    3 to 1 so approx 18 degrees that’s not that bad.
    Ventracs are engineered for 30 degree slopes (with their duallys on)
    2/3 of that 21 acre slope is going to be fine
    It’s the top 1/3 that’s sketchy.
    So you’ve got a 7 acre (or ten percent of the total area) issue.
    I’d say a walk behind mower would handle that without much trouble

    If you factor the walk behind in for 6 hours and the two WAMs for 6 hours
    That’s 18 hours
    At $70/hr you’re at $1260
    What kinda trimming/support work needs to get done on this place?
    Throw on another 50% if necessary and you’re in the 2 grand per cut ball park.
    That does come out to approx $26 per acre like mentioned earlier in the thread.

    This is a 25 degree slope for comparison
    The slope in question is about 18 degrees
    15 degrees is “normal” for a standard ZTR

    You’re trying to look at dollars per acre and saying cheap.
    But that’s not how jobs are done, they’re done by time.

    No one is going to do this work with a 21” mower.
    But the same equipment that would do this work is ill suited for a regular lawn.

    If you get a bat wing tractor at over 70 grand for one job
    Now you have to find other work for it that is scarce

    With some higher end ZTR WAMs you can still do this job AND look at larger “regular turf” where those machines would be applicable
    Anything with open multiple acres applies
    And with a super 104” you’re still using a normal mower trailer to transport.

    This brings your operating costs down.

    $2000 per cut gives a three man crew MORE than a day to do the work, but it shouldn’t need it
    If everyone finished in eight hours that’s over $80 an hour.
    If there isn’t much trim or support work and everyone finishes in 6 hours that’s over $100 an hour , in an industry where most struggle to get $60/hr?

    I might have done this a time or two.
    Don’t focus on dollars per acre, it’s not relevant.

    I assume the dam can be mowed up and down rather than across. Just about anything should be able to handle that 3:1 slope as long as it is not necessary to go across it and there is room to turn around at top and bottom. I see the job as quite appealing if it can be done without investing in equipment that will not be making money on other jobs.

    One thing I did not see was how many times it would be mowed during March - September. With it "hot and pretty dry last half of July and Aug" and the emphasis on weed control rather than fine appearance, you certainly are not looking at a weekly mowing, so thinking of pricing on a per-cut basis likely will not lead to the right result.

    I was misspoke. It's 25°+. They said it can be done with a tractor, but it needs to be the models that can be made to go wide. We plan on going wide and adding duals on the rear
    the 21 acres is pure slope
    Can't turn around at the bottom or top. has guard rail at the top and the riprap ditch on the bottom

    Figure 20-21 mows for the dam and 15 times for the remaining area

    they want it pretty decent. Last contractor is out due to not keeping it nice enough

    Oh, been laid up for a long while from my accident. Was spending too much time on here my wife was upset, she figured it wasn't for my well being. Plus had a heart attack last October. Besides that, life is a peach.....:laughing:

    How you doing?

    typical tractor/batwing mowing price is $25 per acre so that's what i'm going by.

    i don't do this type of mowing. i use a ztr and my price is around $50 per acre which would be double the price of tractor/batwing mowing.

    then again you would be stupid to mow 76 acres with ztr mowers. you would just blow their engines up in no time.

    going by the above rates $25 per acre is $2000 and $50 per acre is $4000.
