The
Kubota L3750 L-series compact utility tractor was manufactured from 1984 to
1990. The tractor was designed in 2 versions: L3750F (2WD) and L3750DT (4WD).
The Kubota L3750 powerline system components: Kubota F2302-DI 5-cylinder
direct injection water-cooled naturally aspirated diesel engine and
partially synchronized transmission with 8 forward and 8 reverse gears.
A 141.9 cubic inches (2.3L) engine has a cylinder bore of 3.35" (85 mm),
piston stroke of 3.23" (82 mm), and rated power of 45 hp (33.6 kW).
The maximum travel speed (forward/reverse): 14.2 mph (22.8 km/h). The
open center hydraulic system used a gear pump with rated capacity of 8.7
gal/min(32.9 l/min). The hydraulic system pressure is 172.5 bar (2500
psi). The 2-wheel drive models are equipped with 6.50x16 front tyres and
13.6x28 rear tyres. The 9.50x16 front tyres and 13.6x28 rear tyres fit
4-wheel drive tractors. The wheelbase is 76.4" (1940 mm).
Compatible attachments for the Kubota L3750 tractor: Kubota BF900 loader
with lift capacity to full height of 1985 lbs (900 kg), and Kubota L4540
backhoe with maximum digging depth of 123" (3120 mm) and bucket digging
force of 3980 lbs (1805 kg).
