Let's say that I was wanting to build a non amphibious skid steer agricultural/recreational vehicle. I plan on keeping the weight to about 600 lbs and the top speed about 25 mph. Approximately 20 hp. What are some of your learned opinions about different transmissions. I lean toward hydrostatic... mostly because of ease of design. I have read all of the negatives previously posted about hydraulics, and I would consider a mechanical system if I could find a good source for a complete unit or some ideas about what a roboust system would consist of. A T-20 is attractive, but I wonder about avaliability. I also noticed a lot of posts about problems people encounter, but I gather that is the exception rather than the rule. I'm still not sure what argo is using, or if they are commercially avaliable. Any good ideas would be appreciated. |

Fred: Your going to have a hard time making that 600lb weight limit. You won't even come close with a "juice" AATV. That oil and the rest of the stuff that goes with it is very heavy. So that is out. Lets talk trannys. The T-20 is a damn good unit. Very strong, and compact. There is quite a few around. Just call Richard up and he can set you up for a very reasonable price. The Argo has a rear end type of setup. Not really a tranny. Just an open differential so to speak. In a word, they are tough!!!! I mean really tough!!!!! Big straight cut gears!!!! Big bearings!!!! These things can handle BIG horsepower. I have one in my Argo and one in my Attex. They are both very good units. If I had to pick, I would get a T-20. They don't suck power in the turns like the "rear end" does. They arn't noisy like the Argo unit either. I have had no problems with either unit. Now; what would I use if I was building what you are? I would get a motorcycle engine and tranny setup and put it between the frame rails!!!! Get something real cheap, like a Honda 750 or something. Put a cable clutch on it and maybe an air shifter. You said you did not need it to float so that will make cooling a snap. (No ducting) Anyway, thats my 2 cents. By the way, why the 600lb limit when you don't need it to float? Thats very, very light!!!!! |

Thanks for the input, I agree that the T20 is an attractive package, what do used complete units usually go for, just out of curiousity. I was planning on keeping it at or around 600 lbs in order to minimize the ground psi and ease transportation. I assume when you say an open dif on the Agro type, you mean it is just like a dif in a truck... power goes to the side that slips... by braking on axle, it causes power to go to the other side. I also assume that they have some sort of reversible transmission. |

Fred: I have know idea what a T-20 is going for these days. Just contact Richard Clark; he will give you the best price on one. He has a great site here and is nice to talk to. About the Argo tranny; you are right on both accounts. Good luck with the project. |

If you want to buy one new from Recreatives they will probably cost you upwards of 1500.00 |
