One of the design improvements introduced with the Ford Model
8N tractor was a provision for mounting an under axle clevis for pulling jobs. This location was a much
safer pulling point than the 3pt drawbar and Ford initially provided the 8N-803 clevis as optional equipment
on the 8N tractors. With the advent of the model NAA tractor the clevis was redesigned (NCA-803B) and a flat
drawbar (C0NN805F) and support
hanger (NCA809A) where added. The hanger bolted to the PTO housing
and supported the drawbar which was connected to th eclevis on one end and extenderd the implement attachment point further
to the rear. The drawbar could be swung from side to side allowing the towed equipment to be positioned
off center - a highly desirable feature for implements like balers and pickers. The new clevis, PTO support, and drawbar were
backwards compatible with the model 8N tractor but could not be fitted to the earlier 9N and 2N tractors because they
lacked the under axle mounting boss for the clevis.
To address this shortcoming the 9N-803B drawbar adapter and
clevis assembly has been developed to allow the retrofit of the NAA style swinging drawbar assembly to the 9N and 2N
tractors. The basic component of the adapter is a welded steel "cradle" that bolts to the bottom three
axle extension studs on either side of the differential and wraps around the underside of the differential housing providing
a mounting boss and holes suitable for attaching the NAA-803B clevis. The NAA drawbar and hanger can then be mounted
exactly the same as on the 8N tractors. The adapter can also be ordered with an optional welded clevis assembly
that works with the NAA drawbar and hanger and eliminates the need for the bolt on NAA-803B clevis altogether.
The adapter comes primed ready to paint and includes all mounting hardware needed to attach it to your tractor. A
socket head pipe plug is also provided as a replacement for the square differential drain plug used on the N-series tractor.
The socket head plug provides additional clearance for mounting the adapter and can be accessed through the drawbar
pin hole in the clevis using an Allen head socket and extension or a hex key.
