Hi Jarryd,
The Shindaiwa 22T is a 21.1cc lightweight domestic trimmer that would be OK if you were only using it on one or two lawns a day...It would not last very long in commercial use; and, is not designed for that application. wink

The Shindaiwa T260X is a much better option and is placed between the domestic and professional models.
Most contractors use a 24 to 25 cc engine which gives long life (carefully maintained) and has the extra grunt when required. wink
Hoping this answers your question. grin
