GEAR RATIO?

[bx1860]

I am trying to find the front and rear gear ratio's for the bx1850 and 2350. I have searched here and every where. Call the local dealer and they do not know either. Can some one please tell the the ratio's or let me know where I could find them. Thanks.

I would call the corporate office as they buy everything/build everthing here in the states except for the motors/prime movers and transmissions

Been down that road too. No luck.

Compare the rolling circumference ratio of the front tire to the rear.
If you have the tractor close at hand and a helper, Jack up the left OR right side, both front and rear. Then count how many full and partial revolutions the front tire makes as you turn the rear tire, at least, 10 full turns. Front number divided by the rear number is the ratio. KennyV.

If you want the larger wheels why not get the 2350 instead of the 1850 ?

Rear tire diameter divided by the front tire diameter=front to rear ratio.

Hey BX1860, check your last thread you started. I just explained it all there.

 

[bx1860]

Jr, thank you I will do that.

LB, I have a set number I cant go over in price and the 2350 is more then Im willing to pay. 232 a month compared to 300.

LB, I have a set amount I can't go over in price and the 2350 is more than Im willing to pay. 232 a month 1860; compared to 300 2350.

In that case I'd just go with the 1860 and not be concerned with wheel size .
I have a BX23 with the large wheels and a BX1500 with the small wheels.
As for performance I can see little or no difference between the 2 differen size tires.
You are getting into a hassle and an expenese yeilding very little if any gain trying to switch rims and tires.
I just can't see where it would be worth it.

It will be worth it to me. 68 dollars a month more for 48 months or 300 dollars one time to get what I want with out buying a diff tractor. I dont see why you would need 3 tractors for less then 3 acres, but then again I guess we all have our own opinions

1*It will be worth it to me. 68 dollars a month more for 48 months or 300 dollars one time to get what I want with out buying a diff tractor.
2*I dont see why you would need 3 tractors for less then

1* what I was referring to was the 300 extra not the 68 per month.
2*That's beside the point as all I was trying to do was to give you a perspective between the 2 sizes of wheels from a party that has hands on experience running both sizes of tires.
Made my day finding out my effort in trying to help you and understand your position wasn't appreciated.

Rear tire diameter divided by the front tire diameter=front to rear ratio.

Not true. Close, but off a bit.

The gear ratio of the front is higher (smaller number) that the rear as the front MUST spin the tires faster or drivetrain bind will occur. You want the tractor to be pulling with the front tires a weeee bit faster than the rear. About 5% is the target with an acceptable range of 3-7%. Some are out as far as 10%.

The generally accepted way is to put white shoe polish marks on the front and rear tires. Then in 2wd, go forward 10 rear tire revolutions dead straight. Repeat going the opposite direction. Write the number of front tire revolutions that were needed to equal the 10 rear tire revolutions.

Repeat that, but with the tractor in 4wd. You will get a number larger in 4wd than in 2wd. So, if it took 20 when in 2wd it would probably take 21 when in 4wd. That ratio of 21/20 is 105% or 5% over.

You can then use your math skills to determine the correct front tire size if you increase the rear so that you will maintain that 5% target over.

I understand that won't get you exact gear ratio's. You're completely correct and I agree with you. However if the only reason you want to know the gear ratio differences because you want to get a different tire size and keep them the same ratio this is the easiest and fastest way to make sure the tire size ratio is correct.
