I purchased a sod installation attachment for my t190 from my bobcat dealer. The machine works excellent except that it eats through the tubes that the sod is on. The tubes are made out of a thick cardboard. The sod rolls are about 36 inches wide. The attachment uses the hydraulics to clamp on to the ends of the rolls. Approxmately 90% of the rolls get torn up and it tears the edges of the sod on some of the rolls. Are there any special tricks or things that i could use to get this to stop from happening? Thanks in advanced.
