Attaching to the KX080

ATTACHING TO THE EXCAVATOR 5

ATTENTION

The K4080 brush mower is designed specifically for the Kubota KX080 excavator and should not be used on any other machine. Make sure the person who is attach- ing this brush mower has knowledge of attaching regular buckets and can do so in a safe manner. The method used most often for attaching this brush mower is the “curl-in” method.

Note: Remember to allow at least 3-5 minutes for the excavator to warm-up before using with any oil-operated functions or attachments.

2	• Move the KX080 into position behind the brush
	mower. Keep in mind that the “back” of the

mower is the end with the hydraulic motor.

•Once the power unit is in position, lower the ex- cavator arm into position, inserting the rear por- tion of the mount into the Quick-Attach (1) first and then “curling” the front portion down into place. Insert factory pin (2) to keep brush mower locked in place. Refer to photo on left.

•Extend the main excavator dipper to its full length in front of the excavator and set mower down with the skid shoes firmly on level ground. This will allow for easy access to the (3) flat-face couplers. Never stand on attachment to reach couplers. Turn off the excavator and bleed down pressure on both high and low flow hydraulic circuits. See Kubota KX080 Operators Manual.

•Couple the hoses. The female end on the shredder is pressure in (left side) and the male end is return (right side). These hoses should be coupled to the high-flow circuit (26.4 GPM) oper- ated by the right-hand joystick in the excavator. Then enable hydraulic breaker mode on the ex- cavator, allowing for zero pressure return, (4) by turning the valve located near the hydraulic reser- voir to the return to tank position. This step is vital and if not followed will result in damage to the hydraulic motor. Also, the high flow circuit is most often the closest to the cab of the excavator as shown in the second photo.

•If equipped with a thumb, plumb to the low- flow circuit (17 GPM), which is operated by the left-hand joystick on the excavator.
