Service jobs and parts

PTO shaft lubrication and check

PTO shaft · every 10 hours

Kuhn's 2019 manual: check and grease the PTO shaft after the first 10 hours, then every 10 hours, at the start of each season and after pressure washing. The 2009 manual said every 20 hours; this uses the shorter figure.

Part	Qty	Notes	Part number
Grease	1	Adhesive multi-purpose grease	check your handbook

Step-by-step

Lower the Haybob to the ground, disengage the PTO, stop the tractor engine and take the key out. Wait until the rotors have stopped.
Take the PTO shaft off both the machine and the tractor.
Check the shaft and guards for wear and damage. Replace damaged guards before use.
Grease the joints and the grease point on the guard, and the sliding surfaces of the protection tubes.
Check the tubes slide properly and the profile tubes are well greased.
Follow the PTO shaft maker's own manual as well.

Tools: Grease gun, Rags

Bolt, tine nut and rotor bolt tightening

Tines · every 150 hours or every year

Kuhn: tighten all bolts and nuts after the first 5 and 10 hours, every 150 hours, at the start of each season and after any bolt has been undone. The 2009 manual singles out the tine nuts and the rotor bolts under the rotor tops.

Step-by-step

Lower the Haybob to the ground, disengage the PTO, stop the tractor engine and take the key out. Wait until the rotors have stopped.
Tighten every bolt and nut to the torque in your handbook's table (grade 8.8 bolts).
Pay special attention to the nuts holding the tines and the bolts under the top of each rotor that hold the rotors on.
Replace missing or broken bolts with genuine ones.
On a new or rebuilt machine, do this after the first 5 and 10 hours.

Tools: Torque wrench, Spanners

Tine check and replacement

Tines · every year

The Haybob has 4 different tines, 5 of each. Blue-marked tines go on the left rotor and yellow-marked ones on the right, alternating narrow and wide.

Part	Qty	Notes	Part number
Tine, left-hand, narrow	5	As printed in the 2009 manual. The manual also says adding E gives the cheaper B-quality tine, so confirm the suffix with your dealer	PZ 107E
Tine, left-hand, wide	5	As printed in the 2009 manual; see note above	PZ 110E
Tine, right-hand, narrow	5	As printed in the 2009 manual; see note above	PZ 224E
Tine, right-hand, wide	5	As printed in the 2009 manual; see note above	PZ 225E

Step-by-step

Lower the Haybob to the ground, disengage the PTO, stop the tractor engine and take the key out. Wait until the rotors have stopped.
Wear gloves. Check every tine for cracks, bends and wear.
Blue-marked tines go on the left rotor, yellow-marked on the right. Narrow and wide tines alternate.
Fit each tine with the short finger up and the long finger down, and the bend near its fixing bolt.
Tighten the tine nuts and check them again after a few hours.

Tools: Spanners, Torque wrench, Gloves

Start-of-season check

Storage · every year

Kuhn's start-of-season check.

Step-by-step

Hitch the Haybob and run the tractor hydraulics at idle.
Run the machine at 350 rpm for a few minutes. Check everything works and listen for odd noises.
Switch off the hydraulics and the PTO, stop the engine and take the key out. Wait until the rotors have stopped.
Tighten all bolted connections (see the bolt task).
Check and grease the PTO shaft.
Check the safety decals and lights are in place and clean.

Tools: Torque wrench, Spanners, Grease gun

Cleaning and parking

Storage · every year

Kuhn's parking steps. Neither manual gives a fuller lay-up list.

Part	Qty	Notes	Part number
Grease	1	Adhesive multi-purpose	check your handbook

Step-by-step

Lower the Haybob, disengage the PTO, stop the tractor engine and take the key out. Wait until the rotors have stopped.
Clean the whole machine. If you pressure wash it, grease the PTO shaft afterwards.
Park it on dry, firm ground, away from where people work, with the jack stand down.
Lower it fully on the linkage, put the PTO shaft in its rest and unhitch.
Keep children away from the parked machine.

Tools: Brush, Grease gun

Known problems

Mixed-up tines

Four tine types and two colour codes. Tines on the wrong rotor or in the wrong order rake badly.

Rotor bolts

The bolts holding the rotors sit under the rotor tops and are easy to miss. Check them with the tine nuts.

Repair guides

Tine breakage and tine fitting order (Easy, 30 minutes to 2 hours): Tines breaking or bending, poor tedding or raking, or tines fitted in the wrong place after a repair.
Rotor wobble or knocking: rotor bolts and tine nuts (Easy, 30 minutes to 1 hour): A rotor wobbles or knocks, tines work loose, or bolts are missing.
PTO shaft and friction clutch checks (Easy, 30 minutes): The PTO friction clutch slips, the shaft guard is damaged, or the shaft tubes stick.

The full step-by-step guides are in Farmyard Workshop once you add your implement.
