Thanks johnr j, I agree with your parts manual comment but I was just using that as a reference point. According to a Yale 120VX operators manual the "tow pin" is to used for towing a disabled forklift with another forklift and as a tie down point for transport, as motioned earlier. If you have disabled forklift @ 17k lbs being towed by another forklift as recommended by the MFG what's the difference if you're towing a trailer as long as the gross weight does not exceed the MFG's maximum draw bar tow spec?
