Can a 25hp Super Z handle Doulbes

It sounds like your having a balancing problem. Do you balance your blades? Even a screwdriver will work in a pinch.

The decrease in HP is normal. It shouldn't be significant, but slight.

And yes you will have twice as much vacuum.

i did the exact same setup, lot more vaccum,but i did not notice any vibration.as for the hp ? ,i think the 25 is plenty capable, but i could not run as fast as normal,but the cut was excellent. i guess just use your own judgement

ive ran em on my 27 kohler super z, nice results but you will sacrifice some power to do so. balanced blades and making sure they are in a perfect + pattern is crucial.

You don't "need" doubles on a Super Z.

Hey why do you need doubles? Why buy a mower if it needs doubles for a good cut.

My Hustler Super mini Z cuts perfect. I have demoed a Exmark ztr before and it cut perfect.

Can someone enlighten me what ztr needs doubles to have a good cut or is it needed more in the spring when grass is wet
and growing fast?

Honestly, I am not trying to be a wise guy but what am I missing?

Actually,....I only run doubles in the Spring and in the Fall. I SURE don't run Gators for cutting grass! This defeats the purpose, entirely. In the Spring, when we have heavy growth and it is wetter conditions, I run Highlifts and low-lift mulching blades on top. In the Fall, it is highlifts and Gators on top. The Gators work great for leaves, but while they DO mulch grass up a bit more, they also have a tendency to make wet grass coagulate into little balls of wet grass. When it dries, it often leaves an undesirable result on top. I just don't care for the results. As far as mid summer mowing, there is no need for me to run doubles, - except perhaps sometimes with the thick grass that we are cutting on our irrigated properties. (Our fert. program isn't doing us any favors in the mowing department - it has become so thick).
