........ but this 3720 at times has gotten downright scary. Never once put any of the previous four up on 3 wheels either.

It's even more scary when you are over on two wheels. Happened to me two winters ago when blowing snow going down my driveway with the 59 blower on the front. Started sliding sideways due to ice under the snow and then hit a spot with no ice. Tractor went over on two wheels and luckily came back down on all fours instead of going over. This happened with weighted tires and spacers installed. I'm sure the tractor would have gone over w/o one or the other installed. But, like I said above, I wouldn't part with this tractor.

Greg,

I'm not saying you can't tip the tractor or get it up on 3 wheels as we both have found out. What I am saying is that a lot of people get very uncomfortable long before the tractor is in danger. A very good thing actually. If you are operating on side hills a lot it makes sense to widen the track of this tractor AND put fluid in them.

Out of curiosity, what other tractors did you have, and do you know what the rear track is? I widened mine to 67 overall on purpose. I may bring it down to 64 for the long term though. My McCormick was about 65 inches wide and I had it on hills that definitely made me nervous but the tractor was stable. That said, I had loaded tires on that tractor which do make a big difference on hills.

Two 25hp Jinmas, one 35hp TaiShan w/FEL, and one KAMA 454. I know for sure the KAMA was 66 inches wide - front and rear - and had the widest track of the four. The 35hp was at or under 60" because the FEL covered all tracks. The pair of 25hp, well - I'd guess at or under 57". All four had nominal rear wheel weights, the 3 without FEL had suitcase weights up front. All four were stable enough where I never felt a need to add liquid ballast. I did however, consider loading the fronts on the 45hp for an entirely different reason. It had a tendency to be light in the nose when mowing uphill with the rotary cutter.

But all were comfortably stable on my 30 acres or hillside. This 3720 cab however has a 300X loader with 4-in-1 bucket, about half a ton of RimGuard on all four corners, and a 700 pound ballast box. It's on fat R4 tires with the rims turned wide side out. And I still feel uncomfortable on the very same 30 acres of hillside. Only 60+ hours on it, but I'm giving serious consideration to trading for something more stable.

You would be money ahead buying 4" of spacers from skidsteer and put them on rather than the 1" gain from inverting the wheels. It makes all the difference in the world. :thumbsup:

Agree. Adding SS wheel spacers on my 3720 cab tractor with smaller R4's made a world of difference in stability (and perception). Well worth the $300 spent.

I give up, how could I possibly be "money ahead" after spending $300 on spacers? I know, figure of speech. But it wouldn't stop at just $300. I'd also then have to replace a new 4-in-1 bucket and a couple thousand dollars worth of TPH implements that all suddenly became too narrow.

Frankly, I think Deere did not do its homework with the cab 3x20 series; there is a clear balance problem. Greg is certainly right about the pucker factor. I go to my mom's hundred acres and help her mow with her cab 3320, and I find myself bracing for dear life on mild slopes that would mean nothing to my OS 3038e. In her tractor I end up crawling along over hilly segments the 3038 would move through at a normal pace. It really is quite frustrating. Though, thankfully, most users are not reporting a tip-over, just look at how many darned posts there have been on this subject on tractorbynet.

If I ever decide to trade in the 3038e, I'll skip the 3x20s and go to a 4120 with wide-set R1s.

Can anyone comment on how/if adding wheel spacers affects the warranty?

I've asked my dealer but have yet to get a straight answer.

Should have no effect on the warranty coverage - at all! Completely "non-invasive" treatment... :D

No change to engine, transmission, cab, drivetrain - nada.

If your dealer argues otherwise --- go get another dealer --- fast!

It shouldn't affecct the warranty, on mine the spacers I used basically put my width to the widest I could have had if I would have had R1 tires (I have R4's). However to be sure I paid a little extra for the spacers and bought them through the dealer tht I bought the tractor from and had them install them.
