L6060 hydraulic system is completely different than L5030. That's that. No comparison.
Kubota dealers aren't cat dealers. Nor are they Deere dealers (usually). Big name manufacturers don't like dealers being multi-line; little dealer I worked for was a prime example. We sold Deere from 1982 through 2004. In 1992 they picked up Kubota (I was assembling NEW B7100's....) In 03, Deere reps came in (like they did every month) and told the boss/owner that Deere wanted the dealer to carry Deere only, and that they would penalize the dealer for being multi-line. Dealer sold deere off and focused on Kubota which was a very good move as Deere went more mass market. Then in the mid 20-teens, Kubota pulled the same stuff. Trying to force the dealer to give up the Yamaha and Kawasaki stuff since it was a competitive brand (SxS's), and that the kubota dealer was to also carry construction and hay equipment. Boss (same boss from 1982 through 2018) said no. He was in his 70's and it was time, so he sold the dealer. I (we) stayed but I got out in 2020 as the new owners hired a GM that doesn't really work well with employees.
Anyway, most of your deere and now kubota dealer techs that were/are worth a flip, have left. There's a few good ones still hangin in there. Problem is cost. Stuff costs a LOT more than it did, and dealers are stuck in the 1990's when $20/hr was good money. $20/hr is peanuts now. Remember it costs us techs to drive to work, buy tools, lunch, dinner, breakfast, and it costs a LOT more than it used to. So if Kubota boss pays me $25/hr and it costs me $17/hr for basic necessities (food shelter water), then there's not much left for anything else, such as health insurance, car payments, and what have you. Thus, the old/good techs found work elsewhere that pays better, has better working conditions and/or better management, and has better benefits, and the new ones are still green. If you asked a green tech how to set up the draft control, chances are that he (or she) don't even know what draft control does, much less how to set it all up. For that matter a lot of seasoned techs don't even know. Frankly, I'm green with draft control and I had 29 years to learn it. The focus in my last few years was construction equipment and hay equipment. They pushed that stuff heavily. I had to go to school 4 times in 2020 to "learn" it--and it was grueling. I don't mind traveling but don't come to me the day before I gotta be there and say "oh by the way you have to be in Kansas City at 0700 tomorrow morning for a 6 day class" (I'm 500 miles from KC). There is a lot More money in hay and conttruction than Grand L series. Don't think so? Sales guys...had two of them, #1 focused on CUT's and mowers and powersports. #2 focused on construction and hay. #1 salesman was making $160,000 a year doing mowers and cut's. #2 was doing a quarter million+. Remembering they work on commission so the more money they get out of the equipment the more money they make (profit based). The focus on money hurts the entire lineup and it hurts the entire dealer but since money is what makes the dealer stay in business, that's what they kinda have to do. And remember stuff costs a lot more than it used to including for the dealer. And now lets add this too-social media has blown up in the last 10 years so now when one person has a bad experience (they didn't have a spark plug in stock, or whatever) they turn to social mediato blast the dealer and often the story gets dramatized, or turned a little bit to mean a little more to the customer than it originally did. Now the entire world can see that and it helps sway a few more customers than it used to when word of mouth while eating at the local diner was the only way people knew stuff.
what botered me was the fact that the sales guys, when a customer walked in and wanted to buy a push mower, they both turn up their noses because they knew the customer didn't want to spend $150,000 on equipment to cut hay or dig the dirt. So they just shunned the small sale customers. What they had forgotten was how the little homeowner who wants a $1500 pushmower had a great experience in, say, 2000--and decided that once he got a little money he was going to buy a farm/ranch. Then when that happened, he was starting to age and needed a bigger or better tractor, or one with a cab so the yellowjackets weren't tearing him up. Oh, and don't forget he also needed a SxS to get from the house to the barn or house to mailbox. He didn't forget that lowly pushmower sale. But the guy who walks in wanting a generator that brings about $10 to the sales guys, when the salesman just walks off when he realizes the customer ain't spending more than $1000, that customer ain't an idiot-they remember that too, and they also remember that when it comes time to buy a bigger tractor with a cab so that the yellowjackets can't sting through the cab glass....I did some limited sales and I saw it VERY often. Salespeople can get real greedy and real stuck up. That money will get to you. And sales vs service? If I had to go back to 1992 when I got into tractor repair, I'd have gotten more into sales since that's where the money is. In 2020 when I left my salary was $52,000. Same year, #2 sales guy was $257,000. I worked out in the heat 5 months out of the year, spend 4 weeks in training halfway across the country (and got zero commission pay for it...), working under equipment that weighs up to 15,000 lbs, and is covered in cow/horse poo and no telling what else. Or maybe an RTV that has needles and whatever else poking you as you're fumbling around trying to get a nut on the back of a bolt (has happened-I went to the doctor a few times afterwards because the owner of the equipment was diabetic and had STD). Cold for 2 1/2 months (below freezing quite a bit), have to do field work, no shade, 115 deg air temp, heat index of 130 or so, around customers that couldn't care less about ME (the tech), just that his tractor gets fixed, meanwhile Mr. Salesman sits in a cubicle at 72 degrees year round complaining because it's too hot outside to go greet a customer that doesn't want to spend a hundred grand on a skid-steer and complaining because he has to pay a lot of money in taxes. Must be nice.
so yes, until kubota and deere and mahindra and Kukje tractor manufacturers start to act more like CAT does, then hire (and pay) their guys similarly, the type of service that you get is not going to get 'that' much better.
