Cub Cadet 400 Tiller on a GTX2100

[Shotgun Wedding]

Just to update those who care... on my Cub 400 Tiller with the JeffinPa Sleeve Hitch to 3pt adaptor all I can say is WOW.

You've already seen this pic, but I am going to be like CAD!


Did run into a problem though, first 2 minute of running there was a clanging noise, shut it down immediately and found the center/middle shaft in the gearcase had worked itself out and the gear was now off. Ouch!

With some discussion with Joe Knight, (thanks Joe), I ripped it apart and spilt the gearcase to find a total lack of any lubrication grease at all. Like none. Also, the two bushings on the middle shaft had completely failed, and looking at some tarry, solid grease material at the bottom...this had happened awhile ago with little bits of brass lodged deep into the tarry mess.

Gearcase as is, no grease.


Bushings, note the bottom one is a new one bought from my Cub dealer in town, the other two are the old ones. One is completely torn apart, the other 95% torn apart. Nice


While I was in there, decided to replace the two main bearings and oil seals on the bottom tine shaft as well, they were fine but I don't plan on doing this again. The tine bolts were bad, wore pretty badly, and had ovaled out the holes in the shaft. Recommend to anyone who has one of these to check those bolts for wear and replace before the they oval out your shaft as well.

The middle gearcase shaft was OK-ish. These are NLA, so I took some fine emery cloth and worked it all around to smooth out where bushings damaged it a bit.



Put it all back together, filled with 10lbs of grease, new gasket and a few new bolts where some old ones were bad.

Will post some action shots. This thing rocks! Put on free-float setting on the sleeve hitch and she digs as far as I will let it! Hitch adaptor from Jeff is absolutely A1 quality work.

Sweet looking setup. For what it's worth I drilled my 1A tiller so that I can fill it with gear oil. I know it's supposed to run in grease but it was stiff when I bought it and with the oil it loosened up just by working by hand. Other reason I filled it with oil is that oil will get into the pins of the chains plus I didn't want to try to get it apart just to grease it. Yes it leaks but I can deal with the leak and I'd rather have the leak than trying to find NLA parts. Just tossing this out for you to consider.

So here is the tiller in action, sorry for the blurry pics, they were from my neighbour as I was tilling and he was in awe of the Cub Cadet awesomeness!

Check out JeffinPa hitch in action too.

Here she is set and on the up position.



Here is the down position, note how well it digs in clay. I haven't been able to work this ground more than 5 inches with a rear-tine tiller, this baby took 10 inches with a bit of a load on the engine, but still no problems. Love this thing. It will dig far enough down that soil starts pushing up on top deck! That's 12 inches! That is time to hit the UP button!



And here is finished product, smooth baby, smooth!

Man that does a nice job! I want one!

Is that shaft 3/4" ? If so, I have TG&P 4140 steel here and can make a new shaft for you.

Hey Jeff. I will measure it. That would be good to have a new one as that one was a bit scuffed. Is there anything you can't do Jeff? Everyone needs to know a master machinist!!!!!

I can't cut splines YET. I need a bigger, sturdier mill for that

The setup looks awesome! Man, that thing does till DEEP. Glad to hear you got her back up and running.

That is one impressive setup, I'd love to have one of those tillers in my shop
