Takeuchi TL6R Troubleshooting
The
Takeuchi TL6R compact track loader is powered by Kubota V2403-CR-TE4B vertical
inline four-cylinder direct injection turbocharged diesel engine with a rated
power of 65.2 hp (48.6 kW) at 2700 rpm. The Takeuchi TL6R is equipped with a
two-speed hydrostatic transmission, radial-lift loader boom, hydraulic self
leveling, 12.6" (320 mm) rubber tracks, and track rollers with metal face seals.
The hydraulic system has a pump with fluid flow rate of 17.8 gpm (67.4 lpm). The
track loader has a rated operating capacity of 2635 lbs (1195 kg) and tipping
load of 5270 lbs (2390 kg). The max lift height is 114.4" (2905 mm) to hinge
pin, and bucket breakout force is 5930 lbs (2690 kg).
