“I have had one other instance personally that I can remember where a snake got inside a lawn mower,” Hovenden told 9news.com.au.
“It does happen from time to time, it’s a good place for them to hide and feel safe so it’s definitely something to be aware of.”
Hovenden said eastern browns are “highly venomous”.
