    Today I attended a pre bid metting for 18 LDS churchs. Serveral of these properties have a ball park or two, one has three ballparks plus the main landscaping around the buildings. Currently I have a ferris 36" and have the money to buy a stander 52" and or a 60" hustler super Z if I were to land this contract. My question is how much time should I expect per a acre(43,500sf) with the 52" and how much with the 60" on open turf areas. I currently only have experiance with the 36" so if you could share what I could expect with the 52" and or 60". :help: :)

    Go to www.dixiechooper.com They have a productivity calculator on the site. Put in deck size, speed, % of overlap and it gives you the results

    Not trying to rain on your parade, but I think you're going to need more than a 36" and a 60" to mow 18 church properties every week and stay on top of it.

    Am I missing something?

    Scag has a chart that I think is very practical and rather consevative in its estimate of mowing time with their machines.

    Even though most zero turns can go at 10 to 12 mph, and a few will get up to 15 mph, this is not a real world speed that can be maintained at all. Even if the machine can go this fast, you will be beat up so bad by the rough ride that you will find yourself averaging a much lower ground speed. So Scag bases their estimate on an average speed of only 6 mph.
    They reduce the total by 20% to allow for overlap, and other ineficiencies in the pathways around obstacles that occur in the real world.

    With a 52 inch mower deck, they estimate 20.2 acres in 8 hours or 2.53 acres an hour.

    with a 61 inch mower deck, they estimate 23.7 acres in 8 hours or 2.96 acres per hour.

    Round it off to 2.5 acres an hour with a 52 inch Z rider

    3 acres an hour with a 61 inch Z rider.

    You should have no trouble maintaining an average production goal that is set this conservatively.

    You might want to even consider a 72" with those ballparks and all.
