Roper tiller 26 inch front tine Pulley/belt diagram

tensioner pulleys run on the back of the v belts
most tillers move forward by the action of the tillers bur occasionally they can be belt driven
that may be the spare pulley if you have a pulley on the axle
otherwise run the belts direct to the tillers with the tensioner pulleys running on the back
would need to know make , model and year to get a diagram of the belts

Hello, Did you notice if the tines moved when you turned the belt pulley to install the new belt? If the tines do not move when you rotate the driven pulley by hand, the worm gear might be stripped. If the tines do move when you rotate the driven pulley by hand, the belt tensioner might not be working properly. It could be as simple as an adjustment.

Hi and welcome to FixYa, I am Kelly

Here is a picture of the belts installed.

NOTE the front fwd direction drive belt / closest to the motor is installed like any other belt. The rear belt for REVERSE direction has 1/2 twist. The idler pulley presses in for foward driving and pulls out against the reverse drive belt.

This should be what you need.

Thanks for choosing FixYa,

Hello, W/D here.

The motor drives a belt, and the belt drives a pulley that causes a chain to drive the tines (blades). For the belt to drive the tines, an idler pulley has to put tension on the belt. This is moved into position by a lever that pulls the pulley into tension on the belt, and tension is maintained with a spring when the lever is locked into place.
1. Make sure that the tines will rotate with the belt off. If there is difficulty, check for debris holding the tines (roots, etc.). If necessary, remove the cap covering the chain cover inspection port, and with the machine tilted back, observe for proper operation of the chain while moving the tines by hand. Lubricate the chain according to your manual. If your chain is not working properly, disassemble down to the chain case, and inspect the chain and sprockets. Chain is radily at places like Motion Industries, WW Grangier, or a bicycle shop. Often overlooked, check that the pulley set screws are tight, and causing the shaft attached to it to actually rotate. Check the pins and locking cotter pins in the tines, make sure that they are pinned to the shaft.
2. Check the belt. An old belt can stretch to the point where it will no longer work. The "V" belt can also wear down to where insufficient friction can be applied to the driving or the driven pulleys to cause it to rotate.
3. Check the condition of the idler pulley and spring. Make sure that the lever places tension on the belt. It should be somewhat difficult to engage the idler pulley when the belt is new. You may have an adjustor on the idler that will tighten the belt.
Best regards, --W/D-- Please provide feedback for our solutions so that we may continue to improve in helping others. Thanks.

There are several possibilities:
1. the belt is old and over stretched and needs to be replaced.
2. you have a bent shaft that causes the pulley to speen crooked.
3. The pulleys are not lined up. You should be able to adjust them by loosening them and sliding them back and forth on the shaft.

To replace your tiller belt you will have to :
Take a few pictures before you get started so you know how everything goes back together.
- 1) Remove the belt guard
- 2 ) Loosen the belt pulley and remove spring, remember how this was attached.
- 3 ) Pull the belt through housing and off of the transmission pulley.
Now grab your new belt and install in reverse order.

Check belts

Check under the metal or plastic cover just behind the engine. This covers the forward and reverse belts. Your belt either broke, jumped off fthe pulley, or needs a tension adjustment.

Little grease on the shaft and some work was able to remove pulley. Found input pinion, tine sprocket and gear all missing some teeth. check with sears and these parts are no longer available. Can anyone tell me where i might find or locate replacement part i need for this tiller?
