Conditions & Chute Clogging
Old grass on the deck can cause problems.
Regular cleaning will prevent build up and prolong the life of your mower.
Deck Wash Port
The was out port isn't fitted to all mowers.
It does a pretty good job of cleaning the underside of the deck.
Move your mower to a suitable location as it leaves a bit of a mess.
Just attach and turn on garden hose. Start your mower to engage blades.
Run until water runs clear - simple!
Lift the front of your tractor, secure it well before climbing under.
A wire brush and paint scraper does the job.
To help prevent clogging:
Option 1 - Quick fix is spray the deck with WD40, it does help but it won't last.
Option 2 - Spray deck with DuPont Teflon coating.
Option 3 - Spray the deck with bed liner, my preferred option. Works on tractors, riders and walk behind mowers.
Check Your Grassbag
Thatched grass on the inside of the bag is a common issue.
It prevents air flow through the bag which in turn prevents grass from entering the bag.
As a rough guide you should be able to see through the bag.
A stiff brush or better a pressure washer does a great job.
Check For Blade Damage
Defective blades can cause vibration, uneven cutting and poor grass collection.
Examine your blades carefully, checking for damage, misalignment, bent or broken leading and trailing edges.
A mowing blade may look OK, but they do wear.
Mowing blades are engineered to cut and move grass, as they wear they become much less efficient.
A worn blade will cause clogging.
2 in 1
If you like bagging - You need a lift blade.
3 in 1
Mulching has become quite popular, and manufacturers have responded by making a blade that try's to do it all, but doesn't quite succeed.
Mowers like a tune-up at least once per season.
What Is Power Take Off (PTO)?
Check the PTO system. The manual version is engaged by a cable. It lives on the crankshaft, right under the engine.
Check that the cable is pulling the PTO lever all the way.
Replacing the PTO isn't difficult, air tools make it look really easy.
Tractor Belt Wear Problems
A cutting deck belt that's slipping will be less efficient at collecting.
Check the belt for proper tension, cracking, glazing or contamination.
Damaged belts will cause vibration and poor general performance.
A typical deck belt might last 3 - 4 years.
