    This summer I bought a Z710A with a 54" deck as I was trying to keep weight to a minimum. I had the optional rear gauge wheels installed on the deck. It has worked very well for me.

    mine used oil until 100hrs or so then it seemed to stop...it's been holding steady for 25hrs or so now.

    to the OP i have 26hp with 54" and it does pretty well...it will bog down in really tall/thick or wet grass but most any mower will do that lol....any grass under a foot tall it won't bog down unless it's really thick or wet.

    i was told my new mower shipped from the factory yesterday. i am hoping to see it by saturday. thanks to all who posted. the biggest thing i hear on the 910 is the power issue. i think 22h.p. should be fine,as i won't use it in any commercial applications, just my 1.5 acre home place.

    have the 920,54 PRO deck. bought new Sept. 2010 only problem was at about 200 hours it popped the deck belt. dealer had a service bulletin to add extra belt guides and new belt. if it happens again it says to replace PTO clutch,belt and both wheel motors. other than that it has been great. 360 hours as of today.

    The oil level in my 925a has remained the same for some time now. Looks like it will be ok. Season is winding down though, I'll probably just wait till spring and keep an eye on it.

    I just bought a 910 with a 54" deck to replace my 1700hr exmark LazerZ with a 52" mulching. When I went to pick it up Saturday, it had a cracked fly-wheel, so I have to wait till Tuesday. I am looking to add a mulch kit and have been doing a lot of reading about how to change the jets out in the carb to get extra power from the engine, but have not decided to do that yet. The power issue was a small concern but I can live with it.

    It isn't the jets you'll need to change. It's the throttle plate assembly. You will want to do it to run a mulcher or bagger with that engine/machine and deck size. Was this a used unit? Just curious about the flywheel being cracked.

    Why got through the hassle of changing throttle plates and what not. Why not just get the z920 or what ever size a person would need in any scenario. They can't be much higher. Last spring I was quoted 7750 for a z920 with a 54" and take 500 off that if o took 2.

    since the 910 and 920 share the exact same engine (other than the throttle plate), a lot of guys here have bought the 910 for a grand - 1500 less than the 920, and for $35 worth of parts and an hour or a bit more of their time have swapped plates and ended up with the 920 powerwise.
    One guy here a while back posted that he bought a new 925 and swapped in the throttle plate from a 930. Why he didn't go with the plate from a 950 is beyond me, but he said he had no interest in swapping it out again for another couple ponies.
