Dingtai manufactures complete John Deere track groups, the assembly of link chains, pins, bushings, and track shoes driving excavator and dozer undercarriages.
We offer factory-direct supply and full OEM manufacturing services, producing custom track groups matched to John Deere machines for global distributors and equipment fleets.
Our track groups resist abrasive wear and pin/bushing elongation, preventing unscheduled downtime and extending undercarriage service life in demanding ground conditions.
With over 20 years of engineering experience, Dingtai operates under ISO9001 quality systems and SGS-certified materials, ensuring consistent, reliable track group production.
We use 35MnB steel links, deep induction hardening, and precision-ground pins and bushings to achieve uniform hardness and long life structure.
Core Selling Points
- Global Brand Compatibility: Our John Deere track groups match OEM pitch, link width, and bolt patterns for direct installation on popular excavator and dozer models.
- Premium 35MnB Material: Track links are forged from high-grade 35MnB steel, providing superior tensile strength and resistance to bending under heavy impact.
- Deep Quenching/Heat Treatment: Link rails, pins, and bushings receive deep induction hardening to 52-58 HRC for extended wear life and reduced elongation.
- 100% QC Inspection: Every track group is dimensionally inspected, hardness tested, and pre-assembled to verify pitch accuracy, torque, and surface finish before shipment.
Our catalog of John Deere Track group includes various specifications, fully compatible with John Deere excavators and bulldozers.

Technical Features
John Deere track groups consist of forged links, hardened pins, bushings, and bolted track shoes assembled to exact OEM pitch for smooth sprocket engagement.
Link rails are induction hardened to achieve deep martensitic structure, resisting rolling contact fatigue and reducing wear on idler and roller surfaces.
Pins and bushings are precision ground and case hardened, creating tight interference fits that prevent internal wear and track chain elongation under load.
Applications
- Mining: Heavy rock loading and haul road maintenance
- Road Construction: Subgrade preparation and asphalt paving support
- Quarrying: Abrasive limestone, granite, and aggregate extraction
- Demolition: Rubble and concrete processing on unstable ground
- Forestry: Mulching and land clearing on soft, uneven terrain
Frequently Asked Questions
What is the minimum order quantity for John Deere track groups?
MOQ is typically one complete track group or one pair; mixed model orders can be arranged for distributor stock.
What is the delivery time?
Standard delivery is 15–30 days after deposit, depending on model and quantity. Custom manufacturing may require 30–45 days.
What heat treatment depth do you guarantee?
Link rail hardening depth is 4–8 mm; pins and bushings achieve 58–62 HRC with case depth 2–4 mm.
Do you provide a warranty?
Yes, we offer 12 months or 2,000 hours against manufacturing defects under normal operating conditions.
How do I match my John Deere part number?
Send your OEM part number or track group drawing; our engineers verify pitch, link count, shoe width, and bolt hole dimensions.
Can you produce custom track shoe widths or bolt patterns?
Yes, we manufacture custom track shoes, grouser heights, and bolt patterns according to your undercarriage requirements.
Maintenance Guide
- Check track sag daily and adjust tension per John Deere specifications to prevent excessive bushing and sprocket wear.
- Inspect pin and bushing joints for oil leakage, dry wear, or elongation; measure pitch across four link sections monthly.
- Rotate or turn pins and bushings at 50–70% wear to extend service life before full track group replacement.
- Replace track groups when link rail height is worn beyond 20% or shoes show cracked grouser bars and loose bolts.
