Transmission Prob.on Kgro riding mower

I have a Kgro (When K-Mart sold these),Riding mower, 18HP, Briggs and Straton engine,(model 422707, type 152901, Code 9411095A)

When I try to go forward or backward with engine running, it acts like trans is locked up and if I stop and the shift Trans. again it will move forward and/or backward a short distance.

IF the engine is OFF and I slip shifter to Neutral and gently push on back of mower to move it forward, it starts to roll and then I feel it lock and not move. If I pull it backwards, it will loosen up and then I can push it forward a short distance and then it repeats locking up(transmission).
AnY one have ideas as to what is wrong? Is the transmission dead or dieing?/
Thanks in advance.

If it has the rotating disc brake it may be frozen to the pads. If you lift the rear wheels both off ground at same time, put in neutral and rotate 1 wheel forward . If other goes backward then it's likely the brake as above.

You may also have the drive belt off a pulley and it is wedging itself tight somewhere in its travel. when you push it backwards, it might be unwedging, but rewedges itself tight again when you go forward.

If it is the brake pad sticking

....can you spray wd40 or something similar on it to unstick it or
does it have to be disassembled?

I wouldn't use WD40 near the belts or brake pads unless you are going to replace them plus clean off the leftover WD40 from ALL the pullies and brake rotors.

well can you spray anything to loosen

these pads up? Or do you have to take it all apart?
