Overview of the CAT 247B Multi-Terrain Loader
The 2006 Caterpillar 247B is part of CAT’s multi-terrain loader lineup—a hybrid between traditional skid steers and compact track loaders. Designed for low ground pressure and high maneuverability, the 247B is often used for snow removal, landscaping, soil grading, and light construction. With a rubber track undercarriage and a suspended bogie system, it offers a smoother ride and better traction than wheeled skid steers, especially on soft or uneven terrain.
Undercarriage Design and Wear Patterns
One of the most critical components of the 247B is its undercarriage. Unlike rigid steel track systems, the 247B uses a rubber track system with multiple bogie wheels and idlers. This design reduces ground disturbance and improves operator comfort, but it also introduces unique wear challenges.
Key components include:
A cabin builder in northern Minnesota purchased a 247B with 2,200 hours and used it extensively for hauling materials, grading, and snow clearing. After several seasons, he noticed the tracks looked fine externally but began losing drive lugs. He also had to replace several rollers and idlers, especially the inner ones. His advice: always inspect the undercarriage thoroughly and factor replacement costs into the purchase price.
Another operator with over 6,600 hours on multiple 247B units reported that rubber damage on idlers didn’t affect performance unless the bearings failed. He emphasized that track delamination and lug loss were the real concerns, typically appearing after 1,500 hours.
Maintenance Recommendations
Pros:
The 2006 CAT 247B is a capable and versatile multi-terrain loader, especially suited for property maintenance, snow clearing, and light construction. Its smooth ride and low ground pressure make it ideal for sensitive surfaces. However, prospective buyers should pay close attention to the undercarriage—particularly the condition of tracks, idlers, and bogie wheels. With proper inspection and maintenance, the 247B can deliver reliable performance for years, but neglecting its wear-prone components can lead to unexpected downtime and repair costs.

Key components include:
- Rubber Tracks
Provide flotation and traction but are vulnerable to delamination and drive lug failure after 1,500–2,000 hours.
- Bogie Wheels
Support the track and absorb shock. Bearings can fail over time, leading to wheel separation.
- Front and Rear Idlers
Guide the track and maintain tension. Inside idlers tend to wear faster due to debris accumulation.
- Drive Lugs
Molded into the track and engage with the sprockets. These can shear off as rubber ages or if the track delaminates.
- Multi-Terrain Loader (MTL): A machine designed for low ground pressure and high traction, using rubber tracks and a suspended undercarriage.
- Drive Lug: Raised rubber tabs on the inside of the track that engage with the drive sprocket.
- Idler: A wheel that guides the track and maintains tension but does not drive it.
- Delamination: Separation of the track’s rubber layers, often leading to failure.

Maintenance Recommendations
- Inspect Tracks for Lug Integrity
Even if the tread looks good, check for missing or cracked drive lugs.
- Check Idler Bearings
Spin each idler manually and listen for grinding or wobble. Replace if loose or noisy.
- Monitor Bogie Wheel Condition
Look for flat spots, rubber chunking, or bearing play.
- Clean Undercarriage Regularly
Remove rocks and debris to prevent premature wear.
- Lubricate Pivot Points and Bearings
Use high-quality grease and follow CAT’s service intervals.
- Track Replacement Planning
Budget for new tracks every 1,500–2,000 hours depending on terrain and usage.
- Operating weight: ~7,500 lbs
- Rated operating capacity: ~2,000 lbs
- Ground pressure: ~3.5 psi
- Hydraulic flow: ~15–22 GPM (standard vs. high flow)
- Engine: CAT 3024C, ~61 hp
Pros:
- Excellent traction on snow, mud, and soft soil
- Smooth ride due to suspended undercarriage
- Versatile for residential and light commercial use
- Easy to maneuver in tight spaces
- Undercarriage components wear faster than rigid systems
- Track replacement can be costly
- Limited lifting capacity compared to larger CTLs
- Rubber tracks less durable in demolition or rocky terrain
