1700 Series Round Balers

The open throat design allows hay from the windrow to flow over the pickup and stuffer fingers and into the vertical bale chamber without restriction.  The vertical bale chamber is the cavity formed by the belts which assists in quick bale starting.

Variable chamber balers work by “varying” the chamber size as the bale size increases.  There are no floor rollers used with an open throat vertical feed system because floor rollers can wrap in certain conditions, or cause problems shattering leaves with dry hay.

In the dual arm system on the Model 1734 a top arm maintains belt tension while the bottom arm keeps tension on the bale.  The tension is applied to the arms through preset springs on each side of the baler. The system is balanced with the springs on both sides of the baler, reducing strain on the baler frame and making more consistent bales.

A spring initially controls the single tension arm on Models 1745, 1746 and 1756 and is in effect when the bale core is started.  As the bale starts to grow, the hydraulic density system takes over keeping consistent pressure on both the bale and belts.  The density system is balanced with a hydraulic cylinder and spring on each side of the baler.

The mechanical overfill protection provides the Model 1734 with protection from damage that could occur if an oversized bale is produced.

 The declutcher rod disengages the pickup drive when the maximum bale size has been reached.  This prevents additional crop from entering the bale chamber and forcing the bale forming belts, that are traveling in opposite directions, from contacting each other. A main drive slip clutch protects the 1745, 1746 and 1756 bale chambers.

All Massey Ferguson 1700 Series balers feature a single twine arm with dual tubes.  This applies twice as much twine as single tube systems, cutting bale tie times in half.  Also, a single arm is less complicated and has fewer moving parts than a dual arm system. Electric tie is standard on the 1745 but optional on the 1734. AutoTie is standard on the 1746 and 1756 and is an option on the 1745.

The Sure-Trac Crowned Drive Roller has a crowned drive surface resulting in longer belt life and less maintenance.  The crowns on the drive roller help keep the belts centered in the proper position; also the texture of the roller ensures that the belts stay turning even in adverse conditions.

Auto-Tie is a factory option on the Model 1745 round baler and is standard on the 1746 and 1756.  The Auto-Tie has three modes:

1. Automatic:  The twine tie will automatically start after the “Bale Full” alert sounds.  (After a 1.5 second delay, the audio alert will beep six times and then the actuator will start the tying process.)
2. Semi-Automatic:  The audio alert signals when the bale reaches a preset size.  The operator then controls when twine application starts by activating the “Cycle Start” switch.
3. Manual:  The toggle switch is used to extend or retract the twine actuator.
