In operation when engage lever in up position the lower loop of belt drops onto rail/lip,this supports lower loop of belt,all slack in belt is now trasfered to top loop,this causes top loop of belt to move forward & disengage eng pulley,without cover installed top/bottom loop of belt keep dropping due to their own weight keeping belt engaged with eng pulley.The actual brake/parking brake is an internal hyd function of transaxle & regulated by the position of directional control valve(for/rev) or if drive belt disengaged thru a system of relief/check valves in pump manifold,this action now traps hyd fluid in pump & hydro motor locking rear wheel,this is why you have a freewheel/tow valve on pump manifold,opening this valve 1/4-1/2 turn releases trapped hyd fluid in pump/hyd motor & allowing rear wheels to turn so you can push tractor by hand or tow.
