Tractor overview
The Case IH Steiger 645 Quadtrac is a articulated crawler tractor designed around very high drawbar demand and broad-acre field work. Its 12.9 L FPT diesel produces 636.2 hp with 689.4 hp maximum output, while claimed PTO power is 529.6 hp. Power is managed through PowerDrive, and the articulated crawler chassis uses track belts instead of conventional tires to spread machine weight and maintain traction. Hydraulic capacity is 159.0 L/min; 215.7 L/min optional; 427.7 L/min optional with 10092 kg rear-hitch lift, supporting large seeding and tillage equipment. With a wheelbase of 391 cm and listed weight of 25764 kg shipping, this is a large-field machine rather than a general-purpose utility tractor. Buyers should focus on track condition, hydraulic specification, drawbar/hitch setup and transport constraints as much as headline horsepower.
Who this tractor suits
Not ideal for
- Small fields and tight farmyards
- Loader-style utility work
- Operations unable to accommodate very high purchase, transport and operating costs
Practical specification guide
What the headline specifications mean during real tractor work.
Engine and field power
The source lists 636.2 hp and 689.4 hp maximum power. This power level is intended for sustained high-load field operations rather than light utility work.
Powershift transmission
PowerDrive. Its fixed forward/reverse ranges are designed for maintaining pull under changing field loads.
Hydraulic capacity
Available pump flow is 159.0 L/min; 215.7 L/min optional; 427.7 L/min optional and rear lift is 10092 kg. High-flow options are especially important for modern large planters and air seeders.
Tracks and flotation
Track options are listed by the source. Wider belts generally increase flotation but also affect transport width and ground contact.
Weight and transport
Listed machine weight is 25764 kg shipping with a 391 cm wheelbase. Verify transport width, trailer capacity and local road limits before moving the tractor between distant fields.
Configuration & variant guide
Options and market differences that can change how this tractor is equipped or used.
| Option | Available setup | What it changes |
|---|---|---|
| Hydraulic pump | 159.0 L/min; 215.7 L/min optional; 427.7 L/min optional | Determines oil flow available to high-demand implements. |
| Track width | Track widths vary | Changes flotation, traction and transport width. |
| Rear hitch/drawbar | IVN | Match hitch/drawbar category and vertical load to the implement. |
| PTO | 1000 RPM | Relevant when the tractor will power large PTO-driven equipment. |
| Electrical package | 240 A | Higher alternator output can matter with displays, controllers and electrically intensive implements. |
CHECKPOINT 06
Strengths and considerations
What stands out
- Very high engine output for heavy field work
- Track chassis prioritizes traction and flotation
- High-capacity hydraulic system with optional higher flow on many models
- Heavy-duty rear hitch and 1000-rpm PTO capability
Check before buying
- Very large machine for small or irregular fields
- High purchase and operating cost
- Track condition and replacement cost are major ownership considerations
- Transport width and weight require planning
