4wd engagement

[mpegg]

Does anybody have a hard time getting their 2300/2310 out of 4wd. Mine goes in very easy, but to get it out sometimes I have to rock the tractor back and forth.

Between it being mechanical 4wd & the front tire lead ratio, that's normal. Try just backing up a little, or raising the front with the loader, it should come right out.

Both the 4WD, and the diff. lock can at times, require finesse, such as holding your tongue in just the right position, (usually slightly out of the mouth and, to the left or right), to be able to engage and or disengage them. This is normal.

Yep normal. Often I have to go forward or backward a a little or turn the wheel at the same time to get it to disengage. I'd rather have it engage easily and disengage the way it does than the other way around. As well, the rear diff lock sometimes takes a little moving around before it releases. Just have to release all the tension and binding in the drivetrain.

Try accelerating and then disengage just as you let off the throttle. Works real well on my Mahindra.

Thanks guys, It sure does make a person feel better knowing something is normal, especially when its your best toy, I mean tool in the shed.

Make sure that you are on gravel, dirt or lawn when shifting out of 4wd. Tractor has a front axle lead ratio. If you are on concrete or asphalt and the tractor is in 4wd the tires can't "slip" causing the the drive train to be lightly under load making it harder to shift out of 4wd.

Curious, it's not clear to me what you mean with "front axle lead ratio". What does that mean?

Glad someone asked the question about the engagement, mine is only a couple weeks old and does all the above. It also, on occasion, doesn't want to go from Neutral to LO gear....I just shift to High first (or a few times) and then nudge it into LO. I'm guessing this is the same deal.

 

[DEWFPO]

I was told the axle ratio on the front axle is 1% faster on the 2300's than the rear axle ratio so that the front will turn better (in 4WD) than if they were both the same.

I think I've had mine in HI only once since I've owned it, most all the work I do is in LO.

DEWFPO nailed it, except for the ratio (3.12%)-- see photo of svc manual spec sheet

Thank Walt, I much prefer data over arm waving.

Front lead ratio means how much farther the front tires travel than the rear tires. In 4 wd drive, you want the front tires to travel just a little faster (farther) than the rear tires so they "pull" the tractor. If the front tires travelled slower, the rear axles would have to "push" the front axle around. A slightly positive front lead ratio also helps when turning as someone stated before. The down side of having incorrect front axle lead is excessive turf damage, excessive tire wear and overloading the front axle differential. On turf tires, you want a front axle lead ratio of 1 - 3%. On ag tires and R4 tires you want a front axle lead ratio of 1 - 5%. If the tractor is going to be used often on a lot of hard surfaces (i.e. concrete), use a 1% lead ratio irregardless of tire type. Tire pressure and tire size both affect front axle lead.
