Do not operate this Equipment with hydraulic oil or fuel leaking. Oil

and fuel are explosive and their presence could present a hazard. Do

not check for leaks with your hand! High-pressure oil streams from

breaks in the line could penetrate the skin and cause tissue damage

including gangrene. To check for a hose leak, SHUT the unit ENGINE

OFF and remove all hydr aul ic p ressure. Wear oil impenetr ab le glo ves,

safety glasses and use Cardboard to check for evidence of oil le aks. If

you suspect a leak, REMOVE the HOSE and have it teste d at a Dealer.

If oil does penetrate the skin, have the injury treated immediately by a

physician knowledgeable and skilled in this procedure. (SG-15)

A minimum of 20% total tractor weight must be maintained on the tractor front end at all times. Front end

weight is critical to maintain steering control and to prevent the tractor from rearing up while driving. If the

front end is too light, add weight until a minimum of 20% total weight is reached on the front tires. Front

weights an d weight carriers can be purchase d through an authorized tractor dealership. OPS-U- 0005

Depending on the unit, the mower is designed to operate at a PTO speed of 540 or 1000 RPM. Most tractors

operate at either 540, or a combination of 540 and 1000 RPM PTO speeds. The operating speed of the

mower and tractor can be determined by the number of splines on the driveline yoke and PTO output shaft.

Those operating at 540 RPM will have a 6-spline shaft and thos e operating at 1000 RPM will have a 21-spline

shaft or a 1-3/4” 2 0 sp line shaf t. Refer to the tr actor owne r’s manual for instructio ns to chan ge PTO spee ds on

models that operate at more than one speed.

If operating an older model tractor where the tractor’s transmission and PTO utilize one master clutch, an

over-running clutch must be used between the PTO output shaft and the driveline of the mower. An

authorized tractor dealer can provide the over-running clutch and its installation if needed. OPS-U- 0006
