Part of the John Deere Repair Manuals.
This 168-page John Deere Technical Manual (OEM #TM1391) covers the RX63, RX73, TX75, SX75, RX95, and SX95 riding mowers, giving you factory repair procedures for every system from engine to power train. Inside you'll find full electrical wiring diagrams, a dedicated troubleshooting section for chasing starting and PTO faults, plus a bolt torque chart and O-ring boss fitting recommendations up front so you're not guessing at fastener specs. Set the mower spindle sheave locknut to 140 N-m (103 lb-ft) and the engine sheave mounting cap screw to 73 ± 13 N-m (54 ± 10 lb-ft), then check drive belt clearance at 2.0-4.0 mm before you button it back up. No more flipping through a shop binder with missing pages while your customer's mower sits half-apart. This PDF is bookmarked and searchable, so you can jump straight to the variator adjustment or clutch linkage check without hunting.

John Deere RX63, RX73, RX95, SX75, SX95, TX75 Common Problems This Manual Covers
Blade vibrates or cuts unevenly after hitting a rock or curb
Remove the blade and check the spindle shaft and housing for bending or cracks from the impact. Fit a new blade if the old one is bent or nicked, and torque the spindle sheave locknut to 140 N·m (103 lb-ft) per page 89. Spin the deck by hand to confirm balance before starting the engine again.
Manual Section: Miscellaneous Repair p. 89Starter cranks slowly or engine turns over weak in cold weather
Test starter current draw with an inductive amp clamp; it should not exceed 150 amps per page 105. Check battery terminals and the ground strap for corrosion first, since resistance there mimics a failing starter. Replace the starter motor if draw stays above spec once terminals are clean and connections are tight.
Manual Section: Specifications and Operational Checkout p. 105Frequently Asked Questions
How do you fix john Deere riding mower won't move or wheels lock up after wheel cleaning or installation?
Check that the 3/16 in. x 2 in. wheel lock pin is seated in the axle hole, not sheared off or knocked loose during wheel service. Pull the wheel and clear packed debris or grass from the pin bore before reinserting. Confirm the pin drops fully home and the wheel spins freely once reinstalled, referencing the front wheel service steps on page 69. p. 69
How do you fix engine cranks but won't start, especially after sitting over winter?
Pull the shroud and check ignition coil air gap with a feeler gauge; it must read 0.3 mm (0.12 in.) per page 105. Reset the gap to spec if it's off, then retest for spark at the plug. If the gap checks out but spark stays weak or absent, replace the coil instead of chasing wiring faults. p. 105
How do you fix repeated hydraulic or fluid leaks at a fitting despite retightening connections?
Wipe the fitting clean and inspect the O-ring boss seat with a magnifying glass per page 14; it must be free of dirt and defects. Remove any raised nicks or burrs with a slip stone, install a fresh O-ring, and torque the fitting back down before running the system to check for renewed weeping. p. 14
How do you fix mower drive belt slips or jumps off the pulley under load?
Check primary belt clearance at the belt guide; it should run 2.0-4.0 mm (0.08-0.160 in.) off the pulley per page 46, with the secondary guide set to 1.0-2.0 mm (0.04-0.08 in.). Adjust the guide bracket if clearance is out of spec, then inspect the belt face for glazing or fraying and replace it if worn. p. 46
