Common questions about rubber track replacement
400 = width in millimeters (~15.7"). 72.5 = pitch — distance in mm between drive lugs. W = Wide guide — broader lug profile for wider undercarriage frames on larger mini excavators. 74 = total link count in the continuous loop. All four values must match your OEM track exactly — a one-link difference won't fit because the tension geometry is wrong. See How To Measure Rubber Tracks.
The 400x72.5Wx74 size is shared across multiple mini excavator models. Browse the 83 fitment listings in this collection — each is named by machine. Use the Rubber Track Finder filtered by size, or call (850) 816-7898 and we'll verify fitment by serial number before shipping.
Available tread patterns: Directional. Choose based on your jobsite mix — see the tread selection guide. C-Block lasts longest on hard surfaces, Multi-Bar is turf-friendly, Zig-Zag is the all-around standard, Directional maximizes straight-line traction.
Rubber tracks are sold individually unless specified otherwise. Most mini excavators use two tracks — order quantity 2 for a complete machine. Replace both tracks together: a worn track on one side and new on the other creates uneven sprocket and roller wear that shortens the life of both. See When To Replace Rubber Tracks.
The size stamped or embossed on your existing rubber track is the source of truth. If it shows 400x72.5Wx74, this is your replacement. If the OEM tag is unreadable, measure the width (mm across the lugs), count the links in the full loop, and check the pitch (mm between adjacent drive lugs) — see How To Measure Rubber Tracks. Or call (850) 816-7898 with your machine model and serial number.
