Kubota BX25 Backhoe Loader

The Kubota BX25 tractor loader backhoe was manufactured from 2009 to 2013. The components of Kubota BX25 TLB powertrain system: Kubota D902-E3 3-cylinder vertical indirect injection water-cooled diesel engine, and 2-range hydrostatic transmission with infinite forward and reverse gears.

A 54.8 cubic inches (0.9 L) engine has a cylinder bore of 2.83 in (72 mm), piston stroke of 2.9 in (73.6 mm), and maximum power of 23 hp (17.2 kW). The max travel speed (forward and reverse): 8.4 mph (13.5 km/h) / 6.2 mph (10 km/h). The open center hydraulic system includes a gear pump with fluid flow rate of 6.3 gpm (23.8 lpm). The Kubota BX25 backhoe loader is fitted with a hydrostatic power steering, wet disc brakes, 18x8.50-10 front tires, and 26x12.0-12 rear tires. The wheelbase is 55.1 in (1400 mm).

The Kubota LA240 loader has a maximum lift height of 71.3 in (1810 mm) at pin and bucket dump clearance of 52.4 in (1330 mm). The lifting capacity is 745 lbs (337 kg) at max height (pivot pin), and bucket's breakout force is 992 lbs (449 kg). The raising time is 3.5 seconds from ground line to maximum height, and bucket dump time is 1.7 sec. The 48 in (1220 mm) standard material bucket has a rated capacity of 6.1 cu.ft (0.17 m3).

The Kubota BT601 backhoe has a bucket dig force of 1936 lbs (880 kg) and dipperstick dig force of 1170 lbs (530 kg). The digging depth at maximum value is 74.4 in (1890 mm), and a reach from swing pivot is 102.8 in (2612 mm) at ground line. The backhoe can be equipped with 8 in (203 mm) and 12 in (305 mm) buckets.
