Kicking around the idea of replacing one of my WD's with a D15: I just put new tires and rims on two of the WD's. Will 28's fit on a D 15? Nothing wrong with the WD's but I like the idea of the lower tractor and the way it its set up. THX! |

| Yes, the wheels will fit but there might be clearance problems - depends on wheel spacing, tire might rub on fender? |

| If you ever plan on moldboard plowing, the snap-coupler bell will be (too) higher and lifting links on the plow too short. Also you will have to run a slower gear because your speed will be increased. |

| I traded a WD in on a D-15. Best decision I ever made! |

What a step up!! You won’t regret it. D15 is a work horse for its size. Ours has pulled a 3 bottom Oliver plow for many years in 2nd HI range(4th). Great hydraulics and the Power Crator engine has plenty of low end torque. ------------- 1968 B-208, 1976 720 (2 of them)Danco brush hog, single bottom plow,52" snow thrower, belly mower,rear tine tiller, rear blade, front blade, 57"sickle bar,1983 917 hydro, 1968 7hp sno-bee, 1968 190XTD |

Steve A, If you can get a D15 with power steering, that tractor would be your go to Allis! I really like our D14 even sans power steering. Good luck with your hunt. They are out there.

And to take Sugarmakers comment one step farther, if your newly acquired D-15 happen to be a Ser,II, you would have the best of all. The Ser.II usually has Power Steering, it has a bigger Engine ( 160 vs 149 cu.in.) and a big advantage regarding your WD 28" tires, the Rear Fenders are mounted to a higher Fender Bracket. Allis raised the Fenders to allow for the larger 14.9 X 26 Tires. G |

I've 14.9x28 tires on my ser II D-15, I can't remember if I spin the rim out or not but I think I did because I put chain on her. My is use as a loader tractor and has a shuttle shift which makes life a lot easier. |

| Measured the tires on a WD45 with 14.9 X 28 and the tires on a D15 14.9 X 26 the 28" tires were 1 inch larger outside diameter. Brand these days makes a big difference as to size also. Some 26" tires how very tall side walls too. |

| Same exact brand and model of tire I would expect 2 inches difference. |

I have a couple of both. The D15 is nicer for pto work. The WD is simply the king of torque. It will do the job at idle while the D15 needs a bit more. Riding all day? The D15 wins. That tiny ring and pinion in the D15 always makes me wonder about its limits. Drawbar load? The WD handles it better. |

| Thank you all for the input. You've given me a pretty good comparison between the two and pointed out some things I was pondering about: Geometry of the snap coupler if I swapped tires and torque in particular. I've put a D series seat/frame on one of my WD's, moved the steering wheel a bit and that improved the ride and the working area. |

A hand clutch versus a power director? Hands down no comparison, D15 is way better. I have both and would give away my WD before parting with the D15 series II. ------------- 1968 B-208, 1976 720 (2 of them)Danco brush hog, single bottom plow,52" snow thrower, belly mower,rear tine tiller, rear blade, front blade, 57"sickle bar,1983 917 hydro, 1968 7hp sno-bee, 1968 190XTD |

I had 400 bu of corn in a Kilbros 375 box. One wheel of the wagon was in a hole. The D15 Series II just spun so I hooked a WD45 GAS up to the wagon and the WD45 took off with no effort .Both tractors had fluid in the tires. ------------- Fred Dunlop, G,B,CA, WC,WF, 3 WD45`s,gas, diesel and LP,U,D10 series III, D12,D14,D15 SERIES II,D17 Series IV in Gas and Diesel ,D19 GAS and D21,170 185,210 ,220 an I-600 8070 fwd, 716H and 1920H |

Just had a friend who bought a parts D15II - probably take $1000 for front end with power steering set up with tires ------------- When told "it's not the money,it's the principle", remember, it's always the money.. |

A hot rod driver could dig holes trying to start a loaded wagon with a D21. Take a clue from a locomotive starting a mile long loaded coal drag. Slow and easy does the job. Starting a rolling load in Low-Low at just off idle with the Power Director clutch will start just about anything with a D15. If one wheel is in a hole it needs to be rocked like being stuck in snow. I have a D15 II and wouldn't trade it for a barn full of WDs. ------------- If it was fun to pull in LOW gear, I could have a John Deere. Real pullers don't have speed limits. If you can't make it GO... make it SHINY |

I have never so much as even touched a D15 and around these parts of the country I probably never will. I always thought our WD was a pretty decent tractor so the D15 must be quite a machine. Of course our other tractors were an Allis Model C, a hand-start JD Model A, plus D2 and D4 Cats with hand-start pony motors.

I’m by no means saying a WD is not a good tractor, it was the tractor that really put AC on the map. WD45 even better. But the question is what’s better if compared. I have a 1952 WD, and our family D15 Series II. WD no power steering, although I bought a Charline PS for it but haven’t installed it yet. I enjoy running it for some jobs but the lack of PS makes it tiring to use. It’s best at raking hay. The D15 does any task we use it for with ease of operation. PD and 8 forward gears and 2 reverse gives better speed choices for chores. Power steering is effortless and factory 3 point allow more Implement choices. Unless you want to continue to use snap coupler Implements? ------------- 1968 B-208, 1976 720 (2 of them)Danco brush hog, single bottom plow,52" snow thrower, belly mower,rear tine tiller, rear blade, front blade, 57"sickle bar,1983 917 hydro, 1968 7hp sno-bee, 1968 190XTD |
