Tom;
I did a "Search This Site" (left of this page) and
here's one of the many posts on the topic, posted
by "Jack in NB" 3/20/00:
Neb tests: 35 gas weighed 5156#, pulled 3414# max
in 2nd. Max belt hp 33.24. 10.7 hp/hr per gal of fuel.
35 Diesel (3 cyl Perkins) 5909#, 3965#, 37.05 belt
hp. 15.7 hp/hr per gal. The 4 cyl Standard diesel horsepower is closer to
the gas version. The Neb folks added 1500 lb or so of weight for
testing; this would put the "empty weight" of the
gas tractor at about 3500#. I switched from the 9N/8N/s to our first 3 cyl
diesel (about '76) for the live PTO and position
control on the 3 point, and the fuel saving really
amazed me. Did the job faster, and seemed to take
half the fuel. The later 3 cyl Perkins (AD3-152 direct injection
diesel) tests showed a further 10% fuel saving -
still one of the most fuel efficient engines in
service! The three point linkage settles on all our
Masseys. Haven't seen one yet which stays up.
Nature of the beast - the lift cyl has rings like
an engine piston rather than hydraulic cyl packing. The left spool lever on the under-seat valve can
do three things: 1) non-position control of the
lift arms, 2) switch the oil flow from the side
lever controls to the right lever on the valve
bank (normal), or 3) operate another remote, with
the lift arms locked. I've not seen a lock on the right spool (but some
might have one - I learn something new about these
old girls most every day!). My guess is either a
hydraulic lock (try removing the outlet port
cap(s) and the back cover on the right spool) or
something jamming the control lever or internal spool. If it's internal, it will have to come apart, if
you need to use it. GREAT tractors!
