Work vehicle and control method for work vehicle

A controller controls the steering device so as to cause a vehicle body to turn toward the left when a left steering lever is operated without a right steering lever being operated. The controller controls the steering device so as to cause the vehicle body to turn toward the right when the right steering lever is operated without the left steering lever being operated. The controller reduces the rotation speed of the engine when both the left steering lever and the right steering lever are operated and both the operation amount of the left steering lever and the operation amount of the right steering lever are equal to or greater than a first threshold.

WHEEL CHOCK MOUNTING ASSEMBLY

A wheel chock mounting assembly includes a bracket and a stopper. The bracket has a retention member and is configured to be coupled to a surface of a machine. The bracket defines a receptacle to at least partially receive a wheel chock at a predefined location on the machine. The stopper has an engagement member. The stopper is configured to be mounted on the machine at a predefined distance from the bracket. The bracket and the stopper are structured and arranged to receive and constrain the wheel chock therebetween at the predefined location on the machine.
