L2900 MFWD Ratio

PitbullMidwest · Feb 7, 2008

I'm the proud new owner of a 1998 L2900GST. The unit has a LA480 FEL w/standard duty 60" bucket and R4s. Overall, the tractor is in very good shape with just over 1000 hr. and belonged to the owner of a Kubota dealership. He told me that the fluid changes were performed about twice as often as recommended and that he ran Rotella in everything except the transmission, for that he used Kubota oil.

The only down side if there is one, is that the R4s will need to be replaced within the next year. My questions are:

1. Are there any L2900 owners on TBN that know what the MFWD ratio is for this model or where I could find it?
2. What brand /size are you currently running?
3. Does anyone know of an online source for R4s w/pricing?

I haven't taken delivery yet so I can't provide any other details about the current tires except that it has Firestone 420/70-24 rears and Titan 10-16.5 NHS on the front.

This is me ------->

except I'm orange instead of green.

I don't know any exact numbers, but I found this a while back and figured you'd find it interesting too. http://tinyurl.com/2mfqn5

Thanks Mike,That's good information to have.

I know the rolling circumference of a couple different brands but don't know the front/rear drive train ratio. According to Firestone anything between 0-5% lead is acceptable. If I had the tractor I could figure out the lead/lag using this method: http://www.firestoneag.com/tiredata/info/info_lead.asp.

Again thanks for the link.

The interaxle ratio on the L2900 is 1.57 - meaning the front tire goes around 1.57 times for every round the rear one make.

Good luck

When I needed the ratio for mine I got it at the farm tire dealer. He had a book that listed them. I would double-check by doing the math on the current tires you have with the ratio they give you.
As stated, your "lead" by the front tires should be 2% to 5% but it will math out to 102% to 105%.
Good luck, this is the right way to go about it.
