WD gear ratios

I was tuning my old WD couple weeks ago and got to wondering why the high speed gearing. I had a WC the same way. I have no use for 4th at all since its somewhere around 11 mph. 3rd isnt particularly useful either. I could however use a granny gear say to allow around 1 mph to manuever in close quarters without slipping the clutch. Did the company offer optional differential gears so this tractor could be used as a utility tractor? or perhaps some sort of optional two speed step down transmission? I have looked and thought how it could be done under the shade tree.. Everything from smaller rear tires to splicing in an old 4-speed truck transmission. The tires would screw up the hitch geometry and the transmission would slow the shaft that turns the hydraulic pump and the PTO, thus screwing those things up. Only real solution is to come up with differential gears that would halve the speed of the rear axle. I cant be the only person who wants to use my tractor in "low range". Anybody out there come up with another solution or a source for differential gears to slow it down? I rather hate to sell it and buy a more modern tractor and I dont particularly want to butcher it either.

The transmission on a WD is just fine... 4th is not used around the farm, etc... - it's a road gear - used for transporting the tractor (and something that you might be pulling down the road.

I used to plow garden with our WD when I was a teenager. I had a two-bottom mounted plow and pulled a trailer behind that with a pull-type disk - believe me 11 MPH seems slow when you're traveling 5-10 miles to get to a job site..

1st and/or second are used for plowing and other slow/power work.

3rd, is great for disking and such - where you don't have to run the tractor at full throttle (aka: you don't need power).

I'm wondering what you're trying to do with the tractor that 1st gear at a low throttle setting isn't slow enough. Heck, I've plowed, disked, moved snow, etc... with a WD - it's a great tractor.

Maybe respond to both replies with this one post. First I grew up on a farm in Iowa when lot of this old stuff was still being used as a main tractor (although my family owned Farmalls, not AC's, thus my lack of experience with AC's) so I understand wanting some speed when plowing and disking. I also understand road gear although that would be suicide on busy hiway now. And frankly although my engine is in reasonable shape, I think it would labor to run in fourth just pulling itself except maybe when going downhill. Even fresh brakes arent that good with hills around here (Ozarks). As to why I can't get by with minimal throttle in first. Have you folks ever heard of a PTO. Some implements require not only more power than is available at idle, but require high engine RPM to get a fairly constant full PTO speed. It must be real fun for anybody trying to use a hay baler with one of these if he's going uphill with a heavy windrow. Heck with the hills around here I've had to really gear down with a much bigger, much more modern tractor when baling (helping friend out). Anyway, I mainly use my WD to plow the garden and run a brush hog along with occasionally a boom, scraper, etc. Running a brush hog at correct RPM in close quarters avoiding obstacles is quite the adventure in slipping the clutch and holding the brakes and manhandling the manual steering all at once. Frankly although I love my old WD, its like driving a more modern tractor around in high range all the time. Surely all WD's weren't sold just for plow tractors to people who lived in flat areas. I did look at many past messages on this forum and I am not the only person who would like to slow Alice down. One man did say his WD45 was too fast for running a baler at times (no surprise there). Also somebody was trying to gear down a WC (about same speeds as WD- I know I also have a rough old WC) and found that the differential gears in some old, but rare AC cottonpicker would interchange to cut the speed. And I think somebody mentioned the possibility that a two speed aftermarket step down transmission was available for the WC at one time although probably very rare. All in all, I get the feeling that this speed issue is a sore point around here. Allis WD is a great compact, rugged and simple design, but I am also realistic and will admit its shortcomings. I guess I had the idea maybe someone along the line made a run of replacement differential gears or some other good method to make Alice more than a plow tractor for the back forty. I really didn't expect a "love it as is or sell it" attitude.

The WD speeds were set by what speeds that moldboard plows and disks worked best at. If you want creeper gearing you will need a newer tractor.

slower speeds are nice combining,picking corn ,etc. i think a good transmission shop cpould find you serviceable gaers to slow it down . high speed is used also for rotary hoeing crops! i've planted in 3rd gear before. but a lower gear would be nicer. i'm still thinking about it myself. so you're not the lone ranger !! =)
