Tpundy,
I just went on the John Deere Site and looked up the 4110 in their "Parts Catalog". There's a 47 inch Snow Blower listed under the 4110 with a seperate parts list for the Mid PTO required to drive that blower (attached) for both the 4100 and 4110. If you go on to that site you'll also find the front mounting bracket, hydraulic lift, etc., so you can identify if you have the right parts for the 4110. The only trick, to identify the length of the Universal Driveshaft listed in the attached. GOOD LUCK...........
