For those of you that keep track and have a general idea, post your average "mowing only" productivity and equipment.

Here is a link to Exmarks prductivity charts for groundspeed and various deck sizes ... assuming that if you have the same width deck and are travelling at "X" MPH, it really shouldn't make a difference between the various different manufacturers, the productivity should be the about the same.

Even at the 80% productivity, I have found that with my 48" gear, I cant hit the productivity marks exmark gives. I have found my rates to be 80-90% of exmarks 80% figures.

I agree! I think even the 80% numbers look too high as well.

It took a little doing but I figured out the formula they use for 100% efficiency...

Width of cut x mph / 99 = 100% efficiency acres per hour

80% accuracy is width cut (in inches) x mph / 120 = 80% effeciency. 100% is just going at the exact speed mentioned, in a straight line for an hour. No turning at all or slowing for extra thick/wet grass, etc. Jason, 80% of 80% is 64% I think. Should be...theoretically, haven't tried it, that would be:
inches of cut x mph / 140 = 64% actual effeciency??? think

OK I just got out the calculator, here we go:
48" deck x 5mph / 100 = 2.4 acre/hr. @ 100% effeciency.
48" deck x 5mph / 120 = 2 acre/hr. @ 80% effeciency
48" deck x 5mph / 140 = 1.7 acre/hr. @ 64% effeciency

Then I figured 80% of 80% and it was indeed 64%, so the above is correct. Remember, 1 acre is 43,560 sq. ft. There you have it.

Good reply, Eric...i always felt all the productivity charts put out by the manufacturers were overrated.

Like you mentioned, they don't take into account stops, turns, high/wet grass, terrain, etc.

7. ### KLMlawnLawnSite Senior Memberfrom Long Island, NYMessages: 443

Well that was the point of the 80% chart, but I have to agree ... that is usually very hard to achieve unless you are on very wide and open acres.

8. ### Envy Lawn ServiceLawnSite Fanaticfrom North CarolinaMessages: 11,062

Well, this thread has been on here for a while and frankly...

I'M DISAPPOINTED....

With all this jibber jabber on here about..."oh my mower goes 10 mph!!!!"....????

Now no one wants to talk productivity??? I figured people would just be jumping to brag about how much they can cut an hour.

I have those MFG's productivity charts. They are just formulas. Formulas don't mean jack out in the field. I'm looking for "real life" averages.

Can anyone else help me out here?

I think I average roughly 1000sf per minute with 60" Lazer.
