How standard is a category 1 3ph?

[miloman]

Hi, we (in Holland) bought an (imported) JD 2305 (23 hp) that has a category 1 3ph. I bought a Geo tiller (italian) TL115, also category 1, but I cannot get it to fit nicely on the 2 lower arms of the hitch. Reason is that the TL115 distance for the arms is aprox. 50cm, while normally (on my forntier equip.) the distance is aprx. 70 cm. Because of the 50cm I cannot firmly secure the 2 lower arms, and thus the tiller can move pretty freely from left to right. It this normal, or is there another trick to attach the tiller to the lower arms? For the rest no issues: the top arm will fit, and the PTO turns the blades.

I don't know for sure about the 2305, but many sub-compact tractors don't implement a true cat-1 hitch. They call it "limited cat-1". Usually, the problem is that there isn't as much lift height, so implements like augers may not lift high enough to clear the ground. It sounds like the problem you're having is that the implement is too narrow, and you can't hook up your anti-sway mechanism properly. Is that right?

Thanks for your fast reply! That's exactly the problem. I can (just) mount it, moving the the lower arms inwards, but the anti-sway mechanism are turned in all the way, but still the tiller moves to much (I think). I very new to this tractor business (but love it ;-), so any help greatly appreciated!
I will contact our JD dealer tomorrow as well, to see if he has a solution.
I figured I need to put a bar (the one that you put on the lower bars) through the holes of the tiller, so I can attach the lower bars at the normal length, but some handles on the tiller are blocking the attachment of the lower bars. I could probably remove the handles, and use some spaces, in order to be able to mount it more 'solid'.

Do the tiller's lower pins point toward the center of the implement, or away from the center? If they point toward the center, you may be able to reverse them (so they point outwards).
As far as 3PH standardization...many older implements follow no particular standard. There is an ANSI standard (forgot the number), but few manfacturers gave it much heed until the advent of quick hitches.
As you're in Europe, your implement will probably conform to some kind of ISO, EN or DIN specification...

Both on the left and right side are 2 plates with a pin through it. As there is a bushing between the plates, I assume the lower arms go between the plates. Also the pins are not long enough to be able to attach the arms on the outside, which would have solved my problems also (maybe have to remove the handles on the tiller as well).
Lesson learned at least is that there is no standard category 1 3ph..... Even the pin in the top bar was too wide..... Luckily the frontier pin fits.

Uhh...

Cat. 0 lower spacing is 20" (50 cm) and Cat. 1 spacing is 26" (70 cm) here in the states. It's been that way for over 50 years.

Just had a quick look on TractorData.com and the 2305 is listed as Cat 1 (limited). So, as XSKIER & josh have said, you've got a glorified Cat 0 that may be able to handle Cat 1 with some fiddling.

Xskier seems to have it figured out. It sounds like you've got a Cat 0 tiller, which is surprising. I think I would start out buying or fabricating some pins that could go outside the hitch to widen it.

Thanks bcp, I just copied your pic for future reference!
