Massey Ferguson 20C Backhoe Loader
The
Massey Ferguson 20C backhoe loader was manufactured from 1976 to 1982. The
components of MF 20C driveline system: a 152.7 cu.in (2.5 L) Perkins AD3.152
diesel engine with a rated power of 46.5 hp (34.7 kW), or 145 cu.in (2.4 L)
Continental gasoline engine with a rated power of 43 hp (32.2 kW), and manual
shuttle transmission with 6 forward and 6 reverse gears.
The maximum forward speed - 22.4 mph (36 km/h), a max reverse speed -
20.3 mph (32.6 km/h). The open center hydraulic system includes a gear
pump with rated fluid flow of 22 gpm (83.3 lpm). The hydraulic system
pressure is 172.5 bar (2500 psi). The Massey Ferguson 20C backhoe loader
is equipped with 7.50-16 or 11L-15 front tires and 14.9-24 rear tires.
The wheelbase is 77" (1950 mm).
The MF 32A loader has a maximum lift height of 124 in (3140 mm) at pin
and clearance with bucket dumped of 102 in (2590 mm). The lifting
capacity is 2800 lbs (1270 kg) to max height at pin, and boom breakout
force is 4500 lbs (2040 kg). The raising time is 3 seconds from ground
level to full height, and bucket dumping time is 2 sec. The 68" (1720
mm) loader bucket has a heaped capacity of 0.63 cu.yd (0.50 m3).
The MF 52A backhoe has a bucket digging force of 8850 lbs (4015 kg), and
dipperstick dig force of 5750 lbs (2610 kg). The digging depth at
maximum value is 139 in (3520 mm), and overall reach from swing pivot is
179 in (4540 mm) at ground line. The backhoe can be equipped with 24"
(610 mm), 30" (760 mm) and 36" (915 mm) buckets.
