Kubota KX040-4 6-in-1 Blade



Angle Blade Optional Hydraulic Angle Blade*

Save time and work more efficiently. With a simple movement of the new thumb operated rocker switch on the dozer lever, the hydraulic angle blade (optional) can be angled to the right or left to push soil to the side as the machine moves forward, eliminating the need for repetitive repositioning at right angles when backfilling trenches.

*Available on KX033-4, KX040-4, KX057-5, KX080-4S

Hydraulic 6-in-1 Blade

Kubota's hydraulic 6-in-1 Blade can be angled right and left – and now, tilted as well. This blade enables six different positions: neutral, float-up, left-end-up, right-end-up, left-end-forward and right-end-forward. This feature makes leveling and backfilling work incredibly easy, even on inclines and uneven terrain, making you more productive and more efficient.

*Available on KX040-4

Clean Running Kubota Tier 4 Engine

Kubota excavators are all powered by Kubota Tier 4 emission engines. The modern engine design maximizes digging and lifting performance, delivers minimized noise and vibration and meets the latest engine emission regulation.

Two Speed Travel

All Kubota excavators have a two speed drive that allows for efficient machine maneuverability and backfill operations.

Changeable Control Pattern

Convenient Two-pattern Selection System (TPSS) allows you to change between ISO and SAE operating patterns with a quick flip of the TPSS switch – without tools or leaving your seat.
