Operation - Tar River 60 Series Operator's Manual

Before attaching the rotary tiller to the tractor, check the unit to ensure there is oil in the top and
side gearbox. See Maintenance section for lubricant specifications.
Before beginning operation, check oil and grease points.
Oil level: Top gearbox 1 1/2" from the end of the dip stick.
When sitting slightly tilted forward, oil should at the bottom of the fill plug on the side gearbox cover.
Grease: Right Rotor bearing, PTO shaft Cross & Bearings
Attaching to the tractor
1.
With the Rotary Tiller on a level surface, back the Cat. 1 tractor so the tractor lift arms are even with the unit's
lower hitch pins. Lower or raise the tractor hitch arms until the 7/8" bushing in the arm is inside the clevis of
lower hitch points. Be sure nothing is between the tractor and the tiller before backing up.
2.
Insert the lower hitch pin through the lower hitch blocks and the tractor arm. The YCT series tillers have ad-
justable lower hitch blocks that can be slide to facilitate usage on larger tractors.
3.
Secure the lift arm in place by using a 7/16" lynch pin or other fastener.
4.
Repeat with the other arm.
5.
Connect the driveline to the tractor's PTO output shaft. Secure it in place.
6.
Connect the tractor top link to the upper hitch point of the rotary tiller.
7.
Start the tractor and slowly raise the tiller. Check for drawbar interference. Be sure that the PTO driveline
does not bottom out when lifting the machine to it's maximum height. If it does appear that it could bottom
out, it is necessary to shorten the PTO driveline. (See Shortening a PTO Driveline section). Ensure that in the
working position there is an overlap of a minimum of 1/3 the length of each profile.
Shortening a PTO Driveline
1.
With
the implement attached to the tractor's three
point hitch, and the PTO driveline not installed, sepa-
rate the PTO driveline. Attach the implement end to
the implement and the other end to the tractor PTO
input shaft.
2.
Raise the implement by using the tractor's hydraulic
3-point hitch to it's maximum lift height.
3.
Hold the half shafts next to each other and mark them
so each end is approximately ½" from hitting the end
of the telescopic profiles.
4.
Shorten the inner and out guard tubes equally.
5.
Shorten the inner and outer profiles by the same
length as the guard tubes. Using a rattail file, round
off all sharp edges and burrs. Grease the telescopic
profile generously before reassembling.
Do not shorten too much, the proper overlap is a minimum of 1/3 the length of each profile.
Caution: Slip Clutches may become hot. Do Not Touch. Keep the slip clutch area clear of an material that
may catch fire.
Slip clutches have adjustable torque settings. The torque setting varies with the different compression of
each spring. All the springs should have an equal amount of compression.
IMPORTANT: Do not over-tighten the compression nuts as this may impair performance or cause prema-
