The long period will create a problem with blow by - one of the best ways is to work the hell out of it to help it, BUT in your case that may be impossible.

Is the clutch stuck?

Clutch works not stuck will work pto fine start and stop let it run maybe fifteen minutes or so maybe longer engine warmed up and running smoother less blowby just had fuel tank setting on tractor not mounted so couldn’t really do more fuel tank mounted now need to pull and clean hst filter and screen new fluid hopefully hst will work then I can live with a little blowby and oil usage for now till funds avail for rebuild or replacement engine fingers crossed

My B7100 would smoke badly too - it had about 2000 hours - the more I ran it and the harder I ran it - the smoke would lesson to a degree. Cutting grass going up a good grade will result in some "particulates" coming from the exhaust!

And the fun continues neutral return rod disconnected in tunnel beside and just behind tranny filter a little fineness and managed to get a cotter key in no washer but should hold for a while we’ll see
