Just curious...how about using my trailer hitch? That should take care of the rear.
While I would completely agree that the Hi-Lift is likely the most dangerous tool in your bag, I would contend that it is also one of the most versatile. While many functions can be replaced with specialized peices of equipment, you will be hard pressed to find a single tool that will do it all like a farm jack.
The OEM jack goes much higher than I ever expected. I will use that even if it means stacking on a rock before I'll use my hi lift. The hi lift is a great tool, but surely a dangerous one, even when used properly.
