When I was in the motor trade, sticking clutches often happened after storage! The best way to free the clutch? First run the engine until it worms up. 2nd, jack up one rear wheel above the ground. Use solid axle stands. 3rd, select top gear siting on the seat and depress your clutch fully. 4th, with the clutch depressed: start your engine,!!! This works, due the backlash going throughout the gear train. Take it out of gear, You have just learned an old trick, which saves a lot of work/money. Enjoy 🔧🇬🇧😁
Water goes in around the gear stick rubber and the hydraulic pump have a filter go through the side plate behind the pto lever have a look and you need to clean to top of the tractor down before lifting to to or you will get dirt in the tractor
SOMETIMES NOT EVEN THE PUMP. THE CLUTCH. ESPECIALLY 2 STAGE.. YOU HAVE TO MAKE SURE THE PTO IS TURNING AT REAR WITH FORCE..... I KNOW THIS IS A WHILE BACK THOUGH....... or WHAT WAS THE PROBLEM
