But its not much of an issue as this one is very steep, other slopes im on its slides slightly, whereby the old one wouldnt slide at all, but not enough to bother me so the handling on slopes is good considering its extra weight. But best to try for yourself off coarse.
I have used the 72" super z on the same ground as my 60", the 60" deck bounced around 10-15 times as opposed to only ever noticing 1 very slight bounce on the 72" over a decent sized rut. I put this down to the 72" deck being so much heavier. Also noticed that mower a little smoother, but it has a longer wheel base so hard to compare the two, plus was only for 2-3 mins use.
My 72 rides and operates I would say better than any ZTR made today, but yes, I have areas that if I hit them running very fast will make the deck jump, but it has a right to, the mower virtually goes airborne as fast as I mow.
I would think the 72 you tried would have jumped more, if weighing more...well that's according to the physics class I got from "Realslowww."
