Kubota unveiled two new tractor-loader-backhoes, the L47 and M62, at the World of Concrete show back in February. The new models replace the L39, L45 and M59, joining the popular B26 to round out Kubota’s TLB line.
Kubota says the new TLBs offer more features for comfort and convenience. For instance, the clutch pedal has been eliminated, allowing the brake pedal to be relocated to the left side of the cab, reducing interior clutter and simplifying driver operation. The new TLBs are also more powerful and efficient. For instance, the M62 features highly efficient backhoes that dig deeper and reach farther than previous models. Additionally, both new models feature the ability to utilize certain Kubota mini-excavator buckets, which can provide for more versatility on the jobsite.
The new TLBs also feature an optional single-lever hydraulic hookup for quick coupling and uncoupling of front implements, providing for efficient three-in-one capability: front loader, backhoe and tractor work. With the hydraulic coupler, the operator needs only to press two dashboard buttons to release the levers securing the front implement. After backing away and proceeding to the next attachment, pressing the buttons again re-engages the levers and secures the new implement. The operator never has to exit the machine.
Additionally, the backhoe’s quick coupler allows for easy switching of Kubota excavator buckets, and a four-point rear quick-mount system allows for easy detachment of the backhoe when it’s not needed. Even more work duties can be handled with the aid of an independent PTO that enables the TLBs to get even more work done by attaching a wide range of PTO-driven implements, including rotary tillers, snow blowers and rear-mounted mowers – and because the PTO is hydraulic-independent, operators can engage and disengage without stopping the tractor.
M62 breaks into new digging depth category. Along with a productive front loader and powerful tractor, the M62 TLBs features highly efficient backhoes that dig deeper and reach farther than previous models. Additionally, both new models feature the ability to utilize certain Kubota mini-excavator buckets, which can provide for more versatility on the jobsite. Kubota’s L47 boasts a 10-foot digging depth and a bucket digging force of 5,825 pounds. The M62 offers contractors even greater excavating ability than its predecessors, with a 14-foot digging depth, a 17% improvement over the previous generation’s 12-foot max depth. The M62 has a bucket digging force of 6,572 pounds. On both TLB models, a lever-engaged backhoe crawling mode allows the operator to slowly creep forward or backward while remaining at the backhoe controls, saving time and enabling more sure-footed operation such as when working alongside a trench.
New Diesel Engines: Cleaner, More Powerful, Longer Range. The L47 and M62 are powered by turbocharged four-cylinder diesel engines that use a Common-Rail direct injection system, which, along with Exhaust Gas Recirculation (EGR) and Diesel Particulate Filters (DPF), enable compliance with Tier 4 Final emissions regulations. In addition, both engines are more powerful than their predecessors; the L47’s engine produces a rated 47.1 gross horsepower, while the M62 produces a rated 63 gross horsepower. The L47 and M62 are equipped with a much larger 17.7-gallon fuel tank—that’s boasting up to 48% more fuel capacity than those of the previous TLBs, allowing both new models to work longer, with less downtime required to refuel.
Increased Comfort and Convenience. The L47 and M62 host a number of interior upgrades that are aimed at increasing functionality and optimizing operator comfort. In both models the clutch pedal has been eliminated, thereby allowing the brake pedal to be relocated to the left side of the cab, reducing interior clutter and simplifying driver operation. Foot space on the backhoe platform has been increased 27% over the previous models, providing the operator with a roomier work area. A new throttle-up switch increases engine rpm while holding vehicle speed steady for those times when extra power is required for front loader work but vehicle speed needs to remain constant, and the electronic throttle lever and PTO switch require less physical effort to engage than older mechanical controls.
