Two Ryobi pressure washer models have been recalled due to projectile hazard and risk of serious injury, according to the U.S. Consumer Product Safety Commission.

According to a notice on the U.S. Consumer Product Safety Commission (CPSC) website, about 39,000 John Deere ZTrak Zero Turn Mowers with Kawasaki Engines (in addition, about 2,500 in Canada) have been recalled because the voltage regulator inside the mower’s engine can fail while in use or while the product is being stored.

The recall includes 23,400 models of its 2013, 2014 and 2015 RTV400 and RTV500 series gas-powered utility vehicles. Kubota has received nine reports of shafts breaking.
