Bucket Level Indicator
- Cleaning concrete surfaces causes rapid bucket wear. Bucket level
indicator helps to ensure bucket rides on wear pads. Adjusting Bucket
Level Indicator: Loosen cap screw. Adjust rod up or down until bend
rests in guide bracket. Tighten cap screw to hold rod securely in place.
O-Ring Installation
- Inspect groove and/or seat. Flat face O-ring seal: Apply petroleum
jelly to O-ring and place in groove. O-ring boss: Install O-ring
carefully over threads. Install fittings by hand until snug, position
adjustable fittings by unscrewing no more than one turn.
Replacing Orifice -
Orifice must be in place for more efficient use of JD 2520 tractor
hydraulics. The lift circuit orifice slows the lowering and improves
control of lift arms. Orifice, is in the head-end lift cylinder fitting
with cap color-coded blue. Flat face of orifice must be against inside
of adapter fitting. Tighten according to specifications.
Assembly Sequence -
Prepare the tractor. Install mounting frames. Install hood guard.
Prepare the 200X loader. Install bucket/attachment. Install hydraulic
hoses. Position loader to mount on tractor. Attach loader to tractor.

Installing Frontier RT1157 tiller on
2520 tractor - Back tractor into position and align

control. Fasten each draft link to draft link brackets with drilled pins
and quiklock pins. Locate driller pin in top holes. Install center link
on tiller and fasten with drilled pin and quiklock pin. Install PTO
shaft to tractor. Engage the cardan shaft and check that it is perfectly
locked on the tractor PTO. Check that the guard is free to turn and fix
it with the relative latch. Raise tiller. Remove spring locking pin from
parking stand. Slide parking stand all the way up on tiller bracket.
Fasten with spring locking pin. Level tiller. Adjust sway chains on
tractor lower draft arms to minimize side way.
PTO shaft with clutch
- The PTO shaft can be equipped with safety clutch to protect the
transmission components of the machine from stress and/or excessive
overloads. The tilt of the PTO shaft must not exceed 10 degrees. The
clutch is already pre-adjusted for average stress. If it slips too
easily (and overheats), it will be necessary to evenly tighten all the
nuts that retain the spring. The clutch disks must be changed if the
clutch still slips after all the nuts have been tightened. If the clutch
does not slip, evenly unscrew all the spring fixing nuts. Unscrew one
turn at a time and check the clutch after having worked about 300
meters. Repeat the operation if necessary, remembering to unscrew one
turn at a time. If the clutch maintains a temperature of about 40-50C
(104-122F) degrees during work, this means that it has been correctly
regulated.
