U27-4: size and access first
The U27-4 has a 1,500 mm overall width and a 2,870 mm maximum digging depth. Its 4,680 mm digging radius at ground level describes a different working position from maximum depth. For a narrow access job, compare the route width, turning space and trench geometry before choosing the working tool.
Canopy and cab configurations
| Specification | Canopy | Cab |
|---|---|---|
| Operating weight, including 175 lb operator | 2,580 kg | 2,680 kg |
| Overall width | 1,500 mm | 1,500 mm |
| Overall height | 2,420 mm | 2,400 mm |
| Overall length | 4,100 mm | 4,100 mm |
| Engine | Kubota D1105-BH | Kubota D1105-BH |
| Gross / net power at 2,400 rpm | 15.6 / 14.9 kW | 15.6 / 14.9 kW |
The attachment uses auxiliary flow
The auxiliary circuit is 48 L/min. The main pump arrangement is 2 × 28.8 L/min plus 19.2 L/min; those pump values describe the machine system rather than a single attachment outlet. A breaker package uses its own flow and pressure window, and a tilt bucket or auger needs the appropriate direction and controls.
Compare the bucket task with the working range
| Measure | Value | Purchase decision |
|---|---|---|
| Maximum digging depth | 2,870 mm | Trench depth and arm configuration |
| Ground-level digging radius | 4,680 mm | Work position and reach |
| Maximum dumping height | 3,040 mm | Material placement or vehicle loading |
| Maximum bucket / arm breakout | 3,180 / 1,260 kgf | Digging-tool and soil task |
U27-4 parts and working tools
For engine-service items, use the D1105-BH engine plate with the machine serial. For pins, buckets and hitches, record both pin diameters, pin centres and ear width. For tracks, record the complete width/pitch/link marking. For a cylinder repair, identify the boom, arm, bucket or blade location and keep the old cylinder number with rod/bore sizes.
Prepare a practical purchase request
List the canopy/cab and arm configuration, required digging task, bucket width or drill diameter, old part numbers and quantities. Include the auxiliary hydraulic setup for powered tools and the delivery destination. Working tools and a maintenance or pin/bush package can be priced as separate lines in the same enquiry.
