Westwood D1200 Mower, Ride On Tractor, Diesel, Lombardini Engine

Westwood D1200 diesel ride on mower I bought this from ebay about 6 months ago, as a non runner. Some employees of mine spent about a day working on it, changed the oil, diesel , air filter and it started right up, we then went onto totally refurbish the whole machine including1.New Battery2.New seat3.Steering wheel4.Electrics5.Cutting deck, sand blasted repainted, blades serviced6.New brake shoes7.Chassis painted8.Steering and wheels greased 9. Rear spot fitted Unfortunately after cutting about 6 acres on its first proper test the engine stopped and will not start, it would seem to be partially seized.It is possible to repair the engine or possibly replace, however I dont have the time, this would be a great project for someone.Any questions please ask [email protected] too big to post so cash on collection would be best, I will require 10% of final price by paypal within 2 hours of auction end. Merry Christmas
