NH 6750 disc mower

I bought a new mower and have been running it but noticed after cutting for about 4 hours that the gear box was so hot you could not hold your hand on it. The oil levels are good but wondered if anyone has noticed this on yours if you have a mower like it.

I checked the oil levels before I ever started using it and have twice since and they are all on level. It has been used prolly 10 or 12 hours total now.

Thye get pretty hot, but if you are concerned call your dealer and have them come check it out in the field under operating conditions

Refilling the gear box with 80/90 Synthetic gear oil might help. Those gear boxes run pretty hot anyway.

They say to use one of two different oils and one is synthetic. I have heard that they do and when it is changed I may go to the synthetic oil. If it would cool it down it has got to be a good thing.
