ENGINE DETAIL
The Massey Ferguson 7620 tractor features a Sisu turbocharged 6-cylinder diesel engine with a 402.5 ci (6.6L) displacement, offering robust power for heavy-duty tasks while adhering to Interim Tier IV emissions standards through selective catalytic reduction (SCR). Its electronic high-pressure common rail fuel system enhances fuel efficiency and engine response, although maintenance of the SCR system is critical for compliance and optimal performance. With a compression ratio of 17.4:1 and a rated RPM of 2100, the tractor is well-suited for agricultural applications requiring both torque and reliability, though its emissions control system may pose challenges in terms of servicing and potential operational downtime.

| Type | six-speed power shift |
| Gears | 24 forward and reverse |
| Description | Six power shift gears in four ranges. |
TRANSMISSION 2
The Massey Ferguson 7620's Dyna-VT transmission offers infinite gear selection within two ranges, enabling seamless speed adjustment without interruption in power delivery. This continuously-variable transmission (CVT) enhances fuel efficiency and operational comfort, particularly in varied field applications where constant speed changes are required. However, potential challenges may include higher initial costs and maintenance complexity compared to traditional gear systems, which may affect long-term ownership decisions.
