Husqvarna ZTH6125, ZTH5223 manual Mower Deck, Belt is automatically adjusted by a spring

DESIGN AND FUNCTION

Mower Deck

WARNING!

The engine must not be started if the operator’s floor plate or any of the guards for the mower deck’s belt is/are not securely in position.

The blades are driven by a V-belt from the engine crankshaft (1). The crankshaft has an electromagnetic clutch. This locks the deck pulley to the shaft when current is applied to the clutch (i.e. when the appropriate control panel switch is operated).

The belt is automatically adjusted by a spring

(2)operating on the pulley (3) attached to the top of the mower deck casing. Via vertical shafts, three other pulleys (4,5,7) each drive a separate blade. Two idler pulleys (6,8) serve as belt guides. The outermost pulleys are shielded by removable guards attached to the top of the mower deck casing. The operator’s floor plate acts as a guard preventing contact

with the belt and the other pulleys. 8011-580

Belt routing for the mower deck

WARNING!

The mower blades are extremely sharp. To prevent personal injury, wear protective gloves when handling the blades.

The blades do not require shear pins. Impact protection is provided by the blades skating on their shafts if they hit an immoveable object.

The discharge chute is on the right side of the mower deck. It is spring-loaded and can be raised.

For mulching, a BioClip kit is available as an accessory. The kit comprises guide plates and BioClip blades. It is fitted to the underside of the mower deck.

The mower deck is suspended to the bottom of the mower via two backward inclined struts and four adjustable chains.

Six anti-scalp rollers on the underside of the mower deck prevent the casing catching on the ground. Cutting height is set by a lever on the right of the operator. Inserting a pin through the holes in the deck height adjustment plates sets a limit to the downward movement of the lever.
