Frequently Asked Questions

Common fitment, shipping, and rubber track replacement questions

What size rubber track does the Kubota KX040-4 use?
The Kubota KX040-4 uses a 350x54.5Nx86 rubber track. Note the K guide guide-lug type — other guide types won't seat correctly on the rollers. Always confirm against your current track or the machine's spec plate, since some units shipped with more than one option.
Will this track fit my Kubota KX040-4?
Yes — this track is matched to the Kubota KX040-4 by size and tread pattern. If your machine has a serial break or factory option, send the serial number and we'll verify fitment before shipping.
How long do Kubota KX040-4 rubber tracks last?
Most rubber tracks last 1,200–1,600 operating hours depending on terrain, alignment, and tension. Keeping tracks tensioned and clearing debris daily extends life.
Do Kubota KX040-4 tracks sell in pairs?
Tracks are priced individually; a full machine needs two. Most owners replace both at once so wear stays even.
Do you stock undercarriage parts for the Kubota KX040-4?
Yes — along with the rubber track we carry bottom rollers, drive sprockets, front idlers, top rollers for the Kubota KX040-4, so you can refresh the whole undercarriage in one order.
