GENERAL OPERATION
Front Auxiliary Couplers
Weight Transfer The weight transfer system transfers weight from the attachment to the front wheels of the power unit when the front hitch is in float or assists in lifting the attachment. The operator can select different weight transfer rates using the weight transfer select lever. To set the weight transfer, raise the front hitch to its maximum height and move the weight transfer select lever to the desired position. Selecting the proper amount of weight to transfer de- pends on the attachment, the ground conditions, and operator preference. A lightweight attachment (e.g. KA160 power blower) will not operate in float with full weight transfer on. With full weight transfer on and mowing in the float position, the mower may not lower quickly enough when mowing through uneven terrain. The power unit speed or the weight transfer CAUTION Never shift range while under load, while moving, or while on a slope. Always ensure the shift lever is se- cured in the lock position at the end of the shift stroke. Always install the ball pin to prevent the shift lever from accidentally moving to the neutral position. Always use low range when operating on slopes of greater than 15 degrees. Low range is recommended for most pulling, pushing, and slow travel. High range is ideal for transport and light duty tasks. 1. Park the power unit on level ground and engage the parking brake. 2. Remove the ball pin and move the shift lever to the desired range position. ATTENTION rate must be reduced. High/Low Range Occasionally the engagement of the transaxle gears is prevented by misalignment. Moving the steering wheel slightly to the right or left will move the gears enough to complete the engagement. 3. Reinstall the ball pin to lock the shift lever in place.
CAUTION Dirt and other debris in the hydraulic system can cause damage to the system. Wipe the mating parts of the couplers clean before attaching the hoses to the hydraulic couplers. Install the dust plugs in the hydraulic couplers when not in use. If the attachment requires auxiliary hydraulics, couple the attachment hoses with the front auxiliary cou- plers. This is done by sliding the collar on the coupler rearward, inserting the male coupler of the attach- ment hose into the coupler, and then releasing the collar. If the collar will not snap forward on its own, pull it forward manually. The couplers that the hoses are attached to will affect the direction the secondary SDLA lever is moved to control the action of the attachment. Connect the hoses to the quick couplers so the colored indicators are paired together (red to red, etc.). The auxiliary couplers are controlled by moving the secondary SDLA lever to the left or right. NOTE: pressure build-up in the attachment hoses and the power unit couplers may occur, causing difficult installation of the hoses. If the hoses do not easily connect, try one or both of the following steps. 1. To release pressure from the power unit couplers, shut off the engine and move the secondary SDLA lever to the left and right to release pressure in the power unit’s hydraulic circuit. 2. To release pressure in the attachment hose, loosen the hose end and retighten after the pres- sure is released. WARNING Hydraulic fluid is under high pressure and can pen - etrate skin causing injury. Keep your hands, face, and body away from pinholes or nozzles that can eject hydraulic fluid under high pressure.
