Can anyone tell me what is under the floor on a John Deere 650G Dozer... I am doing a Demo Job and this machine was left on the property along with other equipment and it's in very good shape but the metal floor board in front of the seat is missing and all that's in there is a driveshaft with a universal joint on it coming from the rear trans and on front towards the motor it's just a spline where a driveshaft would go in so did someone just take the driveshaft out or is there a Pump, Motor, etc missing...???...I am familiar with this machine since I helped repair a JD 450 and we removed the trans to fix a broken brake but I forgot what was under the floor...t/y...
