John Deere today announced the introduction of the 410H Backhoe, the construction industry's first machine with Total Machine Control (TMC).
TMC integrates control of every system in the machine, from engine to transmission and hydraulic functions to brakes, according to Bob Tyler, product marketing manager, John Deere Construction & Forestry Company.
The 410H, the first backhoe on the market to feature this technology, delivers high productivity through faster cycle times. A key feature that boosts cycle times is the three-speed backhoe hydraulics, which enables the operator to choose between three dig speeds. When the machine is started up, it will dig at exactly the same speed as a current Deere 410G will dig, which is effective in general trenching and other similar tasks. Select the fast mode, and the 410H backhoe with TMC will dig 30 percent faster than the current 410G; select slow mode, and the machine will dig 20 percent slower than current production.
A tool carrier option is available for the loader end of the 410H, which includes parallel lift as well as the new hydraulic quick coupler, both of which enhance productivity. Traditionally, tool carriers require significant linkage down the side of the loader arms. The 410H tool carrier option eliminates all that linkage, which saves on maintenance costs and makes the machine considerably easier to service. The newly designed loader arms and coupler provide the industry's best truck height visibility. Bucket and attachment options from John Deere's Worksite Pro line make the 410H one of the most flexible machines of its kind on the market.
In addition to the parallel lift found on the tool carrier option, the 410H also provides some automated features not generally found on a backhoe. One of these features, return-to-carry, enables the operator to simply push the lever forward and let go of the joystick after dumping a load; the boom will automatically return to a position that's just above the ground, ready for another cycle.
Another automated feature offered on the 410H is boom height kick-out, which allows the operator to set the loader boom height to fit working conditions.
Auto-idle, an automated feature that enhances fuel efficiency, also is provided on the 410H. If the operator releases the backhoe controls for more than four seconds, the engine automatically reverts to idle, which saves fuel and reduces noise. In addition, the system ensures that if a hose is accidentally damaged, the boom stays in place. Hose burst protection helps further minimize operating costs.
The machine design features all the conveniences of the previous model, with several new features that enhance comfort. Pilot controls are replaced by two joysticks, which are set into each arm rest for maximum convenience. The console also has been updated, with the same sealed switch keypad that's found on Deere loaders and motor graders.
