Can I fit wider track shoes on a Komatsu D65 for soft ground?

Expert Answer

Yes, wider track shoes can improve flotation on soft, muddy, or wet ground because they spread the machine’s weight over a larger area and reduce ground pressure. On a Komatsu D65, though, the shoe width should be chosen for the actual job mix, not just the softest conditions, because going too wide can increase undercarriage load, side stress in turns, and wear on firm or rocky ground.

The right choice depends on the exact D65 variant and undercarriage arrangement, especially the track frame clearance, roller and idler condition, chain pitch, and the type of shoe system already fitted. For soft ground, people often look at swamp/LGP-style shoes, but the best width still has to leave safe clearance through the full travel of the track and during steering. If the machine works on clay or wet soil most of the time, a wider shoe may be helpful; if it also runs on hard ground, slopes, or broken rock, a narrower shoe may be the better long-term option.

Good signs that you may need more flotation include sinkage, spinning tracks, poor steering control in mud, or the machine “plowing” instead of carrying. Signs the shoe is too wide include heavier steering effort, more vibration, increased track wear, loose hardware, or rubbing/contact with the undercarriage or frame. As a rule, the narrowest shoe that still gives adequate flotation is usually the safest starting point.

Common mistakes to avoid: fitting wider shoes without checking side clearance, choosing width only from a similar-looking machine, or ignoring the rest of the undercarriage setup. Wider shoes can also expose weak rollers, worn pins and bushings, or incorrect track tension.
