case dozer fast in first gear

bdmartin · Jan 4, 2011

I have a 310c with a three point hitch. I intend to use it on the farm. It is very fast to use on the farm in first gear. Is that normal, were they all that way? Did some of them have dual range tranmissions?

Case 310 crawlers suffer from the same problem at Oliver Cletrac HGs and OC3s. That because they use the same Clark transaxle with a fast 1st gear.

The Case crawlers that use torque-oonverters don't have that problem.

It's also why having a aux. transmission makes a world of difference.

Case 310 - 1st gear at full throttle is 1.8 MPH
Cletrac HG/OC3 - 1st gear, full throttle - 2 MPH
HG/OC3 with aux. in 1st low - .6 MPH

The Case 310 is a little better since the final-drives are geared a little different.

Compare to a Deere of Oliver OC4
Deere 420-440 .85 MPH in 1st
Oliver OC4 (with low range) .8 MPH in 1st

I have a Case 320 bulldozer, basically the same as the 310. I have never checked the speed in 1 st. gear, but does not seem exceptionally fast. It has more power than the tracks will hold and I have 12 inch tracks on mine. I also have M-3 forklift finals and sprockets on mine. Is it possible the ag tractor has a different gear ratio?

I never found a 310 to be fast. 2nd was work gear! Pulled a 2B 14" JD trailer plow and Case 6' Bog harrow, reclaiming ground in the 60's The only time we used First gear was when we were diging out rocks or pushing out thorn apple trees, mainly to save the clutch. I still have one just like that one, wearing 14" pads and adorned with full logging gear, sweeps, ROPS, and winch, adding about 1 ton. 2nd still work gear. PS it is a 1957.
