Big thanks to this site Sears reartine tiller
After researching the Sears tiller on this forum I decided to not buy my next tiller from Sears becase of the transmission problems. But early last summer I noticed the top of the line reverse tine tiller at Sears tha was normally $875 (ridiculous) was marked down to $400. I purchased the tiller but based on the info here I got the 3 yr service agreement. Well, after no more than 10 hrs of work the big dude locked up. Called the service guy who came out and said the transmission is out.
The tiller is really powerfull and heavy but the transmission is a POS. Why put 7 1/2 hp and all that torque on such a flimsy gearbox? This has got to be happening all over the country for the past few years but they continue to sell these units.
Again, thanks to this site I'm protected for 3 years. If you see one of these for sale cheap you'll know why. Don't be like me, but run away no matter how cheap the price is.
