Understanding the Dimension Parameters
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 (109 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 109 mm pitch with the existing sprocket before ordering.
The link count (39) 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.
300X109X39K rubber track photos
Photos are matched by full width, pitch and link count. Nearby references are shown when the exact photo is not available.
300X109 rubber track section drawing
Section drawings are matched by width and pitch because they do not include link count.
Application Scenarios
Agricultural Machinery
Rubber tracks for harvesters, compact tractors and muddy field conditions.
Construction Equipment
Excavators, mini diggers and compact loaders that need stable grip and wear resistance.
Special Vehicles
Tracked carriers and special-purpose machines that need replacement size references.
Maintenance and Replacement
Useful for wear diagnosis, model matching and old-track replacement planning.
Nearby Size Comparison
Compare 300X109X39K with nearby specifications that share the same width or pitch. Check size pages for exact machine fitments, photos and section drawings before final selection.

Installation & Tensioning Notes
Track Tension Check
For 300X109X39K 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.
Installation Alignment
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.
Replacement Interval Reference
Typical replacement cycles for 300X109X39K depend on operating hours, ground conditions and tension maintenance. Inspect track surface, steel core exposure and link cracking at 500-hour intervals.
