CAT 424 B2 vs JCB 3DX – Comparing Specs & Prices

Posted on March 31, 2026March 31, 2026 by admin

Backhoe loaders are the backbone of India’s construction, mining, and infrastructure sectors. Among all brands, CAT and JCB dominate the market — and two of their most popular models, CAT 424 B2 and JCB 3DX, are often compared head‑to‑head.

If you’re planning to buy a backhoe loader for earthmoving, roadwork, or general construction, this detailed, specification‑by‑specification comparison will help you choose the right machine for your project scale, terrain, and operating conditions.

⭐Price Comparison

Model Variant Ex‑Showroom Price
CAT 424 B2 Base ₹34.00 Lakh
JCB 3DX Base ₹35.00 Lakh

The prices listed — ₹34–35 lakh for CAT 424 B2 and ₹35–38 lakh for JCB 3DX — are Indian ex-showroom prices. These figures are based on comparisons from Indian construction equipment portals and reflect the cost in India, not the USA.
