Tiller How to adjest slip clutch on tiller

[greg_g]

Wow. I know that little Yanmar engine is stout, but LandPride recommends 17-25 hp for the 34" to 58" RTA-10 series (http://www.landpride.com/lp/products/rt_main.html). I take that to mean at least 17 PTO hp for the 34" and 25 for the 58". A little doodling on the scratch pad says that the 50 incher needs about 21.5 PTO hp. Plus, the 385 pound RTA10-50 represents nearly 30% of your tractor weight. What do you plan to use for front ballast?

The next problem you're facing is the PTO shaft itself. Since it's specified for use on 20-55 PTO hp tractors, the minimum spring setting (28.5mm) is too tight for your 2210. When the spring tension is too tight, the clutch doesn't slip soon enough. You'd be better off with a shear bolt.

But if you're willing to experiment, the spring tension scale is 1/4mm per 5hp. That means (theoretically) 28.75mm would be the setting for 15 PTO hp. Using the doodle pad again, your 17.7 calculates out to 28.615mm. If you don't have a metric caliper, that's an overall spring length of 1.267 inches.

Considering that a spader will go down 12" to 14", depending on the machine, in one pass as compared to a tiller that does almost less than half that with multiple passes, it is entertainment indeed to consider that such a simple procedure works. Of course the fact that a spader will do that in extreme conditions such as hard-baked soil or waterlogged soil unlike a tiller adds a bit more mirth.

I adjusted a slip clutch on a grain auger one time with a stick welder but I don't recommend you doing the same.

Darrin -

Somehow, I'm missing your point. If the slip clutch needs to slip at a given torque to protect the drivetrain, what difference does it make what is causing that torque?

 

[Darren]

It dosn't make a difference. The point is that by using a clutch that's too tight, you run the risk of damage. By adjusting the clutch so that it's warm to the touch (when stopped of course) you know the clutch is operating and not adjusted too tight to guard the driveline.

In other words you're better off having a clutch adjusted loose than overly tight. If it's too loose, it will be too hot to touch unless the attachment is jammed by something with the pto running.
