A mortar buggy with stake bed assembly provides a removable flat heavy duty base platform and a rear panel that can be fitted onto the chassis of an existing mortar buggy or similar conveyance in place of a hopper. The stake bed assembly provides removable front and side panels made of solid steel or similar alloy that can be configured to attach vertically in a hopper configuration or horizontally in an extended flat bed configuration, to provide additional loading surface for long or large items. The stake bed assembly also provides for a removable front tailgate with the ability to hinge at both its top and bottom so that the front tailgate can swing either up or down.

A rotary power trowel machine for finishing concrete surfaces and more particularly to a quick adjustment mechanism for the pitch of the blades. The quick adjustment mechanism includes a control lever mounted on the operating handle of the trowel in a position to be easily grasped and operated by a trowel operator. The control lever changes the blade pitch through a mechanical advantage linkage which reduces the force applied to the control lever to adjust the blade pitch. The control lever includes a locking mechanism to lock the control handle and linkage in selected positions to lock the blades at a desired pitch angle. The locking mechanism includes a semicircular guide mounted on the trowel operating handle and extending through openings in the control lever. A locking device on the control lever lockingly engages the guide and is selectively locked and released from an upper end of the control lever.
