Large JD CUT questions -

[JohnMiller3]

<font color=blue>...would you recommend the 13.8-28 or 16.9-24 rears? ...</font color=blue>

If you're gonna do a lot of slope work, sidehilling, etc... you'll want as low a profile as possible... go with the 24 rears for lower COG and wider footprint...

Sometimes that 1 1/2 - 2 inches makes a world of difference in the seat for newbies for the comfort factor... /w3tcompact/icons/blush.gif

The 16.9-24's are actually a tad taller overall (53 vs. 51.9), and a tenth taller in loaded radius (24 vs 23.9) - but in any case I doubt there's a height difference you'd notice.

However, they are going to put a lot wider (over 3.5" wider) paw on the ground - with an inherently wider track at any wheel setting. Also a lot heavier filled - 200 lbs. more per tire (650 lbs. vs 450 lbs. each), so they probably do make the tractor feel a bit more stable.

I just wondered if there are use conditions (other than trying to sneak through a narrow opening) where the bigger tires would be a bad idea.

(whoops) ... not a wider track but a wider overall width.

Tim....

When I bought my 4710, I opted to go with the 16.9-24s. Not sure of what your intended uses might be but for me I was looking for that wide footprint, as John put it, to enable easier negotiation of wet and swampy areas that I knew I'd be working in. I believe it was about an extra $100 and I feel it was worth it. Even though I didn't have any other ag tires to compare it against, these 16.9-24s DO PROVIDE plenty of traction under wet ground conditions that I would not normally feel comfortable working in (and still sometimes don't). I also was able to VERY EASILY negotiate the two recent 18"-24" snowstorms we had when plowing. The tires 'dug' into the snowpack and provided just enough traction I needed to complete the job....without chains I might add.

A normal 12' disc you would probably be ok. I've got a JD 210 which is a very solid and heavy disc. I can pull it but it's alot for the tractor if it's all the way in the ground.

For ballast I just use implements for the most part. I've got 600 lbs. on my rear wheels but other than that I'll use the loader, box blade, or a round bale on the back depending on what I'm doing.

I have mixed feelings on the tires. There are situations where they will both come in handy. If you like the wider ones don't worry about the width and tight places. You can set the wheels to a significant number of width settings.
