Tipping angle 3320 cab W 300cx

I don't know. Like I said, I had one and what would happen is I would look at the meter as I started a slope and checkit while I was moving forward. So you have this give and take action with the meter involved. It's not bad. Also it teaches you as you compare hills and your gut reaction.

And that is exactly what you want to do...

As a reiteration from an earlier post, even mild slopes can feel intimidating when first operating. Even me, with a fair amount of experience, still have that feeling. The tires on my (new to me) 4400 are considerably taller then my old 790's R-4's, so I'm feeling out the stability of this new tractor.
When a guy is brand new to these machines, even 5° can feel mighty scary.

Yep! Look at it this way, how many times have you looked at the speedometer on your car when you were going down the road and how many times have you been wrong about the speed you were going?

I had one of the Tilt-Meters on my 3720 and liked it. My 4720 now feels much more stable than the 3720. (I still have a tilt meter on my 2305). I've had my 2305 on 1 wheel once if you can believe it (not a fun thing). When I first got my 3720 I could tip it on two wheels easy with the grapple (fortunately due to the load and not the ground).

I always felt tippy with the 3720 on slopes, etc. - I put 6" (each side) unverferth extenders on it and that helped immensely. I had it 2.5 years and after using it a while I did get used to it. Although I've lifted wheels on level ground and going over obstacles many times, I've never lifted a wheel off the ground sideways on a steady slope though - I'm always extra careful. I also try to make sure I'm in 4wd on slopes so if I have to pull the front downhill quickly if the upper rear starts to lift I can. (This probably is more of a mental reassurance to me than would actually help in reality). Also, when I'm on a slope I usually have my 900lb 84" RFM low on the ground which may help just a little bit.

Thanks everyone. Some good things to look at. I'll check out the rim and see if they are in the widest position and will look into watering the tires. I have a length of concrete sewer pipe that just fits into the loader bucket. I can fill it with concrete for a front weight. Does 300 lbs sound about right or should I try for more?

Is there anything that you can add to the water to increase the density? Lead shot comes to mind. get rid of the bounces like a dead blow mallet? I'm joking but it sounds like it should work.

Water (for filling tires) isn't the best option. It's relatively light and it will freeze (not good).
Biggest bang for the buck is using Calcium Chloride, but that's corrosive. Calcium Chloride has been used for many many years though.
Windshield washer fluid, RV anitfreeze and beet juice (sold as Rimguard) are better options. Search on TBN for "filling tires" for more options/experiences and opinions.

Nuru,
This is the email I got from Deere:

"In regards to stability, the smaller tire is going to keep the machine at a lower center of gravity, so that may the correct choice. Also, these are 2-position wheels and it would be helpful to have them installed in the wide position for increased stability."

Thank you,

Rob-D, yes, and again they also state that the larger R3 turf specials do not fit with an MMM, and I have both installed and I have no issues. The specs indicate that I should experience significant interference between the tires and the MMM - noot and issue at all. I also can take steeper slopes with my wider softer tires as they are set to the wider settings. When I had the small R4s on my unit, the height was 88", now with the Taller, but much wider R3s, the unit stands at 91" and it is much more stable due to the wider footprint of the wider tires. With the MMM installed, and the wider softer tires, I am more stable than I was with the harder slimmer R4s. I think what is going on is that when I am in the unit, it sits a bit lower than the height I measured when it was empty. So being that I am probably closer to 89" with a wider stance - I get more stability on slopes and other uneven turf.

I never saw that the large R3's won't work with the MMM but I'll take your word for it because I've often said there are two groups at Deere, the designers and the writers, I'm sticking with the designers. Why would they sell a tire made for grass that a MMM won't work with? What's wrong with this picture?

I owned a JD 3320 with 60" MMM and 300X loader. I had it for about 1 1/2 years. My properties (owned and leased) are all hilly. I never got used to the tip over feeling of the tractor. I was so nervous on the 3320 that I eventally sold it and purchased a JD 2320. I owned a JD 2320 before the 3320 and was a whole lot more comfortable operating it on the hills. The 3320 was my dream tractor...... I just could not enjoy it for being so nervous.....too much money for something your scared of!

Hi Lt220,
I had the 2320 and went to the 3320 also. First, the 3320 sits higher and I think this may give the feeling of tipping more when in fact you're relatively safe.
There were a couple of things I did. I put on a tiltmeter, put the rear tires in the widest position and will put on weights in the spring. I personally don't find the 3320 to be all that tipsy. It's not the 2320, agreed, but the 2320 can't do what the 3320 can either.

Rob, my 3520 is fairly tippy, so I think it just depends on your terrain and how you use it. My property isn't too bad but is sloped a bit, but it is the small holes that kill you with this tractor. For example, got a decent sized cow elk about a month ago. Was able to gut it on site and load it whole and bring it back to the house. Used my tractor to lift it up to skin it. While that in itself was not a problem, I was backing up and my rear right tire hit a really small hole while on a very slight decline and my front left tire came off the ground. I am pretty quick on the draw so I was able to steady it but it was enough to about give me a heart attack and remind me how tippy this thing can be.
