Cat 1 3PH specs

[oldnslo]

Hi all,
I found the dimensional specifications ISO 730-1 for tractors showing lowered lift Arm max height of 200 mm (7 7/8"). On my BX they are 9 1/2 - 10 1/2" depending of if the FEL is on the ground or not.

Does anyone have the specs for placement of the attachement point for the implements?

I am trying to decide if I need to modify my BX lift arms or my Box Blade. My concern is, if I rent or purchase other implements like rototiller, ratchet rake, snow blower will these work on my tractor or will the lift arms be to high.

For those of you that have multiple implements could you measure the distance from the ground to the lower link attachement points.

TIA

Roy

There are post on TBN with links to the exact 3PH measurements for all Category hitches. In fact, I posted one somewhere but can't find it now.

Doing a search might help you find the information.

GW,
by doing searches is how I found the specs for the tractor. I could not find any specs for the implements though.

thanks

Yeah.....but what you found were ISO (International Standards Organization) numbers. That's why they're metric. Not all tractors - especially those sold in America - conform to international specs. And implements,.....jeez - don't get us started. There are folks with Quick Hitches that are cursing the various implement manufacturers for NOT having any consistent standards.

But I'm wondering if you're not making an issue where none exists. You should be able to vary the lift arm height with the vertical links. i understand that some tractors have only one side that is adjustable, but that obstacle is easily overcome. Replace the fixed length vertical link with an adjustable identical to its mate. Both my current tractors on the other hand, have a PAIR of adjustable vertical links.

someone helped me with this so I am paying it foward

Greg,
I am trying to determine if my BB is made to Cat 1 spec or if it could also be part of the problem. Buying the parts to make both links adjustable from a dealer is expensive. Not sure about Kubota but for a JD 2305 which is a comparable class tractor these parts are $240.

thanks, this lets me know my BB is to Cat 1 specs so time to get to a machine shop and see what it will cost to have a solid 3/4-10 turnbuckle made.

again thanks to all

What you're askin' is not really a function of the tractor. What makes implements Cat1/2/3 is pretty much limited to the lift pin diameter and spacing, and the toplink diameter. In case the diagrams were not clear, Cat 1 implement lift pins are always 7/8" diameter, spaced typically 27" apart. Cat 2 lift pins are always 1-1/8" diameter, spaced typically 32" apart. Cat 1 toplink holes will be 3/4" diameter, Cat 2 are 1" diameter. The vertical distance between pins however, is somewhat less consistent. But some implements give you optional lower pin placement locations. Cat 1 construction is also typically less sturdy than Cat 2, which is simply to cope with the extra power of Cat 2 tractors.

So directly to your original question, I'd say that - if modifications are to be made - they should be to the implement rather than the tractor.

The height from the ground will be all over the place, since some implements are ground engaging and some ride above. Generally speaking if you have an implement that runs eight inches deep when using it the pins will appear to be about eightteen inches high when sitting on top of the ground. Some are much higher such as a tiller and some are lower such as a harrow where the draft point requires the lower point to pull from.

My three tractors vary from seven to eight inches off the ground for the lower position. When building or modifying implements I allow some extra distance in the implements to allow them to follow ground contours better.

With high draft implements the arms will want to pull straight out from the lower link attachment points on your tractor, so this needs to be considered too.

Do you have the other part of this chart - with the "B" dimension?
