We've got a 6910 powershift. Only twice we've had a problem and that was sorted first time by cleaning the multi plug under the gear shift and second time filter change.
Nice to drive and use.

I was invited on a tour of the American factories by JD in the 1980's to celebrate the 25 years anniversary of Powershift.

We met the bloke who had designed it in the 1960's.
He explained to us that the weakest point in the transmission was the 3 small gears that were the primary drive between the engine and the powershift clutch packs. "Don't nail the suckers to the ground with dual wheels," he said "The 'shearbolt' in the system is between the tyres and the ground, not the teeth on those 3 small gears!"

Having said that, we put thousands of hours on a 4055 and 4955 back then and never had a problem.

Great transmission, it's stood the test of time and always the right gear for the job.

The semi-powershift shift (JD power quad) has been imposed on the total powershift by the forward-reverse steering inverter. It is much more practical to pull the inverter in one direction or the other than to go through all the points of the powershift to reach the reverse gears. It is also easier and cheaper to manufacture

Contractor i used to work for in the uni summers had a 7700 powershift and it had a mind of its own as to when it would take up drive, crossing main roads or pulling out of junctions was lethal, they swapped it for a powerquad after only a year

Despite an average growing year for most crops, many growers managed to go above and beyond their predicted max yields, with Lincolnshire grower Tim Lamyman taking the top spots for his wheat yields and his world record breaking winter barley yield.

The highest cereal and oilseed yields achieved at harvest 2021 were announced at this year’s Yield Enhancement Network (YEN) Awards on Wednesday 24th November at the Croptec Show. With award presentations by Tom Bradshaw, Vice President of NFU, 24 farms took home the evening’s top awards for highest yield and highest potential yield achieved for wheat, winter and spring barley, oats, and oilseed. The 2021 winners came from all corners of the UK, as well as from as far afield as Finland and New Zealand.
