Westwood Ride On Mower Back Axle/ Gearbox

Westwood gearbox/ back axle from 11HP ride on mower. Tyre treads are good but cracks in the tyre walls (see photos). I bought the complete mower for the front axle and was told the whole thing worked when it was parked up but I can give no guarantees regarding condition. It has integral disc brake and all turns freely. Collection only.
