While you're at it on the L2800/L3400 Bota you might want to look under between where your feet go on the deck for the suction return hose . There notorious for cracking on those and providing slow hydrolics. Hose cheap @ dealer and real easy fix .
Also search here on TBN some good threads on legally bumping up your FEL capacity. Did mine easy to do . Others here have had issues with the under seat attachment cable assembly. Also check for leaks around your site glass .
I had it's big brother the L3400 DT / STICK TRANNY . Not the hydro version . IMO really good tractor.
