I get 3,000 pounds how about you?

Laminarman · May 12, 2004

I have a chance to get a lawn roller cheap that measures 24 x 48" long. Filling it with water I calculate it weighs (water alone) about 3,000 pounds. Now I need to figure out how to hook it on my drawbar. It's one made for a garden tractor.

I think it is more like 750 lbs...but I did the math in my head so I would not count on it... /forums/images/graemlins/blush.gif

Chance are I might be close though. I can't imagine a garden tractor pulling a 3,000 lb roller... /forums/images/graemlins/smile.gif

Sounds like you're off a little. Using Pi* R^2*Length, I get about 94 gallons. Rough number of 8 pounds/gallon gives about 752 pounds.

( Rough number of 8 pounds/gallon )

Clean water weighs in at 8.33 lbs / gal

Sewage weighs eight pounds and a turd.

Thanks guys. I guess that serves me right for doing this on my morning thinking post with pencil and pad. Sorry about that. Now on to the question: can I rig this puppy and will it roll disced dirt flat and firm prior to seeding (clover and/or grass depending on which part of my property I'm on)? I've been told to get a cultipacker, but too expensive for the limited use. This costs $75 used, and my water is pretty free. Only drawback is it's only 4' wide on a 40hp tractor.

Just saw the other post here marked "roller" that addresses my issue quite well. Sorry for the redundancy.

( Only drawback is it's only 4' wide on a 40hp tractor. )
Wrong tool for the job. Even at 750#, it will probably bounce. When encountering a 10# rock, it will surely dent - maybe even rupture. At that point $75 will look cheap.

Ever think about rentals?

That's funny, i actually laughed out loud.
It is good to know I am not gowing out of the "potty humor" phase /forums/images/graemlins/grin.gif

How about two fifty five gallon drums welded togheter and filled with concrete?

Concrete is about 2.3 gm/cm^3.
1 gallon is 3785.412 cm^3.

So 110 gallons is 416395.32 cm^3.

So this thing is 957709.236 gm or about
2107 lbs.

This is excluding the weight of the drums and the metal that forms the hitch.
This is plenty heavy enough for me. In fact I recently bent the hitch frame since it was the weakest of the three parts; my tractor, the conrete filled drums, and the hitch.

If you really have a 3K lb roller by very careful. I pull my 2K roller with a 70hp 4wd tractor or a Diesel F250. Even then the steep hills make me a little nervous. What happens when the hitch breaks and that 3K lbs runs wild? Maybe not a problem for you. But my hitch is home made, by previous owner, and it was not overly engineered.

On edit:
A roller 48"x24" is about 94 gallons or 355838.629381 cm^3.
Density of water is 1 gm / cm^3
Therefore your roller should be 355839 gm
or 784.47 lbs.
