Electrical system
The electrical system is a 12 volt, negative ground. Recommended battery size is a garden tractor BCI group U1R with 225 or better cranking AMP rating. A
The battery is located under the seat. Fig.
WARNING: Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to cause cancer and reproductive harm. Wash hands after handling.
WARNING: Avoid skin contact with battery acid.
Always wear eye protection when checking the battery, acid can cause serious injury to skin and eyes. If contact occurs, flush area with clean water and call physician immediately. Acid will also damage clothing.
Do not allow open flame near the battery when charging. Hydrogen gas forms inside the battery. This gas is both toxic and flammable and may cause an explosion if exposed to flame. Always remove the negative ground first and replace it last.
Do not overfill battery.
Electrolyte may overflow and damage paint, wiring or structure. When cleaning the battery, use soap and water. Be careful not to get soap and water into the battery. Use soda mixed in water to clean corrosion off the terminals.
WARNING: Shorts caused by battery terminals or metal tools touching metal tractor components can cause sparks. Sparks can cause a battery gas explosion which will result in personal injury. Prevent the battery terminals from touching any metal tractor parts when removing or installing the battery.
Do not allow metal tools to short between the battery terminals and metal tractor parts.
WARNING: Incorrect battery cable routing could cause damage to the tractor and battery cables. This can cause sparks which can cause a battery gas explosion which will result in personal injury. Always disconnect the negative (black) battery cable before disconnecting the positive (red) cable.
Common circuit failures are usually caused by shorting, corroded or dirty terminals; loose connections, defective wire insulation or broken wires. Switches, solenoids and ignition components may also fail, causing a shorted or open circuit.
Before attempting any failure diagnosis of the electrical system, use a test light or voltmeter to check the battery voltage. If the battery voltage is satisfactory, check the cleanliness and tightness of the terminals and ground connections. A general understanding of electrical servicing and use of basic test equipment is necessary for troubleshooting and repair.
Major overhaul or repair of the starting motor or alternator should be performed by trained technicians only.
Burnishing the electric clutch
WARNING: To insure maximum performance and life, it is necessary to burnish the clutch.
Super Mini Z units built with serial number 03120228 and later were built with Warner clutches. It is not necessary to burnish these clutches.
Super Mini Z units built prior to serial number 03120228 were built with Ogura clutches. Occassionally it may be necessary to burnish the clutch.
Burnishing the Ogura clutch (Fig.

voided if it is not burnished properly.
Use the following procedure to burnish the clutch:
1.Check the air gap between armature and rotor. Gap should be .012” to .024”.
2.Cycle the clutch on and off 10 times (15 seconds on and 15 seconds off) with the engine operating at half throttles, approximately 1500 rpm.
Access to engine and hydraulic pumps
The hydraulic pumps are accessed by lifting the seat platform. The seat platform is hinged at the front. To raise it, release seat latch and tilt seat platform up and forward. The seat platform catch (Fig.
WARNING: Always wear adequate eye protection when servicing the hydraulic system and battery.
