Essentially – don’t overdo it!  Have a break every 20 minutes.  Park the machine safely, get off it and have a walk around for a few minutes.  Even do some back exercises or stretches. Mowing for three hours or more at a time can lead to back strain so it’s important to have a regular break.

Grillo commercial machines such as CL9.22 and MD22 have an upgraded seat with armrests which is more comfortable for professional users who spend many hours mowing.  This is helpful but resting up and having a regular break is still very important and necessary to prevent back strain.
