Operation
Before attaching the rotary tiller to the tractor, check the unit to ensure there is oil in the top and side gear-
box. 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 adjustable
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, separate 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 reassem-
bling.
Do not shorten too much, the proper overlap is a minimum of 1/3 the length of each
profile.
