Recently, I blew a power steering hose on my 318 only to find I
had no fittings to make a new one. I have sold hundreds of these
hoses over the past several years and was all out of hose ends! The
original hoses are made from 1/4" ID hydraulic hose. The end
that screws into the steering cylinder is pretty special and has a long
So, I started digging. I found I had the correct fittings
for the larger 3/8" hose, so I made two new hoses. After
installation, it was back to mowing. I fired up and headed back to the
yard. To my surprise, the steering worked better than ever.
The tractor was easier to turn and responded quicker!
Well, I had to understand what was going on and
started thinking about how the steering worked. I began to surmise
that the hydraulic steering on these tractors is really a low pressure high
flow system. Doesn't take much pressure to turn the wheels, but the
fluid must flow quickly for the steering to be responsive. I looked
at the difference in the hose ends between 1/4" and 3/8"
and realized the 3/8" hose end is way bigger than the 1/4" hose
end. So much bigger that it makes a significant difference in the
performance of the tractor. The difference is so significant, I no
longer offer the original size hoses.
This is for TWO hose
