Z mower diesel vs. gas comparison results

OliverGuy · Sep 3, 2014

This is not real scientific, but if you would like to know the results here it goes: Exmark's with Kubota's or a Toro with a Diahatsu, all 72 inch use .7 gal per hour. Toro and exmark's with Kawasaki and kohlers on 60 inch decks use 1.2 gal per hour. Have a couple gas 72's that I will calculate out next week. The basic chassis on all these mowers are the same, and they get commercial use every day. When I did this last time, kohler fuel injected engines on 60 inch decks used less that 1 gal per hour. I don't know if the payback is there if you buy a new diesel (very expensive), I have bought my diesels used with less than a 1000 hours on them to try. Surprisingly the Diahatsu has been very trouble free by the way. Got caught up in the excitement of an auction one day and thought I was buying a Kubota engine, oops.

I have had 25hp gas on 60in decks and now run 25hp diesels on 60in decks. Gas burns twice as much as the diesels.
According to some JD manuals I have read, that is just about what the factory claims too.

what I want to know is how efficient are the things when working, I get that there way better built than the box store riding lawnmowers, and there more maneuverable, and much faster but,thats for a nice smooth lawn, how are they in not smooth lawns? around here, they throw out grass seed on top of natural mountain grasses, when cutting some of these places will bounce ya off a full grown tractor, and a riding mower can actually get high centered on a clump or too, there not all that bad of course, but most are not nice smooth well prepared lawns like found in eastern cities, are the z turns any advantage or would they be just as slow as a rider?

thanks, I have been looking at them but couldn't find out if one could still use the advantages a z turn offers on rough ground or if the ground would make them as slow as a lawn tractor, on my place the ground is so rough due to drought that a full size tractor is the only way to stay in the seat, were getting some rain now, but its been a year coming, what we need is a z turn with large wheels
