If the OP sees a front mounted snowblower or anything else that requires a mid PTO in the future, verify this tractor has a mid PTO or at least confirm the cassette gear is already installed. On some of the older models the cassette gear is not always installed at the factory making it considerable work to add later (might require splitting tractor). If the cassette gear is in place, the mid PTO is a very easy addition. Of course this assumes there is a need for a mid PTO (front mounted snowblower, mower, etc...).
In looking through an old copy (2003) of the wholegoods price list, I couldn't find any reference to a snowblower option for the L4610. There are listings for the L3010, L3410 and L3710 but nothing is documented for the larger L4x10 models.
