Machine Legacy And Manufacturer History
The 490E crawler excavator represents a mid-sized model produced by a renowned agricultural and construction equipment manufacturer that began operations over a century ago and evolved into a global leader in heavy machinery. The 490E was manufactured from the mid-1990s through 2021 and known for its adaptability and longevity, with a mass of about 12.1 metric tonnes and a track gauge of 600 mm . It marked a key segment offering between compact and large excavators, earning popularity among rental fleets and contractors seeking a balance of power and portability.
Bucket Variety And Technical Considerations
This excavator is compatible with a full suite of buckets tailored to a wide array of jobsite needs. Available variants include general-purpose, heavy-duty, and ditching buckets. Most of these come with adjustable side-clearance bushings, improving alignment and wear distribution, except for the ditching bucket .
Available tooth types include the manufacturer’s proprietary Fanggs® or the versatile ESCO Vertalok options. Replaceable cutting edges are standard parts, and optional side cutters can extend bucket width by approximately 150 mm (6 in) for enhanced performance .
Bucket Specifications (List Format)
Here’s a breakdown illustrating the bucket lineup—each entry captures width, volume, weight, and digging power using the shorter (8 ft 3 in) and longer (9 ft 11 in) arm configurations:
To match bucket size with material density and loading efficiency, typical guideline volumes are:
Terminology Notes
The 490E’s boom and arm offer two configurations:
Practical Recommendations
A contractor working on a municipal park project experimented with a 48-in general-purpose bucket to fill wheelbarrows quickly. However, when handling moist clay, the bucket overloaded each cycle, slowing the swings. Later, switching to a 36-in heavy-duty bucket cut cycle time by nearly 20 %, maintained momentum, and reduced fuel per cycle—demonstrating how optimal bucket sizing directly affects work rhythm.
Summary
The John Deere 490E excavator supports a broad suite of bucket options—general-purpose, heavy-duty, and ditching—spanning widths from 18 in to 60 in and with capacities up to around 1.06 cu yd. Choosing the right bucket means balancing material density, task type, and machine hydraulics. Understanding specifications, terminology, and field responses ensures operators can match bucket selection to maximize efficiency and productivity in diverse work conditions.

Bucket Specifications (List Format)
Here’s a breakdown illustrating the bucket lineup—each entry captures width, volume, weight, and digging power using the shorter (8 ft 3 in) and longer (9 ft 11 in) arm configurations:
- General-Purpose Buckets
- 18 in / 460 mm: ~0.34 cu yd (0.26 m³), 723 lb (328 kg)
- 24 in / 610 mm: ~0.50 cu yd (0.38 m³), 893 lb (405 kg)
- 30 in / 760 mm: ~0.64 cu yd (0.49 m³), 1,066 lb (484 kg)
- 36 in / 915 mm: ~0.78 cu yd (0.60 m³), 1,081 lb (490 kg)
- 42 in / 1065 mm: ~0.79 cu yd (0.60 m³), 926 lb (420 kg); or ~0.92 cu yd (0.70 m³), 1,244 lb (564 kg)
- 48 in / 1220 mm: ~1.06 cu yd (0.81 m³), 1,441 lb (654 kg)
- 18 in / 460 mm: ~0.34 cu yd (0.26 m³), 723 lb (328 kg)
- Heavy-Duty Buckets
- 18-42 in widths with similar capacities, heavier weight (e.g., 18 in @ 869 lb; 36 in @ 1,298 lb) .
- 18-42 in widths with similar capacities, heavier weight (e.g., 18 in @ 869 lb; 36 in @ 1,298 lb) .
- Ditching Buckets
- 48 in / 1220 mm, 0.67 cu yd (0.51 m³), 841 lb (381 kg)
- 60 in / 1525 mm, 0.90 cu yd (0.69 m³), 937 lb (425 kg) .
- 48 in / 1220 mm, 0.67 cu yd (0.51 m³), 841 lb (381 kg)
To match bucket size with material density and loading efficiency, typical guideline volumes are:
- Peat (700 lb/cu yd): ~3.25 cu yd (2.5 m³) with general-purpose bucket
- Topsoil (1,600 lb/cu yd): ~1.38 cu yd (1.1 m³)
- Sand, dry (2,400 lb/cu yd): ~0.88 cu yd (0.7 m³)
- Clay, wet (2,800 lb/cu yd): ~0.75 cu yd (0.6 m³)
- Sand and gravel, wet (3,400 lb/cu yd): ~0.63 cu yd (0.5 m³) .
Terminology Notes
- Adjustable side-clearance bushing: allows fine alignment of bucket to arm, reducing lateral wear.
- Cutting edge: removable or replaceable blade that takes contact abrasion.
- Ditching bucket: wide, shallow bucket designed for tasks like slope grading or ditch cleanup.
- Fanggs® vs Vertalok: two distinct tooth shapes; Fanggs® typically handle varied materials, Vertalok penetrate sharp surfaces and resist wear.
The 490E’s boom and arm offer two configurations:
- Short Arm (2.52 m / 8 ft 3 in):
- Max reach: ~27.0 ft; Dig depth: ~18 ft; Loading height: ~20 ft .
- Max reach: ~27.0 ft; Dig depth: ~18 ft; Loading height: ~20 ft .
- Long Arm (3.01 m / 9 ft 11 in):
- Max reach: ~28.9 ft; Dig depth: ~20 ft; Loading height: ~21 ft .
- Max reach: ~28.9 ft; Dig depth: ~20 ft; Loading height: ~21 ft .
- Operating weight: ~26,780 lb (~12,147 kg)
- Engine: 4-cylinder turbocharged 4045T, ~85 hp net
- Hydraulic flow: ~52 gpm (198 L/min); pressure: ~4,980 psi .
Practical Recommendations
- For general excavation in typical soils, a 30-36 in general-purpose bucket offers a practical balance.
- Denser materials like rock or saturated clay suit heavy-duty buckets in 30-36 in range.
- For surface work—ditch grading, slope cleaning—a 48–60 in ditching bucket improves coverage.
- Installing side cutters adds ~6 in width for trench clearance or when maneuverability is tight.
- Monitor cutting edge wear and replace proactively—extends bucket life and ensures consistent performance.
