3720 Stability

[xkbal]

I added spacers to mine and it made a huge difference to the stability of the tractor. I was somewhat worried about the extra stress but decided that I felt adding spacers to my tractor with R4 tires would not add anymore stress to the housing than having the R1 tires to the full width (my R4's are max width 58.9" while R1's are max 68.4").

I wouldn't believe any hype that spacers would be harmful nor that the 3720 isn't designed for the load potential. But don't see any need to go to more than 2" spacers either.
Perception running the 8N (where one sits quite low between the rear wheels) on hillsides and running the 3720 with cab (sit much higher) is a thing to get used to, and for some not an easy switch. Look at the hillsides these compact utility tractors operate on along roadsides and I wouldn't even traverse them. But dips and rises will change our sensations quickly.

Thanks for all the reply's. I really appreciate the information. The 4x20 seems large but I would like to test drive a cab unit if I could find one. The local dealers in my area don't have any in stock. I also checked Bader's and D&G.

Do you think that the 3x20s could mow with the same ground speed as a lawn tractor? I know that they are capable of higher speeds but can you actually mow as fast without being bounced around too bad?

My 3720 cab tractor with 72" 7-Iron mmm will mow my 6 acres of lawn faster than the tractor it replaced, a JD X485 with 62C mmm. The 3720 mower is larger and it travels as fast or faster than the X485 mower but my lawn is quite smooth. Might be a different story for a rough lawn and/or if you have a lot of obstacles to mow around.

Sounds to me you have a really bad bouncy property. Is it really that bad. Reason I ask is, not sure if we are talking about a rut here and there or a straight out speed bump ****. What gear do you plan on mowing in and how fast are you mowing this lawn? Im saying this because I don't think a 4x20 is gonna help either if your property is that bad.

Yes a 3x20 rides smoother than a lawn tractor. BTDT. Have one of each.

I have a 2011 JD3720 cab w/standard seat and ballasted tires, plus a2010 JDx500 lawn tractor with HDAP tires. To me the x500 mows faster, is more stable, and rides more comfortably than the 3720.

Where does one get the spacers? Anyone have pictures? I'd consider getting them for my 770 if compatible. I mow some pretty steep slopes.

Do a TBN search on "Bobcat wheel spacers" for more info.

eBay. Matter of fact, there's a set there advertised as being for the 790. Stands to reason they'd fit the 770 too
