Well, I'm in from mowing, got about 1/2 done and the mower deck threw the belt (when I hit a stick).

This has happened a number of times sense last summer when I started using Bolens mowers, on both the Diesel G152 and the GTX 20.

 

Anybody have a fix for this?

We have a wooded yard so the sticks aren't going away.

 

Now I know why the belt guards are off/missing from both decks.

 

Dan

 

ps, the JD deck never had this problem.

Couple questions do you have the right tension spring, belt and idlers on the decks?

Are your nylon bushings worn causing the idlers to run tilted?

Unknown for both decks, they are both as I received them.

"Couple questions do you have the right tension spring, belt and idlers on the decks?"

 

Unknown on the GTX - need to check. 

Possibly on the G152 - these are loose and the deck needs rebuilding.

"Are your nylon bushings worn causing the idlers to run tilted?"

 

I notice that both of these have significantly less belt tension/spring force than the old JD had, so if the hubs on the GTX are tight, I may try an additional/stiffer spring to see if that helps.

The deck on my GTX 18 was throwing belts last year.  found the belt was worn and both idler pulleys were bad.  One pulley the bearing was nearly seized and would get very hot then through the belt.  the other pulley bearing was very notchy feeling.  I replaced both idlers and installed a new belt and have had no problem since.  Just make sure that you install the idlers the correct way.  If upside down the belt will ride on the upper lip of the pulley and you'll see a wear mark within just a minute or two of use. 

 

Brian (Bolens 1000) sells the pulleys and I believe that's where I got the belt from as well.

Bolens 1000 may have called it -

 

the idler bushing on the GTX is loose and the pulley/arm flops around. Don't have any good pics of it.

 

Here is a pic of the G152, these idlers are loose.

 

I'll pull apart the GTX and get some bushings and belt on order.

Out of curiosity ,,, Is there a proper tension that can be measured..???  I know my springs are about as old as the deck.. Would new springs be a good idea now and then.??                          Thanks   sodi.

I dont know if theres a set tension you can measure but I will say the springs do lose their strength over time especially if they are rusty.

I usually just put on a new spring when I fix up a deck if the spring looks questionable , most of these decks probably only had one or two new springs installed in a 40 year period and thats alot of wear and tear

Ditto ^^^ The easiest way to tell if the idler spring needs replaced is by removing the tension off of it by removing the belt. The spring should fully retract to its original coiled state. If it remains even slightly stretched it needs replaced. You should not be able to see any gaps between the coils.
