3D machinecontrol.
Model-driven excavation with a 10.1-inch CAD display, dual GNSS and a 100 Hz IMU. The bucket follows the drawing — 10 mm horizontal, 15 mm vertical.
The drawing, in the cab
TX73 turns your design model into live bucket guidance — from highways and slopes to foundations and trenches.
Real-time 3D guidance
Bucket-tip position computed live against the design model, so the operator digs the drawing — not a guess.
Advanced CAD engine
Opens LandXML, DWG and DXF directly, plus .dc, .cal, .jxl, .lok and .loc coordinate files.
Color cut/fill maps
2D and 3D views with color-coded cut/fill and customizable operator shortcuts on a 1920×1200 display.
iSite cloud
Over-the-air updates, remote troubleshooting and data synchronization keep downtime near zero.
Tiltrotator ready
Automated tilt control for Engcon and Steelwrist tilt-rotators, tilt buckets and standard buckets.
Precision stack
MC300 GNSS at 8 mm + 1 ppm horizontal, IS300 100 Hz IMU at ±0.05°, dual IP68 AT315 antennas.
2.5D or 3D?
Both retrofit to your fleet. The question is whether your jobsites hand you design models.

Starting out? The same TX73 hardware also runs a 2D software tier — benchmark-led depth and slope, upgradeable to this full 3D at any time. Weighing up all three? See the full 2D vs 2.5D vs 3D breakdown.
