(2.3) Tractor Horsepower; (2.4) 3-Point Hitch; (2.6) Front End Weight - Schulte SRW800 Operator’s Manual With Parts Listing

2.3 Tractor Horsepower
The horsepower required to operate the implement depends on several operating factors including terrain condition,
operator experience, condition of the implement and tractor, and other factors. The recommended tractor HP for
the SRW800 is 35-100 HP (30-60 kW). Operating the implement with a larger tractor will greatly increase the risk
of damaging the implement.
2.4 3-Point Hitch
The tractor 3-point hitch must be rated to lift at least
1550 lbs (703 kg). if attaching a SRW800 Rock
Windrower.
The windrower can attach to tractor's with either a CAT
I or II hitch, and CAT I and II quick hitch. The windrower
comes with CAT I pins, with bushings for CAT II. For
CAT I 3-pt, CAT II 3-pt, and CAT II quick hitch, mount
the pins outward. For CAT I quick hitch, mount the
pins inward. Refer to the tractor operator's manual for
the category of the tractor used. If the hitch does not
conform to ASAE Cat I or II dimensions, the implement
may not fit or raise properly. Consult an authorized
dealer for possible modification procedures to mount
nonconforming hitches.
Use the correct hitch pins for the hitch category being
used. For a Cat I hitch, 7/8" lower and 3/4" upper
diameter hitch pins are used and Cat II hitches require
1-1/8" lower and 1" upper diameter hitch pins. CAT II
Quick Hitch width inside lug to lug should be 32 5/8".

Height from bottom hitch pin to top pin ................ 18"
Lower pin diameter ............................................. 7/8"
Upper pin diameter ............................................. 3/4"

2.5 Tractor Hyrdaulics
The windrower drum can be set at different angles from 0° to 18° using the hydraulic cylinder on the windrower. The
cylinder is operated by the tractor hydraulic pump. The tractor requires a 5 gpm @ 1800 psi, dual remote outlet.
2.6 Front End Weight
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 and weight
carriers can be purchased through an authorized tractor dealership.
