Case L550 Front End Loader

The Case IH L550 non self leveling or mechanical self leveling front-end loader is designed for Case IH Farmall 65C, 75C tractors. The loader has double acting lift and bucket hydraulic cylinders.

The loader has a maximum lift height of 119.3" (3030 mm) at pin and clearance with bucket dumped of 86.6" (2200 mm). The lift capacity is 2838 lbs (1290 kg) to max height at pin, and breakout force (bucket on ground) is 4730 lbs (2150 kg).

The estimated cycle times are 2.9 seconds raising to maximum height, and 2.6 seconds to full bucket dump. The Case IH L550 loader can be equipped with a 72" (1830 mm) heavy-duty material bucket with a heaped capacity of 21.4 cu.ft (0.62 m3), or 84" (2130 mm) standard material bucket with a heaped capacity of 24.9 cu.ft (0.71 m3).
