how long does it take to mow 15 acres when you can only use a 42" mower do to tightness

According to Exmark's website, you can mow 1.35 acres per hour with a 42" mower going 4mph. So it could take you around 11 hours if you can only go 4mph. Now, if you can go 6mph, than it would take you between 7-8 hours. It all comes down to effeciency.

is there no possible way to extend a gate or is it just overall tight with trees or shrubs?

We never come close to the numbers on the efficiency charts. Thats our experience though and could just be that we are slow.

Two to three days, assuming the 42" is commercial grade.

I can cut about 2 acres an hr maybe a little more somtimes with my 52"
That is mostly wide open area. Is the space wide open with just a small access or what?
I would guess that with a 42 it would be about 1.25 acres per hr. Give us some more details so we can help you out.

the problem is it has a lot of trees and in front of most trees theres a stone with the name of the people that planted/donated it. the lawn area is broken up into many sections about 80 x 80 with about 20-30 trees to a spot. its like an old army base and lawns around the buildings spread out over 25-30 acres of land.

You have to put 2 days on it for 1 man so about 900.00.

I would say if it has alot of trees you can figure that your are at least going to take 2 full days if you are doing it solo. If it were me I would estimate 22 man hrs just to be safe. You should figure in gas and mower replacement at around $150 since you will be racking up the hours you have to make sure you figure that in your overhead for this paticular job.

I would stay around 1000 bucks with the bid unless its a job you can cut corners on weedeating. Some jobs that are larger like that we would scalp down to the dirt with the weedeater and section it off. Do a different section each time rather then the whole thing and it never looked bad.

sounds good, we are just getting into this and didnt know how long it would take. i think with a 42" deck on a walker with that forward design i can cut down on a lot of trimming.

sounds like you need to start at 0600 til nite fall & find one guy just to weedeat all day & give him $150 +/-. The weedeat man want be worth nothing at the end of the day, but if you do have to come back the next day, it could be only you just finishing up cutting.

here is a manufactures formula for how much you can cut in an hour. (width of cut x your speed)/120 = acres per hour

I think its for 120 seconds per minute after you do all the actual math conversion units.... but I'm probably wrong. I used to be good at math, but Im just getting older & dumber it seems.

I got the formula from a husqvarna book that said productivity was that formula (times 80% efficiency). So if I have a 61" cut width & a top speed of 10 mph the answer would be like this. (61x10)/120 = 5.1 acres per hr. But then you would need to multiply that times 80% to get a base average per hour (4.1 acres for that example). Meaning, who will cut there maximum width & speed all day long cause there will be some overlapping of the next pass.

If the property was flat with minimal obstructions, just mowing it should take you 8-9 hours nonstop mowing.
