Hello everyone… I'm almost afraid to ask this question because I know I'm not going to like the answer. I have a 643 that the motor died in. I pulled the motor out to replace it with another one. I pushed the skidsteer around to the garage in back of my house and then moved it several more times with the motor removed. At first the tires just skidded but the second or third time I moved it they rolled ok. I put the new motor back in and all the hydraulics worked OK except the machine won't move forward or backwards. When you move the sticks, the tires act like they want to move but won't. Everything else seems normal. I let it run for about 1 hour and it never would move. Did I destroy something by pushing this skidsteer around? Thanks for any suggestions.
