J&M 620
Questions to be asked to identify the correct scale variation....
1. What does the hitch area look like?...
-Is it welded directly to the "A-Frame" of the hitch area?
-Does it have a sleeve welded directly into the "A-Frame and swivel?"
-Does it have an end cap secured with six bolts which provides a "bolt on sleeve" for a swivel hitch?
2. Does the grain cart have large "metric" floater tires?
3. What year is the Grain Cart?
-If you can not determine what year your grain cart is, refer to the pictures of the hitch below, which will provide an indicator of age.
There are three variations of the J&M 620 Grain Cart Scale system. The older variant of the J&M 620 requires welding of a sleeve within the hitch area, while the current and newer variant is completely bolt on. Special attention must be paid attention to regarding hitch identification as related to the variation of scale kit needed.
