Just got a Bobcat 743 with about 1500 hours. New plain bucket. Have rented other equipment in past, but I am not an experienced operator. So...I need a few tips. 1. I assume indoor parking is preferable. 2. When operating, machine for first time, it travels great at full forward, and fine on spin turns. But when I try to SLOWLY go backward (dragging bucket to level gravel) or SLOWLY forward it sometimes is smooth and sometimes herky jerky. The ground was very wet. So, is this jerking just an inexperienced operator, a design limitation, a function of the wet ground (tires spin, etc), or mechanical problem? 3. Is there any reason I shouldn't operate in mud as long as the mud isn't bad enough to bog the machine? What about puddles? I don't intend on driving into 2 feet of water, but I assume an 8 inch deep puddle is ok? 4. It seems tippy, especially when herky jerky. As long as I travel with bucket down, how difficult is it to tip one of these over? 5. Sadly, I don't have the manual. Does anyone know where I can get one? Thanks, BJ
