MF 750 and-MF 760 COMBINES

Massey Ferguson

INTRODUCTION The information in this Manual describes the operation, maintenance and ser­

vicing of your Combine to help you keep up with the harvest and "on-the-go".

The information is applicable to both M F 750 and M F 760 Combines unless one particular Combine is specified in the text.

The money you have invested in your Combine will be better spent if you take the time to read this Manual and get to know it. Every piece of machinery feels better, works better and becomes more efficient when you are familiar with it.

Don't neglect the maintenance that is recommended.

A machine which is properly maintained pays a bigger dividend than one which is neglected. The maintenance and servicing described in this Manual can all be done with tools ordinarily available.

Massey-Ferguson has engineered and tested these Combines under all kinds of conditions to produce a superior machine. They have kept it as simple as possible, so you can do many small jobs. This Manual will help you, the operator, get the most out of your MF Combine.

NOTE: The reference to left-hand and right-hand used throughout this Manual re­fers to the position when seated in the operator's seat, facing forward.

IMPORTANT This Manual contains tables and other references to the settings of certain Com­bine components. As it is impractical to provide recommended or actual settings for every crop, every condition of crop, soil or weather, etc., the settings given in this Manual are INITIAL SETTINGS. This means, under normal or average condi­tions, these settings should be used as a STARTING POINT and then further adjustments made, as necessary, to suit specific conditions.

OIL PRESSURE GAUGE (Fig. 1)

Registers pressure of oil inside the engine.

AMMETER (Fig. 1)

Registers charge or discharge rate of. battery. When engine starts, needle will show charge and then settle to cen­ter position.

NOTE: The ammeter does NOT reg­ister the output of the alternator.

ENGINE TEMPERATURE GAUGE (Fig. 1)

.Registers temperature of engine coolmg system. Engine should operate with needle in the green section which is the normal operating range.

NOTE: (MF 760) To prevent the en­gine from overheating, should the temperature become excessive, a solenoid switch is activated which will stop the engine. See "Engine Starting" and "Driving the Com­bine" in this section.

TRANSMISSION CONTROLS

TRANSMISSION GEAR SELECTORS (Fig. 3)

The transmission has TWO selector levers, BOTH of which MUST be en­gaged to complete the transmission gear train.

To select 1 st gear, BOTH levers must be selected to 1, similarly, to select 3rd gear, BOTH levers are selected to 3 in their respective quadrants. '

REVERSE GEAR (Standard Transmission)

For Combines with standard trans­mission, select both levers to R (Reverse) position.

NOTE: There is no reverse section on the gearshift for Combines with hydrostatic transmission. See "Ground Speed Control Lever (Hy­drostatic Transmission)" in later paragraph.

TRACTION CLUTCH PEDAL (Standard Transmission) (Fig. 3)

Depress the pedal to disengage the traction clutch before selecting or changing transmission gears.

The clutch pedal cannot be de-

pressed when the parking brake is en­gaged.

IMPORTANT: The Combine MUST be stopped before changing trans­mission gears.

TRANSMISSION (Pressure) RELEASE PEDAL (Hydrostatic Transmission) (Fig. 3) .

Depress the pedal to release hy­draulic pressure in the hydrostatic trans­mission for stopping the Combine.

The pressure is released only when the pedal is being depressed. When the pedal is released the pressure will build up again.

GROUND SPEED CONTROL LEVER (Standard Transmission) (Fig. 1)

Move the lever forward to increase ground speed or pull the lever back to de­crease speed (after transmission gear has been selected). When desired speed is obtained, release lever to allow it to return to neutral.

the speed of the reel, and pull the switch back to decrease. The switch is spring­loaded to return to a neutral, or off, posi­tion.

CONCAVE ADJUSTMENT LEVER (Fig. 3)

Push the lever forward, or down, to increase the clearance between the front of the concave and the threshing cylinder. Pull the lever back to decrease the clearance.

NOTE: Complete details of concave setting and adjustments are given in "Operation" section.

IMPORTANT: On Combines with spike tooth cylinders, a stop bolt is located in the index to prevent the lever from being moved all the way back. This is to prevent interference between the cylinder and concave teeth. This bolt must NOT be re­moved.

CYLINDER SPEED CONTROL (Fig. 3)

Turn the crank counterclockwise to increase the threshing cylinder speed. Turn crank rearward to decrease the speed.

NOTE 1: The threshing drive MUST be engaged and operating before cylinder speed can be changed.

NOTE 2: On Combines with double­range gearboxes (Factory Option or Accessory) the low and high speed ranges are selected by a lever at the cylinder drive gearbox. See "Opera­tion" section under heading "Cylin­der Drive".

CYLINDER SPEED INDICATOR (Fig. 1)

I ndicates the speed of the thresh­ing cylinder.

THRESHING DRIVE CONTROL (Fig. 3)

Push the lever forward to engage the threshing drive, making sure it is pushed all the way so that it locks over­center. Pull lever back to disengage the drive.

GRAIN TANK UNLOADING CONTROL (Fig. 3)

The one control has two separate functions, as indicated in Fig. 3.

TWIST the control to the left to swing the unloading pipe out to the un-loading position. Twist the control to the

right to swing the spout to the transport position.

PUSH down on control to engage the unloading drive, and pull up to dis­engage the drive.

NOTE: The unloading pipe should be in unloading position before engag­ing unloading drive.

AUTOMATIC TABLE HEIGHT CONTROL (Factory Option/Accessory)

When this control is installed, the following details are applicable:

The automatic height control has an operating range (knife to ground clearance) of approximately 2 to 6 inches.

To set the control, push the table height control lever, Fig. 1, all the way forward until it is locked in the detent position.

Turn automatic height control wheel on side of console, Fig. 2, to raise or lower the table to the desired operating height. This setting will be automatically maintained by the control.

During operation, should it be nec­essary to raise the table quickly, for example, to avoid an obstruction in the field, pull the control lever out of detent and then back to raise the table normal­ly. When the obstruction has been passed, push lever forward and into de­tent and table will return to the original automatic setting.

To return table to normal hydraulic operation, pull hydraulic control lever out of detent position.
