Kubota B7100HST Tractor
The
Kubota B7100HST is a 2WD or 4WD compact utility tractor. This model was
manufactured between 1977 and 1997. The tractor was designed in 2 versions:
B7100HST-E (2WD) and B7100HST-D (4WD).
The Kubota B7100HST powertrain system components: a 46.5 cu.in (0.8L)
Kubota D750 4-cycle vertical 3-cylinder indirect injection naturally
aspirated water-cooled diesel engine with a maximum power of 16 hp (11.9
kW), and two-range hydrostatic transmission with infinite forward and
reverse gears.
Max forward speed: 3.5 mph (5.7 km/h) using low range or 9.1 mph (14.5
km/h) using high range, and max reverse speed: 2.4 mph (3.9 km/h) using
low range or 6.2 mph (10.1 km/h) using high range. The open center
hydraulic system used a gear pump with fluid flow rate of 3 gal/min
(11.4 l/min). The hydraulic pressure is 117 bar (1700 psi).
The two-wheel drive models are equipped with 4.00x9 front tires and
7.00x16 rear tires. The 6.00x12 (AG) or 20.5x8.00-10 (Turf) front tires
and 8.00x16 (AG) or 29x12.00-15 (Turf) rear tires are used for tractors
with four-wheel drive. The wheelbase is 54.6" (1390 mm) for 2WD models
and 55.1" (1400 mm) for 4WD models. The Kubota B7100HST is compatible
with a Kubota B1630C front-end loader with lift capacity to full height
of 510 lbs (230 kg) and breakout force of 780 lbs (353 kg).
