Long time subcriber & reader - Only my second time seeking assistance. My apologies up front for the lengthy post - I've tried to be thorough, tho....
First off:
2013 GRAVELY ZT60 HD (w/ Kawasaki FR730V)
Model: 991084
S/N: 021187
Warranty Code: HB
Hydro Gear Commercial ZT-3100 Drive System
Has 903.7 hours on a working hour meter.
I've owned it a year now. I mow a 4 acre yard about every 4-7 days from March through mid November.
I've done a full engine tune up twice now (oil, oil filter, air filter, fuel filter, plugs; and blades with blades I got with the mower & sharpened).
I have several concerns:
#1 it seems to lose power while mowing thicker grass, but not too high - level ground & unlevel ground at medium speeds. If I slow down, the revs climb back up to normal. I do not ever mow at full/high speed - although I believe this mower should be able to handle it. Doesn't burn/use any noticeable amount of oil between oil changes. I have basic tools, but nothing to check compression or tear into the engine ....
Where can I find printable/download able manuals for mower & engine?
#2 It seems to have a pretty significant vibration - at least more than I feel should be normal. The vibration is there when its running w/out PTO engaged. I believe there may be a failing spindle or pulley, possibly even both because the vibration is more notable when the PTO is engaged. The blades are not bent/warped/out of balance.
What's a good/reputable source of OEM blades, spindles, pulleys, belts - & part numbers for each?
#3 - least concerning is the last time I mowed the main belt from the PTO clutch to the deck 'jumped' off when I disengaged the PTO after a couple hours mowing. I didn't find anything broken and was able to put it back on and tested it w/out it happening again.
PTO engaged & disengaged several times after mowing for a few minutes at a time.
This is my second ZT. My first was a 50" deck Toro Time Cutter SS5000 that I bought new from a big box store.
Thanks in advance!
Ben S.
