Troy Bilt 42T Won't Move

I have a Troy Bilt 42T (made in 2018) that quit moving. The engine runs, blades turn, but when I engage the gear to move in forward or reverse I saw some white smoke from the front. I checked the belts and they are intact.

i plan to check the idler pulleys.

Is there any other way to diagnose the problem?

150BT carb issue

I have a 150BT backpack blower. the last month or so it’s been really hard to start. Maybe like 25 pulls. Normally 3-4. The primer bulb makes noise like it is working, but I don’t think it is. If I remove spark plug and dump a small but of gas directly in, it starts instantly.
I thought that the primer and the fuel followed the same route through the carb. So how could it run, but the primer not push fuel through the same orifices. BTW I removed fuel line from one side and primed...

Smoke and oil from the exhaust

Just finish cleaning the carb on my B/S mod 40m777. It had been setting up for about two years. Carb cleaning went very well.

I shut it down to see if I can find the problem. Oil left in crankcase is clean but the oil being spewed out is totally black.
Any clues as where to start. I can go as far as an overhaul if necessary. But it...

John Deere - 210 - Electric PTO Belt Replacement Help!

Hello!

I have a John Deere 210, but I cannot find the manual on it. The belt that is on there now is M40223, but there is so much slack that when the PTO switch is engaged, it does not engage the belt. There is a handle on the front bumper, but I cannot turn it any further to pull that spring tighter. It's as far as it can go, because the bar that the spring is attached to cannot go any further forward. Any ideas? Is this even the correct belt?

Any help would be appreciated.

Thank you!
