JD 6420 $13,000 higher than M105X

What you guys are talking about is the mfwd system being integrated into the brakes. When you hit the brakes it electronically engages the mfwd. You DO NOT have 4 wheel brakes, you have the 4wd system engaged. It's also standard equipment on the 6415 and 6420 as are all of the other supposed kubota exclusives. Reading through these posts it's exactly like reading the brochures for the 6415 and 6420 series. Kubota did a good job copying that tractor all the way down to the automatic shifting for field work. They even used Deere's exact diagram to show it.

does Deere have anything like Bi-Speed turn?

 

[cowboydoc]

Actually, my opinion, deere's system is better. Deere has the triple link suspension that puts the turning angle right at kubota's. The folowing is also standard equipment on and 6000 series tractors. If the bi-speed turn is anything like the joke they had on the B series then people are not going to be too happy with this system on the big tractors.

<font color="green">MFWD with 52-degree turn angle



Caster/Action™ MFWD axle is available on all models, regardless of the transmission.


Provides the following advantages over 2WD tractors:

Converts more engine torque to drawbar pull power for increased productivity
Reduces wheel slippage with less tractor ballasting for reduced soil compaction and increased fuel economy

MFWD operational features




On-the-go engagement is accomplished with a console-mounted switch that enables the operator to engage or disengage mechanical front wheel drive without clutching.

Exclusive 12-degree Caster/Action design:

Permits wheels to tilt and tuck under tractor chassis to achieve sharp turns
Improves stability and steering accuracy and provides positive traction on turns
Allows a maximum 52-degree turn angle

Centerline design provides excellent maneuverability and crop clearance.

High pivot point axle design allows axle to oscillate a full 11 degrees for better turn angle and less stress transmitted to tractor chassis.

Multi-position front wheels provide a wide range of tread settings from 59.1-in. to 74-in. If a wider tread setting (74-in. to 80-in.) is desired, it can be ordered through Parts.


Limited slip differential is base equipment:

Automatically compensates for traction differences to maximize pull



Large, full-coverage flexible fenders are available:

Help protect the operator station from mud and debris
Feature a full range of adjustments to accommodate a variety of tread settings and tire sizes



Optional Equipment On : 6015 and 6020 Series Tractors

The other comment about the kubota having more gears depends on the transmission. The automatic transmission in the deere is a 24 speed. The kubota is a 16 speed. Deere also has the automatic transmission which was copied by kubota. Deere also has the IVT available which is as close ot a hydro as you will get on an ag type tractor. Kubota doesn't offer this.

With regard to the ground clearance issue I wouldn't brag about that. Higher ground clearance means more chance of a roll over. Because of this Deere offers two options in the tractor. If you need a higher crop tractor they specifically make the high crop tractor or for more stability they have the standard model.

Deere also has electronic front locking differential.

Nice thing about the deere is you can get it stripped down or load it up with everything you need. You have choices. The kubota is pretty much the way it is. It's a good copy of the 6000 series but aside from the bi-steer there is nothing new or special about it.

And I'm not saying that the kubota won't be a good machine. But it is not anymore tractor than the deere. The only thing that would really bother me is the reliability of that bi-steer. Other than that you know kubota is going to put out a great product.

my understanding is that bispeed is not specificly designed to improve the turn angle. Its intent is to reduce pawing and turf damange done when you turn tight corners in 4WD. Turning radius does improve as a biproduct.

The 24speed tranny is an option on the 6000 series right? I thought 16x16 is standard.

Neil,

You have way more inside information that me on the bi-steer. On the website and talking to the dealer here they touted it as decreasing the turning radius. If a person is worried about scuffing with these bigger tractors I think they're in the wrong ballgame. /forums/images/graemlins/wink.gif These bigger tractors are going to leave marks regardless. But maybe Kubota is trying to lessen that I'm not sure of that.

You are 100% correct that the 16 speed is the standard transmission. But still the standard 16 speed is quad range just like the kubota so I'm not sure where the posters comment about having more gears to choose from came from. They are both quad ranges. The 24 speed quad is an option as is the IVT.

Cowboydoc,

I don't know how much Neil keeps up on ag machines but I believe the M100 and M120 models also had bi-speed. It isn't for turf damage in this rig I can't imagine. I would be certain it is to get sharpen turning. It would obviously help in tight muddy turning to avoid the plowing of the front end.

Can't say it would be a feature I'd want until I learned more about it.

Thats what I was talking about, "Turf Damange" was probably not the right word. That tractor accomplishes its tight turning though the way they arrange the knuckles between the axle and tire. As you eluded, I spend most of my time under 60-70 Hp. I would never claim to be the expert when it comes to this class machine.

Neil:

I have to side with Richard all the way on the bi-speed turn. One of my many Kubotas was a bi-speed turn model...lets see, I've had seven Kubbies in 19 years.

I never liked it, as a matter of fact, I left it disengaged 95% of the time. I'd not want to put big power in a Kubota bi-speed unit unless I was absolutely sure of the engineering and I'm not.

My M9 and our (my partners) 105 have plenty of wheel cut for our needs.

Interestingly, I wanted to put front fenders on the M9 to keep the mud and dirt off the front lower windows and can't get them. That holds true for the 105 too.

I was told that every flexible fender set sold for any make of tractor, Deere & Company get a royalty. I want a set, actually 2 sets.

I'm not sure how the bi-speed works but I'd assume it is a planetary geared so if the planets are held versus let go it makes the gear change like an automatic tranny. I'd suspect the gears are as tough as nails and the band brake would be wet so it should last a while but it is still a wear item...

Fenders are a nice item, popular up here for cab tractors to keep the glass clear. All the old New Hollands have em, can imagine you could patent a fender? They were rigid though I think.
