I have an old mf50a tlb . An industrial machine of yesterday. The swing motor is the drawback of the hoe. Mine is now leaking at the top where most leak. The motor bottom shaft is slotted from what I can tell from the posts online I've seen. Can anyone tell me if the hoe is still hinged with the motor out. Should be able to cut the shaft and weld a collar on it or have a plate made in place of the toothed base plate mount. On which a spot can be fabricated to connect a ram..
