Some thing i was wonder but cant find the answer to. I have a trailer that is 6.5'x12' inside with one foot sides. How many yards of mulch could it hold if it was loaded even with the top? Or heaped? Any idea how much this might weigh? This would be just the plain ole black mulch? Or what about if it had two foot sides? How much could it hold level and heaped, and what it might weigh? And if i am not mistaken, isnt mulch sold in yards? And one more question, how do you figure say cubic yards, or cubic feet?


Thanks!! chris

1 cu. yard of mulch = 27 cu. ft. Multiply your length by width by height to get total of cubic feet and then divide by 27 to get cu. yds.

In your case it's 6.5X 12 X 1 (height of sides) = 78 divided by 27 = 2.888 cu yds. If sides are 2 ft tall, double it. Mounded, sort of split the difference. Unless you have 2 - 3500 lb axles and very good (electric) brakes don't go for twice the amount: it'll push you all over the road.

6.5' x 12' x 1' ===>>> 78 cuft or 3 cubic yards with the 'heap'


Depending on the moisture content of the mulch (has it rained lately) I figure mulch to weight around 700 lbs per yard. A little more if its wet, say about 800 lbs per yard.

So at three yards I'd figure about 2200#.

I figure mine feet X feet X inches / 326 =
6.5' X 12' X 12" = 936 / 326 = 2.871 cubic yards

I have had 6 cy on my 6.5x12 with one foot sides......no problem.....make sure you have electric brakes on the trailer.....

I'd rather be selling you mulch than buying from you.

I would think you could get 3 yards. I have got 3-4 yards on my 12' flatbed, but it is 8' wide.

I don't understand the weight issue. Trailer brakes??? Give me a break! This is a light load, trailer brakes are nice but not necessary in this case. I hauled three pallets of sod today, one on the truck and two on my little 6x12 single axle trailer(no electric brakes). Slowing down was not an issue.

no way..........
full to the top would be 2.6 yd3
no way to triple that amount.

shredded bark went 875# a yrd average on a 5yd load.
went straight to the scale twice this year.

pretty sure all commercial trailers must have brakes anyway, so it dosn't matter.

875 pounds per yard??... maybe we have different mulch down here.

Wow, you guys must be getting screwed on your yard sizes. I have a 16' X 6.5' trailer with my 2' sides on they (the mulch company) squeezed 7yds on it heaped up and smashed down with the bobcat. And I had to allow alittle extra time to slow down even with the trailer brakes and a 3/4 ton truck.
The guy I worked for last year had alittle 12' trailer that we used as a back-up and the most we ever put on it was 3 yds smashed down and tarpped so that it didn't fall off the sides of the trailer.
Here is a crappy picture of 7yds that I had on my trailer!

Brakes are required on trailers over 3500 lbs. gross in the state of Connecticut.

A cubic yard: (L' x W' x D') / 27 = Cu. Yd.'s
How much your trailer can haul is determined more by your axle, springs and tires. I have a 5' x12' with 2' sides, single axle. I can haul 4cu.yds., but this will max out the trailer weight-wise. Obviously, taller sides would hold more
mulch, but the trailer couldn't hadle the weight. I would figure out how much
weight your trailer can carry safely, and use this number to determine how many yards to haul.

Heres how I figure mulch for a job.
Say the bed is 20' x 30' and you want to add 3" (inches) of mulch for a topcoat.
20x30x3=1800/27=66.666/12= 5.555 yds then I round up to the closest yd. So 6 yds total.

L'xW'xD"/27/12= total yards

Been using this method for 15 years.

When I first started. I had a 7 by 12 chilton trailer, with 2 foot sides. My supplier at the time, who was always VERY generous, would load a heavy 6 yards. I guess I did it too many times, 'cause I eventually broke 4 of the 6 lugs haulling a load. For those that think weight isnt an issue, even with mulch, and a trialer that size, it is.

2.6 x 3 = 7.8 cubic yards........I typed 6 cubic yards. That is a 1.8 cubic yard difference....

Let me correct myself, I was in a hurry......it has 20" sides.......

you short changed me about 1/3 of a yard for those measurements ---> 6.5ft x 12ft x 1ft = 78 cf or 2.88889 cubic yards.....

6.5ft x 12ft x 1.66ft (20 inches) = 129.48 cubic ft or 4.795 cubic yards loaded flat......mounded......6 cy easy......

Sorry for the miss statement early. My supplier has a bobcat with a very large bucket with "1 CU YARD" stenciled on it......

I have not personally measured it.....

I don't mean to sound ugly to you but your getting screwed!!!
I get 8 yards on my 12ft flat bed dump with 4ft sides round up and my supplier charges me $14.00 a yard for double ground. So my cost is $112.00
A load. How much are you paying for a load on your pickup.

Holy crap. Where do you live? I need to be sure to stay far away from you on the road!!!
3 pallets of sod about 12000 lbs added to truck and single axle trailer and all that weight stopping with only truck brakes. Youre asking for big troulbe.
Bragging about being unsafe (esp as unsafe as you just described) is like someone saying "man i was so drunk last night, i cant believe i drove home"...:nono: :nono: :nono:

We sell Bulk mulch, It needs to be one hell of a bucket on that bobcat, A full size "Backhoe" front loader bucket is more or less a yard, I'm not saying you're wrong, but do your self a favor and get a load of mulch some where else for a job and compare your load.
2 full buckets of a regular Bobcat is 1 yard.
We have been selling mulch for years and I buy it in 85 Yard loads and sell it as 83 to 87 yards, depending on what I use to load up customers...
I have just never seen a bucket that big on a Bobcat...

Happy holidays...

Um no your not. I can fit 3 yards of mulch in the back of my truck and it is piled up to bascially the roof line.
