The death of a woman involving a ride-on lawnmower is being treated as suspicious.
Police say they are still unsure what happened to the 49-year-old mother-of-three at an Upper Lockyer property west of Brisbane.
Detective Superintendent George Marchesini said the woman was found at the property with critical injuries about 3.45am on Tuesday. She died at the scene.
Her husband allegedly told police he found her and called triple zero after there was an incident with a ride-on mower.
Supt Marchesini said the death had been deemed suspicious because they were still unsure of what had occurred.
"There's a number of things that we need to understand better, to understand what the cause is and how this actually happened," he told reporters on Friday.
Supt Marchesini said the husband was assisting police with the investigation.
He said there were no domestic violence orders in place between the pair, but police had attended the property in July last year "where action was taken".
The woman was last seen alive on Monday afternoon.
"This is a tragic incident," Supt Marchesini said.
"It's an incident where our hearts do go out to the family, in particular the woman's three children, the community, her workplace and also first responders that go to these types of jobs."
Anyone with information is urged to contact police.
"If they have knowledge of the woman, they've got knowledge of the family ... we want to hear from them in terms of what they do know," Supt Marchesini said.
