    I have bid 2 large commercial jobs that consist of about 60 acres of mowing. The thing is not much of it is really wide open mowing so a wide area mower is out of the question. I already have 2 60" Toro zero turn mowers, I was wondering how much time I would be able to save if I were to go buy 2 72" zero turns. I have to keep the 2 60"s because they are setup to my bagging of large properties, so I would be looking at purchasing 2 more mowers. This does not concern me because there are both 3 year bids.

    If the 72s will fit I believe that it would be a good idea.
    Just be sure that there is not a problem with scalping.

    Here's a little math. A 72" is 20% bigger than a 60". Let's say you can cut 5 acres in one hour w/ a 60", you should be able to cut 6 acres in that same hour w/ a 72".

    You also need to factor in speed to the above statement/equation. I switched from a 60" Lazer to a 72" Dixie Chopper. The Chopper is 33% faster than my Lazer was. I believe I was almost 25% more efficient last season with the Dixie.

    I had an Exmark 72" ztr that I used on a golf course we owned. It was very impressive. Great quality of cut and fabulous speed.

    I actually sold a 72" toro groundmaster and replaced it with a 52 Scag Wildcat. I already had a 60 Tiger Cub the toro 72 was limited in its acess to areas and the poor cut due to scalping on even the smallest of hills.

    I would really look at your entire job mix to see if you can utilize the larger mower at other locations. If not Buy two more 60's and option them out, comfy seats, cup holders ect, you wont have as many different size blades laying around either and your operators will be more comfortable, and if you need to you could always switch your baggers over to the new machines if you had a break down.

    I had considered another 60" or 2 that way I could switch my bagging setup to one if need be. The only thing that makes me wonder is exactly how much time I would save with the 72" mowers.

    Speed woud be same so you only gain in effiency would be the extra 12 or so inches you'd be cutting , which would be a savings about about 20% or so....

    But I like the flexibility of having the same machines and not needing to maintain as big of a parts inventory......Blades and Such....If you can';t use the machines on any other properties then at the end of three years they will have low hours at least....

    Go to www.dixiechopper.com, under why Dixie you will see Productivity. There is a calculator that will let you choose Deck size ,speed, hours and overlap.

    Another thing you guys are missing out on is the fact that the 72" will eliminate an entire pass of the 60" every 5 passes, and not only that, you eliminate the time it takes to turn around as well.
