SOURCE: TB70ss clutch

Check to see if there is any material collected around the base of the head, around the tube that provides the energy to spin. It may cause the power to be diminished a great deal, so that must be cleaned away thoroughly. Check to see if you can spin the head freely by your hand, without the motor being on. If not, it may need lubrication down the indide of the power shaft. A light grease would do that, or even a heavy oil poured down the shaft, but not too much.

SOURCE: TB70ss Trimmer runs but does not turn the string

Remove the angle drive gearbox near the string head and spin it to see if everything is moving properly. You may have stripped the gears out of it.

I replaced drive belt on troybilt mustang rzt shortly after electric pto clutch stopped engaging

Moist likely you failed to reinstall PTO clutch correctly as it sound the anti-rotation device wasn't installed. When you started the engine it would spun pulling the wiring apart. Hopefully just connector came part; otherwise, you might need to purchase a new PTO clutch assembly.

I need to replace the transmission drive belt and need instructions

There's actually a Troy-Bilt Pony riding lawn mower as well.  If yours is like ours, a model 13AN77TG766 [URL:], it doesn't actually have gears but rather a variable-speed pulley.  The lever on the dashboard actually controls how high the brake pedal will go, while the brake pedal controls the position of the variable-speed pulley, which controls the effective gearing ratio.  That's how it can go at any speed with the engine still going at the same rate and without having to disengage a clutch.

So perhaps your mower is engaging the parking brake too early (page 17 of our manual).  The other thing I can think of is grass in the variable-speed pulley.  To check that, remove the spark plug and the battery (7/16-inch socket).  Then move the shift lever through its full range and check the shaft of the variable-speed pulley (part 63 on page 34) for debris, both above and below the loose plate thingy.  (You should be able to turn it quite easily if you put the forward/reverse lever in neutral.)

Hope that helps!

My Troybilt Snow Blower wheels have locked up

Just found the same problem with mine.  The bearing on the gear shaft is frozen.  To replace these, follow the instructions in the manual to replace the friction wheel, then tap out the bearings in the side of the case, you'll probably find one frozen up.  As long as you're there, might as well put in a new friction wheel.  Mine is looking pretty worn after fighting the bearings all winter.

Starter rope on Troybilt TB575SS

try removing the starter housing, inside will be a large white or black wheel, visually inspect to make sure the componets are not damaged and that nothing jamming it. try using a lithium spray grease to lubricate the componets. if it still doesn't work the inner coil is probably damaged or came off track. it is very difficult to fix or replace this coil. i suggest taking to your nearest service center but if you would like to try it yourself, let me know and i will give you further instructions.
