The TD3418 features an over-center hydraulic folding design, so when changing from operating to transport position there is no need to leave the tractor seat.

The transport wheels on the TD3427 come equipped with a spring suspension system inside the housing which forces the cart to be raised once the weight of the rotors are removed during unfolding. The additional clearance created by this suspension system helps the tedder float over small surface changes.

Finger joints

These joints reduce the number of moving parts and wear points to provide a more direct transition of power for longer life and improved performance. When the hinge is folded up, the fingers are still in contact to maintain proper alignment; then, when the fingers fold down, they lock into place.

 

The finger joints are supported by sealed bearings to reduce wear and vibration. This results in longer machine life, reduced downtime, and a more consistent delivery of torque to the outer rotors.

The tine pitch height can be adjusted hydraulically inside the cab using the handle on the tedder, so the operator never needs to leave the seat once the tine pitch height has been set. This allows for quick customization to mowed hay height in different fields, as well as on-the-go compensation for terrain changes such as terraces.

The TD3427 Tedder is equipped with a cart that the rotors fold onto for field-to-field transport. On the cart are larger transport wheels to provide greater stability when traveling down the road. These wheels come with a hands-free locking mechanism that automatically locks the wheels in a straight, forward position when the rotors are folded in the transport position.

 

When the transport tires are locked in a straight position, it allows for substantially easier backing up of the machine and provides greater stability when traveling down the road at higher speeds.

I felt like I had been doing business with Martin Tractor for years even though it was my first interaction with them.
