When I started my 2210 on Sunday, it had been standing for a month with the arms dropped. I moved the lift lever and nothing moved. I got off the tractor and lifted the 3point manually, it moved without any resistance up and down. It felt like there was air in the system. I got back on and revved the engine to about 2000 revs. The arms lifted and dropped smoothly. Only then did I put the tractor in gear, 3rd speed 1st gear, tractor moved but did start with a jerk. I then put it into reverse and backed up to my flail mower, weighs about 220 kgs or 450lbs. The arms lifted it as normal.
When I had finished, I dropped the mower in the shed and moved the tractor forward a few feet and stopped the engine, gears in neutral. After a few minutes I restarted the engine, selected 3rd speed and 1st gear. The tractor would not move, I tried different speeds and gears but to no avail.
The transmission screen filter and fluid were serviced about 20 hours ago. There is only one filter on the 2210, the spin on filter is for the engine lubrication system.
I am a newby to hydraulics so any help and advice would be much appreciated. Thanks
