[QUOTE="mclaen, post: 110640, member: 15472"] I would fix the variable speed. Having the option of speeding up and slowing down the ground speed may not seem like much...until you can't do it anymore. There are several problems with these drives but most can be fixed with seals, O-rings, and the bearings on the Roto-coupling. Another BIG issue with these is that the large snap ring groove at the end of the large sheave that holds the entire variable speed hydraulic mechanism in place wears out and won't hold a snap ring anymore. This was once the death sentence for that NLA sheave but there is now a simple fix for this that eliminates that snap ring/worn groove issue completely. I've got two 600 machines which are identical to the 610's except for the motor and have had to fixed the sheave on one machine but this part is still good on the other. The fix is about $100 at the machine shop and is a permanent repair that can be still taken apart if seals are needed in the future again. [/QUOTE]
