The rate of spread of chippings box has a removable acrylic lid which is graduated with an 800mm rule.

After the chippings spreader has dispensed chippings over the open box, the lid is replaced and the whole box
up-ended to read off the volume of aggregate collected. Every 10mm on the scale = 0.5 litres per square metre volume of aggregate dispensed by the spreader.

The box is also fitted with adjustable legs to raise it from the ground if necessary.
