I have a 68 4020 and haven't ordered an operators manual yet.

The tractor has a Powershift Tranny which I love but I can seem to find the diff lock. The repair manual discusses one but Alas I cannot find it. I can kick power side to side with the brakes but never have both wheels turning.

Anyone have an idea?

Diff lock was an option on 4020's >SN 91000-up. If equipped with diff lock the engagement pedal will be at RH rear of operators platform. After engagement pressing either brake pedal will disengage.
