Table of Contents

  • Overview
  • Specifications

Buying the Track Loader Evolution set means choosing the relationship between the 977D and 963K, as well as the individual miniatures. Its 44-page history book and shared base make the pairing useful as a small exhibit. They do not make the two loaders equally capable of every working pose.

The newer loader is not automatically the more flexible miniature

In the inspection of set 85559, the 977D reaches higher, while the 963K has restricted lift and lacks a low bucket carry position. That reverses an easy assumption: a more modern subject does not necessarily give the model a wider usable range.

If you want to separate the pair into working scenes, assign each a task independently. Do not order a companion truck for both based on one loader’s raised-bucket photograph. The older model’s stiff, linked tracks are another reason to treat this as a display purchase rather than expecting effortless movement.

Make the book part of the purchase

  • For a historical exhibit: confirm the two models, base and book are included in the actual offer.
  • For an existing loader collection: decide whether the second subject adds a meaningful contrast, rather than counting two models as an automatic bargain.
  • For a small shelf: obtain the complete base footprint. Individual model dimensions do not describe the assembled presentation.

The used Evolution set guide helps turn that contents check into specific seller questions without assuming every second-hand set is complete.

Pros & Cons Analysis

See the source attributions and review limitations below.

Pros

  • The inspected set combines two models with a 44-page history book. That supports a compact subject-focused exhibit, provided those contents are present in the offer.

Cons

  • The inspection reports restricted 963K lift and no low bucket carry position; its ripper also has little downward travel. A realistic loading scene should be checked before selecting it.
  • The 977D tracks were stiff and linked together. Treat that as a sample-level handling observation, not a reason to force them.

Keep the loader generations together—or judge them separately

The strongest purchase is the paired 977D/963K exhibit, complete with its historical booklet. That relationship gives 85559 a purpose a single loader cannot supply.

  • Mounted history display: confirm the pair and presentation contents are complete.
  • Independent work scenes: assess each machine’s needed pose. The 963K’s restricted lift/carry movement and the inspected 977D’s stiff tracks are different limitations.

The set should not be treated as a shortcut to two unrestricted working models.

Frequently Asked Questions

Are the dimensions for the entire set?

The merchant lists individual machine dimensions. They do not establish the footprint of the complete base and packaging.

Do both loaders in 85559 offer the same working poses?

No. The inspection describes different movement limits, including restricted lift and no low carry position on the 963K. Assess each machine rather than treating the pair as two equivalent working models.
