Auto Quad Transmission Clutch Pack

Deere’s Auto Quad has a good reputation for reliability and failures are rare. But if the tractor has done a lot of heavy work, clutch packs can wear.

Recently, Mr Morley tackled this problem on a 6620. The tractor had clocked up about 7,000 hours and the teeth on the clutch pack that controls third and fourxsth speed had worn to the extent that it was spinning in third.

He dropped the transmission out of the tractor, stripped it down to access the pack and then rebuilt it. The job took three days and the parts cost about 6000 USD.
