    Default KK Tiller Questions / Observations

    Got my 60" KK tiller hooked up to the B7800. The tiller is built like a tank. Couple of questions...

    When the pto is running but the tiller it high up on the 3ph, there's a clunking from the shaft that goes away as it's lowered. I'm assuming that it's not good and that the shaft should not be turning at such a sharp angle. Just what is making that clunking sound and is something getting chewed up?

    Slip clutch - I set the nuts so that the tip of the bolt coming through would be flush with the nut. Well, I had lots of clutch slippage set like this so I changed so 1 thread could be felt protruding from the nut. Still some slippage. How far though the nut does anyone else have the bolts? The manual is poor on this - it says to have the nut touch the yoke - like there's no spring there. I slipped mine a lot experimenting and I could smell it. How thin does the friction disc have to be before it should be replaced (it's about 1/8" inch now) and where can I get a replacement?

    Speed - It's slow going, like inching along. Is this the speed everyone else goes? Seems like anything faster and the vibration is unreal. Perhaps those with a heavier tractor to tiller weight ratio can go faster? It does a great job inching along, but I'm tilling an acre to plant a cover crop. I ran a cultivator through it first, but I don't think it helped much.

    i don't have a KK tiller but a different brand....the tiller shouldn't be engaged when the lift arms are up. i don't know about your slip clutch. it shouldn't be slipping frequently. if i am tilling to create a seed bed i go as slow as my tractor will allow...low low gear. if i am tilling to cultivate and get rid of weeds i go a bit faster.

    I have a 60" KK tiller on a 27 HP (engine) Ford 1710.

    Clunking is due to the angle of the PTO shaft. You are raising it too high and the angle is too much for the Shaft to turn smoothly.

    When trying to break-up the ground or to get more depth the slower the better. I've got best results when going as slow as the tractor will drive at 540 RPM. My tractor has gears not hydro but gear 1 range 1 is slower than a walk. Can go faster if ground already tilled good and just want to knock the weeds down or if like results.

    The slip clutch adjustment. The way I read it is you loosen the nuts until the springs are loose. Let the clutch slip a couple of turns. Tighten the nuts until the spring contacts the surface. Tighten nut 1 & 1/2 turns. This is a starting point. You may have to tighten a little more if clutch slips to easily. I'd suggest letting the clutch cool down good after letting it slip. I think when it is hot it will slip more easy.

    I'd run the cultivator over it at least twice. One run east to west next run north to south.

    The clunk clunk clunk sound is the U-joint self destructing. Don't do that! There should be a measurement on how much gap between the plates, not how much thread is exposed on the bolt.

    You want it to slip when the engine is about to stall, and to instantly restart when you raise the 3pt.

    If the ground has never been tilled in the past 5 years and it is dry, it will be hard like cement. Plan on going over it 3 times. First time much faster than you are now, to break up the surface. Then go slower 90 degrees to the first pass. Then repeat that speed going oposite directions from the first pass. If you have a lot of grass and stuff, you should wait a week or better 2 weeks and retill to allow the organic matter to decompose. That will also allow the weed seeds to germinate and they can then be killed by tilling.

    have fun and don't get impatient!

    When I set up my slip clutch, I loosened the nuts until I could just rotate the spring. With all loosened like this, I still had to drop the tiller to the ground with the PTO engaged in order to confirm that it would slip. I then tightened 1-1/2 turns like the manual and tilled the plot with delight.

    That was a week ago last Saturday. Tonight, after reading a post in a related thread, I looked underneath the rear cover and removed the copy of the manual that was taped there.

    That's funny! I remember being surprised to find the manual taped to the underside of the rear cover as I was adjusting the skid height.

    I did the same thing. I tilled for about an hour after I got my tiller all set up. When I got back to the barn to hose it off I lifted the rear and found the manual.

    Dont lift the tiller all the way up. The angle of your PTO shaft is putting alot of strain on your u-joints and they will self destruct. Keep them full of grease.

    Slip clutch adjust like everyone else said. Loosen till spring has no compression, Let clutch slip a little to make sure it is not froze up. Tighten nuts till spring is just starting to compress then go an extra 1 & 1/2 turns. Might have to go a little more. I had to go 2 & 1/2 turns.

    Tilling is very time consuming. You want to go as slow as you can go to break up the soil. If you have hard pack ground or alot of grass on it plow it under first the till. This is how I did it this year.
    You will still have to go over it at least 2 times with the tiller to make a nice bed.

    My KK tiller does great. It's hard to go slow when you could be dragging stuff and covering ground. Take your time and you'll have seed bed ready to go in one or two passes. Watch out for the big rocks. They can kick the tailgate out pretty far!

    I used the tiller the other day to break up and smooth out a friend's riding arena. He ended up with some erosion from heavy rain and after using the FEL to reclaim the sand, we tilled it and packed it down.
