I know TSC has the TG-48 and the 48-xb. They are selling the TG-48 for $1136 and the XB was around $1250 i believe.
Specs of my tractor (JD 2210) match the 48-XB, but I just don't like the idea of one 48" tiller weighing 600 lbs and the other weighing 425 lbs. In other words, I'd prefer the heavier duty if possible.
The TG-48 says the min PTO HP required is 20 HP. The 2210 has about 18 PTO HP. I've read others have used similar tillers and the 2210 has not had a problem.
I'm hoping to get one this weekend.
