Models 420D and 430D backhoe loaders, and 420D IT and 430D IT integrated toolcarrier (IT) configurations, offer new single-lever, pilot-operated, excavator-style joystick controls for smooth, hydraulic loader functions. New models feature Cat 3054T turbocharged, direct-injection. 4-cylinder engines with 4.0 liters displacement, fuel-injection, and Power-Shuttle transmission with on-the-go shitting and synchromesh in 4 forward and 4 reverse gears. Auto-shift option with manual override automatically shifts between second gear and highest selected gear in 5 forward and 3 reverse speeds. Also have standard 2-wheel or on-the-go, all-wheel drive with oil-immersed hydraulic, multiple disc brakes. 420D has 85 net hp. and backhoe digging depth of 14 ft. 5 in. with standard stick; extendible stick pushes depth to 18 It. 1 in. 430D has 94 net hp. and digging depth of 15 ft. 3 in., extendible to 19 ft. l I in. Variable-flow, closed-center, load-sensing hydraulic system adjusts flow and pressure to 3,300 p.s.i. for full hydraulic force to work tools at any engine speed. Single-pin backhoe bucket has 205[degrees] linkage rotation with integrated lifting eye. Operator station includes white-faced gauges, hand throttle, new boom lock position, and pilot-operated stabilizer controls. A portable backhoe that can be towed to a job site, unhooked, and then used has been introduced. Heavy enough for commercial use, the backhoe is ideal for use by farmers, plumbing contractors, homebuilders, landscape contractors, and large-scale gardeners.

[ILLUSTRATION OMITTED]Size matters. It''s easy to see why an SDS-max rotary hammer (the red Milwaukee) is the best tool for big holes and frequent use. The ample size reduces vibration, and stout motors can turn 2-inch spiral bits. The blue cordless Makita SDS-plus rotary hammer (bottom) is handy, but its smaller chuck and motor are meant only for bits up to 3/4 inch. The 1/2-inch DeWalt hammer drill (right) is versatile, but drilling in hard concrete is slow and the conventional chuck isn''t made for heavy pounding.
