Customer Question
How to tension deck...

How to tension deck belt on Craftsman ZTL 8000? I had Sears tech come out last week & replace drive belt. Since his repair, the deck belt does not engage the blades properly. I don't know if it is belt tension or electric clutch.

Mechanic's Assistant: I'll do all I can to help. How long have you been dealing with this?

Since Saturday

Mechanic's Assistant: Do you plan on doing the work yourself?

I've only mowed with it once since the repair. Yes, I plan on doing the work myself.

Mechanic's Assistant: Anything else we should know to help you best?

Nope. That's about it.

There is a spring attached to the idler pulley arm that pivots on your mower deck. This spring keeps your belt tight at all times, even when your engine is not running.

Technician: Donald, Small Engine Technician replied 2 months ago
Check to see if your belt is tight. If your belt is the correct belt, and is tight enough, then your pto clutch could be slightly slipping.

how do I know if the belt is tight enough? Is there supposed to be any slack in it?
Technician: Donald, Small Engine Technician replied 2 months ago
There should not be any slack in your belt.

The deck and deck belt worked just fine before the service tech came out last Thursday to replace drive belt.

How old is your mower?

OK How do I adjust the tension on the deck belt?
Customer reply replied 2 months ago
The mower is 5 or 6 years old
Technician: Donald, Small Engine Technician replied 2 months ago
On your deck, there is not away to adjust the tension on your belt. If your new belt is slightly slipping, it could be due to your belt being incorrect, or your pulleys could be worn.

Your spring is your tensioner.

Have you checked to see if Sears will send the technician back out?
Ask Your Own Small Engine Question
Customer reply replied 2 months ago
No. The new belt is not the problem. The new belt is the DRIVE belt, not the deck belt.
Customer reply replied 2 months ago
Also, there is nothing wrong with the deck belt.
Customer reply replied 2 months ago
No. I do not have that number.
Technician: Donald, Small Engine Technician replied 2 months ago

I apologize. I thought you initially asked how to tension your deck belt?

Ask Your Own Small Engine Question
Customer reply replied 2 months ago
I did. I cannot mow in the condition it is in. The deck seems like it is not being fully engaged when the PTO switch is engaged. You can't even tell a difference in the sound of the mower.
Technician: Donald, Small Engine Technician replied 2 months ago

I am wondering if the technician reinstalled everything correctly? You did not have this problem prior to the services being performed on your mower.

Customer reply replied 2 months ago
No sir, I did not.
Technician: Donald, Small Engine Technician replied 2 months ago

Are your blades spinning at all, after you turn your pto switch on?

Ask Your Own Small Engine Question
Technician: Donald, Small Engine Technician replied 2 months ago

I suggest that you make an appointment for Sears to double check this issue for you.
