Massey Ferguson 50HX Backhoe Loader
The
Massey Ferguson 50HX backhoe loader was manufactured between 1987 and 1997. The
Massey Ferguson 50HX is fitted with a Perkins A4.248 four-stroke 4-cylinder
liquid-cooled diesel engine rated at 77 hp (57.5 kW), and 4x4 power shuttle
transmission with torque converter.
The maximum travel speed (forward or reverse): 17.6 mph (28.3 kph). The
open center hydraulic system used a piston pump with fluid flow rate of
29.5 gal/min (111.6 l/min). The 2WD models are equipped with 11Lx16
front tires and 16.9x28 rear tires.
The 14.0x17.5 front tires and 19.5Lx24 rear tires are used for 4WD
models. The wheelbase is 85.9" (2180 mm) for models with 2-wheel drive,
or 85.7" (2170 mm) for models with 4-wheel drive.
The loader has a maximum lift height of 165.5" (4200 mm) at pin and
bucket dump clearance of 108" (2740 mm). The lift capacity is 6017 lbs
(2730 kg) at maximum height (bucket pin), and breakout force (bucket on
ground) is 8838 lbs (4010 kg). The raising time is 4 sec from ground
line to full height, and bucket dumping time is 1 sec. The loader is
compatible with a 88" (2230 mm) bucket.
The MF 450 extendable backhoe operational data includes a bucket digging
force of 10756 lbs (4880 kg), and dipperstick digging force of 7604 lbs
(3450 kg). The max digging depth is 228" (5770 mm), and overall reach
from swing pivot is 269.4" (6840 mm) at ground line. The backhoe is
equipped with 16", 18", 24", 30" and 36" buckets.
