Ok, no joking this time. Using an automobile to pull wire is stupid and hazardous. As the poster said, a failed clutch is all too common in using one, and also there is no real control of the pull. A Greenlee tugger or equal should be planned for and purchased by any electrical contractor who opens a commercial shop and plans to be in for the long haul. It is as necessary as a work van or truck to the business. The tuggers and the proper pulling rope, sheaves, etc. can be rented also. For easy pulls, I am all for rigs like the one in the picture, but when people start hooking up pull rope to the back bumper of a pickup, that is when other people can and do get injured. If you have to , try using a hydralic method instead, like tying to the forks of a forklift, and slow steady lifting the rope up out of the conduit.
