I currently own a D17 series 4 with an allied 600 loader which I use for working 2500 trees on my 20 acres. I made a 3pt bolted to the drawbar and a quick coupler matched to all my implements. It doesn't have the traction boost, someone previously removed it, and I can sure see the benefit to it when I break new sod with my 8" deep tillage spikes. Way too much manipulation required, but we git'r done anyways. I also have an h3 crawler I've been restoring for a while which was in pretty rough shape from a life of busywork. Lately I've been contemplating getting another smaller tractor in the 40-50 hp range so I'm not stuck at crucial tree planting times if my D-17 is down for repairs. I have been looking at D-14's which I'm concerned weren't made in enough numbers for readily available parts, the D-15 which I know quite well already because of the H3, but then there's a tractor called the WD 45 which pushes almost the same horses as my D17, was made in hugely abundant numbers, came with the traction boost which I feel would be invaluable with my deep tillage cultivator, looks simple to work on. I'd like to hook it to my 8' two bladed mower, the cultivator, and a wood chipper. Will the d-15 handle the job or should jump all over a WD45?

A WD45 is cheap horse power, they were made in large numbers and don't command anywhere near the price of a D series. They are also very simple and easy to maintain. the only weak spot is they are a little harder to get on and off.

the 45 compares direct to your 17, the 15 will be down on HP as would a 14 although they are both great tractors.

D-17 was 53 PTO HP.....WD45 was 43 PTO HP.....D14 was 34 PTO HP.......early D15 was 40 PTO HP and series 2 D15 was 46 PTO HP. The late D15 never really replaced a good WD45..... and a WD45 was never equal to a D17 unless it had M&W pistons in it and 12 volts and then it still didn't weigh what a D17 did. Many WD45's didn't have power steering if that's a concern. I'd look for another D17 only older than a series 4 for what you're trying to do.

I have several WD45s and a Series I D17 gas. I love the 45s and they are my favorite tractor but they can't compete with a healthy D17. To me the D14 and D15 tractors, just don't have the same guts as a 45 even though the the later D15 had about the same horsepower. I would take a D17 as first choice, then a 45 and then the smaller D series.

Personally, I love the D series. Easy to get on and off of, and have a nice ride. A good number have power steering. The greatest benefit is the power director - the greatest invention AC ever came up with in my opinion. A total of 8 speeds, shift on the go, nudging it to go slower. Go find another D17 with a traction booster that works and you will be good to go!

sounds to me like you need another D 17. That's the way I'd go.

Thanks for all the advice. I'll keep my eye open for another D17 or a WD45. If one comes along in good shape. I see there are a few in Ontario, but I'm from Saskatchewan which is too far unless I freighted it here. That's the problem with living in such a sparcely populated part of the country. These old AC's don't come around for sale all that often. I had to go to Manitoba, about a 3 hour drive for the D17. Before I settled on that I burned a lot of fuel and wasted a lot of time turning around disappointed in peoples yards, trailer in tow.

If tou are going to use your tractor in the field and not just to look at , the D-17 is a lot better on your back and rides much better.

I have both a Wd45 and 2 D-17s.The WD45 is a great simple tractor that is easy to work on and parts are easily Accessible.Few things to remember,with no hi-lo; no road gear(only 9 miles an hour),1st isn't slow enough(the power director solves this but no need with the 17 and 8 speeds),electric and hydraulics much better on 17,D-17 is a much safer and comfortable tractor to use.I am sure the WD45 would make a good backup tractor,but would not want to have to use it everyday.8 foot bush hog would be too much for the PTO set up.My 6 foot gives my WD45 all it can handle.Just my thoughts

Well, that is interesting that the wd 45 has trouble with the 6'. I wonder though if the 8' with the two 4' blades is perhaps a little easier to spin than the 6' blade as the rotating mass might b slightly higher, but at less radius. There is also a D19 in nice condition for sale, but I have read that the straight axel tractor is not as bullet proof as as the others. Just trying to get the most feedback to help make an informed decision, thanks for all the feedback so far. I did a lot of research before I bought my d17 series four and sure have been happy with the performance I get out of it. I especially like the external hydraulic pump, sure runs implements like a champ, in fact I've bought another set of hydraulic valves for it so I can leave the FEL on it while hitched to my little scraper to help keep the front end down. This little tractor is a real workhorse! I honestly can't see how the manufacturer of such a great tractor disappeared. Chris
