I think Rob has the answer: your landscaper probably put adjustable flow restrictors in the FEL circuits. I did the same thing on my little Kubota B2400 because at medium to high engine speeds the FEL moves too fast (or maybe I just move too slow) because the cheap Husco valve does not have feathering spools. So I installed an adjustable, pressure compensated flow control valve in the raise and lower sides of the boom circuit. The Parker inline valve screwed right into the Husco valve body (with an appropriate ORB/NPT adapter) and the quick disconnects connect to the flow control valve.

I run a Mitsubishi MT180D and my FEL was real slow.

Research showed that the crankshaft pulley was designed to run an optional 'clutched' front PTO (as for snow blower)

I fabbed an attachement to replicate the factory part and drove a larger hydraulic pump that I mounted using a U-joint and splined shaft.
My FEL had a built in reservoir in one of the posts, so I simply re-plumbed the loader valves to the new pump.
This resulted in abour 50% increase in loader operation speeds.(and frees up factory pump for my planned power steering project).

Have been operating this dual pump installation for about 7 years without a hickup.
And believe me since I added a homemade tooth bar I really use it a lot to excavate tough soil conditions (and rocks).
Just this spring I extracted a boulder (about 3' x 3' x 4') that I could only roll due to the weight!
