The New Holland E45SR is listed with more than one build of the same 400 mm track. Match link count to what is on the machine now. Free freight to the lower 48, 24-month warranty.
New Holland E45SR track options
- 400x72.5Nx74 — 400 mm (16") wide, 72.5 mm pitch, 74 links, narrow guide lugs
- 400x72.5Wx74 — 400 mm (16") wide, 72.5 mm pitch, 74 links, wide guide lugs
Same tread width on all of them — what changes is pitch and link count, which is set by the sprocket and roller frame. Read the numbers off the inside of the old track rather than going by model year; these were built across more than one undercarriage spec.
Tread choice for the New Holland E45SR
Size gets the track on the machine; tread decides how it works and how long it lasts. What we stock for this one:
- All-Terrain — everything in between. A compromise tread when the machine moves between surfaces
- MX — mixed and hard surfaces. A durable general-duty excavator tread
If the machine splits its time between surfaces, buy for the ground you are on most — a hard-surface tread on constant mud will spin, and a bar tread on concrete will wear out in half the hours.

How these wear
Excavator undercarriages load one side hard on slew and travel, so link cracking usually shows up before the tread wears out. Replace in pairs where you can: a new track running against a stretched one loads the drive unevenly and you will feel it in the steering.
Same track, other machines
Track size follows undercarriage geometry, not brand, so one of these sizes shows up on machines from several makers. If you run any of these alongside the New Holland E45SR, it is the same belt:
