A lawn mower comprising a deck mounted on at least one castor wheel assembly characterized in that there is provided a locking mechanism capable of holding the at least one castor wheel assembly in the direction it is travelling when the locking mechanism is operated. The locking mechanism comprises a braking surface and a braking element such as a brake band or pad which is movable between a first, or disengaged position where the braking surface is rotatable relative to the braking element to allow the castor wheel assembly to swivel about a substantially vertical axis, and a second, or engaged position where the braking element engages and holds the braking surface. The locking mechanism is manually operable by an operator standing behind the lawn mower and holding the handle thereof.

[ What is claimed is:] [1.]1. A lawn mower comprising:a deck mounted on at least one castor wheel assembly;a locking mechanism capable of holding at least one castor wheel assembly in a plurality of different positions relative to a direction of travel of the mower; andan actuating system for enabling an operator to engage and disengage said locking mechanism;wherein the locking mechanism further includes:a first part mounted on the castor wheel assembly;a second part mounted on the deck;a braking surface formed on one of said first and second parts;a braking element mounted on the other one of said first and second parts, the braking element being movable between a first position where the braking surface is rotatable relative to the braking element to allow the castor wheel assembly to swivel about a substantially vertical axis and a second position where the braking element engages the braking surface to hold the castor wheel assembly stationary relative to said direction of travel; andwherein the braking element comprises a band that extends around at least one part of the braking surface.
