Have 42 hours on my 1880. Have about 10 hours of work to do on my driveway. Appt set for service next month. Will Kubota deny warrenty claims if they see I went over a few hours for service? Am hoping I can finish in 8 hrs but wanted to check if this would be an issue. If I hit 50 hours before finishing, should I stop until the service is completed? Want them to do the 1st service and go over it good. Will do the next required service myself. Thanks.
