Can anyone tell me how to calculate the compression load from a lawn roller? I want to roll my lawn to smooth out some ruts. The biggest roller that doesn't cost an arm and a leg is a roller that is 48 inches wide and 24 inches in diameter, weighs 910 lbs when full of water. I have a TC40D with turf tires. They are not loaded. The width of the roller should cover the distance between my tires. The question: Is this weight roughly equivialent to the weight displaced by the tires of my tractor? The specs on the tractor show 3300 lbs. Turf tires are 27x8.5-15 in front and 44x18-20 in the rear. I know there is some formula that should work here based on the weight vs Width vs diameter but it has been a long time since.....

To do this we need to know how big your foot print is on the ground which varies with air pressure. Chances are you are about equal comparing the roller. ....

I thought I posted a reply yesterday but do not see it. Here goes again.
What would be your guess as to the front to rear footprint of the roller? I would guess 1 inch, maybe 2. If it is one inch times 48 inches wide, that is 48/144 which is 1/3 of a square foot. So 900 lbs divided by .33 sq ft is 2700 psf, or lbs per sq ft. Your tractor tires might amount to 4 or 5 sq ft of footprint. 3300 divided by 5 is 660 psf. I think no matter what the exact measurements are, your roller will put more psf than the tractor.
