Description

This 1991-built Komatsu PC50UU compact excavator with 11,500-pound operating weight has been professionally reconditioned and thoroughly serviced. It only has 3,350 hours, and the machine is in great running condition with minor cosmetic wear and tear as shown on our photos and demonstration video. This machine is equipped with a Komatsu 3D95S-W-1 diesel engine delivering 38.5 horsepower. The unit has been upgraded with new hydraulic thumb, new Panasonic starting battery, new seat & seat belt, new decals, and new paint. 

This Komatsu PC50UU has a highly-sought-after two-piece offset boom which is particularly useful for tight workspace applications with limited swing. If you are working in a tight alley, the boom can knuckle off to the right or left so that the machine can dig in line with one of the tracks up next to a structure. This PC50UU is also a zero-tail swing machine with its 1750-mm upper body, 2000-mm overall width, and a tail swing radius of 990 mm (3'3"). This machine also comes with a quick valve shifter that switches between SAE (a.k.a. CAT, backhoe) and Japanese (a.k.a. Komatsu) control patterns.
