I was so happy that I found a SG30 for my MT55 when I saw their add. However, it turned out to be a very bad experience. Before you deal with Bobcat of Rockford, think again! If you want to know more about it, let me know. I found this SG30 stump grinder attachment for Bobcat MT50 series (MT55, MT52 and MT50) on the internet advertised by Bobcat of Rockford IL as a 2005 model in working condition for $2500. I then contacted the dealership and confirmed that it's indeed in working condition. We agreed to schedule the pickup day at March 25th, 2013. I drove 8 hours and arrived at the dealership on the 25th to pick up the unit after making $2500 cash payment. The sales person picked up the attachment with a larger Bobcat trying to load on my truck. Clearly they did not have a compatible Bobcat (MT50 series) to test run the attachment and load it. As a result of that, he cannot properly secure the attachment to the larger Bobcat, only with the right side attached while transporting the attachment from where it was stored to my truck. After I got home the next day, I immediately unloaded the attachment, started my MT55 Bobcat and try to attach and test run it. First thing I noticed is that the mounting plate (the frame) on the attachment is twisted and will not fit on my "bob tach". I measured the surface of both the stump grinder attachment and my bob tach with a straight edge and confirmed that the twisting or distortion is indeed on the attachment not on my bob tach. Furthermore, the control system which let the grinder head swing up and down, right to right does not work. The grinding wheel does rotate as expected. I immediately contacted Brett (the sales person at the dealership) and informed him of the issues. After working with their mechanics over the phone, I did get the control system work (about 4 hours of work). However, the twisted frame can only be corrected by a machine shop with the proper equipment. I got a quote from a local industrial clock shop for $375 to fix the problem. When I talked to the service manager at the dealership (Greg), He agreed that it is a reasonable price for the job. He then transferred to back to the sales person Brett to get permission for the work. I asked for $500 refund to cover the repair cost and the compromised condition of the attachment. Brett said that he needs to talk to the owner about it. Later he informed me that the owner does not want to pay for anything. At the time of the transaction, I was asked to sign some paper that this attachment does not carry any warranty. I should've questioned that, however did not out of my ignorance. I understand that since the unit is marketed as a functioning unit, the dealership should be responsible to bring it to a working condition before the transition. Obviously they did not do that. In our email communication, Brett did say "Had I known I would have had that taken care of before you took it"
