Its 10-hp engine pumps 5.3 gpm through its hydraulic lines, enough for its boom bucket to dig 6 ft deep and lift about 525 lbs. There’s a difference of opinion about what our customers want.”īobcat’s conventional compact excavator is the recently re-designated E10, which was introduced to the market in 2008 as model 418. “We haven’t come to a conclusion about whether to produce a complete electrical unit or a hybrid. In 2016, Bobcat rolled out a prototype of an electric compact excavator, but, as of December, the company had not introduced it to market. “There’s not sufficient demand for hybrids,” says Berkhimer, adding wryly, “Plus, we make diesel engines.” While he acknowledges that hybrids are available and less-polluting for interior work, “so far I haven’t seen a lot of demand for them.” Yet for all this rich heritage, Yanmar does not yet offer the newest market option - a hybrid model. Furthermore, the company is credited with building the first compact excavator, introducing it to the Japanese market in 1969. Yanmar engines, in fact, are the choice of some other compact excavator manufacturers. This is critical to rental companies because they can rent out the excavator and not have to worry about it.” “The engine is completely designed and built by us,” notes Berkhimer, “and Yanmar’s reputation was established on the reliability of its engines. One of the selling points for the SV08-1B is its engine, a 10.3-hp Tier 4 diesel powerplant. “The buckets are not much bigger than a shovel, but the excavator works a whole lot faster,” says Berkhimer. The company has three sizes of buckets - 8, 12 and 16 in. While Yanmar offers small breakers for the SV08, mulchers generally require more hydraulic flow. Like its competitors, it is mostly a breaking and digging machine for confined spaces.

The operator’s manual for the SV08 - which was introduced stateside in 2005 - advises that the machine not travel across a slope greater than 20 degrees nor be operated on a slope of any appreciable angle.Ĭat’s response to this market demand is the 300.9D, a compact excavator weighing slightly more than a ton with a three-cylinder diesel engine producing 13 hp. That is, the person at the excavator’s controls should not attempt to lift too much weight when the boom is extended to one side or another or operate on too steep a slope. In respect to the “tippability” of the company’s SV08-1B model, he says it is “really like anything else: Operators should not try to do too much.” “Proportionally, the stability of the unit is very similar to that of larger excavators,” says Eric Berkhimer, Yanmar USA product manager. Yet manufacturers say these excavators are as stable as larger ones, pound for pound. Our operator recommendation is that you operate the machine in the expanded mode.” “The narrow width is essential to get through doorways, but we at Bobcat are insistent that the only time the undercarriage should be retracted is when you need to pass through a doorway. “The retractable undercarriage, I would say, is a critical feature,” says Tom Connor, Bobcat excavator product specialist. On the other hand, with its treads extended outward, the 300.9D is a roomy 32 in.įor this small of an excavator, the machine’s ability to reduce its side-to-side profile is an essential characteristic. Sumo wrestling operators certainly won’t fit.
With its tracks pulled in under the cab, the 300.9D, for example, is only 28 in. All these excavators ride on retractable undercarriages that let them squeeze through narrow openings. Like most of its competitors, it creeps along at 1 to 2 mph. Twin hydraulic pumps can output 6 gpm at just under 2,500 psi.
The opportunity for small machines continues to grow.”Ĭat’s response to this market demand is the 300.9D, a compact excavator weighing slightly more than a ton with a three-cylinder diesel engine producing 13 hp. They want more machine labor than hand labor. “More and more customers want a machine to meet their requirements in the smallest package possible.
“We don’t work the same way we did in the past,” says Greg Worley, Caterpillar product application specialist. While their market share is compact, too, it is growing larger. By every definition, these are compact machines. They’re powered by engines of 10 to 15 hp and weigh just a ton, more or less. They are narrow and short enough to be driven through doorways. The smallest hydraulic excavators (with seats for operators) indeed are small.
