Hey everyone.<br>
<br>
I'm an irrigation contractor and need to be able to trench 2-1/2" wide by 8" deep over long distances (some subdivision entrances can total almost 3/4 of a mile). I'm in Myrtle Beach, SC so I mostly trench in dirt/sand or gumbo clay. (very few rocks but some healthy roots) <br>
<br>
I have a craftsman GT5000 garden tractor with a 27 hp engine and extra heavy duty manual transmission. I'm thinking of mounting the Bolton power equipment 3 pt PTO trencher on an Agri-Fab 3 point trailer and towing it behind the tractor. The trailer has a winch to raise and lower the trencher. The trencher requires at lease 21hp at the PTO turning at either 540 or 1000 rpm. <br>
<br>
I think that I could mount an engine with some type of clutch mechanism (or hydraulics?) to take the place of a tractor's PTO.<br>
I don't have a lot of knowledge as to engines, transmissions, hydraulics, etc so what I need to know is this:<br>
<br>
If an ordinary engine turning at 3600 rpm is rated at 4hp will it achieve 24hp if it's geared down to 600 rpm (standard 6:1 reduction available from most engine manufacturers)It seems to me that it should based on the formula: HP = Torque X (RPM/63025); and<br>
<br>
What would be the best way to connect the 3 pt trencher implement to the engine (belts, geared clutch, hydraulics, etc).<br>
<br>
I sure would appreciate any help anyone can give me.<br>
<br>
Thanks<br>
<br>
