The track width (300 mm) determines ground contact area and flotation. A wider track distributes machine weight more evenly, which helps on soft or muddy ground. Matching width to machine spec is important for stability and undercarriage clearance.
The pitch (55.5 mm) is the distance between two adjacent drive lugs. It must match the drive sprocket tooth spacing exactly — even a 1 mm mismatch causes accelerated sprocket and lug wear. When replacing tracks, confirm 55.5 mm pitch with the existing sprocket before ordering.
The link count (78) sets the total track circumference. A higher link count on the same width and pitch means a longer track for larger machines. Always verify link count against the original track marking or machine manual.
Photos are matched by full width, pitch and link count. Nearby references are shown when the exact photo is not available.
Section drawings are matched by width and pitch because they do not include link count.
Rubber tracks for harvesters, compact tractors and muddy field conditions.
Excavators, mini diggers and compact loaders that need stable grip and wear resistance.
Tracked carriers and special-purpose machines that need replacement size references.
Useful for wear diagnosis, model matching and old-track replacement planning.
Compare 300X55.5X78Y with nearby specifications that share the same width or pitch. Check size pages for exact machine fitments, photos and section drawings before final selection.

For 300X55.5X78Y rubber tracks, sag should be 10–15 mm when measured mid-span under light hand pressure. Over-tensioning accelerates wear on drive lugs, sprockets and idlers.
Check that the drive sprocket, idler and roller alignment is within tolerance before mounting. Misalignment causes uneven edge wear and shortens track life regardless of size.
Typical replacement cycles for 300X55.5X78Y depend on operating hours, ground conditions and tension maintenance. Inspect track surface, steel core exposure and link cracking at 500-hour intervals.
