I have the X 758 and the three bag Power Flow it works great on pine needles . Only problem the bags fill very fast .
The main reason I upgraded from a 100 series to a x749 was for raking pine needles on customer lawns. Bought the pine straw rake, 3pt hitch kit has basically solved the pine needle raking problem. Works great and allows me to get in most areas to rake under the pine trees.
About a year after getting the mower I added the MC 519 cart. The 19 bushel capacity is much less trouble for large lawns and the blower works well. I usually mow without it and use it once or twice a year for clean up purposes. My preference is to mulch and leave the nutrients in place for the most part.
