Liebherr LR636 expert review

Reviewed by Jed H. on April 26, 2026

Overview

The Liebherr LR636 (2022–2025) is a practical crawler loader designed for material handling, site cleanup, and rough loading tasks. It delivers 135.05 kilowatt net power, a variable displacement hydraulic pump, and a tracked undercarriage, providing balanced performance across contractor and earthmoving work.

Expert rating: 5 stars

Pros Strong hydraulic response, good traction, and stable loading performance on rough ground.
Cons Tracked layout is slower than wheeled loaders, and value depends heavily on the actual machine spec and condition.

Performance & Efficiency

The D 934 A7 engine, 209.31 lpm hydraulic pump flow, and tracked undercarriage give the LR636 reliable performance for loading, cleanup, and routine contractor work, while the 0.49 m ground clearance and six track rollers per side help it stay effective on softer surfaces and mixed site ground.

In Comparison
