Mini Excavator Rubber Track Replacement Cost in 2026

When rubber tracks wear out on a mini excavator, the replacement cost surprises most owners. Tracks are consumable items, but a full replacement on a popular 3-5 ton mini can run $2,500-$5,500 all in depending on the machine, the track choice, and your local shop rate.

Here is what to expect for the most common models, plus what drives the cost up or down.

Mini Excavator Track Replacement Cost by Model

Bobcat E35	300 mm	$1,400-$1,900	$300-$500	$1,700-$2,400
Kubota KX040	400 mm	$1,800-$2,400	$350-$550	$2,150-$2,950
Cat 305 / 305.5	400 mm	$1,900-$2,600	$400-$600	$2,300-$3,200
John Deere 35G	400 mm	$1,800-$2,400	$350-$550	$2,150-$2,950
Takeuchi TB240	400 mm	$2,000-$2,700	$400-$600	$2,400-$3,300

Komatsu PC88	450 mm	$2,300-$3,100	$450-$650	$2,750-$3,750

Parts cost assumes OEM-compatible rubber tracks from a quality aftermarket supplier. OEM dealer tracks run 15-30% higher. Labor assumes a shop rate of $110-$150 per hour, 2.5-4 hours per track.

What You Are Actually Paying For

The Tracks Themselves

Rubber tracks for mini excavators come in three price tiers. OEM parts from a dealer cost the most and are the safest fit. Quality aftermarket tracks from suppliers like Camso, McLaren, or Bridgestone run 10-20% less and perform comparably. Budget aftermarket from overseas suppliers are the cheapest option but wear faster and can develop cracking or delamination early.

For a machine you rely on, quality aftermarket is the right call most of the time. Budget tracks on a machine logging 400+ hours per year rarely save money over the ownership cycle.

Labor

Track replacement on a mini excavator takes 2.5-4 hours per track depending on the technician's experience and the machine's age. Older machines with dry or corroded track pins take longer. Most shops bill 1-2 hours for both tracks together on a straightforward job. Double that if the front idler or rear sprocket needs work at the same time.

What Gets Inspected at the Same Time

When tracks come off, a good shop will also check undercarriage components: front idler, rear sprocket teeth, top and bottom rollers, and track tension system. If your sprocket teeth are worn flat or rollers are leaking, replacing tracks and leaving the sprocket will chew through the new tracks quickly.

• Front idler replacement: $350-$700 parts, $200-$400 labor
• Rear sprocket replacement: $400-$900 parts, $300-$500 labor
• Bottom roller replacement: $120-$250 each, $150-$300 labor per roller

If your tracks wore out in under 1,200 hours, sprocket condition is likely the reason. Ask the shop to check before they reassemble.

When to Replace vs Repair

Rubber tracks on a mini excavator typically last 1,200-2,000 hours under normal conditions. Hard surfaces (concrete, asphalt, gravel) shorten that by 30-40%. Soft soil and dirt significantly extend track life.

Replace when you see:

• Exposed steel cords (the track is at the end of its life and can snap)
• Missing lugs, or lugs worn to less than 50% of original height
• Cracking between lugs or at the track edge (rubber delamination risk)
• A broken or bent track link (replace immediately, machine should not be operated)

Repairs are rarely cost-effective on rubber tracks. A cracked track that has not reached the steel cords can sometimes continue in service for a season, but plan the replacement. There is no good field repair for worn lugs.

Repair vs Sell: Know the Numbers

A $3,000 track replacement on a machine worth $35,000 makes sense. The same job on a machine worth $8,000 requires more thought. If the undercarriage is worn and the rest of the machine has deferred maintenance, repair costs can add up to more than the machine is worth.

Before you approve the repair, check what the machine is actually worth in its current condition and what it would be worth after the fix.
