Puller Tools Available For 3-Point Hitch Draft Sensing Pins{7120,5700}

Usage:

Challenger 35 (8DN, 8RD, ADK),
Challenger 45 (1DR, ABF, 3BK),
Challenger 55 (7DM, 6NN, AEN) Agricultural Tractors

The pins connecting the draft arms to the tractor can be very difficult to remove. The impact from driving the pins out can effect the electronics of the pin. Therefore, a puller tool should be used to remove the pin.

There are two tools available to remove the draft sensing pins. Both tools can be used on any gauge tractor. FT-2635 Draft Pin Remover is recommended for heavy duty use and is a more permanent tool. FT-2647 Draft Pin Remover is recommended for light duty use and may be fabricated on the job site.

Both tools can be used on all Challenger Rowcrop Agricultural Tractors. Illustration 1 shows the FT-2635 Draft Pin Remover and Illustration 2 shows the FT-2647 Draft Pin Remover.
