Our take on the Kubota KX040-5 Compact Excavator

The Kubota KX040-5 is a 4-ton-class compact excavator with a 40.3 HP gross diesel engine, an enclosed cab with A/C, and a digging depth of 11 feet 2 inches. It weighs about 9,182 lb and is 66.9 inches wide, so it fits through gates and works tight residential and utility jobs. The listed best new price is $450 at Mountains Reign Equipment as of November 4, 2026, with two stores pricing it new; that figure is far below what a new KX040-5 typically costs, so confirm what the $450 listing actually covers before treating it as the machine's price.

Pros
  • Enclosed cab with cold A/C for long summer shifts
  • 11 ft 2 in digging depth is strong for its size
  • 66.9 in width passes most residential gates
  • Angle blade and coupler options add grading and attachment flexibility
  • Kubota's dealer network and parts availability are broad
Cons
  • 9,182 lb operating weight needs a sizable trailer and tow vehicle
  • 40.3 HP gross is modest for heavy trenching in hard ground
  • New units are expensive; the $450 listing needs verification
  • Enclosed cab raises height to 97.6 in, a limit for low clearances

Questions and answers

Is the $450 price real for a new KX040-5?
The listing shows $450 at Mountains Reign Equipment as of November 4, 2026, but a new KX040-5 normally sells for tens of thousands of dollars. Ask the store exactly what the $450 covers, such as a deposit or an attachment, before relying on it.
How does the KX040-5 compare with the KX040-4?
The -5 update brought a redesigned cab, updated controls and improved service access while keeping the same 40.3 HP engine and roughly 11-foot digging depth. If price matters more than cab comfort, a clean -4 is worth comparing.
What can the KX040-5 lift and dig?
It digs to 11 ft 2.3 in and weighs 9,182 lb, which puts it in the 4-ton class. Lift capacity depends on the blade position and attachment, so check the load chart for your coupler and bucket.
Does it come with a coupler and blade?
The listed unit includes a coupler, modem and wire harness, and the page notes an angle blade. Confirm the bucket and blade configuration with the seller, since attachments vary by unit.
Can I tow it with a pickup?
At 9,182 lb plus a trailer, you need a heavy-duty trailer and a truck rated well above that combined weight. Most half-ton pickups are not enough.
When is the best time to buy?
Compact excavator pricing tends to soften in late fall and winter when construction slows. Watch the price history and compare the two new listings before committing.
Where is the Kubota KX040-5 Compact Excavator cheapest?
At Mountains Reign Equipment, for $450.00, as of our latest check.
