I worked on a groundskeeping team for a small cemetery (in the US) as a summer job when I was in high school. Mostly, it was mowing grass, trimming weeds, cleaning lichen off stones (we got to use the power washer for that, which was always exciting), etc. There were typically only a few burials per month. We didn't do the burying; that had to be subcontracted out because it required special equipment and a lot of paperwork that us minimum wage schlubs couldn't be trusted to deal with. Where we were, the local regulations required that you couldn't just put a coffin into the ground, you had to put it in a concrete vault (probably something to do with the water table). So one of the companies that did that would show up with a truck and backhoe, cut out the sod, dig the hole loading most of the dirt into a truck but leaving a smallish pile there for the ceremony, lower the vault into place, set up the lowering mechanism, then clean up and clear out. After the ceremony, they'd come back, drop the vault lid into place, pack up the lowering mechanism, fill the dirt back in and replace the sod.
