Massey Ferguson 135 vineyard or orchard model

[Thistle]

I have a massey ferguson 135 ser #9A147353 with a 3 cyl gas perkins and 12.4-24 tires. I am trying to determine if it is a Vineyard or Orchard Model.?? What is a narrow model ??I have enclosed photos. What are the features that determines which model it is . I need this info to purchase a front weight frame.. If anyone knows of the part # for this and where to get one it would be a real help. I can send additional photos . Thank you

All the 135 orchard tractors had 165 rear axles with wet brakes and wide low tires. I can't remember the tire size. They also had heavier lift arms etc.. Look at my photos. I have a split picture of the rear of a standard 135 with wide tires and a 135 orchard.
