    I am starting up, but I have a number of friends and family that would like me to mow their land. I personally just moved onto a 5 acre lot, so anything I buy for my business I will also use on my land. Most of my accounts are over 4 acres and flat. I am looking at a Super Z, say maybe 60 inch Honda engine. Any thoughts about this choice? My number one concern is speed, and these seem to be the top of the line in that area. Thoughts on accessories?
    Thanks

    If your # 1 concern is speed, then you have come to the right place.
    I would suggest you look at the Super Z series and get as much hp as you can / afford.
    More hp = less slowing down in taller / rougher conditions.

    If you look in the specs I think you'll find that the 24hp Honda is a little lacking in the torque department when compared to the bigger Kohler or the LC Kawi's. Go the most HP you can afford! I've got a 27 Kohler on a 52" Super Z and in thick lush gowth of the rainy season I sometimes wish I had more.

    PJ, I've spoken to Mick at JD and he said the 27hp Koehler would be a better choice for me. However, when I look at the specs, I see a big drop in torque from the 24hp Honda (37.5ft lbs) to the 27hp Koehler (32.7ft lbs). Mick seemed to think that this was a misprint in the product specs. Is this true? And if it isn't, why such a big difference in torque?

    The 28 efi is a step above the 27 in the Kohler engines and you probably want mind the 25 to 30% fuel economy savings with the efi. I have had two 27's and now have a new 28 efi with the XR-7 deck, the efi actually feels faster, and with no throttle lag on the efi it definitely has more usable horse power.

    I have a 28/60 and want more HP. Cutting thick bermuda on a hill sucks the HP very quickly.

    I love the machine but would just like more HP for my area. A small diesel or 30+efi would be better for me.

    Now if your cutting on level ground and cool type grass, a 28efi would probably be ok. But as we keep saying, you never hear anyone want less HP!
