Brushogging

[Jdhager87]

Approximately how long to brushhog 35 acres with 65hp tractor and 7’ cutter? Guesstimate.

Other than a SWAG, IMO there are way to many variables to consider.

Flat, hilly, smooth vs rough, propery shape, contiguous, obstructions, type of material to be cut, tractors turning radius, etc.

Somewhere around 10 hours, at 4mph. That's assuming full 7 foot cut every pass, no doubling back, no over lap, no BSing around. Now, if you can pull off 4.5 mpg average, it will be a bit faster.

I think 4mph is a pretty good number for a field, but if there are obstacles, heavier brush, ect, it could very well be 3 mph, or 14 hours.

4mph would be too fast for me. I do about 35 in 3 6 hour days. I have 75Hp with 8’ cutter. Impossible to not have overlap and turns etc. This is brush cutting not finish mowing.

Kinda what I was thinkin. 12 -15 hrs. Just gitting other opinions. Thanks.

At 4 mph, and a full 7 ft cut with a field 7 ft wide by 41.26 miles long, it would take 10.34 hours.

One thing that we can't speak to, is your unproductive time. That's turning, lining up your passes, stopping to 'water the grass', ect; and it adds up more than people think, especially on anything odd shaped.

I would throw a guess out there, that maybe your 85% efficient; so if you are bidding this for someone else; I would use the 14.38 hours at 85% efficient; I get 16.91 hours total job.

If you are mowing a unknow field, you may want to double the hours mentioned above in order to have time to react to possible hidden objects. Ken Sweet

 

[big bubba]

is this for hire or your own? i'm always skeptical of unknown fields, esp hardware w/loaded rear tires.

That math is pretty simple. It also ignores everything that doesn‘t involve mowing in a straight line.

4mph brush hogging? That's cooking.

I think it's a good estimator, but yes the shape, condition, and material in the field have a huge influence. As does the skill of the operator.

I think there's a lot of optimistic numbers being pushed so far, I mow a lot of hay and with a 9' cutter mowing flat mostly square fields I'm close to the numbers people are putting up.

 

[EddieWalker]

3 mph is my top speed for bushhogging on my land, and that's in the open areas. If I go faster, I'm bouncing all over the place and not comfortable with how quickly things come up that I need to avoid or bounce through. I go a lot slower in the tricky areas.

I'm on a 70 HP tractor with a 12 foot batwing. I own 68 acres, but I only mow areas of it at a time. I've never tried to mow more then 10 acres in a day, I have too many other chores and projects that need to be done. Mowing is how I finish off a day when I have a few hours to do something, but I'm too tired to do anything besides sit in an air conditioned cab.

 

[JJT]

12-35 hours, spread over 4-10 days.

 

[Sawyer Rob]

I'm betting you will AVERAGE about 2 acres an hour.

Agreed. Very optimistic indeed. For me it would be 3 full days and at the end my hour meter would have 18-20 more hours on it. I cut at 2.3 MPH top speed and have to slow down at times. Anything faster is not a good cut and leaves brush clumped and pushed over. My current blades have about 200 acres and So they are sharp…

 

[paulsharvey]

So, part of this depends on the material being cut, and also the desired cut quality. If you want to really cut it, or just cut/knock it all down,

 

[Yander]

No one asked how tall the field is and that is the one variable that is easily figured in. So, how tall is the material you are cutting. There is a big difference in cutting a field that is 2-3 feet high and one that is 4-5 feet high. Mph will vary greatly.

Also, assuming we are just talking weeds and not bramble, or sapplings?
