My company has dealt with Curtis Cabs for many years and I have to say they are one of the better "aftermarket" cabs out there. I have installed many of these cabs on everything from garden tractors to large compact utility tractors. If installed correctly these cabs will NOT leak water inside, and have do have a lot of ventilation options to control cab temperature. The front and rear windows along with door windows open. If you wanted to for the summer months the doors come off very easily, and you could take out back and even front windows for more air flow. On second thought if you had a couple of people to help the whole cab can be lifted off tractor after removing a couple of bolts. There are also many options available, if you want a heater for cab make sure its a coolant type heater.. These are more reliable and will not kill the alternator like an electric heater can. Anyways, I am not trying to sell Curtis to you but I do like their product.. Oh and dont buy a Femco cab... what a joke...
