Question Statement:
Which of the following statements regarding tractor three-point hitch operation modes are CORRECT?
Options:

- (B) In draft control mode, the hydraulic system senses implement draft and raises or lowers the implement to maintain a pre-set draft force.
- (C) Draft control is especially advantageous when plowing through undulating ground with varying soil textures.
- (D) Restrained link operation relies entirely on implement gauge wheels to determine depth with no hydraulic pressure in the rockshaft cylinder.
