I own a noma 10hp 29in snowblower. It works great in reverse but has an issue in all forward gears. I can lift the wheels off the ground and it goes fine but on the ground it won't go. What's the issue?

Hi,
An answer is probably dependent on the type of drive system the unit uses. It is not always easy to find parts breakdowns of Noma machines, but it is impossible to do without model numbers. Often the tag os "hidden" inside the handle bar frame. It gets put there not to hide it, but to protect it from damage. Please give it a look to see if you can find it, or you could try supplying the engine numbers; they are often covered by the electric starter switch on top of the engine.
Peace,
Clarke
