The Dual Clutch consists of a forward (primary) pressure plate and dry cushioned disc which is attached to the transmission input shaft, and a rearward (secondary) pressure plate and dry disc which is attached to the hydraulic pump and power take-off input shaft. The primary pressure plate is spring-loaded by twelve silicon-chrome alloy coil springs located between the clutch cover and the primary pressure plate. The secondary pressure plate is spring-loaded by an annular Belleville type spring located between the clutch cover and the secondary pressure plate or false flywheel ring.

The false flywheel ring is interposed between and integrated with the primary and secondary clutch SUb-assemblies, and is secured to the flywheel by the same cap screws that attach the clutch cover. In operation, the clutch springs exert pressure against the clutch pressure plates, this in turn transmits the pressure through the discs to the false flywheel ring for the secondary clutch and to the engine flywheel for the primary clutch, thus establishing a firm frictional contact between the respective discs and flywheel faces.

Depressing the clutch pedal through the 1st stage moves the clutch release fork, which in turn contacts the clutch release bearing, moving it forward on the retainer and bringing it in contact with the clutch release fingers. The bearing depresses the fingers which in turn causes the primary pressure plate to retract from the disc and release the pressure on it. This interrupts the power flow to the transmission. Depressing the clutch pedal further through the 2nd stage (noticeable by an increased resistance to overcome) causes the same release fingers to move the primary pres­sure plate to a point where it contacts and causes the secondary pressure plate to retract from its respective disc, thus releasing the frictional contact between the disc and the false flywheel ring face. This interrupts the power flow to the hydraulic pump and power take-off input shaft.

The combination coil and Belleville spring dual clutch has been used in all 35 (MF & TO) tractors since Tractor Serial Number 177395, MF 50 Tractors since Tractor Serial Number 515395 and all models of the MF 65 Tractor.

The power take-off shaft,. shown in Fig. 1, projects from the rear of the tractor center housing and has a 1-3/8 inch spline with an annular groove for positive con­nection of implement couplings.

A removable cap protects the splines when the shaft is not in use. The shaft itself is supported at the rear by a ball bearing and at the front by a needle roller bearing. The pilot on the front of the PTO shaft inserts into a needle bearing in the hydraulic pump thus supporting the rear of the pump. Double seals keep dirt out of the bearing and prevent oil from leaking out of the differential center housing. The power take-off is engaged by a lever, located on the left side of the tractor center housing, which selects either proportional engine speed or proportional ground speed. The lever also has a neutral position which disconnects the drive.

LIVE PTO

The deluxe tractor is fitted with dual clutch and live PTO. The PTO drive from the engine is controlled by the clutch pedal in the bottom half of its range. The initial movement of the clutch disengages the transmission only; addit­ional downward· movement disconnects the hy­draulic pump and PTO shaft. On the basic tractor the hydraulic pump and PTO shaft and transmission are driven directly by the trans­mission counters haft , and on the deluxe tractor by a drive shaft which passes through a hollow countershaft assembly, and is therefore inde­pendent of the transmission.
