I just bought this 721 and the cab on this thing is very heavy and pretty much impossible for me to pull back by myself. I hooked up the ATV winch to it and pulled it back but is there another way to pull it back so I can see the hydraulics under it? And how do you keep it from going too far in case you do? I put a steel bar across it in front to prevent it from going too far but is there another way t hold it there? I'm guessing I'm missing some stuff on it? The manual shows nothing on how to move it
