MT525B, MT535B, MT545B, MT555B Manual Extract – Gearbox

General

The gearbox housing comprises the following components:

• The power shuttle
• The input unit containing the Autopower IV gearbox input gear train
• The main gearbox
• The creeper unit (optional)

Each component is discussed in detail within the manual, focusing on their functionality and integration within the tractor.

Power Shuttle

The power shuttle includes two oil bath multidisc clutches (for forward and reverse operation) positioned at the front of the input unit, before the Autopower IV device. Controlled by two proportional solenoid valves, the power shuttle operation is managed via a lever located under the steering wheel, integrated with the tractor’s electronic system.

Autopower IV Input Unit Assembly

This assembly introduces four input gear ratios to the main unit, allowing for up to 32 gears in a direction. The unit utilizes hydraulic control with two epicyclic gear trains and hydraulic clutches to achieve this.

Gearbox Input Gear Train

The input gear train features two meshed pinions: a drive pinion at the rear of the power shuttle input unit and a driven pinion secured to the gearbox mainshaft. Its purpose is to transmit engine movement to the transmission via the power shuttle and Autopower IV hydraulic mechanism.
