I just did a quick spreadsheet on the purchase of my L3560 in June 2020 to the price found on Kubota's website today.
The difference is $8800 greater than it was for the exact same tractor with no differences in the way its configured or the feature set of the L3560 LE as it was then or now. There have been no updates to the basic feature lineup.
It looks like a 17% increase for the 2 year time period, or 8.5% per year.
The base price increased $4219.00 (14% increase on the base model)
Additions and Options added $3977.00 (20% increase on the options)
This makes the average increase of everything 17%.
The BH92 Backhoe itself went up 17%
The sub frame Kits required for the Backhoe went up 16.8%
The LA805 Front End Loader itself went up 17%
The L2296 HD Round Back Bucket went up 17%
The Land Pride SGC 1072 Grapple went up 34.25%
Mics Hardware kits went up 16% to 18%
The way these numbers are looking, it seems like Kubota isn't making changes in cost due to specific "hard to find" and therefore more expensive items.
It doesn't look like they are just passing on the cost in those difficult to source items to specific areas or assemblies, but rather implementing a "blanket" cost increase to cover as much as possible across the board. In this case it looks like a pretty solid 17% increase over a 2 year period.
I don't see Loaders or the Backhoes, as examples, carrying a larger share of the cost increase even though the cylinders in those assemblies are (or were) very very hot commodities due to Kubota's inability to source replacements from factories that were having issues providing these materials across the globe.
The increase of 34% in the Grapple may be from some kind of discounting from the dealer I used at purchase ($2745.00), I cant verify if that was the retail price at the time in 2020, or some discounted magic they did to make the numbers work out)
Generally, that is what the automotive industry had been following (roughly a 10% annual increase) before 2021, when they kicked into high gear from COVID related supply/demand issues. I believe its gone up from there for automobiles....
