I don't want to offend any orange owners, but my experience with a Grand
L3830 was not pleasant. I had some reliability issues including a complete HST failure fixed under warranty for $3,000+ at 50 hours...unknown reason. I treated it well, but then the rear 3PH began it's funky chicken at 75 hours, but disco was out, so another warranty repair was in order....a metal shaving was to blame. Thirdly, the loader control detente valve froze every winter rendering my loader bucket only partially usable...unacceptable. The dealer said Kubotas fix was to drill holes in the base of the detente valve to allow "condensation" to escape...I did that and then had hydro fluid slowly leaking from the holes. Nice. Then the 3PH arms were always hitting my BH90 subframe...bent them a few times...I'll take blame...but why is the subframe where it can interfere with the 3PH arms? Also, ran the unit in low range almost exclusively due to my property characteristics. Gets frustrating moving in slow motion all the time. Motor stalled all the time when loader was full unless I was in high rpm...too much drama for some simple tractor work.
Anyway, went to local JD dealer, bought a 2305 for smaller chores and immediately noticed how much more R&D went into the functions. The feel, motor, loader removal, MMM removal, etc. all so easy. Checked out the larger frames...3000 & 4000 series and decided to go for a 4720 w/BH448. JD loader, bucket, and BH all come off and on easier than Kubota...and JD uses a pins for tool-less removal/installation. The Kubota required a variety of wrenches, sockets, etc. There was a day when I could not get the pins back into the Kubota BH90 due to some uneven ground settling between uses. It took me almost 3 hours to get it back on...made me dread the whole operation. Also, paint fade and plastic dash faded into oblivion on the Kubota...that was a disappointment. In Kubotas defense, I will say the BH90 was one heck of a BH and the loader was strong.
Now I have a 4720...loader comes on/off easy, bucket comes on/off easy, and BH448 comes on/off easy with pins. Loadmatch keeps the motor from stalling and I operate in midrange most of the time and get things done much faster. I understand these are different machines and frame sizes...but whoa...JD just simply makes my work easier and faster. Some may say the 4720 is overkill for my needs and is good for rear PTO power...however, the HP on the 4720 lets me fly up hills, carry loads, and get work done faster so I have extra time to play with my kids.
On the JD downside, I would say the BH448 has a little more play in the operation and it's greater hydraulic flow demands greater attention and focus. The loader has more restrictive roll-back...bottom line...I spent a bundle to trade up to a 4720, but no regrets except I should have done this in the first place. Don't focus on numbers/stats...just operate them all and find who the best dealer is who can support you.
To all the Kubota owners, I say this with respect...people have strong opinions about their tractors just like trucks. Kubota makes great products...they would not be around and own most of the market in their classes if they did not...my experience is contrary...I absolutely love the feel, operation, simplicity of changing functions, etc. of the JD. Enough said. Whatever tractor you have, enjoy the ride.
