Lawn rollers
KADAX K11287
A 50 cm steel roller weighing 8.3 kg empty and 48 kg filled with water — just under a kilo per centimetre.
The four numbers
50 cm working width. 32 cm drum. 40 litres of fill. 8.3 kg
empty.
That is more than two rollers on this shelf publish between them, and it is
enough to work out what actually matters.
What it weighs on the grass
Forty litres of water weighs forty kilograms.
8.3 + 40 = 48.3 kg, across 50 cm of width. That is 0.97 kg per
centimetre.
The point of that arithmetic is comparison. Three rollers on this shelf publish
enough to do it and they come out at 0.95, 0.97 and 1.00 kg/cm — effectively
the same machine. A fourth comes out at 1.50, half again as heavy.
This is the middle of the shelf, and the middle of the shelf is where most lawn
rolling is done.
Sand is denser than water. On this shelf the three products that publish both
give 72 kg against 46, 62 against 38, and 108 against 62 — ratios of 1.57,
1.63 and 1.74.
So a drum filled with sand is somewhere near one and a half to three quarters
again as heavy as the same drum filled with water. That is a different
machine, not an adjustment.
This listing publishes the litres and not a sand weight, so the heavy setting
here is unquantified.
Sand has one practical advantage water does not: it stays put. A water-filled
roller left outside over winter freezes and splits, so it has to be drained
every autumn and refilled every spring. A sand-filled one is simply heavy all
year, including when you want to move it.
The missing scraper
Not mentioned.
A scraper is a fixed blade that rides against the drum and peels off what
sticks. On dry ground it does nothing. On damp soil — which is most of the
conditions in which anyone rolls a lawn — it is the difference between a drum
and a rolling ball of clay.
Four listings on this shelf name one. This is not among them, and that is worth
knowing before rolling a freshly raked seedbed.
And the thing this whole shelf should say
The family next door sells tools for opening compacted soil. This one sells a
tool for compressing it.
Both are correct, for different jobs:
Roll to press seed into contact with the soil after sowing or overseeding;
to settle new turf; to flatten a surface lifted by frost or by mole activity,
after you have levelled it by hand.
Do not roll as routine lawn care, and do not roll wet clay at all. A heavy
drum over a saturated clay drives the air out of the top few centimetres, and
the result is exactly what an aerator exists to undo.
