Anyone have an idea of what size bolt would fit these threaded holes on the right rear support of my cabbed L6060? I'd like to use them for a bracket to mount a hydraulic multiplier.

It's an M10x1.25.

My MX6000 has the same threaded holes in the same location. I hope you show the hydraulic multiplier and bracket once done. (y)

Thanks for that! I'll give that a go. I'll get some pics up when completed. It's only a 1x2 multiplier, but was heavy enough, with hoses connected, to bend the bracket holding the 2 rear remotes.

I have a 2019 l6060 and have a guy making me a bracket for the summit 3x multiplier, any luck with yours? trying to find the distance center to center of the holes because I'm not by my tractor at the moment... anyone have that random data on hand? couldnt find it in messicks or the handbook.

The holes in my MX6000 are 3.94" center to center. I used a caliper to measure outside to outside, then measured the hole diameter and subtracted that from the first measurement.

My bracket is already on the tractor, but measuring hex bolt center to center is ~3.84". Got similar measurement on a scrap piece(due to a welding screw-up) that fit on the tractor when I did a test connection.
It's almost put together. Pic's to follow when setup complete.

I checked the spacing again this morning using two different approaches. First I measured outside to outside of the bolt heads and subtracted the diameter of the bolt head. Then I measured outside to outside of the bolt threads and subtracted the diameter of the thread.

1st method = 3.92"
2nd method = 3.91"

My first attempt at measuring the hole spacing as described in an earlier post was 3.94" so I have three measurements obtained three different ways with an error of +/- 0.015". Not doubting that the L6060 is different, just providing one data point obtained from one MX6000.

Honestly, the part looks exactly the same as on my L6060. Were talking about variances of a few hundredths of an inch. Most likely due to slight variations on how the tractor's mounting plate was applied. When I drilled my plate to attach, I drilled slightly larger holes than 10 mm in order to allow for slight variations as well as minor adjustments for measurements. I should have pictures up this week. Just making some fine adjustment on the bracket.

Our measurements differ by around 0.100" which is a tenth and more than "a few hundredths". I would expect a more tightly controlled spacing than that, but as you say, drilling larger holes in the bracket is the work around. When I make a bracket for mine I'll use the 3.915" spacing and size the holes appropriately.

Looking forward to seeing your finished install. I'm going to add a 4-way diverter to the M6060 this spring.

Sure, just found my original "back of the envelope" calculations and I got 3.85". I think the take-home message is to do your own measurements and allow for some "wiggle room" by drilling the holes in your bracket a bit larger than the bolt size. Everything seems to work on my build. I'll post some pics tomorrow.

Had a buddy machining a solid piece of alum and havent been able to put it up to the tractor yet but hoping everything lines up

I would guess it's an even 100mm (3.937) spacing on a metric tractor. Grab a metric ruler.

That sounds impressive. Hope to see some pics when you have it installed!

Pretty good guess given that I measured the spacing to be 3.91", 3.92" and 3.94" using three different methods. 100mm +/- 0.5mm would be reasonable for this part.

I used a Mitutoyo digital caliper which has inch or millimeter options for the display, and when it's time to make a bracket for the M6060 and MX6000 I'll use the same caliper (or two of my other Mitutoyo calipers) to mark the hole locations correctly. In other works, no metric ruler required. 😂

Metric is soo easy to work with.

Agreed. I grew up using the metric system but this is the good 'ol US of A where imperial rules. It's funny to me how some countries end up keeping some imperial units while mostly using the metric system. For example, the UK switched to litres for fuel but kept all of the highway signs in miles.

The company I work for uses some vendors overseas and they want drawings with metric units. I include both imperial and metric for those drawings since the same part might be made here and overseas.

This is what I was going to say. This is a metric machine so think how a designer would dimension the hole pattern in millimeters. 100mm makes a lot of sense compared to something like 99.6mm.

You've likely resolved your problem, but I'd recommend one of these type thread checkers:

I used one of these thread gauges for a long time. They get the job done but suck compared to the above.

Sure, thanks! On the one hand, cheaper to just asked some of the very knowledgeable people on this site regarding anything Kubota. On the other hand, looks like a great addition to any toolbox, I'll likely add one to mine.
