Which Tooth Bar should I get for digging into topsoil piles and clearing??

[3gunr]

I have both types of toothbars on three different tractors and i can say without a doubt that they help immensely with digging i would give my pirahna a slight edge over the other two standard bars

I had a 32 hp Bobcat skidsteer that came with both a flat front and toothed bucket. I could do so much more with the toothed bucket. It was like having 20% more power and traction. I also preferred it for leveling (especially if there was sod and roots in the dirt). With the bucket tipped down the teeth acted like scarifiers. With the bucket tipped level it smoothed nicely. I never put the smooth bucket back on.
