I might be needing a 4X4 ATV and I will only buy one with lockers front and rear.

Yamaha is the leading manufacturer with this diff lock feature. Almost all the models offered with this have the Ultramatic transmission. I'm not anti auto transmission, but I am curious about the pulling torque, or low speed high torque output.
The Yamaha has a 2WD/4WD and diff lock selection.

Actually my Rokon is an auto Transmission and has tons of torque but it's nice to hear from others if this ultramatic has good powerful low speed pulling power and torque.
