I have a Ransomes 723d front deck mower. Loftness, I believe, makes a snowblower that attaches to these mowers. Problem is, I haven't been able to find any for sale. They always seem to sell with the mower. I'm trying to find another, more readily available snowblower that I can adapt to the ransomes. In order to cover the tire tracks, blower needs to be a minimum of 52" wide.
I don't really have any concerns about fabricating mounting arms and lift bracket to fit anything. The problem will be power transmission. The blower will have to be shaft drive with clockwise rotation as you look at the back of the snowblower. This is just opposite of 3PH blowers, so I need to find something originally made for the front of a tractor, or riding lawn mower.
My drive shaft is also direct off of the flywheel of the engine, so shaft speed is exactly what the engine speed is. Top speed on the Perkins diesel is supposedly 3000 rpm. I can't verify this as the mower doesn't have a tach. However, if that is close, I'd think that the shaft speed is around 2600-2800 allowing for the drag of the hydro which is driven off a belt from the drive shaft, and the electric clutch as well as the mower/blower. I've seen possible candidates from John Deere (59 and 60" wide), Cub Cadet (54") and Kubota (various). I'm aware of different blowers using both gear boxes that reverse rotation between the shaft and the blower, and others that use a chain drive that keeps rotation direction the same, but just reduces the rotation speed.
Does anyone have experience with any of these blowers that would enable me to pick the right unit as far as shaft rotation and speed. I could see that I wouldn't want to hook on to something built for 1000 RPM and turn it 2500-3000! I have heard that some of the JD's were made for 2000 input speed, is that correct? If so, that might be close enough as a big gulp
of snow would probably slow it down some.
Thanks
