7116 attachments


Recommended Posts

More basic questions: 7116 6sp with the mower deck working fine, trying to add the tiller. I have the rear lift & cable. Is the 2 pulley idler setup needed with the 6 sp?

Can they be operated independently without removing belts?

What engages the rear PTO?

Thanks for any info,  Dave

Yes, the tiller idlers are required; if you purchase a tiller, make sure you get the idler setup with it.  A belt is usually with them, but the cost of a new belt isn't too bad.  Not so with the idlers.

There is no rear PTO, the tiller runs off the the mid-PTO (Cone Clutch), same as the mower deck.  The tiller belt uses the larger width groove.

No since they both are driven by the mid-PTO on the later model RBTs (those with cone clutches).  Most folks remove the deck when tilling.  

The "newest" tillers come with a spring loaded idler pulley on the tiller to keep the belt tensioned:



The early RBT tractors had tillers that had a built in clutch (no cone clutch):



There was a hanging PTO to drive the deck and a plain pulley attached to the BGB shaft to drive the tiller:


(3310H tractor)

With this setup, you could operate the deck and tiller independently without removing the belts. 

And there's no problem using an "early" RBT tiller with built in clutch on your tractor - normally you just keep the manual clutch on the tiller engaged.

Great info. Can I post some pics of the choices I have available?  Kind of promised Mrs. that THIS tractor would the one that would make her garden better.

Running a little short of time.

Redundant, I know, sorry.  Getting the stink-eye squared.
