![]() ![]() Newer versions only offer one ratio and its much faster. Posted 20:16 (#5724721 - in reply to #5724691) Subject: RE: Road Ranger 15 sp shiftingĪre you talking about a newer roadranger 13 or an older version of the 13? A 6613 has similar low ratios to the 15spd. Your 1st gear in your 13 is lower than your deep reduction 1st gear in your 15? If a guy did not need OD, I think the non-OD 15 has a lower 1st than the 13 OD. Posted 20:06 (#5724691 - in reply to #5724203) Subject: RE: Road Ranger 15 sp shiftingĪre newer 15s any lower geared than older ones? Comparing specs, if a person wanted an overdrive transmission, the 13 over still had a lower 1st than the 15 over according to our Roadranger spec brochure, and the only 15 on the place came home recently in a 1991 Marmon, its the OD one with the turned around 4th and 5th, and I personally like a good 13 compared to it, seemed to have a lower 1st than the 15th. Borrowed neighbors tandem with 15 over this spring, it was like meeting an old friend I hadn't seen in years. If I could get a big torque rto 15, it would be behind that Cat in a heartbeat. Every once in a while I find myself still trying to stuff it in top gear at the dash. Full shifts, split on top hole to the big sprocket. ![]() Moved to newer truck with an 18 speed- 15 yrs ago. My 13 most times gets going OK, only occasionally have to reverse a foot or two to get a bit of 'easy' going. from deep 5th to low 4th.įorgot to include that in the mix also was a load for a neighbour to help him out - and his was an 18! Simple thing to remember with a 15 is to downshift one gear whenever coming out of deep reduction if you are going for the next progressive gear. 18s have nearly the same low gear ratio as a 15ODs low-low (both high 14s,13spd is in the 12s ). I love the 15,an 18 can replace it but a 13 cannot due to its fast low gear ratio. Yes the ratios are different and the OD is a touch slower than a 13/18 (0.79 vs 0.74 IIRC ). And possibly the overdrive ratio is different in a 15? IIRC, the gear ratio's are closer together in the non-reduction gears of a 15 than they are in a 13 when not splitting. But, IIRC, there are 2 gears in the deep reduction that are slower than first gear. I make it a point to either park only on dry, firm topsoil, or good solid field lanes.īeen awhile since I've run a 15 speed. A 15 speed is basically a 10 speed with a deep reduction, which is excellent for getting out of soft fields, but not as nice on the open road.ĭepends what you're doing. I like being able to split those top gears. Personally, I'll take a 13 or 18 speed as long as I'm not pulling heavy out of soft fields. You get to shift straight through 12 nicely spaced gears. You can go 1-2-3-4-5- (air shift )-4-5 or 1-2- (air shift )-1-2-3-4-5 or any combination between.ġ5 speed is my #1 choice for transmission. Yes, when shifting a 15 out of deep reduction move the lever one hole back from wherever you are. Shift 1-2-3-4-5 - now what is the next gear in the bottom ten of the rest? Ĥ00 hp Cummins quite happy to shift a full load on hard surface in 1st gear of normal range. Different! ĭeep reduction to get moving loaded in 'dead' paddocks. Went and helped son in law for a day - driving his Ford LTL9000 - 15 speed. Retired, but carting grain with my old "S" line inter - 13 speed R/R.
