3x20 Cab max side slope with spacers..

Greg don't take this the wrong way

Not much different than "with all due respect", it's virtually certain the next statement will be rude or hostile or simply discourteous.

Why do you get so "worked up"? Just because someone does not agree with your opinion, or accept it as fact, is no reason to be insulted.

I'm not worked up, I'm simply insulted. First off, PCABE5 hasn't even contributed to the actual topic under discussion. Secondly, my opinion is not what was addressed. Throughout this thread I've pretty much stuck to relating personal experience on 5 tractors on this very same piece of ground; 4 open station, one JD3720 cab w/spacers. I stated fact based upon experience, which can be fair game - provided the challenger can offer substantive counter experience. But just to pop up out of the weeds with a shot about "knowledge of the subject"......

While I'm at it, what was your contribution to this discussion Arlen?

People are nicer on "the other JD forum". How's that for a contribution? I know it's not much, but it's all I got. Oh, my tractor is bigger than yours
Seriously, lighten up. this isn't fair to the OP. I apologize for my own role in this.

A cabbed 3520 is one of the machines I am considering for my next tractor purchase. The thought of a cab and heat for snow removal at -20F is very enticing. However, I live in a flood-prone area and have a raised driveway and a ring dike around my property that I mow and maintain with my tractor. I am concerned that the more top-heavy cabbed machines will not be stable enough to handle the slopes. The steepest side slope I have to operate on is about 27 degrees, and the majority run in the 20-25 degree range. The worst slope on the property is a touch over 30, but I hope to add some fill to that area this fall to level things out a bit.

My current tractor sits at 66" wide in the rear and handles the slopes like a champ, even the 30 degree one. If I was to go with a 3520 cab I would go with the 15-19.5 R4's and Unverferth 6" spacers to punch the tires out to around the 70-72" wide range for stability. My gut says that the tractor will still be too unstable even with the spacers. Is anyone running R4's with 4-6" spacers on slopes similar to this, and how does the machine handle it? Thanks.

First would be the JD 3x20 would be a great tractor choice. Very capable.

Second, the smaller R4's have been recommended by some users for their lower CoG along with liquid fill.

Third, the taller R4's add more weight when filled but they will raise your CoG. Could be a toss up.

Fourth, you are describing some serious hills sidehills. Stability might be a concern no matter how it is configured. Your operating would give you the best idea of stability.

Fifth, the rear wheel extensions have been found by many users to enhance stability. My only comment would be that if something "were" to happen you may not have warranty coverage for the rear axle. The key is if something happened. Many operators have lots of hours on this setup without problems but I thought it was worth mentioning since the axle would be pricey.

Thanks to all those who contributed on-topic responses to my thread. I ended up purchasing a used 400hr 3720 cab tractor with loader, front blower, and backhoe late last week. It is sitting on the larger R4's and I hope to get it home in the coming weeks. I will make sure to post when I get it in, and with what I decide to do with spacers and ballast.

Congratulations. 400 hrs is just broken in.

My 4720 is 92" wide with wheels dished out. Just for info.. This is too wide for my use. Dish in too narrow. Dealer is supposed to get the 8 position wheels and exchange them.

Congratulations on the purchase! I think you will be very happy. Post some pictures when you get it home.

FYI, the (spacer) stress issue is with the aluminum axle housing and bearing carrier - not with the steel axle itself.

Good to hear. The shorter R4s would have been a better choice IF you do a lot of backhoe work. That said, I found the drawbar to be quite low to the ground, so you'll probably appreciate the extra ground clearance provided by the taller R4s. In fact, I bought a tow ball with a 2" riser to increase tongue height when I pull a trailer. Anyway - if you think my experience with 3720 tire ballast and rear spacers may be of assistance - feel free to contact me via the site PM feature.
