If your machine isn't listed, check your current track's sidewall marking — if it reads 300x52.5Wx78, this is your direct-fit replacement.

The size 300x52.5Wx78 describes the three key dimensions of the track: 300mm wide (11.8") × 52.5mm pitch (distance between lug centers) × 78 links (total lugs around the loop). All three numbers must match your current track — width determines machine fit, pitch must match the drive sprocket, and link count sets the overall track length.

The 300x52.5Wx78 comes in Directional tread only. V-shaped lugs act like paddles for maximum forward grip in loose dirt and sand. Streamlined lug design reduces rolling resistance for better fuel efficiency and faster travel across the jobsite. This is standard for mini excavators in this size range.

Most operators get 1,500–2,000 hours out of a set in general construction use. Rocky ground, concrete yards, or demolition work drops that to 800–1,200 hours. Snow, turf, and dirt work push it past 2,500 hours with good maintenance. Inspect monthly — replace when lugs are worn to half-height or you see exposed steel cord.

General rule of thumb: replace sprockets every other track change. However, if you operate in sand, rocky ground, or demolition environments, sprocket wear accelerates and you should inspect — and often replace — with every track change. Worn sprockets (hooked teeth, flattened profile) will destroy a brand-new track within 200 hours. If in doubt, replace them together — cheaper than a ruined track.
