Hi all,

I need some expert advice on increasing the speed of a 5718. It travel at 19.5 MPH at top speed and I am trying to get it up to 25 MPH. Do you know if exchanging the portals with those of a smaller tractor (e.g a 3511) will achieve this?Are there different sized driver & driven gears inside the portals of smaller zetors to compensate for their smaller wheels?
I will be replacing the brake slave cylinders shortly so I could do this at the same time.
I'm trying to steer clear of modifiying the injector pump or adding larger wheels(currently has 16.9/14x30) to get the extra MPH's .
Hope you can advise.
Thanks,
John,
Ireland
