the gear ratios of the 540 & 1000 rpm PTO's (424, 425, 427, 435, 437) (u1000 to u2450L37 6x6) are

 

540rpm = 4.08:1

1000rpm = 2.32:1

 

thus

 

540rpm PTO = 2203rpm engine

1000rpm PTO = 2320rpm engine

 

540rpm on the 1000rpm PTO = 1252.8rpm engine.

We run our U1000 at 2400 rpm and that gives about 1300 rpm at the pto. edit

 

if 2400rpm engine then the PTO speed will be

 

2400rpm engine / 2.32 gear ratio = ~1034.5rpm @ the PTO

Is it wise to have the engine running @2400 rpm for extended periods?2500rpm in eight gear on the flat gives me 80kmph road speed,and beleive me you know your doing it!

I usually trundle around at 60kmph,as a U1000 driver trundling is about as good as it gets!:proud:

I'm no expert on this, my boss is the one with the knowledge so I will bring up this point with him, don't want to be doing the engine any harm :icon14:

We run at 2500 rpm on our u1000, with a 10" Junkarri chipper.

Top speed on the flat is just over 60kmph:thumbsdown:

 

Something wrong there, it should do 80 kmph.
