Good evening-I purchased a new Fastrak Super Duty 48" a couple weeks ago and the ROPS system was not installed on it. The dealer's Hustler rep had one ordered and it was ultimately delivered to my residence. I installed it today following directions verbatim. My question is: 1. After assembling the ROPS system, I torqued all hardware to specification. The left and right ROPS posts were torqued to 73 ft-lbs. Upon doing this, the outer frame (the side which the nut was attached to) dimpled the metal frame in all four places where the nuts were. Is this normal or is something not right? I utilized 2 seperate torque wrenches so i know that the torque was adjusted properly. 2. In the ROPS instructions it says to torque the lug nuts for the wheels to 118 ft.-lbs. but the manual says to torque them to 65-75 ft.-lbs. Which one of these are correct and why is there such a difference between the two specifications in the manual and the ROPS instructions?
